Developmental Psychology 101: Theories, Stages, & Research

Developmental psychology stages

You can imagine how vast this field of psychology is if it has to cover the whole of life, from birth through death.

Just like any other area of psychology, it has created exciting debates and given rise to fascinating case studies.

In recent years, developmental psychology has shifted to incorporate positive psychology paradigms to create a holistic lifespan approach. As an example, the knowledge gained from positive psychology can enhance the development of children in education.

In this article, you will learn a lot about different aspects of developmental psychology, including how it first emerged in history and famous theories and models.

Human beings change drastically over our lifetime.

The American Psychological Association (2020) defines developmental psychology as the study of physical, mental, and behavioral changes, from conception through old age.

Developmental psychology investigates biological, genetic, neurological, psychosocial, cultural, and environmental factors of human growth (Burman, 2017).

Over the years, developmental psychology has been influenced by numerous theories and models in varied branches of psychology (Burman, 2017).

History of developmental psychology

Developmental psychology first appeared as an area of study in the late 19th century (Baltes, Lindenberger, & Staudinger, 2007). Developmental psychology focused initially on child and adolescent development, and was concerned about children’s minds and learning (Hall, 1883).

There are several key figures in developmental psychology. In 1877, the famous evolutionary biologist Charles Darwin undertook the first study of developmental psychology on innate communication forms. Not long after, physiologist William Preyer (1888) published a book on the abilities of an infant.

The 1900s saw many significant people dominating the developmental psychology field with their detailed theories of development: Sigmund Freud (1923, 1961), Jean Piaget (1928), Erik Erikson (1959), Lev Vygotsky (1978), John Bowlby (1958), and Albert Bandura (1977).

By the 1920s, the scope of developmental psychology had begun to include adult development and the aging process (Thompson, 2016).

In more recent years, it has broadened further to include prenatal development (Brandon et al., 2009). Developmental psychology is now understood to encompass the complete lifespan (Baltes et al., 2007).

Developmental Psychology Theories

Each of these models has contributed to the understanding of the process of human development and growth.

Furthermore, each theory and model focuses on different aspects of development: social, emotional, psychosexual, behavioral, attachment, social learning, and many more.

Here are some of the most popular models of development that have heavily contributed to the field of developmental psychology.

1. Bowlby’s attachment styles

The seminal work of psychologist John Bowlby (1958) showcased his interest in children’s social development. Bowlby (1969, 1973, 1980) developed the most famous theory of social development, known as attachment theory .

Bowlby (1969) hypothesized that the need to form attachments is innate, embedded in all humans for survival and essential for children’s development. This instinctive bond helps ensure that children are cared for by their parent or caregiver (Bowlby, 1969, 1973, 1980).

Bowlby’s original attachment work was developed further by one of his students, Mary Ainsworth. She proposed several attachment styles between the child and the caregiver (Ainsworth & Bell, 1970).

This theory clearly illustrates the importance of attachment styles to a child’s future development. Consistent and stable caregiving results in a secure attachment style (Ainsworth, Blehar, Waters, & Wall, 1978). In contrast, unstable and insecure caregiving results in several negative attachment styles: ambivalent, avoidant, or disorganized (Ainsworth & Bell, 1970; Main & Solomon, 1986).

Bowlby’s theory does not consider peer group influence or how it can shape children’s personality and development (Harris, 1998).

2. Piaget’s stage theory

Jean Piaget was a French psychologist highly interested in child development. He was interested in children’s thinking and how they acquire, construct, and use their knowledge (Piaget, 1951).

Piaget’s (1951) four-stage theory of cognitive development sequences a child’s intellectual development. According to this theory, all children move through these four stages of development in the same order (Simatwa, 2010).

The sensorimotor stage is from birth to two years old. Behaviors are triggered by sensory stimuli and limited to simple motor responses. If an object is removed from the child’s vision, they think it no longer exists (Piaget, 1936).

The pre-operational stage occurs between two and six years old. The child learns language but cannot mentally manipulate information or understand concrete logic (Wadsworth, 1971).

The concrete operational stage takes place from 7 to 11 years old. Children begin to think more logically about factual events. Abstract or hypothetical concepts are still difficult to understand in this stage (Wadsworth, 1971).

In the formal operational stage from 12 years to adulthood, abstract thought and skills arise (Piaget, 1936).

Piaget did not consider other factors that might affect these stages or a child’s progress through them. Biological maturation and interaction with the environment can determine the rate of cognitive development in children (Papalia & Feldman, 2011). Individual differences can also dictate a child’s progress (Berger, 2014).

3. Freud’s psychosexual development theory

One of the most influential developmental theories, which encompassed psychosexual stages of development, was developed by Austrian psychiatrist Sigmund Freud (Fisher & Greenberg, 1996).

Freud concluded that childhood experiences and unconscious desires influence behavior after witnessing his female patients experiencing physical symptoms and distress with no physical cause (Breuer & Freud, 1957).

According to Freud’s psychosexual theory, child development occurs in a series of stages, each focused on different pleasure areas of the body. During each stage, the child encounters conflicts, which play a significant role in development (Silverman, 2017).

Freud’s theory of psychosexual development includes the oral, anal, phallic, latent, and genital stages. His theory suggests that the energy of the libido is focused on these different erogenous zones at each specific stage (Silverman, 2017).

Freud concluded that the successful completion of each stage leads to healthy adult development. He also suggested that a failure to progress through a stage causes fixation and developmental difficulties, such as nail biting (oral fixation) or obsessive tidiness (anal fixation; Silverman, 2017).

Freud considered personality to be formed in childhood as a child passes through these stages. Criticisms of Freud’s theory of psychosexual development include its failure to consider that personality can change and grow over an entire lifetime. Freud believed that early experiences played the most significant role in shaping development (Silverman, 2017).

4. Bandura’s social learning theory

American psychologist Albert Bandura proposed the social learning theory (Bandura, Ross, & Ross, 1961). Bandura did not believe that classical or operant conditioning was enough to explain learned behavior because some behaviors of children are never reinforced (Bandura, 1986). He believed that children observe, imitate, and model the behaviors and reactions of others (Bandura, 1977).

Bandura suggested that observation is critical in learning. Further, the observation does not have to be of a live actor, such as in the Bobo doll experiment (Bandura, 1986). Bandura et al. (1961) considered that learning and modeling can also occur from listening to verbal instructions on behavior performance.

Bandura’s (1977) social theory posits that both environmental and cognitive factors interact to influence development.

Bandura’s developmental theory has been criticized for not considering biological factors or children’s autonomic nervous system responses (Kevin, 1995).

Overview of theories of development – Khan Academy

Developmental psychology has given rise to many debatable questions and research topics. Here are two of the most commonly discussed.

1. Nature vs nurture debate

One of the oldest debates in the field of developmental psychology has been between nature and nurture (Levitt, 2013).

Is human development a result of hereditary factors (genes), or is it influenced by the environment (school, family, relationships, peers, community, culture)?

The polarized position of developmental psychologists of the past has now changed. The nature/nurture question now concerns the relationship between the innateness of an attribute and the environmental effects on that attribute (Nesterak, 2015).

The field of epigenetics  describes how behavioral and environmental influences affect the expression of genes (Kubota, Miyake, & Hirasawa, 2012).

Many severe mental health disorders have a hereditary component. Yet, the environment and behavior, such as improved diet, reduced stress, physical activity, and a positive mindset, can determine whether this health condition is ever expressed (Śmigielski, Jagannath, Rössler, Walitza, & Grünblatt, 2020).

When considering classic models of developmental psychology, such as Piaget’s schema theory and Freud’s psychosexual theory, you’ll see that they both perceive development to be set in stone and unchangeable by the environment.

Contemporary developmental psychology theories take a different approach. They stress the importance of multiple levels of organization over the course of human development (Lomas, Hefferon, & Ivtzan, 2016).

2. Theory of mind

Theory of mind allows us to understand that others have different intentions, beliefs, desires, perceptions, behaviors, and emotions (American Psychological Association, 2020).

It was first identified by research by Premack and Woodruff (1978) and considered to be a natural developmental stage of progression for all children. Starting around the ages of four or five, children begin to think about the thoughts and feelings of others. This shows an emergence of the theory of mind (Wellman & Liu, 2004).

However, the ability of all individuals to achieve and maintain this critical skill at the same level is debatable.

Children diagnosed with autism exhibit a deficit in the theory of mind (Baron-Cohen, Leslie, & Frith, 1985).

Individuals with depression (psychotic and non-psychotic) are significantly impaired in theory of mind tasks (Wang, Wang, Chen, Zhu, & Wang, 2008).

People with social anxiety disorder have also been found to show less accuracy in decoding the mental states of others (Washburn, Wilson, Roes, Rnic, & Harkness, 2016).

Further research has shown that the theory of mind changes with aging. This suggests a developmental lifespan process for this concept (Meinhardt-Injac, Daum, & Meinhardt, 2020).

1. Little Albert

The small child who was the focus of the experiments of behavioral psychologists Watson and Rayner (1920) was referred to as ‘Little Albert.’ These experiments were essential landmarks in developmental psychology and showed how an emotionally stable child can be conditioned to develop a phobia.

Albert was exposed to several neutral stimuli including cotton wool, masks, a white rat, rabbit, monkey, and dog. Albert showed no initial fear to these stimuli.

When a loud noise was coupled with the initially neutral stimulus, Albert became very distressed and developed a phobia of the object, which extended to any similar object as well.

This experiment highlights the importance of environmental factors in the development of behaviors in children.

2. David Reimer

At the age of eight months, David Reimer lost his penis in a circumcision operation that went wrong. His worried parents consulted a psychologist, who advised them to raise David as a girl.

David’s young age meant he knew nothing about this. He went through the process of hormonal treatment and gender reassignment. At the age of 14, David found out the truth and wanted to reverse the gender reassignment process to become a boy again. He had always felt like a boy until this time, even though he was socialized and brought up as a girl (Colapinto, 2006).

Contemporary theories of developmental psychology often encompass a holistic approach and a more positive approach to development.

Positive psychology has intersected with developmental disciplines in areas such as parenting, education, youth, and aging (Lomas et al., 2016).

These paradigms can all be grouped together under the umbrella of positive developmental psychology. This fresh approach to development focuses on the wellbeing aspects of development, while systematically bringing them together (Lomas, et al., 2016).

  • Positive parenting is the approach to children’s wellbeing by focusing on the role of parents and caregivers (Latham, 1994).
  • Positive education looks at flourishing in the context of school (Seligman, Ernst, Gillham, Reivich, & Linkins, 2009).
  • Positive youth development is the productive and constructive focus on adolescence and early adulthood to enhance young people’s strengths and promote positive outcomes (Larson, 2000).
  • Positive aging , also known as healthy aging, focuses on the positivity of aging as a healthy, normal stage of life (Vaillant, 2004).

Much of the empirical and theoretical work connected to positive developmental psychology has been going on for years, even before the emergence of positive psychology itself (Lomas et al., 2016).

Developmental Psychology in Education

In the classroom, developmental psychology considers children’s psychological, emotional, and intellectual characteristics according to their developmental stage.

A report on the top 20 principles of psychology in the classroom, from pre-kindergarten to high school, was published by the American Psychological Association in 2015. The report also advised how teachers can respond to these principles in the classroom setting.

The top 5 principles and teacher responses are outlined in the table below.

Created by Experts. 100% Science-based.

Earlier developmental psychology models and theories were focused on specific areas, such as attachment, psychosexual, cognitive, and social learning. Although informative, they did not take in differing perspectives and were fixed paradigms.

We’ve now come to understand that development is not fixed. Individual differences take place in development, and the factors that can affect development are many. It is ever changing throughout life.

The modern-day approach to developmental psychology includes sub-fields of positive psychology. It brings these differing disciplines together to form an overarching positive developmental psychology paradigm.

Developmental psychology has helped us gain a considerable understanding of children’s motivations, social and emotional contexts, and their strengths and weaknesses.

This knowledge is essential for educators to create rich learning environments for students to help them develop positively and ultimately flourish to their full potential.

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

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.

Content Accuracy rating: 4

Most of the information is accurately written, there is some outdated references, for example: Many adults can remember being spanked as a child. This method of discipline continues to be endorsed by the majority of parents (Smith, 2012). It seems as though there may be more current research on parent's methods of discipline as this information is 10 years old. (page 223).

The content was current with the terminology used.

Easy to follow the references made in the chapters.

Each chapter covers the different stages of development and includes the theories of each stage with guided information for each age group.

The formatting of the book makes it reader friendly and easy to follow the content.

Very consistent from chapter to chapter.

Provided a lot of charts and references within each chapter.

Formatted and written concisely.

Included several different references to diversity in the chapters.

There was no glossary at the end of the book and there were no vignettes or reflective thinking scenarios in the chapters. Overall it was a well written book on child development which covered infancy through adolescents.

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. The authors have presented a valuable, well written book that will be an addition to our field. Their scholarly efforts are very apparent. All of this text earns high grades in my evaluation. My only criticism is, as mentioned above, is that there is not a glossary or index provided. All citations are embedded in the text.

The text can easily be divided into smaller reading sections or restructured to meet the needs of the professor.

The organization of the text adds to its consistency. However, some sections can be included in others decreasing the length of the text.

Interface issues were not visible.

The text appears to be free of grammatical errors.

While cultural differences are mentioned, more time can be given to helping teachers understand and create a culturally and ethnically focused curriculum.

The textbook provides a comprehensive summary of curriculum planing for preschool age children. However, very few chapters address infant/toddlers.

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 is a very comprehensive and detailed account of Child Growth and Development. The author leaves no stone unturned. It has the essential elements addressed in each of the developmental stages. Thoroughly researched and well thought out. The content covered was accurate, error-free and unbiased.

The content is very relevant to the subject of Child Growth and Development. It is comprehensive and thoroughly researched. The author has included a number of relevant subjects that highlight the three domains of developmental psychology, physical, cognitive and social emotional. Topics are included that help the student see the relevancy of the theories being discussed. Any necessary updates along the way will be very easy and straightforward to insert.

The text is easily understood. From the very beginning of this book, the author has given the reader a very clear message that does not overwhelm but pulls the reader in for more information. The very first chapter sets a tone for what is to come and entices the reader to learn more. Well organized and jargon appropriate for students in a Developmental Psychology class.

This book has all the ingredients necessary to address Child Growth and Development. Even at the very beginning of the book the backdrop is set for future discussions on the stages of development. Theorists are mentioned and embellished throughout the book. A very consistent and organized approach.

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. As mentioned previously the information is organized into building blocks as you move from one stage to the next.

The text does not contain any significant interface issued. There are no navigation problems. There is nothing that was detected that would distract or confuse the reader.

There are no grammatical errors that were identified.

This book was not culturally insensitive or offensive in any way.

This book is clearly a very comprehensive approach to Child Growth and Development. It contains all the essential ingredients that you would expect in a discussion on this subject. At the very outset this book went into detail on the principles of development and included all relevant theories. I was never left with wondering why certain topics were left out. This is undoubtedly a well written, organized and systematic approach to the subject.

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.

Developmental theorists use their research to generate philosophies on children’s development. They organize and interpret data based on a scheme to develop their theory. A theory refers to a systematic statement of principles related to observed phenomena and their relationship to each other. A theory of child development looks at the children's growth and behavior and interprets it. It suggests elements in the child's genetic makeup and the environmental conditions that influence development and behavior and how these elements are related. Many developmental theories offer insights about how the performance of individuals is stimulated, sustained, directed, and encouraged. Psychologists have established several developmental theories. Many different competing theories exist, some dealing with only limited domains of development, and are continuously revised. This article describes the developmental theories and their founders who have had the greatest influence on the fields of child development, early childhood education, and care. The following sections discuss some influences on the individuals’ development, such as theories, theorists, theoretical conceptions, and specific principles. It focuses on five theories that have had the most impact: maturationist, constructivist, behavioral, psychoanalytic, and ecological. Each theory offers interpretations on the meaning of children's development and behavior. Although the theories are clustered collectively into schools of thought, they differ within each school.

The author is grateful to Mary Jalongo for her expert editing and her keen eye for the smallest details.

Although Watson was the first to maintain explicitly that psychology was a natural science, behaviorism in both theory and practice had originated much earlier than 1913. Watson offered a vital incentive to behaviorism, but several others had started the process. He never stated to have created “behavioral psychology.” Some behaviorists consider him a model of the approach rather than an originator of behaviorism (Malone, 2014 ). Still, his presence has significantly influenced the status of present psychology and its development.

Internal Working Models of Attachment

Learning theory of attachment, john bowlby, attachment styles, jean piaget.

A schema is a knowledge structure that allows organisms to interpret and understand the world around them. Schemata are a method of organizing information that allows the brain to work more efficiently. Piaget’s theory of cognitive development put the concept at the forefront of cognitive science. Contemporary conceptions of schema evolved in the 1970s and 1980s.

Bowlby’s theory of attachment suggests that children come into the world biologically pre-programmed to form attachments with others, because this will help them to survive.

Bowlby’s maternal deprivation hypothesis suggests that continual attachment disruption between the infant and primary caregiver could result in long-term cognitive, social, and emotional difficulties for that infant.

An attachment style describes the way in which people relate to others, based on how secure they feel. Secure attachment is characterised by feelings of trust and safety in relationships. There appears to be continuity between early attachment styles and the quality of later adult romantic relationships.

Jean Piaget's theory of cognitive development suggests that children move through four different stages of intellectual development which reflect the increasing sophistication of children's thoughts. Child development is determined by biological maturation and interaction with the environment.

Frequent Asked Questions

What is developmental psychology?

Developmental psychology is a scientific approach which aims to explain how thinking, feeling, and behavior change throughout a person’s life. A significant proportion of theories within this discipline focus upon development during childhood, as this is the period during an individual’s lifespan when the most change occurs.

Learn More: Developmental Psychology

What is Freud’s psychosexual theory?

Sigmund Freud proposed that personality development in childhood takes place during five psychosexual stages, which are the oral, anal, phallic, latency, and genital stages.

During each stage, sexual energy (libido) is expressed in different ways and through different body parts.

What Is object permanence in Piaget’s theory?

Object permanence means knowing that an object still exists, even if it is hidden. It requires the ability to form a mental representation (i.e. a schema) of the object.

The attainment of object permanence generally signals the transition from the sensorimotor stage to the  preoperational stage of development .

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

In this chapter we looked at:

underlying principles of development

the five periods of development

three issues in development

Various methods of research

important theories that help us understand development

Next, we are going to be examining where we all started with conception, heredity, and prenatal development.

This article reviews the three major ways parents influence children: direct interaction, identification, and transmission of family stories. This essay summarizes some of the relevant empiric data in support of this claim and describes the operation of other mechanisms that also contribute to the child's development.

The profile of cognitive abilities, beliefs, ethical values, coping defenses, and salient emotional moods that characterizes each child at each developmental stage is the result of diverse influences operating in complex ways. Most students of human development agree that the most important determinants of the different profiles include 1) the inherited physiologic patterns that are called temperamental qualities, 2) parental practices and personality, 3) quality of schools attended, 4) relationships with peers, 5) ordinal position in the family, and, finally, 6) the historical era in which late childhood and early adolescence are spent. 1   Each of these factors exerts its major influence on only some components of the psychological profile and is usually most effective during particular age periods. For example, the quality of social relations with peers affects primarily the child's beliefs about his/her acceptability to others and has its major effect after school entrance. 2   By contrast, parental conversations with the child, and especially naming unfamiliar objects, affect the child's future verbal talents and have maximal effect during the first 6 years of life. 3  

Current discussions of the consequences of parental practices, whether in the media or in professional journals, favor one of two positions. One awards seminal power to parental factors; the other minimizes the family. The advocates of attachment theory, for example, propose that the relationships established between an infant and its caretakers during the first 2 years of life have a permanent effect on the child's future. 4   But Harris's recent book, The Nurture Assumption , makes the opposite claim by arguing that parents have little or no permanent influence on their child's future personality. 5   Although the attachment theorists take too strong a position, I side with a majority of developmental scholars who, in disagreement with Harris, believe that parents do affect their child's psychological growth. This article summarizes what most developmental scientists believe to be the major effects of parents on children.

It is important to appreciate, however, that some of these effects are difficult to quantify and, as a result, scholars working in this domain are caught between two opposing imperatives. On the one hand, they recognize that conclusions must be based on empiric evidence; if one does not have valid measurements, one should be cautious. On the other hand, investigators also recognize the error of awarding significance only to statements that rest on objective measurements. Because the current Zeitgeist is more positivistic than it was a half-century earlier, contemporary scientists usually have ignored important causative conditions that are subtle in their expression.

Parents can affect their children through at least three different mechanisms. The most obvious, and the one easiest both to imagine and to measure, involves the consequences of direct interactions with the child that could be recorded on film. For example, a mother praises a 3-year-old for eating properly, a father threatens the loss of a privilege because a child refuses to go to bed, a parent names an unfamiliar animal in a picture book. These everyday events that involve the rewarding of desirable actions, the punishment of undesired ones, and the transfer of knowledge from parent to child have a cumulative effect. Failure to discipline acts of disobedience and/or aggression is correlated with children's asocial behavior. 6   Display of interest in a young child's activities is correlated with greater levels of responsivity in the child. 7  

However, these first-order effects can have second-order consequences that appear later in life. A 7-year-old with a more extensive vocabulary than her peers, because her parents encouraged language development 5 years earlier, will master the tasks of the elementary grades more easily and, as a result, perceive herself as more competent than her peers. This belief is likely to embolden her to resist domination by others and, perhaps, motivate the initiation of unusually challenging tasks. The 7-year-old who was not chastised for aggressive behavior earlier or who had abusive or overly intrusive parents is likely to be aggressive with peers. As a result, these children provoke peer rejection and eventually come to question their acceptability to others. 8–10  

An emotional identification with either or both parents represents a second, quite different way in which the family affects children. By age 4 to 5 years, children believe, unconsciously, that some of the attributes of their parents are part of their own repertoire, even although this belief might have no objective basis. 11   A girl whose mother is afraid of storms and large animals is tempted to assume that she, too, is afraid of these dangerous events; a girl with a relatively fearless mother will come to the opposite conclusion. In addition, children share vicariously in some of the experiences that occur to the parents with whom they are identified. A boy whose father is popular with friends and relatives, for example, will find it easier to conclude that he, too, has qualities that make him acceptable to others.

The more distinctive the features shared between child and parent, the stronger the identification of the former with the latter. A father who is tall, thin, and has red hair and freckles will, other things equal, engender a stronger identification in a son with these four features than in a son who is short, chubby, brown-haired, and has no freckles. 1   That is why many members of minority groups that possess distinctive features have a strong identification; for example, whites in South Africa are more strongly identified with their ethnic group than whites in the United States.

Children also can identify with the class, ethnic, or religious group to which their family belongs and often feel an imperative to honor the identification. To fail to do so is to violate a principle of cognitive consistency between an ethical standard and an action and, as a result, to feel uncertain. Some adolescents for whom the group identification generates anxiety may attempt to minimize bases for the perceived similarity; hence, some Jews change their last name, some Mexicans try to lighten their skin, and some African-Americans straighten their hair.

The importance of identification for personality development means that the parents' personality, talents, and character, as they are perceived by the child, are of significance. When the content of parental rewards and punishments is in accord with the adult's persona as a role model, the content of adult socialization is potentiated. A child praised for her intellectual competence by parents who read books and display a curiosity about the world is more likely to value intellectual pursuits than one whose parents praise academic success but do not display any interest in intellectual competence in their personal lives. Children tend to honor what parents do rather than what they say.

The power of identification can be seen in the robust relation between the educational level of the parents, which is a good index of the social class of the family, and many psychological outcomes, including level of school achievement, frequency of aggressive behavior, and attitude toward authority. 12   The psychological differences between young adults born to college graduates, compared with those born to parents who never graduated from high school, cannot be explained completely as a result of direct interactions between parents and children. These psychological products also involve the child's identification with the family's social class. The features that define social class, as distinct from ethnicity, include place of residence, nature of the neighborhood, and material possessions. But because most parents do not remind their children of their social class and signs of family's social class position can be subtle, a child's discovery of the family's class is conceptually more difficult than discovery of his/her gender or ethnicity and usually is not articulated before 7 years of age.

The proportion of economically stressed families in a particular region will affect the strength of a child's identification. An awareness of those who are affluent and those who are not is most distinctive in societies like our own, where there is considerable variation in material wealth. No uniform psychological outcomes flow from absolute poverty, but many predictable outcomes flow from the belief that one's family is either advantaged or disadvantaged relative to others. Because many Americans believe that persistent hard work and intelligence are all that are needed to gain the wealth that has become, in this century, a defining feature of personal worth, class has a greater potential for shame in America than it does in many countries of the world. Ten-year-olds who identify with their relatively poor families are vulnerable to feelings of shame or psychological impotence if they wonder whether their family's status is attributable to the fact that their parents were either lazy or incompetent. The literary critic Frank Kermode, born to poor parents, once admitted to feeling like an outsider, “Looking the part while not being equal to it seems to be something I do rather well.” 13   Because identification with a poor family can generate anxiety, shame, or anger, it can represent a chronic psychological stress that might contribute to the generally poorer health of the economically disadvantaged. 14  

It has proven difficult to gather the objective evidence needed to affirm beyond doubt the truth of these statements about identification because of insufficiently sensitive procedures. However, some evidence does support this claim. In one unpublished study from my laboratory, white high school students, all with good grades, who came from either upper-middle or working-class families in the Boston area, came to a laboratory at Harvard University to be interviewed and evaluated for autonomic functioning. The working-class adolescents were more subdued in their interaction with the female examiner. In addition, the working-class youth had greater power in the lower-frequency band of the cardiac spectrum. This second fact implies greater sympathetic tone on the baroreceptor reflex, perhaps attributable to greater apprehension in a context that was symbolic of affluence and privilege.

A third mechanism of family influence is related to identification, but is more symbolic. Some parents tell their children stories about relatives —uncles, aunts, grandparents, cousins—who were, or are, especially accomplished in some domain. Perhaps an uncle made an important discovery, accumulated wealth, performed a courageous act, was a talented athlete or writer, or a respected public official. The child is likely to feel pride on hearing these stories because of the implication that if he or she is biologically related to this important family member, the child, too, must also possess some admirable characteristics. George Homans, an influential Harvard sociologist, noted in a memoir written shortly before his death that he coped with his childhood anxiety over poor school grades and unpopularity with peers by reminding himself that he could trace his pedigree back to John Adams. 15   Charles Darwin's description of his father glows with awe for his father's intelligence, sympathy, kindness, and business sense. 16   Darwin knew about the inheritance of psychological features through his acquaintance with animal breeders and may have felt that his cognitive talents were inevitable given his family's eminence.

Direct interactions, identification, and knowledge of the accomplishments of family members are three important ways in which families influence children. The first mechanism has its greatest effect on intellectual development and character traits, especially the control of aggression and motivation for achievement. The second and third mechanisms, identification and family myths, have a greater influence on the child's confidence or doubt about his/her talent and, therefore, on the child's expectation of future success or failure.

A persuasive source of support for the significance of family experience is found in follow-up studies of young children who suffered serious privation, usually the result of war, and were later adopted by nurturant families. Many of the orphans produced by World War II and the Korean conflict, who had extremely fragile bonds to any caretaker in their early years, appeared to develop well after adoption by loving foster parents. 17   ,18   More recently, a group of children who had spent the first year in depriving orphanages in Romania were adopted by nurturant British parents. When they arrived in London, they were emaciated and psychologically retarded, as one would expect, given their harsh experience. However, when they were evaluated several years later, after adoption by middle-class parents, a majority, although not all, were similar in their intellectual profile to the average British child (Michael Rutter, personal communication, 1998).

A study of 13 624 families living in 10 different cities provides a particularly persuasive demonstration of the importance of the family. The children, who were observed as infants and again at 3 years of age, had experienced varied forms of early care. Some were in day care centers, some were in family day care, and some were raised only at home. The form of care outside the home had little effect on the prevalence of problems with self-control, compliance, and asocial behavior; variation among the families was a critical determinant of differences in these psychological traits. 19  

Although empiric data affirm that parental behaviors and personality traits influence the child's talents, motivation, academic performance, and social behavior, 20   their influence is part of a larger web of conditions that includes inherited temperamental biases, ordinal position, social class, ethnicity, quality of peer friendships, and the historical era in which adolescence is spent. The importance of temperament is seen in a longitudinal study of a large group of healthy children. Approximately 20% of these healthy infants inherited a temperament that was revealed at 4 months of age in vigorous levels of motor activity and irritability to unfamiliar stimulation. 21   Approximately one third of these infants, called high reactive, were shy and fearful to unfamiliar people and settings during the preschool years, and approximately one fourth were likely to develop anxious symptoms when they were 7 years old. 22   Although only 20% of the high reactive infants were consistently shy and fearful from 14 months to 8 years of age, it was rare for a high reactive infant to become a consistently bold, extroverted child.

The influence of ordinal position is affirmed by the fact that, controlling for social class, first-born children obtain better grades and are more often high school valedictorians than later born children. 23  

The influence of historical era is revealed in a study of the cohort of Americans that was between 10 and 20 years of age during the economic Depression in America from 1930 to 1940. A large proportion of these American adolescents, who are now in their 7th decade, saved more money than the generation before or after and conducted their lives with a gnawing concern over financial loss. 24  

The protest against the Vietnam War at the end of the 1960s also affected large numbers of privileged adolescents who turned against the values of established authority. College students seized administration buildings or shared sexual partners in unheated communal homes. High school youth defiantly left their classrooms to protest the war, and they got away with it. It is heady for a 16-year-old to defy the rules of authority and escape punishment. For many youth, such experiences eroded a tendency to worry about coming to work at 10:00 in the morning instead of 9 and leaving at 4 instead of 5. Many of these middle-class youth thumbed their noses at authority because they happened to be born during a brief period when segments of American society were uncertain as to which actions were legitimate. When history tears a hole in the fabric of consensual assumptions, the mind flies through it into a space free of hoary myth to invent a new conception of self, ethics, and society.

The influence of these extrafamilial factors suggests that it is more accurate to state that parental qualities contribute to a child's psychological profile, rather than to conclude that family conditions determine a particular outcome. An infant's secure attachment to a parent does not guarantee a benevolent outcome or protect a child against psychological problems later in life, but the secure attachment probably constrains the likelihood of producing an adult who is homeless. Physicians are familiar with this form of restrained conclusion. Chronic middle ear infection during the first 2 years of life does not always lead to language delay, but it can make a small contribution to that phenomenon.

Eleanor Maccoby, a colleague and a distinguished developmental psychologist, wrote that the contribution of parental practices to children's personality cannot be viewed in isolation. Each parental behavior or parental personality trait is part of a complex system that in some respects is unique to each parent–child relationship. 25  

This conclusion is not different in substance from most generalizations about complex natural phenomena, including the appearance or extinction of a species or the duration of an infectious epidemic. The proper conceptual posture is restraint on shrill dogma that claims either that the family is without significance or that it represents the only conditions that matter.

1 What is child psychology?

How are children’s lives changing and what role do child psychologists have in supporting children? Child psychology is a broad area, covering how people change as they grow up from birth through to adolescence and trying to explain how these important changes occur – are 3-year-olds, 7-year-olds and teenagers different just because of their experiences of the world, or what role is played by biological changes within the individual?

Because child psychology is so vast and tries to answer so many questions, researchers and practitioners often separate development into specific areas. Broadly, these tend to map onto children’s physical, cognitive (thinking, learning, memory, etc.) and social/emotional development. Child psychologists attempt to make sense of every aspect of child development, including how children learn, think, interact and respond emotionally to those around them, make friends, understand emotions and their own developing personalities, temperaments and skills.

Children typically reach developmental ‘milestones’. These milestones reflect abilities, such as walking and talking, that are achieved by most children at similar ages. Among other things, we are interested in trying to explain how children reach these milestones and how individual, social and cultural factors may influence how we develop.

Psychologists also specialise in different areas of interest: while some focus on supporting children in school settings (educational psychologists) others focus on supporting children with atypical development (clinical psychologists).

Activity 1 What do child psychologists do?

In this audio sequence Nathalia Gjersoe, a lecturer in developmental psychology at The Open University, looks at the roles and work of three developmental psychologists, all of whom are concerned with children. Duncan Gillard (an educational psychologist), Silvana Mengoni (a researcher) and Catriona Havard (a forensic psychologist) all give their views about child psychology. Listen to the audio and think about the questions that follow.

  • Tips for Students

Are you looking for a developmental psychology topic for a psychology paper , experiment, or science fair project? Topics you might pick can range from prenatal development to health during the final stages of life.

Developmental psychology is a broad topic that involves studying how people grow and change throughout their whole lifetime. Topics don't just include physical growth but also the emotional, cognitive, and social development that people experience at different stages of their lives.

At a Glance

The following are just a few different topics that might help inspire you. Remember, these are just ideas to help you get started. You might opt to explore one of these areas, or you might think of a related question that interests you as well.

Developmental Psychology Topics on Childhood

  • Could packaging nutritious foods in visually appealing ways encourage children to make healthier food choices?
  • Do children who listen to music while studying perform better or worse on exams?
  • Do students who eat breakfast perform better in school than those who do not eat breakfast?
  • Does birth order have an impact on procrastination ? Are first-borns less likely to procrastinate? Are last-borns more likely to put off tasks until the last minute?
  • Does teaching infants sign language help or hinder the language acquisition process?
  • How do parenting styles impact a child's level of physical activity? Are children raised by parents with permissive or uninvolved parents less active than those raised by parents with authoritative or authoritarian styles?
  • How does bullying impact student achievement? Are bullied students more likely to have worse grades than their non-bullied peers?
  • Which type of reinforcement works best for getting students to complete their homework: a tangible reward (such as a piece of candy) or social reinforcement (such as offering praise when homework is completed on time)?

Developmental Psychology Topics on Adolescence

  • What factors tend to influence the onset of depression in teens and young adults?
  • How do peer relationships influence identity formation during adolescence and young adulthood?
  • What impact do parent-child relationships have in predicting substance use among teens and young adults?

  • How does technology use during adolescence influence social and emotional development?
  • How does social media use influence body image among teens?
  • What factors contribute to success during the transition from the teen years to early adulthood?
  • How do cultural differences impact different aspects of adolescent development?

Developmental Psychology Topics on Adulthood

  • Are older adults who rate high in self-efficacy more likely to have a better memory than those with low self-efficacy?
  • Do the limits of short-term memory change as we age? How do the limits of short-term memory compare at ages, 15, 25, 45, and 65?
  • Do mental games such as word searches, Sudoku, and word matching help elderly adults keep their cognitive skills sharp?
  • How do explanations for the behavior of others change as we age? Are younger adults more likely to blame internal factors for events and older adults more likely to blame external variables?

Choosing Developmental Psychology Topics

Developmental psychology is a huge and diverse subject, so picking a topic isn't always easy. Some tips that can help you choose a good developmental psychology topic include:

  • Focus on a specific topic : Make sure that your topic isn't too broad to avoid getting overwhelmed by the amount of information available
  • Have a clear question or hypothesis : Your research question should be focused and clearly defined
  • Do some background research : Spend some time reviewing the existing literature to get a better idea about what you want to cover with your topic
  • Consider developmental theories : You might consider analyzing your topic through the lens of a particular theory of developmental psychology
  • Check out recent research : Use research databases to find the most recently published research on your topic

Before you start working on any paper, experiment, or science project, the first thing you need to do is understand the rules your instructor has established for the assignment.

Also, be sure to check the official guidelines given by your teacher. If you are not sure about these guidelines, ask your instructor if there are any specific requirements before you get started on your research .

If you are going to actually conduct an experiment , you need to present your idea to your instructor to gain their permission before going forward. In some cases, you might have to also present your plan to your school's Institutional Review Board.

Tips for Researching Developmental Psychology Topics

After you have gotten to move forward with your chosen topic, the next step is to do some background research. This step is essential! If you are writing a paper, the information you find will make up your literature review.

If you are performing an experiment, it will provide background information for the introduction of your lab report . For a psychology science project, this research will help you in your presentation and can help you decide how to best approach your own experiment.

What This Means For You

Choosing a topic for a developmental psychology experiment, paper, or project can be tough! The ideas above can be a great place to start, but you might also consider questions you've had about your own life. Once you have a general idea for your topic, narrow it down, do some background research and talk to your instructor.

Early Childhood

Reviewed by Psychology Today Staff

During this period, roughly covering ages 3 to 5, a child’s personality, interests, and social orientation begin to come into focus, but parents should keep in mind that personality traits, personal preferences, and intellectual and academic ability are not “locked in” for life during this (or any other) stage. At this age, many children will have their first formal learning experiences—including learning to socialize with others without a parent present. In some cases, parents may have to deal with a child’s aggression toward others, or with helping them deal with other children’s aggression toward them. Caregivers can take advantage of children’s openness to learning at this age by continuing to read to them often and conversing with them on a wide range of topics while introducing new words and ideas to them.

  • What are the key milestones of early childhood development?
  • Is personality locked in during early childhood?
  • How do young children learn to share?
  • How much play time do kids need?
  • Why can young children sometimes be aggressive, or even mean?
  • Why do some tantrums last so long?
  • What makes some children shy?
  • What do children learn from picture books?
  • How does conversation help children’s brains develop?

According to the Centers for Disease Control and Prevention and the American Academy of Pediatrics, by the end of early childhood, at about age 5, children can be expected to display most of the following social and cognitive skills, although each child develops differently and may achieve some milestones earlier or later than others and still be considered to be experiencing healthy development:

Social Development

  • Prefers playing with others to playing alone.
  • Wants to please friends, and be like their friends.
  • More likely to understand and follow rules.
  • Likes to sing, dance, and act.
  • Is aware of gender.
  • Can tell what’s real and what’s make-believe.
  • Displays, and seeks, more independence in and out of the home.
  • Is sometimes demanding and sometimes very cooperative.

Cognitive Development and Communication Skills

  • Speaks clearly.
  • Tells a simple story using full sentences.
  • Uses future tense; for example, “Grandma will be here.”
  • Can say their name and address.
  • Can count 10 or more things.
  • Can draw a person with at least 6 body parts.
  • Can print many letters or numbers, and reproduce geometric shapes.
  • Knows about things used every day, like money and food.

No. Early childhood is a crucial developmental stage, but the idea that personality is set in stone at this age is easily disproved. Children raised in abusive homes, for example, can grow to be emotionally healthy. And adults who have long struggled with anxiety can learn to change through psychotherapy, a field built on the idea that we can change if we really desire to do so. Parents should still do all they can to create a stable emotional environment and foster their children’s intelligence and social skills, which can benefit them throughout their lives. But biological and environmental factors beyond a parent’s control can negatively affect a child, and so parents also should not imagine that every struggle a child ever faces can be tracked to mistakes they made in early childhood.

Preschoolers are often selfish , holding onto coveted resources whenever they have the opportunity and resisting pleas to share, even though they know it’s the right thing to do. It doesn’t mean young children are jerks; other research shows that they are highly empathetic, quickly offering comfort to those in distress. Sharing toys, however, or understanding the concept of giving to help others in need may require parental guidance. Fortunately, the evidence is clear that kids can learn to share and that, like adults, helping others makes them feel good, just as it does for adults. Parents who can explain the benefits of sharing, successfully model the behavior, and convey their good feelings at being generous, are most likely to help their children acquire the habit of sharing.

Children need much more than they usually get. Studies have found that children today spend less time engaged in creative or free play , especially outside, than they did in the past, for reasons including increased time spent on digital media, parental or household routines that don’t allow for free play, and heightened concerns over safety and a decreased willingness to let children play outside unsupervised. As a result, some advocates argue, kids may be more sedentary, less creative, and less independent, than they could be.

Children act aggressively at an early age: Kids may hit, bite, push, or kick before they turn 18 months old. In early childhood, verbal aggression like teasing and name-calling become more common. Toddlers typically become aggressive because they are angry or afraid but at older ages, when children understand how their actions can affect someone else, aggression becomes more concerning. It’s at this age that bullying behavior begins.

Many bullies, rather than having emotional problems, have high levels of emotional understanding, but may have learned from other experiences that people are generally hostile, and so that not only should they react aggressively to perceived offenses, but that aggression is a reasonable response. Parents and teachers who can take steps to promote empathy can help young children learn to be more understanding of others and to approach social interactions in a healthier way.

Tantrums can be enormously distressing for parents, especially because of their apparent lack of internal logic: Small issues can spark explosions of anger that often continue long after the initial issue has been resolved. It’s important to understand the difference between a tantrum’s trigger and the factors that keep it going. Environmental issues can play a role: A crowded space, for example, especially one in which a child feels on display, can drive their stress further upward. A parent’s response to a tantrum can also extend it, because stress is contagious. When a child misbehaves, and a parent shouts, the child can become even more stressed, and both can become inflexible, fueling a lengthy tantrum cycle. When parents can recognize this cycle, they can step out of it, helping the child calm down more quickly, and, if necessary, they can further address the behavior later.

Signs of an outgoing or reserved personality can be seen, some research suggests, in children as young as four months: Those who showed the most emotional distress tended to be most likely to develop social anxiety later. But normal shyness in a child is not necessarily a sign of a concern. Temperaments often change as kids get older, and, besides, many people take a little time to warm up to new people and situations. In the meantime, parents can help highly sensitive or anxious children thrive by letting them adjust to new things at their own pace and understanding their internal anxiety, which is often closely tied to a tendency for feeling guilty, by only gently reprimanding them when they break a rule.

More than 60 percent of parents of young children read to them every day, and the benefits are clear, predicting future interest in reading as well as academic achievement. When parents read aloud to their children , they expose them to a range of words and turns of phrase that may not be part of their normal everyday conversations. Kids can learn sophisticated content as well, as a study of their retention of key concepts from books on animal camouflage and evolution showed. Above all, though, children find comfort from hearing their parents’ voices read to them, and thrive on the bonding that reading time enables.

A child’s early exposure to language is at the core of their development, predicting language skills, cognitive ability, and academic achievement. Recent research emphasizes the importance of early conversation in the development of language structures in the brain: The more conversation kids experienced, the stronger the connections between regions of the brain responsible for speech production and comprehension. These findings are part of a body of research suggesting that rich and complex conversational turns are at least as important to language development as the raw number of words a child hears.
