Knowing What We Know

Scientific research is a critical tool for successfully navigating our complex world. Without it, we would be forced to rely solely on intuition, other people’s authority, and blind luck. While many of us feel confident in our abilities to decipher and interact with the world around us, history is filled with examples of how very wrong we can be when we fail to recognize the need for evidence in supporting claims.  For example, even today, some individuals believe that newborn infants can only see the colors black and white.  However, Bower (1966) [1] demonstrated that while limited, newborn infants do have the ability to see color.

The goal of all scientists is to better understand the world around them. Psychologists focus their attention on understanding behavior, as well as the cognitive (mental) and physiological (body) processes that underlie behavior. In contrast to other methods that people use to understand the behavior of others, such as intuition and personal experience, the hallmark of scientific research is that there is evidence to support a claim. Scientific knowledge is  empirical : It is grounded in objective, tangible evidence that can be observed time and time again, regardless of who is observing.

While behavior is observable, the mind is not. If someone is crying, we can see behavior. However, the reason for the behavior is more difficult to determine. Is the person crying due to being sad, in pain, or happy? Sometimes we can learn the reason for someone’s behavior by simply asking a question, like “Why are you crying?” However, there are situations in which an individual is either uncomfortable or unwilling to answer the question honestly or is incapable of answering. For example, infants would not be able to explain why they are crying. In such circumstances, the psychologist must be creative in finding ways to better understand behavior.

Scientific knowledge is advanced through a process known as the scientific method . Basically, ideas (in the form of theories and hypotheses are tested against the real world (in the form of empirical observations, and those empirical observations lead to more ideas that are tested against the real world, and so on.

The basic steps in the scientific method are:

• Observe a natural phenomenon and define a question about it
• Make a hypothesis, or potential solution to the question
• Test the hypothesis
• If the hypothesis is true, find more evidence or find counter-evidence
• If the hypothesis is false, create a new hypothesis or try again
• Draw conclusions and repeat–the scientific method is never-ending, and no result is ever considered perfect

In order to ask an important question that may improve our understanding of the world, a researcher must first observe natural phenomena. By making observations, a researcher can define a useful question. After finding a question to answer, the researcher can then make a prediction in the form of a hypothesis about what he or she thinks the answer will be. This prediction is usually a statement about the relationship between two or more variables. After making a hypothesis, the researcher will then design an experiment to test his or her hypothesis and evaluate the data gathered. These data will either support or refute the hypothesis. Based on the conclusions drawn from the data, the researcher will then find more evidence to support the hypothesis, look for counterevidence to further strengthen the hypothesis, revise the hypothesis and create a new experiment, or continue to incorporate the information gathered to answer the research question.

Flowchart Outlining the Steps of the Scientific Method

The Basic Principles of the Scientific Method

Two key concepts in the scientific approach are theory and hypothesis . A theory is a well-developed set of ideas that propose an explanation for observed phenomena that can be used to make predictions about future observations. A hypothesis is a testable prediction that is arrived at logically from a theory. It is often worded as an if-then statement (e.g., if I study all night, I will get a passing grade on the test). The hypothesis is extremely important because it bridges the gap between the realm of ideas and the real world. As specific hypotheses are tested, theories are modified and refined to reflect and incorporate the result of these tests.

The Relationship Between Observation, Theory, Hypothesis and Research

Applying the Scientific Method

To see how this process works, let’s consider a specific theory and a hypothesis that might be generated from that theory. The James-Lange theory of emotion asserts that emotional experience relies on the physiological arousal associated with the emotional state. If you walked out of your home and discovered a very aggressive snake waiting on your doorstep, your heart would begin to race and your stomach would churn. According to the James-Lange theory, these physiological changes would result in your feeling of fear. A hypothesis that could be derived from this theory might be that a person who is unaware of the physiological arousal that the sight of the snake elicits will not feel fear.

Remember that a good scientific hypothesis is falsifiable , or capable of being shown to be incorrect. Recall from Chapter 1 that Sigmund Freud had lots of interesting ideas to explain various human behaviors. However, a major criticism of Freud’s theories is that many of his ideas are not falsifiable; for example, it is impossible to imagine empirical observations that would disprove the existence of the id, the ego, and the superego—the three elements of personality described in Freud’s theories. Despite this, Freud’s theories are widely taught in introductory psychology texts because of their historical significance for personality psychology and psychotherapy, and these remain the root of all modern forms of therapy.

Why the Scientific Method Is Important for Psychology

The use of the scientific method is one of the main features that separates modern psychology from earlier philosophical inquiries about the mind. Compared to chemistry, physics, and other “natural sciences,” psychology has long been considered one of the “social sciences” because of the subjective nature of the things it seeks to study. Many of the concepts that psychologists are interested in—such as aspects of the human mind, behavior, and emotions—are subjective and cannot be directly measured. Psychologists often rely instead on behavioral observations and self-reported data, which are considered by some to be illegitimate or lacking in methodological rigor. Applying the scientific method to psychology, therefore, helps to standardize the approach to understanding its very different types of information.

The scientific method allows psychological data to be replicated and confirmed in many instances, under different circumstances, and by a variety of researchers. Through replication of experiments, new generations of psychologists can reduce errors and broaden the applicability of theories. It also allows theories to be tested and validated instead of simply being conjectures that could never be verified or falsified. All of this allows psychologists to gain a stronger understanding of how the human mind works.

Scientific articles published in journals and psychology papers written in the style of the American Psychological Association (i.e., in “APA style”) are structured around the scientific method. These papers include an Introduction, which introduces the background information and outlines the hypotheses; a Methods section, which outlines the specifics of how the experiment was conducted to test the hypothesis; a Results section, which includes the statistics that tested the hypothesis and state whether it was supported or not supported, and a Discussion and Conclusion, which state the implications of finding support for, or no support for, the hypothesis. Writing articles and papers that adhere to the scientific method makes it easy for future researchers to repeat the study and attempt to replicate the results. [2]

General Research Methodologies: Qualitative and Quantitative Research Methods

Qualitative methods of research involve using a more open, evolving approach to finding out about the world. There is less emphasis on quantifying what is known and more emphasis on tapping into the experiences, assumptions, and meanings subjects give to their situations. Qualitative methods can be used to explore an area about which little is known or to get a fresh look at a situation that has been studied before. The use of narratives in which the researcher tries to find out what is going on by using the subjects’ own words is one approach. Qualitative methods are used in anthropology, education, nursing, and other areas where the researcher wishes to be led by the participants into seeing what they deem as important.

The researcher begins with a broad interest and gains entrance into a setting in which to explore. Information is gathered using a variety of techniques such as observation, documenting the physical space and surroundings of that setting, recording interviews, etc. After gathering general information, the researcher may decide to focus more closely on specific research questions. Patterns may become apparent as the researcher revisits their field notes and spends more time in a setting. These prompt the researcher to explore new ideas until they feel they reach a point of saturation, or a feeling that they’ve thoroughly explored the situation. Patterns and answers to research questions are noted in a report of the findings.

Researchers who use qualitative methods might take the following steps when conducting research:

• Begin with a broad area of interest
• Gain entrance into a group to be researched
• Gather field notes about the setting, the people, the structure, the activities or other areas of interest
• Ask open ended, broad “grand tour” types of questions when interviewing subjects
• Modify research questions as study continues
• Note patterns or consistencies
• Explore new areas deemed important by the people being observed
• Report findings

In this type of research, theoretical ideas are “grounded” in the experiences of the participants. The researcher is the student and the people in the setting are the teachers as they inform the researcher of their world (Glazer & Strauss, 1967). Researchers are to be aware of their own biases and assumptions, acknowledge them and bracket them in efforts to keep them from limiting accuracy in reporting. Sometimes qualitative studies are used initially to explore a topic and more quantitative studies are used to test or explain what was first described.

Quantitative methods involve beginning with a research question, reviewing the literature to see what others have found in their research of the topic, determining specifically what aspect of the topic to explore in your research and determining the most appropriate method to use for your purposes, conducting the study, which means finding your sample, administering your survey or conducting your experiments, interpreting the results by analyzing your data, drawing conclusions about what you have found, and finally sharing your findings with others in the scientific community by publishing your research.

Researchers using quantitative methods typically take the following steps when conducting research:

• Determining a research question
• Reviewing previous studies addressing the topic in question (known as a literature review)
• Determining a method of gathering information
• Conducting the study
• Interpreting results
• Drawing conclusions; stating limitations of the study and suggestions for future research
• Making your findings available to others (both to share information and to have your work scrutinized by others)

This model of scientific investigation presents research as a linear process guided by a specific research question or hypothesis, and it typically involves quantifying or using statistics to understand and report what has been studied. Many academic journals publish reports on studies conducted in this manner and a good way to become more familiar with these steps is to look at journal articles which will be written in sections that follow these 7 steps. [3]

Specific Research Methodologies

A research design is the specific method a researcher uses to collect, analyze, and interpret data. Psychologists use three major types of research designs in their research, and each provides an essential avenue for scientific investigation. Descriptive or qualitative research is research that describes what is occurring at a point in time. Correlational research is research designed to discover relationships among variables and to allow the prediction of future events from present knowledge. Experimental research is research in which a researcher manipulates one or more variables to see their effects. Each of the three research designs varies according to its strengths and limitations. [3]

Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. For example, studies that rely primarily on observation produce incredible amounts of information, but the ability to apply this information to the larger population is somewhat limited because of small sample sizes. Survey research, on the other hand, allows researchers to easily collect data from relatively large samples. While this allows for results to be generalized to the larger population more easily, the information that can be collected on any given survey is somewhat limited and subject to problems associated with any type of self-reported data. Some researchers conduct archival research by using existing records. While this can be a fairly inexpensive way to collect data that can provide insight into a number of research questions, researchers using this approach have no control on how or what kind of data was collected.

Correlational research can find a relationship between two variables, but the only way a researcher can claim that the relationship between the variables is cause and effect is to perform an experiment. In experimental research, which will be discussed later in the text, there is a tremendous amount of control over variables of interest. While this is a powerful approach, experiments are often conducted in very artificial settings. This calls into question the validity of experimental findings with regard to how they would apply in real-world settings. In addition, many of the questions that psychologists would like to answer cannot be pursued through experimental research because of ethical concerns.

Descriptive or Qualitative Research

Descriptive or qualitative research methods include the case study , naturalistic observation/observational research , surveys , interviews , psychophysiological assessments , and secondary/ content analysis or archival research .

Case Study Methodology

In 2011, the  New York Times  published a feature story on Krista and Tatiana Hogan, Canadian twin girls. These particular twins are unique because Krista and Tatiana are conjoined twins, connected at the head. There is evidence that the two girls are connected in a part of the brain called the thalamus, which is a major sensory relay center. Most incoming sensory information is sent through the thalamus before reaching higher regions of the cerebral cortex for processing.

The implications of this potential connection mean that it might be possible for one twin to experience the sensations of the other twin. For instance, if Krista is watching a particularly funny television program, Tatiana might smile or laugh even if she is not watching the program. This particular possibility has piqued the interest of many neuroscientists who seek to understand how the brain uses sensory information.

These twins represent an enormous resource in the study of the brain, and since their condition is very rare, it is likely that as long as their family agrees, scientists will follow these girls very closely throughout their lives to gain as much information as possible (Dominus, 2011).

In observational research, scientists are conducting a clinical or   case study  when they focus on one person or just a few individuals. Indeed, some scientists spend their entire careers studying just 10–20 individuals. Why would they do this? Obviously, when they focus their attention on a very small number of people, they can gain a tremendous amount of insight into those cases. The richness of information that is collected in clinical or case studies is unmatched by any other single research method. This allows the researcher to have a very deep understanding of the individuals and the particular phenomenon being studied.

If clinical or case studies provide so much information, why are they not more frequent among researchers? As it turns out, the major benefit of this particular approach is also a weakness. As mentioned earlier, this approach is often used when studying individuals who are interesting to researchers because they have a rare characteristic. Therefore, the individuals who serve as the focus of case studies are not like most other people. If scientists ultimately want to explain all behavior, focusing attention on such a special group of people can make it difficult to generalize any observations to the larger population as a whole. Generalizing refers to the ability to apply the findings of a particular research project to larger segments of society. Again, case studies provide enormous amounts of information, but since the cases are so specific, the potential to apply what’s learned to the average person may be very limited. [5]

How is the Case Study Conducted?

The procedure used in a case study means that the researcher provides a description of the behavior. This comes from interviews and other sources, such as observation.

The client also reports detail of events from his or her point of view. The researcher then writes up the information from both sources above as the case study and interprets the information.  The research may also continue for an extended period of time, so processes and developments can be studied as they happen.

Amongst the sources of data the psychologist is likely to turn to when carrying out a case study are observations of a person’s daily routine, unstructured interviews with the participant herself (and with people who know her), diaries, personal notes (e.g. letters, photographs, notes) or official document (e.g. case notes, clinical notes, appraisal reports).

The case study method often involves simply observing what happens to, or reconstructing the case history of a single participant or group of individuals (such as a school class or a specific social group), i.e. the idiographic approach.

The interview is also an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.

Most of this information is likely to be qualitative (i.e. verbal description rather than measurement) but the psychologist might collect numerical data as well.

Strengths of Case Studies

• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research which only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension to experience which is so important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is therefore important for psychologists who adopt a holistic point of view (i.e. humanistic psychologists).

Limitations of Case Studies

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feeling may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted on the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e. descriptive) data a lot depends on the interpretation the psychologist places on the information she has acquired.

This means that there is a lot of scope for observer bias and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit the particular theories about behavior (e.g. Little Hans).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory. [4]

Naturalistic Observations/ Observational Research Methodology

Observational studies involve watching and recording the actions of participants. This may take place in the natural setting, such as observing children at play at a park, or behind a one-way glass while children are at play in a laboratory playroom. The researcher may follow a checklist and record the frequency and duration of events (perhaps how many conflicts occur among 2- year-olds) or may observe and record as much as possible about an event (such as observing children in a classroom and capturing the details about the room design and what the children and teachers are doing and saying). [5]

We want our researcher to be inconspicuous—perhaps, as mentioned above standing behind one-way glass. This type of observational study is called  naturalistic observation : observing behavior in its natural setting. To better understand peer exclusion, Suzanne Fanger collaborated with colleagues at the University of Texas to observe the behavior of preschool children on a playground. How did the observers remain inconspicuous over the duration of the study? They equipped a few of the children with wireless microphones (which the children quickly forgot about) and observed while taking notes from a distance. Also, the children in that particular preschool (a “laboratory preschool”) were accustomed to having observers on the playground (Fanger, Frankel, & Hazen, 2012).

It is critical that the observer be as unobtrusive and as inconspicuous as possible: when people know they are being watched, they are less likely to behave naturally. If you have any doubt about this, ask yourself how your driving behavior might differ in two situations: In the first situation, you are driving down a deserted highway during the middle of the day; in the second situation, you are being followed by a police car down the same deserted highway (Figure 1).

It should be pointed out that naturalistic observation is not limited to research involving humans. Indeed, some of the best-known examples of naturalistic observation involve researchers going into the field to observe various kinds of animals in their own environments. As with human studies, the researchers maintain their distance and avoid interfering with the animal subjects so as not to influence their natural behaviors. Scientists have used this technique to study social hierarchies and interactions among animals ranging from ground squirrels to gorillas. The information provided by these studies is invaluable in understanding how those animals organize socially and communicate with one another. The anthropologist Jane Goodall,(image below) for example, spent nearly five decades observing the behavior of chimpanzees in Africa. As an illustration of the types of concerns that a researcher might encounter in naturalistic observation, some scientists criticized Goodall for giving the chimps names instead of referring to them by numbers—using names was thought to undermine the emotional detachment required for the objectivity of the study (McKie, 2010).

The greatest benefit of naturalistic observation is the validity, or accuracy, of information collected unobtrusively in a natural setting. Having individuals behave as they normally would in a given situation means that we have a higher degree of ecological validity, or realism, than we might achieve with other research approaches. Therefore, our ability to  generalize  the findings of the research to real-world situations is enhanced. If done correctly, we need not worry about people or animals modifying their behavior simply because they are being observed. Sometimes, people may assume that reality programs give us a glimpse into authentic human behavior. However, the principle of inconspicuous observation is violated as reality stars are followed by camera crews and are interviewed on camera for personal confessionals. Given that environment, we must doubt how natural and realistic their behaviors are.

The major downside of naturalistic observation is that they are often difficult to set up and control. In our restroom study, what if you stood in the restroom all day prepared to record people’s hand washing behavior and no one came in? Or, what if you have been closely observing a troop of gorillas for weeks only to find that they migrated to a new place while you were sleeping in your tent? The benefit of realistic data comes at a cost. As a researcher you have no control of when (or if) you have behavior to observe. In addition, this type of observational research often requires significant investments of time, money, and a good dose of luck.

Sometimes studies involve structured observation . In these cases, people are observed while engaging in set, specific tasks. An excellent example of structured observation comes from the Strange Situation by Mary Ainsworth (you will read more about this later). The Strange Situation is a procedure used to evaluate attachment styles that exist between an infant and caregiver. In this scenario, caregivers bring their infants into a room filled with toys. The Strange Situation involves a number of phases, including a stranger coming into the room, the caregiver leaving the room, and the caregiver’s return to the room. The infant’s behavior is closely monitored at each phase, but it is the behavior of the infant upon being reunited with the caregiver that is most telling in terms of characterizing the infant’s attachment style with the caregiver.

Another potential problem in observational research is  observer bias . Generally, people who act as observers are closely involved in the research project and may unconsciously skew their observations to fit their research goals or expectations. To protect against this type of bias, researchers should have clear criteria established for the types of behaviors recorded and how those behaviors should be classified. In addition, researchers often compare observations of the same event by multiple observers, in order to test  inter-rater reliability : a measure of reliability that assesses the consistency of observations by different observers. [6]

Survey Methodology

Surveys are familiar to most people because they are so widely used. Surveys enhance accessibility to subjects because they can be conducted in person, over the phone, through the mail, or online. A survey involves asking a standard set of questions to a group of subjects. In a highly structured survey, subjects are forced to choose from a response set such as “strongly disagree, disagree, undecided, agree, strongly agree”; or “0, 1-5, 6-10, etc.” Surveys are commonly used by sociologists, marketing researchers, political scientists, therapists, and others to gather information on several variables in a relatively short period of time. Surveys typically yield surface information on a wide variety of factors but may not allow for in-depth understanding of human behavior. Of course, surveys can be designed in a number of ways. They may include forced choice questions and semi-structured questions in which the researcher allows the respondent to describe or give details about certain events. One of the most difficult aspects of designing a good survey is wording questions in an unbiased way and asking the right questions so that respondents can give a clear response rather that choosing “undecided” each time. Knowing that 30% of respondents are undecided is of little use! So, a lot of time and effort should be placed on the construction of survey items. One of the benefits of having forced choice items is that each response is coded so that the results can be quickly entered and analyzed using statistical software. Analysis takes much longer when respondents give lengthy responses that must be analyzed in a different way. Surveys are useful in examining stated values, attitudes, opinions, and reporting on practices. However, they are based on self-report or what people say they do rather than on observation and this can limit accuracy. [7]

The Survey Below Asks Questions Regarding School Reform [8]

Rather than surveying participants, they can be interviewed which means they are directly questioned by a researcher. Interviewing participants on their behaviors or beliefs can solve the problem of misinterpreting the questions posed on surveys. The examiner can explain the questions and further probe responses for greater clarity and understanding. Although this can yield more accurate results, interviews take longer and are more expensive to administer than surveys. Participants can also demonstrate social desirability, which will affect the accuracy of the responses.

Psychophysiological Assessment

Researchers may also record psychophysiological data , such as measures of heart rate, hormone levels, or brain activity to help explain development. These measures may be recorded by themselves or in combination with behavioral data to better understand the bidirectional relations between biology and behavior. Special equipment has been developed to allow researchers to record the brain activity of infants and children. One manner of understanding associations between brain development and behavioral advances is through the recording of event-related potentials (ERPs). ERPs are recorded by fitting a research participant with a stretchy cap that contains many small sensors or electrodes . These electrodes record tiny electrical currents on the scalp of the participant in response to the presentation of stimuli, such as a picture or a sound.

The use of ERPs has provided important insight as to how infants and children understand the world around them. Webb, Dawson, Bernier, and Panagiotides (2006) examined face and object processing in children with autism spectrum disorders, those with developmental delays, and those who were typically developing. The children wore electrode caps and had their brain activity recorded as they watched still photographs of faces of their mother or of a stranger, and objects, including those that were familiar or unfamiliar to them. The researchers examined differences in face and object processing by group by observing a component of the brainwaves. Findings suggest that children with autism are in some way processing faces differently than typically developing children and those with more general developmental delays.

Secondary/Content Analysis or Archival Research

Secondary/content analysis or archival research involves analyzing information that has already been collected or examining documents or media to uncover attitudes, practices or preferences. There are many data sets available to those who wish to conduct this type of research. For example, the U. S. Census Data is available and widely used to look at trends and changes taking place in the United States. The researcher conducting secondary analysis does not have to recruit subjects but does need to know the quality of the information collected in the original study.

Correlational Research

In contrast to descriptive research, which is designed primarily to provide static pictures, correlational research involves the measurement of two or more variables (a variable is anything that can change in value) and an assessment of the relationship between or among those variables. For instance, the variables of height and weight are systematically related (correlated) because taller people generally weigh more than shorter people.

The Pearson Correlation Coefficient, symbolized by the letter r, is the most common statistical measure of the strength of linear relationships among variables. The value of the correlation coefficient ranges from r= –1.00 to r = 1.00. The strength of the linear relationship is indexed by the distance of the correlation coefficient from zero (its absolute value). For instance, r = –.54 is a stronger relationship than r= .30, and r = .72 is a stronger relationship than r = –.57. The direction of the linear relationship is indicated by the sign of the correlation coefficient . Positive values of r (such as r = .54 or r = .67) indicate that the relationship is positive (i.e., the pattern of the dots on the scatter plot runs from the lower left to the upper right), whereas negative values of r (such as r = –.30 or r = –.72) indicate negative relationships (i.e., the dots run from the upper left to the lower right).

Examples of positive and negative correlational data presented as scatterplots

When the straight line indicates that individuals who have high values for one variable also tend to have high values for the other variable, as in part (a) above, the relationship is said to be a positive correlation . Examples of positive correlations include those between education and income, and between age and mathematical abilities in children. In each case people who score higher on one of the variables also tend to score higher on the other variable. Negative correlations , in contrast, as shown in part (b) above, occur when high values for one variable tend to be associated with low values for the other variable. Examples of negative correlations include those between the age of a child and the number of diapers the child uses, and between practice and errors made on a learning task. In these cases, people who score higher on one of the variables tend to score lower on the other variable. [9]

An example of how a scatterplot might look in the case where a study finds that kindergarten and elementary school children who were better at rhymes and hearing the sounds of individual letters before they started to read later learn to read words more quickly than children who were not as good with making an distinguishing elementary sounds of language can be found below.

Scatterplot Between Speed of Learning to Read and Ability to Make and Hear Language-Related Sounds

The above scatter plots shows that the relationship between “Speed of Learning to Read” and the “Ability to Make and Hear Language-Related Sounds is “positive” and “strong. “ [10]

An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. In other words, CORRELATION IS NOT CAUSATION .  Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children. He has collected, from a sample of fourth-grade children, a measure of how much violent television each child views during the week, as well as a measure of how aggressively each child plays. The researcher discovers a positive correlation between the two measured variables. Although this positive correlation appears to support the hypothesis, it cannot be taken to indicate that viewing violent television causes aggressive behavior or aggressive behavior causes one to view violent television.  Another possible explanation for the observed correlation is that it has been produced by the presence of a third variable.

A third or extraneous variable is a variable that is not part of the research hypothesis but produces the observed correlation between them. In our example a potential third variable is the discipline style of the children’s parents. Parents who use a harsh and punitive discipline style may produce children who both like to watch violent television and who behave aggressively in comparison to children whose parents use less harsh discipline.

For this reason, we are left with the basic limitation of correlational research: Correlation does not demonstrate causation! It is important that when you read about correlational research projects, you keep in mind the possibility of third variables.

Strengths and limitations of Correlational Research

Correlational research can be used when experimental research is not possible because the variables either cannot be manipulated, or it would be unethical to use an experiment. Correlational designs also have the advantage of allowing the researcher to study behavior as it occurs in everyday life. We can also use correlational designs to make predictions. For instance, we can predict from the scores on a battery of tests the success of job trainees during a training session. However, we cannot use such correlational information to determine whether one variable caused another variable. For that, researchers rely on an experiment.

Experimental Research

In order to conduct an experiment, a researcher must have a specific hypothesis to be tested. As you’ve learned, hypotheses can be formulated either through direct observation of the real world or after careful review of previous research. For example, if you think that children should not be allowed to watch violent programming on television because doing so would cause them to behave more violently, then you have basically formulated a hypothesis—namely, that watching violent television programs causes children to behave more violently. How might you have arrived at this particular hypothesis? You may have younger relatives who watch cartoons featuring characters using martial arts to save the world from evildoers, with an impressive array of punching, kicking, and defensive postures. You notice that after watching these programs for a while, your young relatives mimic the fighting behavior of the characters portrayed in the cartoon.

These sorts of personal observations are what often lead us to formulate a specific hypothesis, but we cannot use limited personal observations and anecdotal evidence to rigorously test our hypothesis. Instead, to find out if real-world data supports our hypothesis, we have to conduct an experiment. [11]

Three conditions must be met to establish cause and effect. Experimental designs are useful in meeting these conditions.

• The independent variable and the dependent variable must be related. In other words, when one is altered, the other changes in response. (The independent variable is something altered or introduced by the researcher. The dependent variable is the outcome that is measured, or the factor affected by the introduction of the independent variable. For example, if we are looking at the impact of different levels of intervention on reading scores, the independent variable would be the level of intervention and the dependent variable would be the reading scores.)
• The cause must come before the effect. Experiments involve measuring subjects on the dependent variable before exposing them to the independent variable (establishing a baseline). So, we would measure the subjects’ level of reading before introducing the intervention program and then again after the intervention program to see if there has been a change in reading scores. (Observational and survey research does not always allow us to look at the timing of these events, which makes understanding causality problematic with these designs.)
• The cause must be isolated. The researcher must ensure that no outside, perhaps unknown or confounding variables are causing the effect we see. The experimental design helps make this possible. In an experiment, we would make sure that our subjects did not receive any intervention at home or at an after-school program. Otherwise these additional interventions might influence reading scores. [12]

Designing an Experiment

The most basic experimental design involves two groups: the experimental group and the control group . The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested (in this case, violent TV images)—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to experimental manipulation rather than chance.

In our example of how violent television programming might affect violent behavior in children, we have the experimental group view violent television programming for a specified time and then measure their violent behavior. We measure the violent behavior in our control group after they watch nonviolent television programming for the same amount of time. It is important for the control group to be treated similarly to the experimental group, with the exception that the control group does not receive the experimental manipulation. Therefore, we have the control group watch non-violent television programming for the same amount of time as the experimental group.

We also need to precisely define, or operationalize, what is considered violent and nonviolent. An  operational definition  is a description of how we will measure our variables, and it is important in allowing others understand exactly how and what a researcher measures in a particular experiment. In operationalizing violent behavior, we might choose to count only physical acts like kicking or punching as instances of this behavior, or we also may choose to include angry verbal exchanges. Whatever we determine, it is important that we operationalize violent behavior in such a way that anyone who hears about our study for the first time knows exactly what we mean by violence. This aids peoples’ ability to interpret our data as well as their capacity to repeat our experiment should they choose to do so.

Test Your Knowledge of a Good Operational Definition:  Below you will find 5 suggested operational definitions.  For each statement, determine whether or not the statement either provides a good example of an operational definition (True), or does not provide a good example of an operational definition (False).

Once we have operationalized what is considered violent television programming and what is considered violent behavior from our experiment participants, we need to establish how we will run our experiment. In this case, we might have participants watch a 30-minute television program (either violent or nonviolent, depending on their group membership) before sending them out to a playground for an hour where their behavior is observed and the number and type of violent acts is recorded.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias.  Experimenter bias  refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was in which group, it might influence how much attention they paid to each child’s behavior as well as how they interpreted that behavior. By being blind to which child is in which group, we protect against those biases. This situation is a  single-blind study , meaning that one of the groups (participants) are unaware as to which group they are in (experiment or control group) while the researcher who developed the experiment knows which participants are in each group.

In a  double-blind study , both the researchers and the participants are blind to group assignments. Why would a researcher want to run a study where no one knows who is in which group? Because by doing so, we can control for both experimenter and participant expectations. If you are familiar with the phrase placebo effect, you already have some idea as to why this is an important consideration. The  placebo effect  occurs when people’s expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

The placebo effect is commonly described in terms of testing the effectiveness of a new medication. Imagine that you work in a pharmaceutical company, and you think you have a new drug that is effective in treating depression. To demonstrate that your medication is effective, you run an experiment with two groups: The experimental group receives the medication, and the control group does not. But you don’t want participants to know whether they received the drug or not.

Why is that? Imagine that you are a participant in this study, and you have just taken a pill that you think will improve your mood. Because you expect the pill to have an effect, you might feel better simply because you took the pill and not because of any drug actually contained in the pill—this is the placebo effect.

To make sure that any effects on mood are due to the drug and not due to expectations, the control group receives a placebo (in this case a sugar pill). Now everyone gets a pill, and once again neither the researcher nor the experimental participants know who got the drug and who got the sugar pill. Any differences in mood between the experimental and control groups can now be attributed to the drug itself rather than to experimenter bias or participant expectations. [13]

Independent and Dependent Variables

In a research experiment, we strive to study whether changes in one thing cause changes in another. To achieve this, we must pay attention to two important variables, or things that can be changed, in any experimental study: the independent variable and the dependent variable . An independent variable is manipulated or controlled by the experimenter. In a well-designed experimental study, the independent variable is the only important difference between the experimental and control groups. In our example of how violent television programs affect children’s display of violent behavior, the independent variable is the type of program—violent or nonviolent—viewed by participants in the study (Figure 3). A dependent variable is what the researcher measures to see how much effect the independent variable had. In our example, the dependent variable is the number of violent acts displayed by the experimental participants.

The Influence of the Independent Variable on the Dependent Variable

In an experiment, manipulations of the independent variable are expected to result in changes in the dependent variable . (credit “automatic weapon”: modifications of work by Daniel Oines: credit “toy gun”: modifications of work by Emran Kassim)

We expect that the dependent variable will change as a function of the independent variable. In other words, the dependent variable  depends  on the independent variable. A good way to think about the relationship between the independent and dependent variables is with this question: What effect does the independent variable have on the dependent variable? Returning to our example, what effect does watching a half hour of violent television programming or nonviolent television programming have on the number of incidents of physical aggression displayed on the playground?

Selecting and Assigning Experimental Participants

Now that our study is designed, we need to obtain a sample of individuals to include in our experiment. Our study involves human participants so we need to determine who to include.  Participants  are the subjects of psychological research, and as the name implies, individuals who are involved in psychological research actively participate in the process. Often, psychological research projects rely on college students to serve as participants. In fact, the vast majority of research in psychology subfields has historically involved students as research participants (Sears, 1986; Arnett, 2008). But are college students truly representative of the general population? College students tend to be younger, more educated, more liberal, and less diverse than the general population. Although using students as test subjects is an accepted practice, relying on such a limited pool of research participants can be problematic because it is difficult to generalize findings to the larger population.

Our hypothetical experiment involves children, and we must first generate a sample of child participants. Samples are used because populations are usually too large to reasonably involve every member in our particular experiment. If possible, we should use a  random sample  (there are other types of samples, but for the purposes of this section, we will focus on random samples). A random sample is a subset of a larger population in which every member of the population has an equal chance of being selected. Random samples are preferred because if the sample is large enough, we can be reasonably sure that the participating individuals are representative of the larger population. This means that the percentages of characteristics in the sample—sex, ethnicity, socioeconomic level, and any other characteristics that might affect the results—are close to those percentages in the larger population.

In our example, let’s say we decide our population of interest is fourth graders. But all fourth graders is a very large population, so we need to be more specific; instead we might say our population of interest is all fourth graders in a particular city. We should include students from various income brackets, family situations, races, ethnicities, religions, and geographic areas of town. With this more manageable population, we can work with the local schools to randomly select around 200 fourth graders who we want to participate in our experiment.

In summary, because we cannot test all of the fourth graders in a city, we want to find a group of about 200 that reflects the composition of that city. With a representative group, we can generalize our findings to the larger population without fear of our sample being biased in some way.

Now that we have a sample, the next step of the experimental process is to split the participants into experimental and control groups through random assignment. With  random assignment , all participants have an equal chance of being assigned to either group. There is statistical software that will randomly assign each of the fourth graders in the sample to either the experimental or the control group.

Random assignment is critical for sound experimental design. With sufficiently large samples, random assignment makes it unlikely that there are systematic differences between the groups. So, for instance, it would be very unlikely that we would get one group composed entirely of males, a given ethnic identity, or a given religious ideology. This is important because if the groups were systematically different before the experiment began, we would not know the origin of any differences we find between the groups: Were the differences preexisting, or were they caused by manipulation of the independent variable? Random assignment allows us to assume that any differences observed between experimental and control groups result from the manipulation of the independent variable. [14]

Despite the advantage of determining causation, experiments do have limitations. One is that they are often conducted in laboratory situations rather than in the everyday lives of people. Therefore, we do not know whether results that we find in a laboratory setting will necessarily hold up in everyday life. Second, and more important, is that some of the most interesting and key social variables cannot be experimentally manipulated because of ethical concerns. If we want to study the influence of abuse on children’s development of depression, these relationships must be assessed using correlational designs because it is simply not ethical to experimentally manipulate these variables. Characteristics of descriptive, correlational, and experimental research designs can be found in the following table. [15] , [16]

Table describing the type of research design with corresponding Goal, Advantages, and Disadvantages.

Developmental Research Designs

While research methods are tools that are used to collect information, research design is the strategy or blueprint for deciding how to collect and analyze information. Research design dictates which research methods are used and how. When we are trying to describe development and change, the research designs become especially important because we are interested in what changes and what stays the same with age. [19]   Developmental researchers typically use one of three types of developmental research design, either cross-sectional , longitudinal , or cross-sequential/sequential .

Cross-Sectional, Longitudinal and Cross Sequential/Sequential Research Designs

Cross sectional research designs.

Cross-sectional research compares samples that represent a cross-section of the population who vary in age. Participants might be asked to complete a survey or take a test of some physical or cognitive skill. The attitudes or skill levels based on age are compared. In cross-sectional research, respondents are measured only once, and consequently this method is not expensive or time consuming. In addition, because participants are only tested at one point in time, practice effects are not an issue as children do not have the opportunity to become better at the task over time. There is also no need to keep in contact with, or follow-up with, participants over time.  The table [17] below shows that the study included a group of 2-year-olds, a group of 6-year-olds and a group of 8-year-olds.

Cohort Group Participants of a Cross-Sectional Design

However, cross-sectional research does not allow the researcher to look at the impact of having been born in a certain time-period, which is known as the cohort effect . For example, those born during the depression have very different views about and experiences with the internet than those born in the last twenty years. Different attitudes about the Internet, for example, might not be due to a person’s biological age as much as their life experiences as members of a cohort. [18]

Longitudinal Research Designs

Longitudinal research involves studying a group of people who are the same age and measuring them repeatedly over a period-of-time. This type of design allows researchers to study individual differences in development. Longitudinal studies may be conducted over the short term, such as a span of months, or over much longer durations including years or decades. For these reasons, longitudinal research designs are optimal for studying stability and change over time.

Cohort Group Participants of a Longitudinal Design

Problems with longitudinal research include being very time consuming and expensive. Researchers must maintain continued contact with participants over time, and these studies necessitate that scientists have funding to conduct their work over extended durations. An additional risk is attrition. Attrition occurs when participants fail to complete all portions of a study. Participants may move, change their phone numbers, or simply become disinterested in participating over time. Researchers should account for the possibility of attrition by enrolling a larger sample into their study initially, as some participants will likely drop out over time. Even with a large sample size, the experimenter never knows if there was something different about the individuals who dropped out versus those that remained in the study.

The results from longitudinal studies may also be impacted by repeated assessments. Consider how well you would do on a math test if you were given the exact same exam every day for a week. Your performance would likely improve over time not necessarily because you developed better math abilities, but because you were continuously practicing the same math problems. This phenomenon is known as a practice effect. Practice effects occur when participants become better at a task over time because they have done it again and again; not due to natural psychological development. [19]

Cross-Sequential/Sequential Designs

Cross-sequential research includes elements of both longitudinal and cross-sectional research designs. Like longitudinal designs, sequential research features participants who are followed over time; like cross-sectional designs, sequential work includes participants of different ages. This research design is also distinct from those that have been discussed previously in that individuals of different ages are enrolled into a study at various points in time to examine age-related changes, development within the same individuals as they age, and account for the possibility of cohort effects. [20]

Cohort Group Participants of a Cross-Sequential Design

For example, in a study with a sequential design, a researcher might enroll three separate groups of children (Groups A, B, and C). Children in Group A would be enrolled when they are 2 years old and would be tested again when they are 4 and 6 years old. This is similar in design to the longitudinal study described previously. Children in Group B would also be enrolled when they are 2 years old, but this would occur two years later when Group A is now 4 years old. Finally, children in Group C would be enrolled when they are 2 years old and Group A is now 6 and Group B is now 4. At this time, the children would represent a cross-sectional design (2, 4, and 6 years of age). Further, along the diagonal children of the same age can be compared to determine if cohort effects are evident. Sequential designs are appealing because they allow researchers to learn a lot about development in a relatively short amount of time.

Because they include elements of longitudinal and cross-sectional designs, sequential research has many of the same strengths and limitations as these other approaches. For example, sequential work may require less time and effort than longitudinal research, but more time and effort than cross-sectional research. Although practice effects may be an issue if participants are asked to complete the same tasks or assessments over time, attrition may be less problematic than what is commonly experienced in longitudinal research since participants may not have to remain involved in the study for such a long period-of-time. [21]   The table that follows summarizes the advantages and disadvantages of developmental research designs.

Advantages and Disadvantages of Developmental Research Designs [27]

Preferential Looking and Habituation

Conducting psychological experiments that involve infant participants can be difficult.  Infants may fall asleep or cry during procedures, and typically do not follow instructions well.  The most difficult aspect of working with infants is their lack of language abilities.  In other words, infants can’t tell you what they think, believe, or feel like adults can.  However, infant visual capabilities while not as developed as older children or adults can be used to provide researchers with insights into their cognitive abilities.

Preferential Looking

In 1961 Robert L. Fantz introduced the visual preference paradigm .  The technique was simple, show infants two different stimuli paired alongside each other and measure how long the infant would look at either stimulus.  Fantz concluded that the stimulus the infants looked longer at was the preferred stimulus.  As he continued his technique, he began to find similar preference patterns among infants.  For example, Fantz showed that from 2 months of age, infants preferred complex images like bulls-eyes over plain white or black circles.  One of his more interesting findings is that newborns and infants prefer faces and face-like patterns over non-face-like patterns.  This finding led Fantz to hypothesize that this preference was an innate ability that might serve to enhance survival of the newborn and infant.

Fantz’s Looking Chamber

The preferential looking technique can be used to test infant visual acuity.  In this case infants are shown several presentations of different stimuli consisting of black and white stripes of varying widths alongside a control stimulus (a uniform grey disc).  When the looking time between the two stimuli is approximately 50% for either stimulus the infant’s visual acuity limit has been reached.

Finally, the concept behind the preferential looking technique have been adapted for use in the study of audition.  The head-turn preference procedure (HPP) or preferential listening paradigm is used to explore infants’ ability to discriminate between auditory stimuli.

Infant Preferential Looking

Habituation

Fantz was one of the first researchers to make use of the habituation technique (although he did not refer to the technique as “habituation) to study human infant perceptual and cognitive abilities.

In habituation studies, infants are presented with a stimulus such as a photograph of a face over several trials until they become bored with it. Typically, when infants become bored, they will look away from the picture. Once the infant has been habituated, or bored, a new or test stimulus is then paired with the original stimulus.  Therefore, if the infant is shown a new picture–such as a photograph of a different face paired with the original picture, their interest will return, and they will look longer at the new picture. This is a phenomenon known as dishabituation . Habituation procedures work because infants generally look longer at novel stimuli relative to items that are familiar to them. This research technique takes advantage of involuntary or obligatory responses because infants are constantly looking around and observing their environments; they do not have to be taught to engage with the world in this way. [23]

Types of Habituation Protocols

Fixed trial habituation protocols and the infant-controlled procedure.

The simplest habituation protocols are fixed trial (FT) procedures , which involve administering a set of discrete, repetitive stimulus presentations to an infant; each trial has a fixed duration, and a fixed inter-trial interval. For example, one might present 8 trials of a checkerboard to an infant, each lasting 10 s with a 10 s inter-trial interval (e.g., Colombo et al., 1997). In simple FT protocols, the presentations are in no way linked to, or contingent upon, the infant’s behavior or visual attention; the infant is free to look or not look at the stimulus, and the procedure continues. There are a number of distinct advantages to running FT procedures: they are easy to automate, easy to conduct, and they yield data that are simple, uniform for each subject, and easy to analyze. The drawback of FT protocols, however, is that individual infants may habituate at different rates. To the degree that habituation rate reflects stimulus encoding (a central tenet of the comparator model), this implies that at the end of the FT protocol, infants may be at very different levels of processing. For instance, in the example described above (8 trials at 10 seconds each), infants might have looked for as much as 80 seconds and as little as 0 seconds. If one is interested in individual differences in infant processing, this may well be desirable (presuming that the infant has, in fact, looked at the stimulus), as it becomes analogous to a speeded cognitive task, where subjects are given a limited amount of time or exposure to an item before being administered a probe. However, if the aim of the protocol is to demonstrate a generic infant ability or skill, individual and developmental differences in visual behavior may obscure group effects that one is seeking to establish. [24]

This problem is addressed by the development of the infant-controlled procedure (ICP; Horowitz et al., 1972). There are two major differences between this procedure and the fixed trial protocol. The first is that the infant is administered repetitive stimulus presentations, but the beginning and end of the trial is contingent upon the infant’s looking. That is, the trial is not considered to start until the infant has looked at the stimulus, and it is terminated when the infant looks away.

Second, the trials continue until the infant has reduced their looking to some criterion. This criterion may be absolute (e.g., the sessions may end when the infant looks for a total of, say, no more than 3 seconds), but more often the criterion is relative to the infant’s initial level of looking. For example, the infant may be required to show a decline to a particular percentage (typically 50%) of their initial or longest levels.  For example, an experimenter determines the average of the first three trials of looking and continues until the last three trials of looking average 50% or below the average of the first three trials.  In this case, the trials can last anywhere from six trials and longer and will continue until the criteria specified has been reached.  It should be noted that the use of a relative criterion makes theoretical sense from the point of view of the comparator model; if the initial size of the OR (i.e., the length of the look) represents the response when there is no internal representation of the stimulus, then using a constant percentage of decline as a criterion for habituation theoretically equates all of the subjects for the extent to which the external stimulus is encoded. We note that this reasoning is based on a set of assumptions with regard to looking and the OR, but it is also reasonable to point out that the ICP works extremely well in practice.

There are several other issues to consider with respect to the ICP, however. The first one is that this procedure is more difficult to design and implement than the FT protocol. Because criteria are computed, set, and typically reset several times within a session (based on the looks that the infant makes to the stimulus), it is difficult to conduct this without the aid of a microcomputer and custom programming.

Second, there are many decisions to be made about the parameters of the habituation protocol, for which there are neither consensual standards nor empirical evidence to guide the investigator. For example, instead of using the average of the first three trials of looking as a comparison, a researcher may decide to use the average of the first two looking trials as the baseline for comparison.  These decisions can complicate the programming for the administration of the task. Group habituation curves will mislead many novice investigators into thinking that the first look of a habituation sequence is always the longest one. In fact, however, this occurs only about 60% of the time (Colombo & Mitchell, 1990). Thus, it is common to encounter long looks quite late in the habituation session, and if the habituation criterion is rigidly set by the length of the initial looks, infants will continue on in the session longer than necessary or may fail to attain the habituation criterion at all. In response to this, many investigators choose to allow the habituation criterion to “float,” or to be reset when longer looks occur later (i.e., beyond the first or second look) in the habituation sequence. In addition, the number of looks on which the criterion is based can vary; it may be based on the longest look, or the average of the two longest looks, or so forth. Similar issues must be faced when choosing how many criterion looks must be elicited to consider the infant to have habituated; here, the standard used by most investigators is two consecutive looks at or below criterion, but there is no empirical justification for this. accepted standard.

Third, the ICP dictates that the coding of looks must be done online, because the criterion for habituation is based on the duration of looks that have been observed earlier in the session. This has some implications for the reliability of online coding, but the coding of looks using the corneal reflection technique (or other less restrictive judgment criteria) tends to be quite easy and reliable. However, because the individual “look” now serves as the primary datum within the session, one must decide what constitutes a “look.” It is possible to place no constraints on the definition of a look; that is, to count any look to the stimulus as valid for purposes of setting or reaching the habituation criterion. However, one finds quickly that this may yield sequences of brief looks that result in very brief stimulus presentations that interfere with encoding; in addition, such looks may make it difficult to attain the habituation criterion, and have lower reliability (Colombo & Horowitz, 1985). In response, most investigators constrain the definition of looks in the ICP; looks must be of some minimum length (usually 1 or 2 sec) to be counted as valid, and be terminated by some minimum (again, 1 or 2 sec) look away from the stimulus. One of the few empirical evaluations of these procedural parameters, Colombo and Horowitz (1985) found 1 sec to be optimal for both the minimum look length and for the interval to characterize look termination, although this evidence has engendered little/no adoption of these standards, and no research has been conducted to determine whether different parameters might be appropriate for different aged infants.

Finally, it should be noted that like all criterion-based learning paradigms, the ICP will yield data sets that are not uniform in length for all participants; one infant may attain the habituation criterion in 5 looks, while another may take 25 looks to attain the criterion. As a result, the data structures for such files are not readily amenable to conventional forms of analysis and require considerable forethought in arranging. [25]

Conducting Ethical Research

As a student of psychological science, you may already know that Institutional Review Boards (IRBs) review and approve all research projects that are conducted at universities, hospitals, and other institutions. An IRB is typically a panel of experts who read and evaluate proposals for research. IRB members want to ensure that the proposed research will be carried out ethically and that the potential benefits of the research outweigh the risks and harm for participants. What you may not know though, is that the IRB considers some groups of participants to be more vulnerable or at-risk than others. Whereas university students are generally not viewed as vulnerable or at-risk, infants and young children commonly fall into this category. What makes infants and young children more vulnerable during research than young adults? One reason infants and young children are perceived as being at increased risk is due to their limited cognitive capabilities, which makes them unable to state their willingness to participate in research or tell researchers when they would like to drop out of a study. For these reasons, infants and young children require special accommodations as they participate in the research process.

When thinking about special accommodations in developmental research, consider the informed consent process. If you have ever participated in psychological research, you may know through your own experience that adults commonly sign an informed consent statement (a contract stating that they agree to participate in research) after learning about a study. As part of this process, participants are informed of the procedures to be used in the research, along with any expected risks or benefits. Infants and young children cannot verbally indicate their willingness to participate, much less understand the balance of potential risks and benefits. As such, researchers are oftentimes required to obtain written informed consent from the parent or legal guardian of the child participant, an adult who is almost always present as the study is conducted. In fact, children are not asked to indicate whether they would like to be involved in a study at all (a process known as assent ) until they are approximately seven years old. Because infants and young children also cannot easily indicate if they would like to discontinue their participation in a study, researchers must be sensitive to changes in the state of the participant (determining whether a child is too tired or upset to continue) as well as to parent desires (in some cases, parents might want to discontinue their involvement in the research). As in adult studies, researchers must always strive to protect the rights and well-being of the minor participants and their parents when conducting developmental science. [26]

Decisions about whether research is ethical are made using established ethical codes developed by scientific organizations, such as the American Psychological Association, and federal governments. In the United States, the Department of Health and Human Services provides the guidelines for ethical standards in research. The following are the American Psychological Association code of ethics when using humans in research (APA, 2016).

• No Harm: The most direct ethical concern of the scientist is to prevent harm to the research participants.
• Informed Consent: Researchers must obtain informed consent, which explains as much as possible about the true nature of the study, particularly everything that might be expected to influence willingness to participate. Participants can withdraw their consent to participate at any point.
• Confidentiality: Researchers must also protect the privacy of the research participants’ responses by not using names or other information that could identify the participants.
• Deception: Deception occurs whenever research participants are not completely and fully informed about the nature of the research project before participating in it. Deception may occur when the researcher tells the participants that a study is about one thing when in fact it is about something else, or when participants are not told about the hypothesis.
• Debriefing: At the end of a study debriefing, which is a procedure designed to fully explain the purposes and procedures of the research and remove any harmful aftereffects of participation, must occur.

Description of Assignment

During your time at Manor, you will need to conduct a child case study. To do well, you will need to plan ahead and keep a schedule for observing the child. A case study at Manor typically includes the following components: 

• Three observations of the child: one qualitative, one quantitative, and one of your choice. 
• Three artifact collections and review: one qualitative, one quantitative, and one of your choice. 
• A Narrative

Within this tab, we will discuss how to complete all portions of the case study.  A copy of the rubric for the assignment is attached. 

• Case Study Rubric (Online)
• Case Study Rubric (Hybrid/F2F)

Qualitative and Quantitative Observation Tips

Remember your observation notes should provide the following detailed information about the child:

• child’s age,
• physical appearance,
• the setting, and
• any other important background information.

You should observe the child a minimum of 5 hours. Make sure you DO NOT use the child's real name in your observations. Always use a pseudo name for course assignments. 

You will use your observations to help write your narrative. When submitting your observations for the course please make sure they are typed so that they are legible for your instructor. This will help them provide feedback to you. 

Qualitative Observations

A qualitative observation is one in which you simply write down what you see using the anecdotal note format listed below. 

Quantitative Observations

A quantitative observation is one in which you will use some type of checklist to assess a child's skills. This can be a checklist that you create and/or one that you find on the web. A great choice of a checklist would be an Ounce Assessment and/or work sampling assessment depending on the age of the child. Below you will find some resources on finding checklists for this portion of the case study. If you are interested in using Ounce or Work Sampling, please see your program director for a copy. 

Remaining Objective 

For both qualitative and quantitative observations, you will only write down what your see and hear. Do not interpret your observation notes. Remain objective versus being subjective.

An example of an objective statement would be the following: "Johnny stacked three blocks vertically on top of a classroom table." or "When prompted by his teacher Johnny wrote his name but omitted the two N's in his name." 

An example of a subjective statement would be the following: "Johnny is happy because he was able to play with the block." or "Johnny omitted the two N's in his name on purpose."

Qualitative and Quantitative Artifact Collection and Review Tips

For this section, you will collect artifacts from and/or on the child during the time you observe the child. Here is a list of the different types of artifacts you might collect: 

Potential Qualitative Artifacts 

• Photos of a child completing a task, during free play, and/or outdoors. 
• Samples of Artwork 
• Samples of writing 
• Products of child-led activities 

Potential Quantitative Artifacts 

• Checklist 
• Rating Scales

Narrative Tips

The Narrative portion of your case study assignment should be written in APA style, double-spaced, and follow the format below:

• Introduction : Background information about the child (if any is known), setting, age, physical appearance, and other relevant details. There should be an overall feel for what this child and his/her family is like. Remember that the child’s neighborhood, school, community, etc all play a role in development, so make sure you accurately and fully describe this setting! --- 1 page
• Observations of Development :   The main body of your observations coupled with course material supporting whether or not the observed behavior was typical of the child’s age or not. Report behaviors and statements from both the child observation and from the parent/guardian interview— 1.5  pages
• Comment on Development: This is the portion of the paper where your professional analysis of your observations are shared. Based on your evidence, what can you generally state regarding the cognitive, social and emotional, and physical development of this child? Include both information from your observations and from your interview— 1.5 pages
• Conclusion: What are the relative strengths and weaknesses of the family, the child? What could this child benefit from? Make any final remarks regarding the child’s overall development in this section.— 1page
• Your Case Study Narrative should be a minimum of 5 pages.

Make sure to NOT to use the child’s real name in the Narrative Report. You should make reference to course material, information from your textbook, and class supplemental materials throughout the paper . 

Same rules apply in terms of writing in objective language and only using subjective minimally. REMEMBER to CHECK your grammar, spelling, and APA formatting before submitting to your instructor. It is imperative that you review the rubric of this assignment as well before completing it. 

Biggest Mistakes Students Make on this Assignment

Here is a list of the biggest mistakes that students make on this assignment: 

• Failing to start early . The case study assignment is one that you will submit in parts throughout the semester. It is important that you begin your observations on the case study before the first assignment is due. Waiting to the last minute will lead to a poor grade on this assignment, which historically has been the case for students who have completed this assignment. 
• Failing to utilize the rubrics. The rubrics provide students with guidelines on what components are necessary for the assignment. Often students will lose points because they simply read the descriptions of the assignment but did not pay attention to rubric portions of the assignment. 
• Failing to use APA formatting and proper grammar and spelling. It is imperative that you use spell check and/or other grammar checking software to ensure that your narrative is written well. Remember it must be in APA formatting so make sure that you review the tutorials available for you on our Lib Guide that will assess you in this area.

Introduction

Welcome to Child Growth and Development. This text is a presentation of how and why children grow, develop, and learn.

We will look at how we change physically over time from conception through adolescence. We examine cognitive change, or how our ability to think and remember changes over the first 20 years or so of life. And we will look at how our emotions, psychological state, and social relationships change throughout childhood and adolescence. 1

Principles of Development

There are several underlying principles of development to keep in mind:

• Development is lifelong and change is apparent across the lifespan (although this text ends with adolescence). And early experiences affect later development.
• Development is multidirectional. We show gains in some areas of development, while showing loss in other areas.
• Development is multidimensional. We change across three general domains/dimensions; physical, cognitive, and social and emotional.
• The physical domain includes changes in height and weight, changes in gross and fine motor skills, sensory capabilities, the nervous system, as well as the propensity for disease and illness.
• The cognitive domain encompasses the changes in intelligence, wisdom, perception, problem-solving, memory, and language.
• The social and emotional domain (also referred to as psychosocial) focuses on changes in emotion, self-perception, and interpersonal relationships with families, peers, and friends.

All three domains influence each other. It is also important to note that a change in one domain may cascade and prompt changes in the other domains.

• Development is characterized by plasticity, which is our ability to change and that many of our characteristics are malleable. Early experiences are important, but children are remarkably resilient (able to overcome adversity).
• Development is multicontextual. 2 We are influenced by both nature (genetics) and nurture (the environment) – when and where we live and our actions, beliefs, and values are a response to circumstances surrounding us.  The key here is to understand that behaviors, motivations, emotions, and choices are all part of a bigger picture. 3

Now let’s look at a framework for examining development.

Periods of Development

Think about what periods of development that you think a course on Child Development would address. How many stages are on your list? Perhaps you have three: infancy, childhood, and teenagers. Developmentalists (those that study development) break this part of the life span into these five stages as follows:

• Prenatal Development (conception through birth)
• Infancy and Toddlerhood (birth through two years)
• Early Childhood (3 to 5 years)
• Middle Childhood (6 to 11 years)
• Adolescence (12 years to adulthood)

This list reflects unique aspects of the various stages of childhood and adolescence that will be explored in this book. So while both an 8 month old and an 8 year old are considered children, they have very different motor abilities, social relationships, and cognitive skills. Their nutritional needs are different and their primary psychological concerns are also distinctive.

Prenatal Development

Conception occurs and development begins. All of the major structures of the body are forming and the health of the mother is of primary concern. Understanding nutrition, teratogens (or environmental factors that can lead to birth defects), and labor and delivery are primary concerns.

Figure 1.1 – A tiny embryo depicting some development of arms and legs, as well as facial features that are starting to show. 4

Infancy and Toddlerhood

The two years of life are ones of dramatic growth and change. A newborn, with a keen sense of hearing but very poor vision is transformed into a walking, talking toddler within a relatively short period of time. Caregivers are also transformed from someone who manages feeding and sleep schedules to a constantly moving guide and safety inspector for a mobile, energetic child.

Figure 1.2 – A swaddled newborn. 5

Early Childhood

Early childhood is also referred to as the preschool years and consists of the years which follow toddlerhood and precede formal schooling. As a three to five-year-old, the child is busy learning language, is gaining a sense of self and greater independence, and is beginning to learn the workings of the physical world. This knowledge does not come quickly, however, and preschoolers may initially have interesting conceptions of size, time, space and distance such as fearing that they may go down the drain if they sit at the front of the bathtub or by demonstrating how long something will take by holding out their two index fingers several inches apart. A toddler’s fierce determination to do something may give way to a four-year-old’s sense of guilt for action that brings the disapproval of others.

Figure 1.3 – Two young children playing in the Singapore Botanic Gardens 6

Middle Childhood

The ages of six through eleven comprise middle childhood and much of what children experience at this age is connected to their involvement in the early grades of school. Now the world becomes one of learning and testing new academic skills and by assessing one’s abilities and accomplishments by making comparisons between self and others. Schools compare students and make these comparisons public through team sports, test scores, and other forms of recognition. Growth rates slow down and children are able to refine their motor skills at this point in life. And children begin to learn about social relationships beyond the family through interaction with friends and fellow students.

Figure 1.4 – Two children running down the street in Carenage, Trinidad and Tobago 7

Adolescence

Adolescence is a period of dramatic physical change marked by an overall physical growth spurt and sexual maturation, known as puberty. It is also a time of cognitive change as the adolescent begins to think of new possibilities and to consider abstract concepts such as love, fear, and freedom. Ironically, adolescents have a sense of invincibility that puts them at greater risk of dying from accidents or contracting sexually transmitted infections that can have lifelong consequences. 8

Figure 1.5 – Two smiling teenage women. 9

There are some aspects of development that have been hotly debated. Let’s explore these.

Issues in Development

Nature and nurture.

Why are people the way they are? Are features such as height, weight, personality, being diabetic, etc. the result of heredity or environmental factors-or both? For decades, scholars have carried on the “nature/nurture” debate. For any particular feature, those on the side of Nature would argue that heredity plays the most important role in bringing about that feature. Those on the side of Nurture would argue that one’s environment is most significant in shaping the way we are. This debate continues in all aspects of human development, and most scholars agree that there is a constant interplay between the two forces. It is difficult to isolate the root of any single behavior as a result solely of nature or nurture.

Continuity versus Discontinuity

Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change? The answer to that question often depends on which developmental theorist you ask and what topic is being studied. The theories of Freud, Erikson, Piaget, and Kohlberg are called stage theories. Stage theories or discontinuous development assume that developmental change often occurs in distinct stages that are qualitatively different from each other, and in a set, universal sequence. At each stage of development, children and adults have different qualities and characteristics. Thus, stage theorists assume development is more discontinuous. Others, such as the behaviorists, Vygotsky, and information processing theorists, assume development is a more slow and gradual process known as continuous development. For instance, they would see the adult as not possessing new skills, but more advanced skills that were already present in some form in the child. Brain development and environmental experiences contribute to the acquisition of more developed skills.

Figure 1.6 – The graph to the left shows three stages in the continuous growth of a tree. The graph to the right shows four distinct stages of development in the life cycle of a ladybug. 10

Active versus Passive

How much do you play a role in your own developmental path? Are you at the whim of your genetic inheritance or the environment that surrounds you? Some theorists see humans as playing a much more active role in their own development. Piaget, for instance believed that children actively explore their world and construct new ways of thinking to explain the things they experience. In contrast, many behaviorists view humans as being more passive in the developmental process. 11

How do we know so much about how we grow, develop, and learn? Let’s look at how that data is gathered through research

Research Methods

An important part of learning any science is having a basic knowledge of the techniques used in gathering information. The hallmark of scientific investigation is that of following a set of procedures designed to keep questioning or skepticism alive while describing, explaining, or testing any phenomenon. Some people are hesitant to trust academicians or researchers because they always seem to change their story. That, however, is exactly what science is all about; it involves continuously renewing our understanding of the subjects in question and an ongoing investigation of how and why events occur. Science is a vehicle for going on a never-ending journey. In the area of development, we have seen changes in recommendations for nutrition, in explanations of psychological states as people age, and in parenting advice. So think of learning about human development as a lifelong endeavor.

Take a moment to write down two things that you know about childhood. Now, how do you know? Chances are you know these things based on your own history (experiential reality) or based on what others have told you or cultural ideas (agreement reality) (Seccombe and Warner, 2004). There are several problems with personal inquiry. Read the following sentence aloud:

Paris in the

Are you sure that is what it said? Read it again:

If you read it differently the second time (adding the second “the”) you just experienced one of the problems with personal inquiry; that is, the tendency to see what we believe. Our assumptions very often guide our perceptions, consequently, when we believe something, we tend to see it even if it is not there. This problem may just be a result of cognitive ‘blinders’ or it may be part of a more conscious attempt to support our own views. Confirmation bias is the tendency to look for evidence that we are right and in so doing, we ignore contradictory evidence. Popper suggests that the distinction between that which is scientific and that which is unscientific is that science is falsifiable; scientific inquiry involves attempts to reject or refute a theory or set of assumptions (Thornton, 2005). Theory that cannot be falsified is not scientific. And much of what we do in personal inquiry involves drawing conclusions based on what we have personally experienced or validating our own experience by discussing what we think is true with others who share the same views.

Science offers a more systematic way to make comparisons guard against bias.

Scientific Methods

One method of scientific investigation involves the following steps:

• Determining a research question
• Reviewing previous studies addressing the topic in question (known as a literature review)
• Determining a method of gathering information
• Conducting the study
• Interpreting results
• Drawing conclusions; stating limitations of the study and suggestions for future research
• Making your findings available to others (both to share information and to have your work scrutinized by others)

Your findings can then be used by others as they explore the area of interest and through this process a literature or knowledge base is established. This model of scientific investigation presents research as a linear process guided by a specific research question. And it typically involves quantifying or using statistics to understand and report what has been studied. Many academic journals publish reports on studies conducted in this manner.

Another model of research referred to as qualitative research may involve steps such as these:

• Begin with a broad area of interest
• Gain entrance into a group to be researched
• Gather field notes about the setting, the people, the structure, the activities or other areas of interest
• Ask open ended, broad “grand tour” types of questions when interviewing subjects
• Modify research questions as study continues
• Note patterns or consistencies
• Explore new areas deemed important by the people being observed
• Report findings

In this type of research, theoretical ideas are “grounded” in the experiences of the participants. The researcher is the student and the people in the setting are the teachers as they inform the researcher of their world (Glazer & Strauss, 1967). Researchers are to be aware of their own biases and assumptions, acknowledge them and bracket them in efforts to keep them from limiting accuracy in reporting. Sometimes qualitative studies are used initially to explore a topic and more quantitative studies are used to test or explain what was first described.

Let’s look more closely at some techniques, or research methods, used to describe, explain, or evaluate. Each of these designs has strengths and weaknesses and is sometimes used in combination with other designs within a single study.

Observational Studies

Observational studies involve watching and recording the actions of participants. This may take place in the natural setting, such as observing children at play at a park, or behind a one-way glass while children are at play in a laboratory playroom. The researcher may follow a checklist and record the frequency and duration of events (perhaps how many conflicts occur among 2-year-olds) or may observe and record as much as possible about an event (such as observing children in a classroom and capturing the details about the room design and what the children and teachers are doing and saying). In general, observational studies have the strength of allowing the researcher to see how people behave rather than relying on self-report. What people do and what they say they do are often very different. A major weakness of observational studies is that they do not allow the researcher to explain causal relationships. Yet, observational studies are useful and widely used when studying children. Children tend to change their behavior when they know they are being watched (known as the Hawthorne effect) and may not survey well.

Experiments

Experiments are designed to test hypotheses (or specific statements about the relationship between variables) in a controlled setting in efforts to explain how certain factors or events produce outcomes. A variable is anything that changes in value. Concepts are operationalized or transformed into variables in research, which means that the researcher must specify exactly what is going to be measured in the study.

Three conditions must be met in order to establish cause and effect. Experimental designs are useful in meeting these conditions.

The independent and dependent variables must be related. In other words, when one is altered, the other changes in response. (The independent variable is something altered or introduced by the researcher. The dependent variable is the outcome or the factor affected by the introduction of the independent variable. For example, if we are looking at the impact of exercise on stress levels, the independent variable would be exercise; the dependent variable would be stress.)

The cause must come before the effect. Experiments involve measuring subjects on the dependent variable before exposing them to the independent variable (establishing a baseline). So we would measure the subjects’ level of stress before introducing exercise and then again after the exercise to see if there has been a change in stress levels. (Observational and survey research does not always allow us to look at the timing of these events, which makes understanding causality problematic with these designs.)

The cause must be isolated. The researcher must ensure that no outside, perhaps unknown variables are actually causing the effect we see. The experimental design helps make this possible. In an experiment, we would make sure that our subjects’ diets were held constant throughout the exercise program. Otherwise, diet might really be creating the change in stress level rather than exercise.

A basic experimental design involves beginning with a sample (or subset of a population) and randomly assigning subjects to one of two groups: the experimental group or the control group. The experimental group is the group that is going to be exposed to an independent variable or condition the researcher is introducing as a potential cause of an event. The control group is going to be used for comparison and is going to have the same experience as the experimental group but will not be exposed to the independent variable. After exposing the experimental group to the independent variable, the two groups are measured again to see if a change has occurred. If so, we are in a better position to suggest that the independent variable caused the change in the dependent variable.

The major advantage of the experimental design is that of helping to establish cause and effect relationships. A disadvantage of this design is the difficulty of translating much of what happens in a laboratory setting into real life.

Case Studies

Case studies involve exploring a single case or situation in great detail. Information may be gathered with the use of observation, interviews, testing, or other methods to uncover as much as possible about a person or situation. Case studies are helpful when investigating unusual situations such as brain trauma or children reared in isolation. And they are often used by clinicians who conduct case studies as part of their normal practice when gathering information about a client or patient coming in for treatment. Case studies can be used to explore areas about which little is known and can provide rich detail about situations or conditions. However, the findings from case studies cannot be generalized or applied to larger populations; this is because cases are not randomly selected and no control group is used for comparison.

Figure 1.7 – Illustrated poster from a classroom describing a case study. 12

Surveys are familiar to most people because they are so widely used. Surveys enhance accessibility to subjects because they can be conducted in person, over the phone, through the mail, or online. A survey involves asking a standard set of questions to a group of subjects. In a highly structured survey, subjects are forced to choose from a response set such as “strongly disagree, disagree, undecided, agree, strongly agree”; or “0, 1-5, 6-10, etc.” This is known as Likert Scale . Surveys are commonly used by sociologists, marketing researchers, political scientists, therapists, and others to gather information on many independent and dependent variables in a relatively short period of time. Surveys typically yield surface information on a wide variety of factors, but may not allow for in-depth understanding of human behavior.

Of course, surveys can be designed in a number of ways. They may include forced choice questions and semi-structured questions in which the researcher allows the respondent to describe or give details about certain events. One of the most difficult aspects of designing a good survey is wording questions in an unbiased way and asking the right questions so that respondents can give a clear response rather than choosing “undecided” each time. Knowing that 30% of respondents are undecided is of little use! So a lot of time and effort should be placed on the construction of survey items. One of the benefits of having forced choice items is that each response is coded so that the results can be quickly entered and analyzed using statistical software. Analysis takes much longer when respondents give lengthy responses that must be analyzed in a different way. Surveys are useful in examining stated values, attitudes, opinions, and reporting on practices. However, they are based on self-report or what people say they do rather than on observation and this can limit accuracy.

Developmental Designs

Developmental designs are techniques used in developmental research (and other areas as well). These techniques try to examine how age, cohort, gender, and social class impact development.

Longitudinal Research

Longitudinal research involves beginning with a group of people who may be of the same age and background, and measuring them repeatedly over a long period of time. One of the benefits of this type of research is that people can be followed through time and be compared with them when they were younger.

Figure 1.8 – A longitudinal research design. 13

A problem with this type of research is that it is very expensive and subjects may drop out over time. The Perry Preschool Project which began in 1962 is an example of a longitudinal study that continues to provide data on children’s development.

Cross-sectional Research

Cross-sectional research involves beginning with a sample that represents a cross-section of the population. Respondents who vary in age, gender, ethnicity, and social class might be asked to complete a survey about television program preferences or attitudes toward the use of the Internet. The attitudes of males and females could then be compared, as could attitudes based on age. In cross-sectional research, respondents are measured only once.

Figure 1.9 – A cross-sectional research design. 14

This method is much less expensive than longitudinal research but does not allow the researcher to distinguish between the impact of age and the cohort effect. Different attitudes about the use of technology, for example, might not be altered by a person’s biological age as much as their life experiences as members of a cohort.

Sequential Research

Sequential research involves combining aspects of the previous two techniques; beginning with a cross-sectional sample and measuring them through time.

Figure 1.10 – A sequential research design. 15

This is the perfect model for looking at age, gender, social class, and ethnicity. But the drawbacks of high costs and attrition are here as well. 16

Table 1 .1 – Advantages and Disadvantages of Different Research Designs 17

Consent and Ethics in Research

Research should, as much as possible, be based on participants’ freely volunteered informed consent. For minors, this also requires consent from their legal guardians. This implies a responsibility to explain fully and meaningfully to both the child and their guardians what the research is about and how it will be disseminated. Participants and their legal guardians should be aware of the research purpose and procedures, their right to refuse to participate; the extent to which confidentiality will be maintained; the potential uses to which the data might be put; the foreseeable risks and expected benefits; and that participants have the right to discontinue at any time.

But consent alone does not absolve the responsibility of researchers to anticipate and guard against potential harmful consequences for participants. 18 It is critical that researchers protect all rights of the participants including confidentiality.

Child development is a fascinating field of study – but care must be taken to ensure that researchers use appropriate methods to examine infant and child behavior, use the correct experimental design to answer their questions, and be aware of the special challenges that are part-and-parcel of developmental research. Hopefully, this information helped you develop an understanding of these various issues and to be ready to think more critically about research questions that interest you. There are so many interesting questions that remain to be examined by future generations of developmental scientists – maybe you will make one of the next big discoveries! 19

Another really important framework to use when trying to understand children’s development are theories of development. Let’s explore what theories are and introduce you to some major theories in child development.

Developmental Theories

What is a theory.

Students sometimes feel intimidated by theory; even the phrase, “Now we are going to look at some theories…” is met with blank stares and other indications that the audience is now lost. But theories are valuable tools for understanding human behavior; in fact they are proposed explanations for the “how” and “whys” of development. Have you ever wondered, “Why is my 3 year old so inquisitive?” or “Why are some fifth graders rejected by their classmates?” Theories can help explain these and other occurrences. Developmental theories offer explanations about how we develop, why we change over time and the kinds of influences that impact development.

A theory guides and helps us interpret research findings as well. It provides the researcher with a blueprint or model to be used to help piece together various studies. Think of theories as guidelines much like directions that come with an appliance or other object that requires assembly. The instructions can help one piece together smaller parts more easily than if trial and error are used.

Theories can be developed using induction in which a number of single cases are observed and after patterns or similarities are noted, the theorist develops ideas based on these examples. Established theories are then tested through research; however, not all theories are equally suited to scientific investigation.  Some theories are difficult to test but are still useful in stimulating debate or providing concepts that have practical application. Keep in mind that theories are not facts; they are guidelines for investigation and practice, and they gain credibility through research that fails to disprove them. 20

Let’s take a look at some key theories in Child Development.

Sigmund Freud’s Psychosexual Theory

We begin with the often controversial figure, Sigmund Freud (1856-1939). Freud has been a very influential figure in the area of development; his view of development and psychopathology dominated the field of psychiatry until the growth of behaviorism in the 1950s. His assumptions that personality forms during the first few years of life and that the ways in which parents or other caregivers interact with children have a long-lasting impact on children’s emotional states have guided parents, educators, clinicians, and policy-makers for many years. We have only recently begun to recognize that early childhood experiences do not always result in certain personality traits or emotional states. There is a growing body of literature addressing resilience in children who come from harsh backgrounds and yet develop without damaging emotional scars (O’Grady and Metz, 1987). Freud has stimulated an enormous amount of research and generated many ideas. Agreeing with Freud’s theory in its entirety is hardly necessary for appreciating the contribution he has made to the field of development.

Figure 1.11 – Sigmund Freud. 21

Freud’s theory of self suggests that there are three parts of the self.

The id is the part of the self that is inborn. It responds to biological urges without pause and is guided by the principle of pleasure: if it feels good, it is the thing to do. A newborn is all id. The newborn cries when hungry, defecates when the urge strikes.

The ego develops through interaction with others and is guided by logic or the reality principle. It has the ability to delay gratification. It knows that urges have to be managed. It mediates between the id and superego using logic and reality to calm the other parts of the self.

The superego represents society’s demands for its members. It is guided by a sense of guilt. Values, morals, and the conscience are all part of the superego.

The personality is thought to develop in response to the child’s ability to learn to manage biological urges. Parenting is important here. If the parent is either overly punitive or lax, the child may not progress to the next stage. Here is a brief introduction to Freud’s stages.

Table 1. 2 – Sigmund Freud’s Psychosexual Theory

Strengths and Weaknesses of Freud’s Theory

Freud’s theory has been heavily criticized for several reasons. One is that it is very difficult to test scientifically. How can parenting in infancy be traced to personality in adulthood? Are there other variables that might better explain development? The theory is also considered to be sexist in suggesting that women who do not accept an inferior position in society are somehow psychologically flawed. Freud focuses on the darker side of human nature and suggests that much of what determines our actions is unknown to us. So why do we study Freud? As mentioned above, despite the criticisms, Freud’s assumptions about the importance of early childhood experiences in shaping our psychological selves have found their way into child development, education, and parenting practices. Freud’s theory has heuristic value in providing a framework from which to elaborate and modify subsequent theories of development. Many later theories, particularly behaviorism and humanism, were challenges to Freud’s views. 22

Erik Erikson’s Psychosocial Theory

Now, let’s turn to a less controversial theorist, Erik Erikson. Erikson (1902-1994) suggested that our relationships and society’s expectations motivate much of our behavior in his theory of psychosocial development. Erikson was a student of Freud’s but emphasized the importance of the ego, or conscious thought, in determining our actions. In other words, he believed that we are not driven by unconscious urges. We know what motivates us and we consciously think about how to achieve our goals. He is considered the father of developmental psychology because his model gives us a guideline for the entire life span and suggests certain primary psychological and social concerns throughout life.

Figure 1.12 – Erik Erikson. 23

Erikson expanded on his Freud’s by emphasizing the importance of culture in parenting practices and motivations and adding three stages of adult development (Erikson, 1950; 1968). He believed that we are aware of what motivates us throughout life and the ego has greater importance in guiding our actions than does the id. We make conscious choices in life and these choices focus on meeting certain social and cultural needs rather than purely biological ones. Humans are motivated, for instance, by the need to feel that the world is a trustworthy place, that we are capable individuals, that we can make a contribution to society, and that we have lived a meaningful life. These are all psychosocial problems.

Erikson divided the lifespan into eight stages. In each stage, we have a major psychosocial task to accomplish or crisis to overcome.  Erikson believed that our personality continues to take shape throughout our lifespan as we face these challenges in living. Here is a brief overview of the eight stages:

Table 1. 3 – Erik Erikson’s Psychosocial Theory

These eight stages form a foundation for discussions on emotional and social development during the life span. Keep in mind, however, that these stages or crises can occur more than once. For instance, a person may struggle with a lack of trust beyond infancy under certain circumstances. Erikson’s theory has been criticized for focusing so heavily on stages and assuming that the completion of one stage is prerequisite for the next crisis of development. His theory also focuses on the social expectations that are found in certain cultures, but not in all. For instance, the idea that adolescence is a time of searching for identity might translate well in the middle-class culture of the United States, but not as well in cultures where the transition into adulthood coincides with puberty through rites of passage and where adult roles offer fewer choices. 24

Behaviorism

While Freud and Erikson looked at what was going on in the mind, behaviorism rejected any reference to mind and viewed overt and observable behavior as the proper subject matter of psychology. Through the scientific study of behavior, it was hoped that laws of learning could be derived that would promote the prediction and control of behavior. 25

Ivan Pavlov

Ivan Pavlov (1880-1937) was a Russian physiologist interested in studying digestion. As he recorded the amount of salivation his laboratory dogs produced as they ate, he noticed that they actually began to salivate before the food arrived as the researcher walked down the hall and toward the cage. “This,” he thought, “is not natural!” One would expect a dog to automatically salivate when food hit their palate, but BEFORE the food comes? Of course, what had happened was . . . you tell me. That’s right! The dogs knew that the food was coming because they had learned to associate the footsteps with the food. The key word here is “learned”. A learned response is called a “conditioned” response.

Figure 1.13 – Ivan Pavlov. 26

Pavlov began to experiment with this concept of classical conditioning . He began to ring a bell, for instance, prior to introducing the food. Sure enough, after making this connection several times, the dogs could be made to salivate to the sound of a bell. Once the bell had become an event to which the dogs had learned to salivate, it was called a conditioned stimulus . The act of salivating to a bell was a response that had also been learned, now termed in Pavlov’s jargon, a conditioned response. Notice that the response, salivation, is the same whether it is conditioned or unconditioned (unlearned or natural). What changed is the stimulus to which the dog salivates. One is natural (unconditioned) and one is learned (conditioned).

Let’s think about how classical conditioning is used on us. One of the most widespread applications of classical conditioning principles was brought to us by the psychologist, John B. Watson.

John B. Watson

John B. Watson (1878-1958) believed that most of our fears and other emotional responses are classically conditioned. He had gained a good deal of popularity in the 1920s with his expert advice on parenting offered to the public.

Figure 1.14 – John B. Watson. 27

He tried to demonstrate the power of classical conditioning with his famous experiment with an 18 month old boy named “Little Albert”. Watson sat Albert down and introduced a variety of seemingly scary objects to him: a burning piece of newspaper, a white rat, etc. But Albert remained curious and reached for all of these things. Watson knew that one of our only inborn fears is the fear of loud noises so he proceeded to make a loud noise each time he introduced one of Albert’s favorites, a white rat. After hearing the loud noise several times paired with the rat, Albert soon came to fear the rat and began to cry when it was introduced. Watson filmed this experiment for posterity and used it to demonstrate that he could help parents achieve any outcomes they desired, if they would only follow his advice. Watson wrote columns in newspapers and in magazines and gained a lot of popularity among parents eager to apply science to household order.

Operant conditioning, on the other hand, looks at the way the consequences of a behavior increase or decrease the likelihood of a behavior occurring again. So let’s look at this a bit more.

B.F. Skinner and Operant Conditioning

B. F. Skinner (1904-1990), who brought us the principles of operant conditioning, suggested that reinforcement is a more effective means of encouraging a behavior than is criticism or punishment. By focusing on strengthening desirable behavior, we have a greater impact than if we emphasize what is undesirable. Reinforcement is anything that an organism desires and is motivated to obtain.

Figure 1.15 – B. F. Skinner. 28

A reinforcer is something that encourages or promotes a behavior. Some things are natural rewards. They are considered intrinsic or primary because their value is easily understood. Think of what kinds of things babies or animals such as puppies find rewarding.

Extrinsic or secondary reinforcers are things that have a value not immediately understood. Their value is indirect. They can be traded in for what is ultimately desired.

The use of positive reinforcement involves adding something to a situation in order to encourage a behavior. For example, if I give a child a cookie for cleaning a room, the addition of the cookie makes cleaning more likely in the future. Think of ways in which you positively reinforce others.

Negative reinforcement occurs when taking something unpleasant away from a situation encourages behavior. For example, I have an alarm clock that makes a very unpleasant, loud sound when it goes off in the morning. As a result, I get up and turn it off. By removing the noise, I am reinforced for getting up. How do you negatively reinforce others?

Punishment is an effort to stop a behavior. It means to follow an action with something unpleasant or painful. Punishment is often less effective than reinforcement for several reasons. It doesn’t indicate the desired behavior, it may result in suppressing rather than stopping a behavior, (in other words, the person may not do what is being punished when you’re around, but may do it often when you leave), and a focus on punishment can result in not noticing when the person does well.

Not all behaviors are learned through association or reinforcement. Many of the things we do are learned by watching others. This is addressed in social learning theory.

Social Learning Theory

Albert Bandura (1925-) is a leading contributor to social learning theory. He calls our attention to the ways in which many of our actions are not learned through conditioning; rather, they are learned by watching others (1977). Young children frequently learn behaviors through imitation

Figure 1.16 – Albert Bandura. 29

Sometimes, particularly when we do not know what else to do, we learn by modeling or copying the behavior of others. A kindergartner on his or her first day of school might eagerly look at how others are acting and try to act the same way to fit in more quickly. Adolescents struggling with their identity rely heavily on their peers to act as role-models. Sometimes we do things because we’ve seen it pay off for someone else. They were operantly conditioned, but we engage in the behavior because we hope it will pay off for us as well. This is referred to as vicarious reinforcement (Bandura, Ross and Ross, 1963).

Bandura (1986) suggests that there is interplay between the environment and the individual. We are not just the product of our surroundings, rather we influence our surroundings. Parents not only influence their child’s environment, perhaps intentionally through the use of reinforcement, etc., but children influence parents as well. Parents may respond differently with their first child than with their fourth. Perhaps they try to be the perfect parents with their firstborn, but by the time their last child comes along they have very different expectations both of themselves and their child. Our environment creates us and we create our environment. 30

Theories also explore cognitive development and how mental processes change over time.

Jean Piaget’s Theory of Cognitive Development

Jean Piaget (1896-1980) is one of the most influential cognitive theorists. Piaget was inspired to explore children’s ability to think and reason by watching his own children’s development. He was one of the first to recognize and map out the ways in which children’s thought differs from that of adults. His interest in this area began when he was asked to test the IQ of children and began to notice that there was a pattern in their wrong answers. He believed that children’s intellectual skills change over time through maturation. Children of differing ages interpret the world differently.

Figure 1.17 – Jean Piaget. 32

Piaget believed our desire to understand the world comes from a need for cognitive equilibrium . This is an agreement or balance between what we sense in the outside world and what we know in our minds. If we experience something that we cannot understand, we try to restore the balance by either changing our thoughts or by altering the experience to fit into what we do understand. Perhaps you meet someone who is very different from anyone you know. How do you make sense of this person? You might use them to establish a new category of people in your mind or you might think about how they are similar to someone else.

A schema or schemes are categories of knowledge. They are like mental boxes of concepts. A child has to learn many concepts. They may have a scheme for “under” and “soft” or “running” and “sour”. All of these are schema. Our efforts to understand the world around us lead us to develop new schema and to modify old ones.

One way to make sense of new experiences is to focus on how they are similar to what we already know. This is assimilation . So the person we meet who is very different may be understood as being “sort of like my brother” or “his voice sounds a lot like yours.” Or a new food may be assimilated when we determine that it tastes like chicken!

Another way to make sense of the world is to change our mind. We can make a cognitive accommodation to this new experience by adding new schema. This food is unlike anything I’ve tasted before. I now have a new category of foods that are bitter-sweet in flavor, for instance. This is  accommodation . Do you accommodate or assimilate more frequently? Children accommodate more frequently as they build new schema. Adults tend to look for similarity in their experience and assimilate. They may be less inclined to think “outside the box.”

Piaget suggested different ways of understanding that are associated with maturation. He divided this into four stages:

Table 1.4 – Jean Piaget’s Theory of Cognitive Development

Criticisms of Piaget’s Theory

Piaget has been criticized for overemphasizing the role that physical maturation plays in cognitive development and in underestimating the role that culture and interaction (or experience) plays in cognitive development. Looking across cultures reveals considerable variation in what children are able to do at various ages. Piaget may have underestimated what children are capable of given the right circumstances. 33

Lev Vygotsky’s Sociocultural Theory

Lev Vygotsky (1896-1934) was a Russian psychologist who wrote in the early 1900s but whose work was discovered in the United States in the 1960s but became more widely known in the 1980s. Vygotsky differed with Piaget in that he believed that a person not only has a set of abilities, but also a set of potential abilities that can be realized if given the proper guidance from others. His sociocultural theory emphasizes the importance of culture and interaction in the development of cognitive abilities. He believed that through guided participation known as scaffolding, with a teacher or capable peer, a child can learn cognitive skills within a certain range known as the zone of proximal development . 34 His belief was that development occurred first through children’s immediate social interactions, and then moved to the individual level as they began to internalize their learning. 35

Figure 1.18- Lev Vygotsky. 36

Have you ever taught a child to perform a task? Maybe it was brushing their teeth or preparing food. Chances are you spoke to them and described what you were doing while you demonstrated the skill and let them work along with you all through the process. You gave them assistance when they seemed to need it, but once they knew what to do-you stood back and let them go. This is scaffolding and can be seen demonstrated throughout the world. This approach to teaching has also been adopted by educators. Rather than assessing students on what they are doing, they should be understood in terms of what they are capable of doing with the proper guidance. You can see how Vygotsky would be very popular with modern day educators. 37

Comparing Piaget and Vygotsky

Vygotsky concentrated more on the child’s immediate social and cultural environment and his or her interactions with adults and peers. While Piaget saw the child as actively discovering the world through individual interactions with it, Vygotsky saw the child as more of an apprentice, learning through a social environment of others who had more experience and were sensitive to the child’s needs and abilities. 38

Like Vygotsky’s, Bronfenbrenner looked at the social influences on learning and development.

Urie Bronfenbrenner’s Ecological Systems Model

Urie Bronfenbrenner (1917-2005) offers us one of the most comprehensive theories of human development. Bronfenbrenner studied Freud, Erikson, Piaget, and learning theorists and believed that all of those theories could be enhanced by adding the dimension of context. What is being taught and how society interprets situations depends on who is involved in the life of a child and on when and where a child lives.

Figure 1.19 – Urie Bronfenbrenner. 39

Bronfenbrenner’s ecological systems model explains the direct and indirect influences on an individual’s development.

Table 1.5 – Urie Bronfenbrenner’s Ecological Systems Model

For example, in order to understand a student in math, we can’t simply look at that individual and what challenges they face directly with the subject. We have to look at the interactions that occur between teacher and child. Perhaps the teacher needs to make modifications as well. The teacher may be responding to regulations made by the school, such as new expectations for students in math or constraints on time that interfere with the teacher’s ability to instruct. These new demands may be a response to national efforts to promote math and science deemed important by political leaders in response to relations with other countries at a particular time in history.

Figure 1.20 – Bronfenbrenner’s ecological systems theory. 40

Bronfenbrenner’s ecological systems model challenges us to go beyond the individual if we want to understand human development and promote improvements. 41

Methods of studying children: the background

This page was published over 5 years ago. Please be aware that due to the passage of time, the information provided on this page may be out of date or otherwise inaccurate, and any views or opinions expressed may no longer be relevant. Some technical elements such as audio-visual and interactive media may no longer work. For more detail, see how we deal with older content .

The three methods most commonly used by Developmental Psychologists to study children are:

1: Cross-sectional studies - comparisons are made of the behaviour or abilities of two or more different groups of children, with each group covering a different age range. This makes it less expensive to carry out the study, and results are gained faster, as the investigator does not have to wait for the children to get older! An example of a cross sectional study is the research we are carrying out as part of OpenLearn's  Child of Our Time website. Explore some of the results .

2: longitudinal studies - a group of children is followed up across time, this could be a relatively short period of several months, or in some cases for decades. as a result, the same children are seen at all of the ages being studied..

The Child of Our Time series is one example of a longitudinal study, with a relatively small group of children.

The Millennium Cohort Study is an example of a large scale longitudinal investigation, following a much larger number of children who were also born at the beginning of this century.

3: Case Studies - one or a very small number of children are seen regularly over a period of time. The time period is variable but usually is six months or more in length. There are some important diary studies which adopt this approach. The advantage of this method is that it can provide a very rich and detailed picture of development as well as providing insights into topics that should be investigated in a larger sample of children.

The Child of Our Time project is a longitudinal study, and the way it is reported also involves case studies of individual children and their families.

On This Page:

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

Cross-Sectional Research Methods

Longitudinal research methods, correlational research methods, experimental research methods.

There are many different developmental psychology research methods, including cross-sectional, longitudinal, correlational, and experimental. Each has its own specific advantages and disadvantages. The one that a scientist chooses depends largely on the aim of the study and the nature of the phenomenon being studied.

Research design provides a standardized framework to test a hypothesis and evaluate whether the hypothesis is correct, incorrect, or inconclusive. Even if the hypothesis is untrue, the research can often provide insights that may prove valuable or move research in an entirely new direction.

At a Glance

In order to study developmental psychology, researchers utilize a number of different research methods. Some involve looking at different cross-sections of a population, while others look at how participants change over time. In other cases, researchers look at how whether certain variables appear to have a relationship with one another. In order to determine if there is a cause-and-effect relationship, however, psychologists much conduct experimental research.

Learn more about each of these different types of developmental psychology research methods, including when they are used and what they can reveal about human development.

Cross-sectional research involves looking at different groups of people with specific characteristics.

For example, a researcher might evaluate a group of young adults and compare the corresponding data from a group of older adults.

The benefit of this type of research is that it can be done relatively quickly; the research data is gathered at the same point in time. The disadvantage is that the research aims to make a direct association between a cause and an effect. This is not always so easy. In some cases, there may be confounding factors that contribute to the effect.

To this end, a cross-sectional study can suggest the odds of an effect occurring both in terms of the absolute risk (the odds of something happening over a period of time) and the relative risk (the odds of something happening in one group compared to another).  

Longitudinal research involves studying the same group of individuals over an extended period of time.

Data is collected at the outset of the study and gathered repeatedly through the course of study. In some cases, longitudinal studies can last for several decades or be open-ended. One such example is the Terman Study of the Gifted , which began in the 1920s and followed 1528 children for over 80 years.

The benefit of this longitudinal research is that it allows researchers to look at changes over time. By contrast, one of the obvious disadvantages is cost. Because of the expense of a long-term study, they tend to be confined to a smaller group of subjects or a narrower field of observation.

Challenges of Longitudinal Research

While revealing, longitudinal studies present a few challenges that make them more difficult to use when studying developmental psychology and other topics.

• Longitudinal studies are difficult to apply to a larger population.
• Another problem is that the participants can often drop out mid-study, shrinking the sample size and relative conclusions.
• Moreover, if certain outside forces change during the course of the study (including economics, politics, and science), they can influence the outcomes in a way that significantly skews the results.

For example, in Lewis Terman's longitudinal study, the correlation between IQ and achievement was blunted by such confounding forces as the Great Depression and World War II (which limited educational attainment) and gender politics of the 1940s and 1950s (which limited a woman's professional prospects).

Correlational research aims to determine if one variable has a measurable association with another.

In this type of non-experimental study, researchers look at relationships between the two variables but do not introduce the variables themselves. Instead, they gather and evaluate the available data and offer a statistical conclusion.

For example, the researchers may look at whether academic success in elementary school leads to better-paying jobs in the future. While the researchers can collect and evaluate the data, they do not manipulate any of the variables in question.

A correlational study can be appropriate and helpful if you cannot manipulate a variable because it is impossible, impractical, or unethical.

For example, imagine that a researcher wants to determine if living in a noisy environment makes people less efficient in the workplace. It would be impractical and unreasonable to artificially inflate the noise level in a working environment. Instead, researchers might collect data and then look for correlations between the variables of interest.

Limitations of Correlational Research

Correlational research has its limitations. While it can identify an association, it does not necessarily suggest a cause for the effect. Just because two variables have a relationship does not mean that changes in one will affect a change in the other.

Unlike correlational research, experimentation involves both the manipulation and measurement of variables . This model of research is the most scientifically conclusive and commonly used in medicine, chemistry, psychology, biology, and sociology.

Experimental research uses manipulation to understand cause and effect in a sampling of subjects. The sample is comprised of two groups: an experimental group in whom the variable (such as a drug or treatment) is introduced and a control group in whom the variable is not introduced.

Deciding the sample groups can be done in a number of ways:

• Population sampling, in which the subjects represent a specific population
• Random selection , in which subjects are chosen randomly to see if the effects of the variable are consistently achieved

Challenges in Experimental Resarch

While the statistical value of an experimental study is robust, it may be affected by confirmation bias . This is when the investigator's desire to publish or achieve an unambiguous result can skew the interpretations, leading to a false-positive conclusion.

One way to avoid this is to conduct a double-blind study in which neither the participants nor researchers are aware of which group is the control. A double-blind randomized controlled trial (RCT) is considered the gold standard of research.

What This Means For You

There are many different types of research methods that scientists use to study developmental psychology and other areas. Knowing more about how each of these methods works can give you a better understanding of what the findings of psychological research might mean for you.

Case Studies and Scenarios

Case studies.

Each case study describes the real experience of a Registered Early Childhood Educator. Each one profiles a professional dilemma, incorporates participants with multiple perspectives and explores ethical complexities. Case studies may be used as a source for reflection and dialogue about RECE practice within the framework of the Code of Ethics and Standards of Practice​.

Scenarios are snapshots of experiences in the professional practice of a Registered Early Childhood Educator. Each scenario includes a series of questions meant to help RECEs reflect on the situation.

Case Study 1: Sara’s Confusing Behaviour

Case study 2: getting bumps and taking lumps, case study 3: no qualified staff, case study 4: denton’s birthday cupcakes, case study 5: new kid on the block, case study 6: new responsibilities and challenges, case study 7: valuing inclusivity and privacy, case study 8: balancing supervisory responsibilities, case study 9: once we were friends, ​​​​scenarios​​, communication and collaboration.

Barbara, an RECE, is working as a supply staff at various centres across the city. During her week at a centre where she helps out in two different rooms each day, she finds that her experience in the school-age program isn’t as straightforward as when she was in the toddler room. Barbara feels completely lost in this program.

Do You Really Know Who Your Friends Are?

Joe is an RECE at an elementary school and works with children between the ages of nine and 12 years old. One afternoon, he finds a group of children huddled around the computer giggling and whispering. Joe quickly discovers they’re going through his party photos on Facebook as one of the children’s parents recently added him as a friend.

Conflicting Approaches

Amina, an experienced RECE, has recently started a new position with a child care centre. She’s assigned to work in the infant room with two colleagues who have worked in the room together for ten years. As Amina settles into her new role, she is taken aback by some of the child care approaches taken by her colleagues.

What to do about Lisa?

Shane, an experienced supervisor at a child care centre, receives a complaint about an RECE who had roughly handled a child earlier that day. The interaction had been witnessed by a parent who confronted the RECE. After some words were exchanged, the RECE left in tears.

Duty to Report

Zoë works as an RECE in a drop-in program at a family support centre. She has a great rapport for a family over a 10-month period and beings to notice a change in the mom and child. One day, as the child is getting dressed to go home for the day, she notices something alarming and brings it to the attention of her supervisor.

Posting on Social Media

Allie, an RECE who has worked at the same child care centre for the last three years, recently started a private social media group to collaborate and discuss programming ideas. As the group takes a negative turn with rude and offensive comments, it’s brought to her supervisor’s attention.

Case Study-Based Learning

Enhancing learning through immediate application.

By the Mind Tools Content Team

If you've ever tried to learn a new concept, you probably appreciate that "knowing" is different from "doing." When you have an opportunity to apply your knowledge, the lesson typically becomes much more real.

Adults often learn differently from children, and we have different motivations for learning. Typically, we learn new skills because we want to. We recognize the need to learn and grow, and we usually need – or want – to apply our newfound knowledge soon after we've learned it.

A popular theory of adult learning is andragogy (the art and science of leading man, or adults), as opposed to the better-known pedagogy (the art and science of leading children). Malcolm Knowles , a professor of adult education, was considered the father of andragogy, which is based on four key observations of adult learners:

• Adults learn best if they know why they're learning something.
• Adults often learn best through experience.
• Adults tend to view learning as an opportunity to solve problems.
• Adults learn best when the topic is relevant to them and immediately applicable.

This means that you'll get the best results with adults when they're fully involved in the learning experience. Give an adult an opportunity to practice and work with a new skill, and you have a solid foundation for high-quality learning that the person will likely retain over time.

So, how can you best use these adult learning principles in your training and development efforts? Case studies provide an excellent way of practicing and applying new concepts. As such, they're very useful tools in adult learning, and it's important to understand how to get the maximum value from them.

What Is a Case Study?

Case studies are a form of problem-based learning, where you present a situation that needs a resolution. A typical business case study is a detailed account, or story, of what happened in a particular company, industry, or project over a set period of time.

The learner is given details about the situation, often in a historical context. The key players are introduced. Objectives and challenges are outlined. This is followed by specific examples and data, which the learner then uses to analyze the situation, determine what happened, and make recommendations.

The depth of a case depends on the lesson being taught. A case study can be two pages, 20 pages, or more. A good case study makes the reader think critically about the information presented, and then develop a thorough assessment of the situation, leading to a well-thought-out solution or recommendation.

Why Use a Case Study?

Case studies are a great way to improve a learning experience, because they get the learner involved, and encourage immediate use of newly acquired skills.

They differ from lectures or assigned readings because they require participation and deliberate application of a broad range of skills. For example, if you study financial analysis through straightforward learning methods, you may have to calculate and understand a long list of financial ratios (don't worry if you don't know what these are). Likewise, you may be given a set of financial statements to complete a ratio analysis. But until you put the exercise into context, you may not really know why you're doing the analysis.

With a case study, however, you might explore whether a bank should provide financing to a borrower, or whether a company is about to make a good acquisition. Suddenly, the act of calculating ratios becomes secondary – it's more important to understand what the ratios tell you. This is how case studies can make the difference between knowing what to do, and knowing how, when, and why to do it.

Then, what really separates case studies from other practical forms of learning – like scenarios and simulations – is the ability to compare the learner's recommendations with what actually happened. When you know what really happened, it's much easier to evaluate the "correctness" of the answers given.

When to Use a Case Study

As you can see, case studies are powerful and effective training tools. They also work best with practical, applied training, so make sure you use them appropriately.

Remember these tips:

• Case studies tend to focus on why and how to apply a skill or concept, not on remembering facts and details. Use case studies when understanding the concept is more important than memorizing correct responses.
• Case studies are great team-building opportunities. When a team gets together to solve a case, they'll have to work through different opinions, methods, and perspectives.
• Use case studies to build problem-solving skills, particularly those that are valuable when applied, but are likely to be used infrequently. This helps people get practice with these skills that they might not otherwise get.
• Case studies can be used to evaluate past problem solving. People can be asked what they'd do in that situation, and think about what could have been done differently.

Ensuring Maximum Value From Case Studies

The first thing to remember is that you already need to have enough theoretical knowledge to handle the questions and challenges in the case study. Otherwise, it can be like trying to solve a puzzle with some of the pieces missing.

Here are some additional tips for how to approach a case study. Depending on the exact nature of the case, some tips will be more relevant than others.

• Read the case at least three times before you start any analysis. Case studies usually have lots of details, and it's easy to miss something in your first, or even second, reading.
• Once you're thoroughly familiar with the case, note the facts. Identify which are relevant to the tasks you've been assigned. In a good case study, there are often many more facts than you need for your analysis.
• If the case contains large amounts of data, analyze this data for relevant trends. For example, have sales dropped steadily, or was there an unexpected high or low point?
• If the case involves a description of a company's history, find the key events, and consider how they may have impacted the current situation.
• Consider using techniques like SWOT analysis and Porter's Five Forces Analysis to understand the organization's strategic position.
• Stay with the facts when you draw conclusions. These include facts given in the case as well as established facts about the environmental context. Don't rely on personal opinions when you put together your answers.

Writing a Case Study

You may have to write a case study yourself. These are complex documents that take a while to research and compile. The quality of the case study influences the quality of the analysis. Here are some tips if you want to write your own:

• Write your case study as a structured story. The goal is to capture an interesting situation or challenge and then bring it to life with words and information. You want the reader to feel a part of what's happening.
• Present information so that a "right" answer isn't obvious. The goal is to develop the learner's ability to analyze and assess, not necessarily to make the same decision as the people in the actual case.
• Do background research to fully understand what happened and why. You may need to talk to key stakeholders to get their perspectives as well.
• Determine the key challenge. What needs to be resolved? The case study should focus on one main question or issue.
• Define the context. Talk about significant events leading up to the situation. What organizational factors are important for understanding the problem and assessing what should be done? Include cultural factors where possible.
• Identify key decision makers and stakeholders. Describe their roles and perspectives, as well as their motivations and interests.
• Make sure that you provide the right data to allow people to reach appropriate conclusions.
• Make sure that you have permission to use any information you include.

A typical case study structure includes these elements:

• Executive summary. Define the objective, and state the key challenge.
• Opening paragraph. Capture the reader's interest.
• Scope. Describe the background, context, approach, and issues involved.
• Presentation of facts. Develop an objective picture of what's happening.
• Description of key issues. Present viewpoints, decisions, and interests of key parties.

Because case studies have proved to be such effective teaching tools, many are already written. Some excellent sources of free cases are The Times 100 , CasePlace.org , and Schroeder & Schroeder Inc . You can often search for cases by topic or industry. These cases are expertly prepared, based mostly on real situations, and used extensively in business schools to teach management concepts.

Case studies are a great way to improve learning and training. They provide learners with an opportunity to solve a problem by applying what they know.

There are no unpleasant consequences for getting it "wrong," and cases give learners a much better understanding of what they really know and what they need to practice.

Case studies can be used in many ways, as team-building tools, and for skill development. You can write your own case study, but a large number are already prepared. Given the enormous benefits of practical learning applications like this, case studies are definitely something to consider adding to your next training session.

This text covers some topics with more detail than necessary (e.g., detailing infant urination) yet it lacks comprehensiveness in a few areas that may need revision. For example, the text discusses issues with vaccines and offers a 2018 vaccine schedule for infants. The text brushes over “commonly circulated concerns” regarding vaccines and dispels these with statements about the small number of antigens a body receives through vaccines versus the numerous antigens the body normally encounters. With changes in vaccines currently offered, shifting CDC viewpoints on recommendations, and changing requirements for vaccine regulations among vaccine producers, the authors will need to revisit this information to comprehensively address all recommended vaccines, potential risks, and side effects among other topics in the current zeitgeist of our world.

Content Accuracy rating: 3

At face level, the content shared within this book appears accurate. It would be a great task to individually check each in-text citation and determine relevance, credibility and accuracy. It is notable that many of the citations, although this text was updated in 2019, remain outdated. Authors could update many of the in-text citations for current references. For example, multiple in-text citations refer to the March of Dimes and many are dated from 2012 or 2015. To increase content accuracy, authors should consider revisiting their content and current citations to determine if these continue to be the most relevant sources or if revisions are necessary. Finally, readers could benefit from a reference list in this textbook. With multiple in-text citations throughout the book, it is surprising no reference list is provided.

Relevance/Longevity rating: 4

This text would be ideal for an introduction to child development course and could possibly be used in a high school dual credit or beginning undergraduate course or certificate program such as a CDA. The outdated citations and formatting in APA 6th edition cry out for updating. Putting those aside, the content provides a solid base for learners interested in pursuing educational domains/careers relevant to child development. Certain issues (i.e., romantic relationships in adolescence, sexual orientation, and vaccination) may need to be revisited and updated, or instructors using this text will need to include supplemental information to provide students with current research findings and changes in these areas.

Clarity rating: 4

The text reads like an encyclopedia entry. It provides bold print headers and brief definitions with a few examples. Sprinkled throughout the text are helpful photographs with captions describing the images. The words chosen in the text are relatable to most high school or undergraduate level readers and do not burden the reader with expert level academic vocabulary. The layout of the text and images is simple and repetitive with photographs complementing the text entries. This allows the reader to focus their concentration on comprehension rather than deciphering a more confusing format. An index where readers could go back and search for certain terms within the textbook would be helpful. Additionally, a glossary of key terms would add clarity to this textbook.

Consistency rating: 5

Chapters appear in a similar layout throughout the textbook. The reader can anticipate the flow of the text and easily identify important terms. Authors utilized familiar headings in each chapter providing consistency to the reader.

Modularity rating: 4

Given the repetitive structure and the layout of the topics by developmental issues (physical, social emotional) the book could be divided into sections or modules. It would be easier if infancy and fetal development were more clearly distinct and stages of infant development more clearly defined, however the book could still be approached in sections or modules.

Organization/Structure/Flow rating: 4

The text is organized in a logical way when we consider our own developmental trajectories. For this reason, readers learning about these topics can easily relate to the flow of topics as they are presented throughout the book. However, when attempting to find certain topics, the reader must consider what part of development that topic may inhabit and then turn to the portion of the book aligned with that developmental issue. To ease the organization and improve readability as a reference book, authors could implement an index in the back of the book. With an index by topic, readers could quickly turn to pages covering specific topics of interest. Additionally, the text structure could be improved by providing some guiding questions or reflection prompts for readers. This would provide signals for readers to stop and think about their comprehension of the material and would also benefit instructors using this textbook in classroom settings.

Interface rating: 4

The online interface for this textbook did not hinder readability or comprehension of the text. All information including photographs, charts, and diagrams appeared to be clearly depicted within this interface. To ease reading this text online authors should create a live table of contents with bookmarks to the beginning of chapters. This book does not offer such links and therefore the reader must scroll through the pdf to find each chapter or topic.

Grammatical Errors rating: 5

No grammatical errors were found in reviewing this textbook.

Cultural Relevance rating: 3

Cultural diversity is represented throughout this text by way of the topics described and the images selected. The authors provide various perspectives that individuals or groups from multiple cultures may resonate with including parenting styles, developmental trajectories, sexuality, approaches to feeding infants, and the social emotional development of children. This text could expand in the realm of cultural diversity by addressing current issues regarding many of the hot topics in our society. Additionally, this textbook could include other types of cultural diversity aside from geographical location (e.g., religion-based or ability-based differences).

While this text lacks some of the features I would appreciate as an instructor (e.g., study guides, review questions, prompts for critical thinking/reflection) and it does not contain an index or glossary, it would be appropriate as an accessible resource for an introduction to child development. Students could easily access this text and find reliable and easily readable information to build basic content knowledge in this domain.

Each chapter is comprehensively described and organized by the period of development. Although infancy and toddlerhood are grouped together, they are logically organized and discussed within each chapter. One helpful addition that would largely contribute to the comprehensiveness is a glossary of terms at the end of the text.

From my reading, the content is accurate and unbiased. However, it is difficult to confidently respond due to a lack of references. It is sometimes clear where the information came from, but when I followed one link to a citation the link was to another textbook. There are many citations embedded within the text, but it would be beneficial (and helpful for further reading) to have a list of references at the end of each chapter. The references used within the text are also older, so implementing updated references would also enhance accuracy. If used for a course, instructors will need to supplement the textbook readings with other materials.

This text can be implemented for many semesters to come, though as previously discussed, further readings and updated materials can be used to supplement this text. It provides a good foundation for students to read prior to lectures.

Clarity rating: 5

This text is unique in its writing style for a textbook. It is written in a way that is easily accessible to students and is also engaging. The text doesn't overly use jargon or provide complex, long-winded examples. The examples used are clear and concise. Many key terms are in bold which is helpful to the reader.

For the terms that are in bold, it would be helpful to have a definition of the term listed separately on the page within the side margins, as well as include the definition in a glossary at the end.

Each period of development is consistently described by first addressing physical development, cognitive development, and then social-emotional development.

Modularity rating: 5

This text is easily divisible to assign to students. There were few (if any) large blocks of texts without subheadings, graphs, or images. This feature not only improves modularity but also promotes engagement with the reading.

Organization/Structure/Flow rating: 5

The organization of the text flows logically. I appreciate the order of the topics, which are clearly described in the first chapter by each period of development. Although infancy and toddlerhood are grouped into one period of development, development is appropriately described for both infants and toddlers. Key theories are discussed for infants and toddlers and clearly presented for the appropriate age.

Interface rating: 5

There were no significant interface issues. No images or charts were distorted.

It would be helpful to the reader if the table of contents included a navigation option, but this doesn't detract from the overall interface.

I did not see any grammatical errors.

This text includes some cultural examples across each area of development, such as differences in first words, parenting styles, personalities, and attachments styles (to list a few). The photos included throughout the text are inclusive of various family styles, races, and ethnicities. This text could implement more cultural components, but does include some cultural examples. Again, instructors can supplement more cultural examples to bolster the reading.

This text is a great introductory text for students. The text is written in a fun, approachable way for students. Though the text is not as interactive (e.g., further reading suggestions, list of references, discussion points at the end of each chapter, etc.), this is a great resource to cover development that is open access.

This text is very thorough in its coverage of child and adolescent development. Important theories and frameworks in developmental psychology are discussed in appropriate depth. There is no glossary of terms at the end of the text, but I do not think this really hurts its comprehensiveness.

Content Accuracy rating: 5

The citations throughout the textbook help to ensure its accuracy. However, the text could benefit from additional references to recent empirical studies in the developmental field.

It seems as if updates to this textbook will be relatively easy and straightforward to implement given how well organized the text is and its numerous sections and subsections. For example, a recent narrative review was published on the effects of corporal punishment (Heilmann et al., 2021). The addition of a reference to this review, and other more recent work on spanking and other forms of corporal punishment, could serve to update the text's section on spanking (pp. 223-224; p. 418).

The text is very clear and easily understandable.

Consistency rating: 4

There do not appear to be any inconsistencies in the text. The lack of a glossary at the end of the text may be a limitation in this area, however, since glossaries can help with consistent use of language or clarify when different terms are used.

This textbook does an excellent job of dividing up and organizing its chapters. For example, chapters start with bulleted objectives and end with a bulleted conclusion section. Within each chapter, there are many headings and subheadings, making it easy for the reader to methodically read through the chapter or quickly identify a section of interest. This would also assist in assigning reading on specific topics. Additionally, the text is broken up by relevant photos, charts, graphs, and diagrams, depending on the topic being discussed.

This textbook takes a chronological approach. The broad developmental stages covered include, in order, birth and the newborn, infancy and toddlerhood, early childhood, middle childhood, and adolescence. Starting with the infancy and toddlerhood stage, physical, cognitive, and social emotional development are covered.

There are no interface issues with this textbook. It is easily accessible as a PDF file. Images are clear and there is no distortion apparent.

I did not notice any grammatical errors.

Cultural Relevance rating: 4

This text does a good job of including content relevant to different cultures and backgrounds. One example of this is in the "Cultural Influences on Parenting Styles" subsection (p. 222). Here the authors discuss how socioeconomic status and cultural background can affect parenting styles. Including references to specific studies could further strengthen this section, and, more broadly, additional specific examples grounded in research could help to fortify similar sections focused on cultural differences.

Overall, I think this is a terrific resource for a child and adolescent development course. It is user-friendly and comprehensive.

The text is excellent for its content and presentation. The only criticism is that neither an index nor a glossary are provided.

The material seems very accurate and current. It is well written. It is very professionally done and is accessible to students.

This text addresses topics that will serve this field in positive ways that should be able to address the needs of students and instructors for the next several years.

Complex concepts are delivered accurately and are still accessible for students . Figures and tables complement the text . Terms are explained and are embedded in the text, not in a glossary. I do think indices and glossaries are helpful tools. Terminology is highlighted with bold fonts to accentuate definitions.

Yes the text is consistent in its format. As this is a text on Child Development it consistently addresses each developmental domain and then repeats the sequence for each age group in childhood. It is very logically presented.

Yes this text is definitely divisible. This text addresses development from conception to adolescents. For the community college course that my department wants to use it is very adaptable. Our course ends at middle school age development; our courses are offered on a quarter system. This text is adaptable for the content and our term time schedule.

This text book flows very clearly from Basic principles to Conception. It then divides each stage of development into Physical, Cognitive and Social Emotional development. Those concepts and information are then repeated for each stage of development. e.g. Infants and Toddler-hood, Early Childhood, and Middle Childhood. It is very clearly presented.

It is very professionally presented. It is quite attractive in its presentation .

I saw no errors

The text appears to be aware of being diverse and inclusive both in its content and its graphics. It discusses culture and represents a variety of family structures representing contemporary society.

It is wonderfully researched. It will serve our students well. It is comprehensive and constructed very well. I have enjoyed getting familiar with this text and am looking forward to using it with my students in this upcoming term.

This is a highly comprehensive, chronological text that covers genetics and conception through adolescence. All major topics and developmental milestones in each age range are given adequate space and consideration. The authors take care to summarize debates and controversies, when relevant and include a large amount of applied / practical material. For example, beyond infant growth patterns and motor milestone, the infancy/toddler chapters spend several pages on the mechanics of car seat safety, best practices for introducing solid foods (and the rationale), and common concerns like diaper rash. In addition to being generally useful information for students who are parents, or who may go on to be parents, this text takes care to contextualize the psychological research in the lived experiences of children and their parents. This is an approach that I find highly valuable. While the text does not contain an index, the search & find capacity of OER to make an index a deal-breaker for me.

The text includes accurate information that is well-sourced. Relevant debates, controversies and historical context is also provided throughout which results in a rich, balanced text.

This text provides an excellent summary of classic and updated developmental work. While the majority of the text is skewed toward dated, classic work, some updated research is included. Instructors may wish to supplement this text with more recent work, particularly that which includes diverse samples and specifically addresses topics of class, race, gender and sexual orientation (see comment below regarding cultural aspects).

The text is written in highly accessible language, free of jargon. Of particular value are the many author-generated tables which clearly organize and display critical information. The authors have also included many excellent figures, which reinforce and visually organize the information presented.

This text is consistent in its use of terminology. Balanced discussion of multiple theoretical frameworks are included throughout, with adequate space provided to address controversies and debates.

The text is clearly organized and structured. Each chapter is self-contained. In places where the authors do refer to prior or future chapters (something that I find helps students contextualize their reading), a complete discussion of the topic is included. While this may result in repetition for students reading the text from cover to cover, the repetition of some content is not so egregious that it outweighs the benefit of a flexible, modular textbook.

Excellent, clear organization. This text closely follows the organization of published textbooks that I have used in the past for both lifespan and child development. As this text follows a chronological format, a discussion of theory and methods, and genetics and prenatal growth is followed by sections devoted to a specific age range: infancy and toddlerhood, early childhood (preschool), middle childhood and adolescence. Each age range is further split into three chapters that address each developmental domain: physical, cognitive and social emotional development.

All text appears clearly and all images, tables and figures are positioned correctly and free of distortion.

The text contains no spelling or grammatical errors.

While this text provides adequate discussion of gender and cross-cultural influences on development, it is not sufficient. This is not a problem unique to this text, and is indeed a critique I have of all developmental textbooks. In particular, in my view this text does not adequately address the role of race, class or sexual orientation on development.

All in all, this is a comprehensive and well-written textbook that very closely follows the format of standard chronologically-organized child development textbooks. This is a fantastic alternative for those standard texts, with the added benefit of language that is more accessible, and content that is skewed toward practical applications.

The subject of this book is Child Growth and Development and as such covers all areas and ideas appropriate for this subject. This book has an appropriate index. The author starts out with a comprehensive overview of Child Development in the Introduction. The principles of development were delineated and were thoroughly presented in a very understandable way. Nine theories were presented which gave the reader an understanding of the many authors who have contributed to Child Development. A good backdrop to start a conversation. This book discusses the early beginnings starting with Conception, Hereditary and Prenatal stages which provides a foundation for the future developmental stages such as infancy, toddler, early childhood, middle childhood and adolescence. The three domains of developmental psychology – physical, cognitive and social emotional are entertained with each stage of development. This book is thoroughly researched and is written in a way to not overwhelm. Language is concise and easily understood.

This book has all the features you would want. There are textbooks that try to cover too much in one chapter. In this book the sections are clearly identified and divided into smaller and digestible parts so the reader can easily comprehend the topic under discussion. This book easily flows from one subject to the next. Blocks of information are being built, one brick on top of another as you move through the domains of development and the stages of development.

This book starts out with a comprehensive overview in the introduction to child development. From that point forward it is organized into the various stages of development and flows well.

This book is organized by developmental stages (infancy, toddler, early childhood, middle childhood and adolescence). The book begins with an overview of conception and prenatal human development. An entire chapter is devoted to birth and expectations of newborns. In addition, there is a consistency to each developmental stage. For infancy, early childhood, middle childhood, and adolescence, the textbook covers physical development, cognitive development, and social emotional development for each stage. While some textbooks devote entire chapters to themes such as physical development, cognitive development, and social emotional development and write about how children change developmentally in each stage this book focuses on human stages of development. The book is written in clear language and is easy to understand.

There is so much information in this book that it is a very good overview of child development. The content is error-free and unbiased. In some spots it briefly introduces multicultural traditions, beliefs, and attitudes. It is accurate for the citations that have been provided. However, it could benefit from updating to research that has been done recently. I believe that if the instructor supplements this text with current peer-reviewed research and organizations that are implementing what the book explains, this book will serve as a strong source of information.

While the book covers a very broad range of topics, many times the citations have not been updated and are often times dated. The content and information that is provided is correct and accurate, but this text can certainly benefit from having the latest research added. It does, however, include a great many topics that serve to inform students well.

The text is very easy to understand. It is written in a way that first and second year college students will find easy to understand. It also introduces students to current child and adolescent behavior that is important to be understood on an academic level. It does this in a comprehensive and clear manner.

This book is very consistent. The chapters are arranged by developmental stage. Even within each chapter there is a consistency of theorists. For example, each chapter begins with Piaget, then moves to Vygotsky, etc. This allows for great consistency among chapters. If I as the instructor decide to have students write about Piaget and his development theories throughout the life span, students will easily know that they can find this information in the first few pages of each chapter.

Certainly instructors will find the modularity of this book easy. Within each chapter the topics are self-contained and extensive. As I read the textbook, I envisioned myself perhaps not assigning entire chapters but assigning specific topics/modules and pages that students can read. I believe the modules can be used as a strong foundational reading to introduce students to concepts and then have students read supplemental information from primary sources or journals to reinforce what they have read in the chapter.

The organization of the book is clear and flows nicely. From the table of context students understand how the book is organized. The textbook would be even stronger if there was a more detailed table of context which highlights what topics are covered within each of the chapter. There is so much information contained within each chapter that it would be very beneficial to both students and instructor to quickly see what content and topics are covered in each chapter.

The interface is fine and works well.

The text is free from grammatical errors.

While the textbook does introduce some multicultural differences and similarities, it does not delve deeply into multiracial and multiethnic issues within America. It also offers very little comment on differences that occur among urban, rural, and suburban experiences. In addition, while it does talk about maturation and sexuality, LGBTQ issues could be more prominent.

Overall I enjoyed this text and will strongly consider using it in my course. The focus is clearly on human development and has very little emphasis on education. However, I intend to supplement this text with additional readings and videos that will show concrete examples of the concepts which are introduced in the text. It is a strong and worthy alternative to high-priced textbooks.

About the book.

Welcome to Child Growth and Development. This text is a presentation of how and why children grow, develop, and learn. We will look at how we change physically over time from conception through adolescence. We examine cognitive change, or how our ability to think and remember changes over the first 20 years or so of life. And we will look at how our emotions, psychological state, and social relationships change throughout childhood and adolescence.

Methods of studying Child behaviour and development

Back to: Early Childhood Care and Education B.ed Notes, IGNOU Notes, M.A Notes, Graduation Notes

Methods of studying child behaviour observation and case study

The collecting and organizing of credible data can be aided by the use of unique instruments, processes, or methodologies in child research. According to Charles Gide, the word “method” refers to the path that must be taken to get at the truth; there are numerous ways that are employed in child psychology. To gather data, psychologists employ a variety of techniques, including observation, experimentation, correlation, surveys, psychological testing, case studies, etc. This article discusses some of the significant techniques that are frequently applied in early childhood development.

Observation method of studying child behaviour

A particularly effective tool for psychological research is observation. It is a useful technique for understanding human behaviour. We spend the entire day in our regular lives observing various things. We frequently fail to realize what we are seeing or have already seen. Although we see, we do not monitor. Only a small portion of what we see every day escapes our awareness.  Scientific observation is very different from regular observation.

• Selection:  Scientists do not always observe every behaviour they come across. Instead, they pick a certain activity to study.
• Recording: A researcher will follow remarks, record counts for previously defined behaviours every time they arise, describe each event in more detail using abbreviations or figures, and take pictures, video footage, or other methods while they are watching.
• Analysis: Following making their observations, analysts examine the information they have gathered to try and make sense of it.  It is crucial to understand that making accurate assessments requires competence. A skilled observer is aware of what he is looking for, whom he wants to read about, when and where the observation has to be performed, how it will be documented, and how to interpret the behaviour they have seen.

Types of Observation Methods in Childcare

• Naturalistic vs. controlled observation: Naturalistic observation refers to the process of making observations in a natural or real-world environment. In this instance, the observer doesn’t try to influence or manipulate the circumstances to conclude. These kinds of observations are made in places like hospitals, residences, classrooms, daycare facilities, etc. Yet, since they are not the subject of our study, there are many instances when you may need to manage certain aspects that affect behaviour. This is why a lot of psychological research uses controlled observation, which is done in lab settings.
• Non-Participant vs. Participant Observation: One can observe in two different ways.  The observer has the option to see the subject or event far away (non-participant observation). The observer could also merge with the group being scrutinized. In the first scenario, the subject of the observation could not be conscious of it.

For example, we’d like to look at how the professors and students in a specific class communicate with one another. This objective can be attained in a variety of ways. The spectator may use a video camera to monitor the happenings in the lecture. He could also choose to remain seated in a quiet area of the classroom and refrain from meddling with or engaging in their regular activities. Non-participant observation is the term for this kind of observation.

When doing participant observation, the investigator joins the class or organization being scrutinized. In participant observation, the analyst spends some time getting to know the members of the group so they begin to appreciate him as a member of the group. Nevertheless, based on the study’s main objective, the spectator’s level of connection with the group under observation may change.

Experimental method of child study

In a controlled environment, experiments are often carried out to determine the cause-and-effect relationship between two sets of occurrences or factors. It is a meticulously planned process where adjustments are made to one aspect and the impact on some other element is examined. In the research, the altered or controlled event is the reason. The impact is the modification in behaviour brought on through influence.

Experiments can be controlled through various techniques:

• The easiest method to solve this issue is to remove unnecessary factors from the experimental setup because the purpose of an experiment is to reduce superfluous factors. For example, the study may be carried out in a quiet area with air conditioning to reduce the impact of disturbance and climate.
• It’s not always possible to avoid. When this occurs, actions should be taken to maintain them consistently so that their impact is consistent across the duration of the experiment.
• Any possible systematic disparities between organizations are eliminated by randomly assigning individuals to multiple organizations.

Case study method of child study

The case study technique is typically applied to people who have behavioural or mental health issues. Identifying the factors impacting behaviour is utilized to rebuild a person’s developmental history. In other words, the case study or case history technique involves tracing a person’s past and noting major life events. With this approach, an effort is made to closely investigate the person’s history to ascertain the origin of his present motivations and behaviours.

A case study refers to a methodical, exhaustive, and thorough examination of a person’s life history, including information on their parents, upbringing, physical, social, psychological, cognitive, and spiritual growth. None is left that can affect the case’s current circumstances, making it easier to grasp the situation better.

Since 2019, the war in Ethiopia between the Federal Government and the Tigrean People’s Liberation Front (TPLF) has severely impacted civilians, including children. Although children have been affected in many of the war-torn regions of the country, the study targeted two specific locations, Maikadra and Chenna, in Amhara National Regional State, where civilians were massacred because of their ethnicity. The focus of the study was to understand the acute and complex child abuse that occurred in the midst of the war. A qualitative method with a descriptive case study design was employed to collect and analyze data. Twenty-four individuals were purposely selected and participated in the interviews. From Maikadra, the participants included seven children, two parents, two school principals, one eyewitness woman in the community, and one Kebele administrator. Similarly, from Chenna, five children, three parents, two school principals, and one Kebele administrator participated in the interviews. We applied in-depth interviews and systematic observation to gather primary data. Using social ecology as a theoretical framework, the result revealed that at the micro level, community members (particularly children) experienced witnessing killings, experience rape and verbal abuse, intimidation, and the destruction of the family unit. At the mezzo level, the study documented communities’ experiences related to displacement and the destruction of schools and community networks. Further, at the exo level, the study revealed experiences of hunger, starvation, and the emergence of child-headed families. Finally, at the macro community level, the study revealed loss of future aspirations and the development of negative attitudes toward cultural values. All these forms of child abuse, as reported by study participants, are crimes deliberately committed by the TPLF rebel groups. This study suggests multiple interventions at all levels are required.

This qualitative case study, conducted in war-torn areas of Ethiopia, sheds light on the various contexts in which children were subjected to abuse.

The war resulted in child abuse that can be explained at micro, mezzo, exo, and macro system levels.

Children were directly targeted and witnessed ethnic-based atrocities. They lost their parents, took on family responsibilities, became orphaned, saw their schools turned into burial sites and were no longer attending school. Their future aspirations have been compromised.

War actors from the TPLF perpetuated negative attitudes towards the Amhara cultural values.
