Top 100 Experimental Research Topics for School & College Students: Are you a student looking for inspiration for your next research project? Research is a vital aspect of your educational journey, and choosing the right topic is often the first step to success. Whether you’re in school or college, finding a compelling experimental research topic can be a daunting task. But fear not! We’ve compiled a list of the top 100 experimental research topics to ignite your curiosity and help you embark on an exciting research journey.

What is Experimental Research?

Experimental research is a research approach that entails the deliberate manipulation of one or more independent variables to assess their impact on one or more dependent variables. It is widely regarded as the “gold standard” of research methodologies due to its capacity to establish causal relationships between variables.

Typically, experimental research designs involve the creation of two distinct groups: the experimental group and the control group. The experimental group is exposed to the independent variable, while the control group is not. Subsequently, the researcher compares the outcomes of these two groups to identify any disparities.

Two primary categories of experimental research designs exist: true experiments and quasi-experiments. True experiments employ random assignment of participants to the experimental and control groups, ensuring initial equivalency between the groups and minimizing alternative explanations for observed differences.

Conversely, quasi-experiments lack random assignment, potentially introducing disparities between the experimental and control groups at the outset, which may confound the results. Nevertheless, quasi-experiments can still be valuable in studying cause-and-effect relationships, particularly when random assignment is impractical or ethically challenging.

Experimental research finds applications across diverse fields such as science, medicine, education, and business. It serves as a potent tool for comprehending how various factors influence outcomes and for developing novel products and interventions.

Consider the following examples of experimental research :

A scientist aims to assess a new drug’s effectiveness in treating high blood pressure. Participants are randomly assigned to receive either the new drug or a placebo. After several weeks, their blood pressure is measured, and the results between the two groups are compared.

A teacher seeks to investigate the impact of various teaching methods on student achievement. Students are randomly allocated to different classrooms, each utilizing a distinct teaching method. At the end of the semester, the students’ test scores are compared to identify the most effective teaching method.

A marketing manager intends to evaluate the influence of a new advertising campaign on product sales. A random sample of customers is chosen and assigned to either view the new advertising campaign or not. After several weeks, sales data from the two groups are compared to determine the campaign’s effectiveness.

Major Types of Experimental Research Design

There are three main types of experimental research designs:

1. Pre-experimental research designs

Pre-experimental research designs are the simplest type of experimental design. They do not involve random assignment, and the researcher typically only tests one group of participants. Pre-experimental research designs are often used to generate preliminary data or to explore new research questions. However, they are not considered to be as rigorous as other types of experimental designs because they are more prone to confounding variables.

Here are some examples of pre-experimental research designs:

  • One-shot case study design: The researcher tests a single group of participants after they have been exposed to the independent variable.
  • One-group pretest-posttest design: The researcher tests a single group of participants before and after they have been exposed to the independent variable.
  • Static-group comparison design: The researcher compares two groups of participants, one of which has been exposed to the independent variable and the other of which has not.

2. Quasi-experimental research designs

Quasi-experimental research designs are more rigorous than pre-experimental research designs because they involve some form of control group. However, they do not involve random assignment. Quasi-experimental research designs are often used in situations where random assignment is not feasible or ethical.

Here are some examples of quasi-experimental research designs:

  • Non-equivalent control group design: The researcher compares two groups of participants, one of which has been exposed to the independent variable and the other of which has not. The two groups are not randomly assigned, but the researcher tries to match them on relevant characteristics to reduce the risk of confounding variables.
  • Time series design: The researcher tests a single group of participants multiple times over time, both before and after they have been exposed to the independent variable.
  • Interrupted time series design: The researcher tests a single group of participants multiple times over time, both before and after they have been exposed to the independent variable. However, there is an interruption in the time series, such as a change in policy or practice, that may affect the dependent variable.

3. True experimental research designs

True experimental research designs are the most rigorous type of experimental design. They involve random assignment and a control group. True experimental research designs are considered to be the best way to establish cause-and-effect relationships between variables.

Here are some examples of true experimental research designs:

  • Randomized controlled trial (RCT): The researcher randomly assigns participants to either the experimental group or the control group. The experimental group is exposed to the independent variable, while the control group is not. The researcher then compares the outcomes of the two groups to see if there is a difference.
  • Posttest-only control group design: The researcher randomly assigns participants to either the experimental group or the control group. The experimental group is exposed to the independent variable, while the control group is not. The researcher then measures the dependent variable in both groups after the experiment is complete.
  • Solomon four-group design: This design is similar to the posttest-only control group design, but it also includes two additional groups: a pretest-posttest experimental group and a pretest-posttest control group. This allows the researcher to control for the effects of testing.

Experimental research is a powerful tool for understanding the world around us and developing new ways to improve our lives. By understanding the different types of experimental research designs, we can better evaluate the quality of research and make informed decisions about the findings.

Elements of Experimental Research

Experimental research typically comprises several essential elements that help structure and conduct a rigorous scientific investigation. These elements are crucial for designing, executing, and analyzing experiments effectively. Here are the key elements of experimental research:

  • Research Question or Hypothesis : Every experiment begins with a clear research question or a testable hypothesis. This question or hypothesis specifies what the researcher aims to investigate or the relationship they seek to explore.
  • Independent Variable : The independent variable is the factor that the researcher intentionally manipulates or varies in the experiment. It is the presumed cause and is under the researcher’s control. In some cases, there may be more than one independent variable.
  • Dependent Variable : The dependent variable is the outcome or response that the researcher measures or observes. It is the variable that may be influenced by changes in the independent variable. The dependent variable is what researchers are trying to understand or explain.
  • Experimental and Control Groups : To assess the impact of the independent variable, participants or subjects are typically divided into at least two groups: the experimental group and the control group. The experimental group is exposed to the independent variable, while the control group is not. This comparison helps determine whether any observed effects are due to the manipulation of the independent variable.
  • Random Assignment : In true experimental designs, participants are randomly assigned to the experimental and control groups. Random assignment helps ensure that the groups are comparable and minimizes bias, increasing the internal validity of the experiment.
  • Controlled Conditions : Experimental research strives to control and minimize the influence of extraneous variables, which are factors other than the independent variable that could affect the results. This control helps isolate the effects of the independent variable.
  • Experimental Procedure : Researchers outline the specific steps and procedures that participants will undergo during the experiment. This includes how the independent variable will be manipulated, how data will be collected, and the sequence of events.
  • Data Collection : Data collection involves gathering information about the dependent variable’s responses or outcomes. This is typically done through measurements, observations, surveys, or other data collection methods.
  • Data Analysis : After data collection, researchers analyze the collected data using statistical methods to determine whether there are significant differences or relationships between groups. This analysis helps draw conclusions about the impact of the independent variable on the dependent variable.
  • Replication : To enhance the reliability of experimental findings, replication involves repeating the experiment under similar conditions to see if the results can be consistently reproduced.
  • Ethical Considerations : Researchers must adhere to ethical principles when conducting experiments involving human or animal subjects. This includes obtaining informed consent, ensuring participant well-being, and minimizing harm.
  • Reporting and Communication : Researchers communicate their findings by writing research papers or reports that describe the experiment, its methods, results, and conclusions. This enables other scientists to assess and build upon the research.

These elements collectively form the foundation of experimental research, allowing researchers to systematically investigate and establish cause-and-effect relationships between variables in a controlled and methodical manner.

feature_pencilpaper

One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

113 Good Research Paper Topics

Below are 113 good research topics to help you get you started on your paper. We've organized them into ten categories to make it easier to find the type of research paper topics you're looking for.

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.

Often, unexpected results can lead to new insights and directions for future research. It’s important to accurately report your findings, whether they support your hypothesis or not, and discuss potential reasons for the outcome in your conclusion.

How can I ensure my experimental research is ethically sound?

To ensure your experimental research is ethically sound, you need to consider informed consent, confidentiality, and avoidance of harm. If you’re working with human subjects, they need to be aware of the study’s purpose, potential risks, and their right to withdraw. You should also safeguard participants’ information and protect their identities.

What are some key steps in conducting experimental research?

Key steps in conducting experimental research include formulating a clear, testable hypothesis, designing and conducting the experiment, systematically collecting data, analyzing this data using suitable methods, and interpreting the results. It’s also crucial to consider ethical aspects throughout the research process.

Psychology Experiment Ideas

Sharing is caring!

Quick Ideas | Experiment Ideas | Designing Your Experiment | Types of Research

If you are taking a psychology class, you might at some point be asked to design an imaginary experiment or perform an experiment or study. The idea you ultimately choose to use for your psychology experiment may depend upon the number of participants you can find, the time constraints of your project, and limitations in the materials available to you.

Consider these factors before deciding which psychology experiment idea might work for your project.

This article discusses some ideas you might try if you need to perform a psychology experiment or study.

Table of Contents

A Quick List of Experiment Ideas

If you are looking for a quick experiment idea that would be easy to tackle, the following might be some research questions you want to explore:

  • How many items can people hold in short-term memory ?
  • Are people with a Type A personality more stressed than those with a Type B personality?
  • Does listening to upbeat music increase heart rate?
  • Are men or women better at detecting emotions ?
  • Are women or men more likely to experience imposter syndrome ?
  • Will students conform if others in the group all share an opinion that is different from their own?
  • Do people’s heartbeat or breathing rates change in response to certain colors?
  • How much do people rely on nonverbal communication to convey information in a conversation?
  • Do people who score higher on measures of emotional intelligence also score higher on measures of overall well-being?
  • Do more successful people share certain personality traits ?

Most of the following ideas are easily conducted with a small group of participants, who may likely be your classmates. Some of the psychology experiment or study ideas you might want to explore:

Sleep and Short-Term Memory

Does sleep deprivation have an impact on short-term memory ?

Ask participants how much sleep they got the night before and then conduct a task to test short-term memory for items on a list.

Social Media and Mental Health

Is social media usage linked to anxiety or depression?

Ask participants about how many hours a week they use social media sites and then have them complete a depression and anxiety assessment.

Procrastination and Stress

How does procrastination impact student stress levels?

Ask participants about how frequently they procrastinate on their homework and then have them complete an assessment looking at their current stress levels.

Caffeine and Cognition

How does caffeine impact performance on a Stroop test?

In the Stroop test , participants are asked to tell the color of a word, rather than just reading the word. Have a control group consume no caffeine and then complete a Stroop test, and then have an experimental group consume caffeine before completing the same test. Compare results.

Color and Memory

Does the color of text have any impact on memory?

Randomly assign participants to two groups. Have one group memorize words written in black ink for two minutes. Have the second group memorize the same words for the same amount of time, but instead written in red ink. Compare the results.

Weight Bias

How does weight bias influence how people are judged by others?

Find pictures of models in a magazine who look similar, including similar hair and clothing, but who differ in terms of weight. Have participants look at the two models and then ask them to identify which one they think is smarter, wealthier, kinder, and healthier.

Assess how each model was rated and how weight bias may have influenced how they were described by participants.

Music and Exercise

Does music have an effect on how hard people work out?

Have people listen to different styles of music while jogging on a treadmill and measure their walking speed, heart rate, and workout length.

The Halo Effect

How does the Halo Effect influence how people see others?

Show participants pictures of people and ask them to rate the photos in terms of how attractive, kind, intelligent, helpful, and successful the people in the images are.

How does the attractiveness of the person in the photo correlate to how participants rate other qualities? Are attractive people more likely to be perceived as kind, funny, and intelligent?

Eyewitness Testimony

How reliable is eyewitness testimony?

Have participants view video footage of a car crash. Ask some participants to describe how fast the cars were going when they “hit into” each other. Ask other participants to describe how fast the cars were going when they “smashed into” each other.

Give the participants a memory test a few days later and ask them to recall if they saw any broken glass at the accident scene. Compare to see if those in the “smashed into” condition were more likely to report seeing broken glass than those in the “hit into” group.

The experiment is a good illustration of how easily false memories can be triggered.

Simple Psychology Experiment Ideas

If you are looking for a relatively simple psychology experiment idea, here are a few options you might consider.

The Stroop Effect

This classic experiment involves presenting participants with words printed in different colors and asking them to name the color of the ink rather than read the word. Students can manipulate the congruency of the word and the color to test the Stroop effect.

Memory Recall

Students can design a simple experiment to test memory recall by presenting participants with a list of items to remember and then asking them to recall the items after a delay. Students can manipulate the length of the delay or the type of encoding strategy used to see the effect on recall.

Social Conformity

Students can test social conformity by presenting participants with a simple task and manipulating the responses of confederates to see if the participant conforms to the group response.

Selective Attention

Students can design an experiment to test selective attention by presenting participants with a video or audio stimulus and manipulating the presence or absence of a distracting stimulus to see the effect on attention.

Implicit Bias

Students can test implicit bias by presenting participants with a series of words or images and measuring their response time to categorize the stimuli into different categories.

The Primacy/Recency Effect

Students can test the primacy /recency effect by presenting participants with a list of items to remember and manipulating the order of the items to see the effect on recall.

Sleep Deprivation

Students can test the effect of sleep deprivation on cognitive performance by comparing the performance of participants who have had a full night’s sleep to those who have been deprived of sleep.

These are just a few examples of simple psychology experiment ideas for students. The specific experiment will depend on the research question and resources available.

Elements of a Good Psychology Experiment

Finding psychology experiment ideas is not necessarily difficult, but finding a good experimental or study topic that is right for your needs can be a little tough. You need to find something that meets the guidelines and, perhaps most importantly, is approved by your instructor.

Requirements may vary, but you need to ensure that your experiment, study, or survey is:

  • Easy to set up and carry out
  • Easy to find participants willing to take part
  • Free of any ethical concerns

In some cases, you may need to present your idea to your school’s institutional review board before you begin to obtain permission to work with human participants.

Consider Your Own Interests

At some point in your life, you have likely pondered why people behave in certain ways. Or wondered why certain things seem to always happen. Your own interests can be a rich source of ideas for your psychology experiments.

As you are trying to come up with a topic or hypothesis, try focusing on the subjects that fascinate you the most. If you have a particular interest in a topic, look for ideas that answer questions about the topic that you and others may have. Examples of topics you might choose to explore include:

  • Development
  • Personality
  • Social behavior

This can be a fun opportunity to investigate something that appeals to your interests.

Read About Classic Experiments

Sometimes reviewing classic psychological experiments that have been done in the past can give you great ideas for your own psychology experiments. For example, the false memory experiment above is inspired by the classic memory study conducted by Elizabeth Loftus.

Textbooks can be a great place to start looking for topics, but you might want to expand your search to research journals. When you find a study that sparks your interest, read through the discussion section. Researchers will often indicate ideas for future directions that research could take.

Ask Your Instructor

Your professor or instructor is often the best person to consult for advice right from the start.

In most cases, you will probably receive fairly detailed instructions about your assignment. This may include information about the sort of topic you can choose or perhaps the type of experiment or study on which you should focus.

If your instructor does not assign a specific subject area to explore, it is still a great idea to talk about your ideas and get feedback before you get too invested in your topic idea. You will need your teacher’s permission to proceed with your experiment anyway, so now is a great time to open a dialogue and get some good critical feedback.

Experiments vs. Other Types of Research

One thing to note, many of the ideas found here are actually examples of surveys or correlational studies .

For something to qualify as a tru e experiment, there must be manipulation of an independent variable .

For many students, conducting an actual experiment may be outside the scope of their project or may not be permitted by their instructor, school, or institutional review board.

If your assignment or project requires you to conduct a true experiment that involves controlling and manipulating an independent variable, you will need to take care to choose a topic that will work within the guidelines of your assignment.

Types of Psychology Experiments

There are many different types of psychology experiments that students could perform. Examples of psychological research methods you might use include:

Correlational Study

This type of study examines the relationship between two variables. Students could collect data on two variables of interest, such as stress and academic performance, and see if there is a correlation between the two.

Experimental Study

In an experimental study, students manipulate one variable and observe the effect on another variable. For example, students could manipulate the type of music participants listen to and observe its effect on their mood.

Observational Study

Observational studies involve observing behavior in a natural setting . Students could observe how people interact in a public space and analyze the patterns they see.

Survey Study

Students could design a survey to collect data on a specific topic, such as attitudes toward social media, and analyze the results.

A case study involves in-depth analysis of a single individual or group. Students could conduct a case study of a person with a particular disorder, such as anxiety or depression, and examine their experiences and treatment options.

Quasi-Experimental Study

Quasi-experimental studies are similar to experimental studies, but participants are not randomly assigned to groups. Students could investigate the effects of a treatment or intervention on a particular group, such as a classroom of students who receive a new teaching method.

Longitudinal Study

Longitudinal studies involve following participants over an extended period of time. Students could conduct a longitudinal study on the development of language skills in children or the effects of aging on cognitive abilities.

These are just a few examples of the many different types of psychology experiments that students could perform. The specific type of experiment will depend on the research question and the resources available.

Steps for Doing a Psychology Experiment

When conducting a psychology experiment, students should follow several important steps. Here is a general outline of the process:

Define the Research Question

Before conducting an experiment, students should define the research question they are trying to answer. This will help them to focus their study and determine the variables they need to manipulate and measure.

Develop a Hypothesis

Based on the research question, students should develop a hypothesis that predicts the experiment’s outcome. The hypothesis should be testable and measurable.

Select Participants

Students should select participants who meet the criteria for the study. Participants should be informed about the study and give informed consent to participate.

Design the Experiment

Students should design the experiment to test their hypothesis. This includes selecting the appropriate variables, creating a plan for manipulating and measuring them, and determining the appropriate control conditions.

Collect Data

Once the experiment is designed, students should collect data by following the procedures they have developed. They should record all data accurately and completely.

Analyze the Data

After collecting the data, students should analyze it to determine if their hypothesis was supported or not. They can use statistical analyses to determine if there are significant differences between groups or if there are correlations between variables.

Interpret the Results

Based on the analysis, students should interpret the results and draw conclusions about their hypothesis. They should consider the study’s limitations and their findings’ implications.

Report the Results

Finally, students should report the results of their study. This may include writing a research paper or presenting their findings in a poster or oral presentation.

45+ Experimental Research Topics And Examples For School & College Students

unique experimental research topics

Sourav Mahahjan

unique experimental research topics

Whether it is school or college, identifying a good and quality research topic can take time for students. Experimental research, also known as methodological or analytical research, uses two or more variables and arguments for a particular scenario. In this type of argument, the influence of the independent variable on the dependent variable is considered when conducting an experimental exploration. To make a particular decision in empirical research, it is important to provide a large number of evidence. The evidence collected in practical research helps identify the consequences and reasons related to different quantities of the variables. Experimental research design is an important part of the academic cycle of any student, and often, the student needs help in preparing experimental research designs. Different types of experimental research are available for the students, such as pre-experimental research, accurate experimental research, and quasi-experimental research.

What are the different types of experimental research?

Different subjects and topics required different types of experimental research. Some commonly used experimental research are quasi-experimental research, true experiment research, and pre-experimental research.

What are the different elements of experimental research?

Any experimental research consists of three essential elements. The first element is the independent variable, which the researcher manipulates. The second variable is the dependent variable, which changes according to the first variable's manipulation. The third element is the controlled variable, which is kept constant to prevent any kind of impact on the effects created by the independent variable after the manipulation by the researcher.

What are the advantages and disadvantages of experimental research?

The use of experimental research by the researcher helps provide strong evidence regarding the different types of cause-and-impact relationships in different scenarios. The experimental research service allows the researcher to maintain control of various elements of the experimental environment. On the other hand, one of the significant disadvantages of experimental research is that it is a very time-consuming process, and sometimes, the results obtained may be disconnected from the ordinary world. 

Examples of experimental research titles:

Creating an experimental research design is very frustrating, and selecting the appropriate title becomes essential as it forms the basis of experimental research. Before choosing a topic, it becomes necessary for the students to find out literature providing disparity and research provision. This results in investing significant time and effort to search for an appropriate experimental research title. This makes the students lose patience and select the wrong research topic, impacting the overall quality of experimental research.  Examples of experimental research design are

Establishing the appropriate research title is very helpful in completing a practical research assignment . Some of the recommendations for the students are 

  • Interest:  The research tile should be based on the student's interest. This helps in improving the quality of the research.
  • Relevance:  The selected title should be relevant to the subject of the student.  It should fulfil the objectives of the course. 
  • Feasibility:  The selected topic should be practical and have adequate resources required for the study.

Are you searching for a great topic for your psychology paper ? Sometimes it seems like coming up with topics of psychology research is more challenging than the actual research and writing. Fortunately, there are plenty of great places to find inspiration and the following list contains just a few ideas to help get you started.

Finding a solid topic is one of the most important steps when writing any type of paper. It can be particularly important when you are writing a psychology research paper or essay. Psychology is such a broad topic, so you want to find a topic that allows you to adequately cover the subject without becoming overwhelmed with information.

I can always tell when a student really cares about the topic they chose; it comes through in the writing. My advice is to choose a topic that genuinely interests you, so you’ll be more motivated to do thorough research.

In some cases, such as in a general psychology class, you might have the option to select any topic from within psychology's broad reach. Other instances, such as in an  abnormal psychology  course, might require you to write your paper on a specific subject such as a psychological disorder.

As you begin your search for a topic for your psychology paper, it is first important to consider the guidelines established by your instructor.

Research Topics Within Specific Branches of Psychology

The key to selecting a good topic for your psychology paper is to select something that is narrow enough to allow you to really focus on the subject, but not so narrow that it is difficult to find sources or information to write about.

One approach is to narrow your focus down to a subject within a specific branch of psychology. For example, you might start by deciding that you want to write a paper on some sort of social psychology topic. Next, you might narrow your focus down to how persuasion can be used to influence behavior .

Other social psychology topics you might consider include:

  • Prejudice and discrimination (i.e., homophobia, sexism, racism)
  • Social cognition
  • Person perception
  • Social control and cults
  • Persuasion, propaganda, and marketing
  • Attraction, romance, and love
  • Nonverbal communication
  • Prosocial behavior

Psychology Research Topics Involving a Disorder or Type of Therapy

Exploring a psychological disorder or a specific treatment modality can also be a good topic for a psychology paper. Some potential abnormal psychology topics include specific psychological disorders or particular treatment modalities, including:

  • Eating disorders
  • Borderline personality disorder
  • Seasonal affective disorder
  • Schizophrenia
  • Antisocial personality disorder
  • Profile a  type of therapy  (i.e., cognitive-behavioral therapy, group therapy, psychoanalytic therapy)

Topics of Psychology Research Related to Human Cognition

Some of the possible topics you might explore in this area include thinking, language, intelligence, and decision-making. Other ideas might include:

  • False memories
  • Speech disorders
  • Problem-solving

Topics of Psychology Research Related to Human Development

In this area, you might opt to focus on issues pertinent to  early childhood  such as language development, social learning, or childhood attachment or you might instead opt to concentrate on issues that affect older adults such as dementia or Alzheimer's disease.

Some other topics you might consider include:

  • Language acquisition
  • Media violence and children
  • Learning disabilities
  • Gender roles
  • Child abuse
  • Prenatal development
  • Parenting styles
  • Aspects of the aging process

Do a Critique of Publications Involving Psychology Research Topics

One option is to consider writing a critique paper of a published psychology book or academic journal article. For example, you might write a critical analysis of Sigmund Freud's Interpretation of Dreams or you might evaluate a more recent book such as Philip Zimbardo's  The Lucifer Effect: Understanding How Good People Turn Evil .

Professional and academic journals are also great places to find materials for a critique paper. Browse through the collection at your university library to find titles devoted to the subject that you are most interested in, then look through recent articles until you find one that grabs your attention.

Topics of Psychology Research Related to Famous Experiments

There have been many fascinating and groundbreaking experiments throughout the history of psychology, providing ample material for students looking for an interesting term paper topic. In your paper, you might choose to summarize the experiment, analyze the ethics of the research, or evaluate the implications of the study. Possible experiments that you might consider include:

  • The Milgram Obedience Experiment
  • The Stanford Prison Experiment
  • The Little Albert Experiment
  • Pavlov's Conditioning Experiments
  • The Asch Conformity Experiment
  • Harlow's Rhesus Monkey Experiments

Topics of Psychology Research About Historical Figures

One of the simplest ways to find a great topic is to choose an interesting person in the  history of psychology  and write a paper about them. Your paper might focus on many different elements of the individual's life, such as their biography, professional history, theories, or influence on psychology.

While this type of paper may be historical in nature, there is no need for this assignment to be dry or boring. Psychology is full of fascinating figures rife with intriguing stories and anecdotes. Consider such famous individuals as Sigmund Freud, B.F. Skinner, Harry Harlow, or one of the many other  eminent psychologists .

Psychology Research Topics About a Specific Career

​Another possible topic, depending on the course in which you are enrolled, is to write about specific career paths within the  field of psychology . This type of paper is especially appropriate if you are exploring different subtopics or considering which area interests you the most.

In your paper, you might opt to explore the typical duties of a psychologist, how much people working in these fields typically earn, and the different employment options that are available.

Topics of Psychology Research Involving Case Studies

One potentially interesting idea is to write a  psychology case study  of a particular individual or group of people. In this type of paper, you will provide an in-depth analysis of your subject, including a thorough biography.

Generally, you will also assess the person, often using a major psychological theory such as  Piaget's stages of cognitive development  or  Erikson's eight-stage theory of human development . It is also important to note that your paper doesn't necessarily have to be about someone you know personally.

In fact, many professors encourage students to write case studies on historical figures or fictional characters from books, television programs, or films.

Psychology Research Topics Involving Literature Reviews

Another possibility that would work well for a number of psychology courses is to do a literature review of a specific topic within psychology. A literature review involves finding a variety of sources on a particular subject, then summarizing and reporting on what these sources have to say about the topic.

Literature reviews are generally found in the  introduction  of journal articles and other  psychology papers , but this type of analysis also works well for a full-scale psychology term paper.

Topics of Psychology Research Based on Your Own Study or Experiment

Many psychology courses require students to design an actual psychological study or perform some type of experiment. In some cases, students simply devise the study and then imagine the possible results that might occur. In other situations, you may actually have the opportunity to collect data, analyze your findings, and write up your results.

Finding a topic for your study can be difficult, but there are plenty of great ways to come up with intriguing ideas. Start by considering your own interests as well as subjects you have studied in the past.

Online sources, newspaper articles, books , journal articles, and even your own class textbook are all great places to start searching for topics for your experiments and psychology term papers. Before you begin, learn more about  how to conduct a psychology experiment .

What This Means For You

After looking at this brief list of possible topics for psychology papers, it is easy to see that psychology is a very broad and diverse subject. While this variety makes it possible to find a topic that really catches your interest, it can sometimes make it very difficult for some students to select a good topic.

If you are still stumped by your assignment, ask your instructor for suggestions and consider a few from this list for inspiration.

100 Interesting Research Paper Topics for High Schoolers

What’s covered:, how to pick the right research topic, elements of a strong research paper.

  • Interesting Research Paper Topics

Composing a research paper can be a daunting task for first-time writers. In addition to making sure you’re using concise language and your thoughts are organized clearly, you need to find a topic that draws the reader in.

CollegeVine is here to help you brainstorm creative topics! Below are 100 interesting research paper topics that will help you engage with your project and keep you motivated until you’ve typed the final period. 

A research paper is similar to an academic essay but more lengthy and requires more research. This added length and depth is bittersweet: although a research paper is more work, you can create a more nuanced argument, and learn more about your topic. Research papers are a demonstration of your research ability and your ability to formulate a convincing argument. How well you’re able to engage with the sources and make original contributions will determine the strength of your paper. 

You can’t have a good research paper without a good research paper topic. “Good” is subjective, and different students will find different topics interesting. What’s important is that you find a topic that makes you want to find out more and make a convincing argument. Maybe you’ll be so interested that you’ll want to take it further and investigate some detail in even greater depth!

For example, last year over 4000 students applied for 500 spots in the Lumiere Research Scholar Program , a rigorous research program founded by Harvard researchers. The program pairs high-school students with Ph.D. mentors to work 1-on-1 on an independent research project . The program actually does not require you to have a research topic in mind when you apply, but pro tip: the more specific you can be the more likely you are to get in!

Introduction

The introduction to a research paper serves two critical functions: it conveys the topic of the paper and illustrates how you will address it. A strong introduction will also pique the interest of the reader and make them excited to read more. Selecting a research paper topic that is meaningful, interesting, and fascinates you is an excellent first step toward creating an engaging paper that people will want to read.

Thesis Statement

A thesis statement is technically part of the introduction—generally the last sentence of it—but is so important that it merits a section of its own. The thesis statement is a declarative sentence that tells the reader what the paper is about. A strong thesis statement serves three purposes: present the topic of the paper, deliver a clear opinion on the topic, and summarize the points the paper will cover.

An example of a good thesis statement of diversity in the workforce is:

Diversity in the workplace is not just a moral imperative but also a strategic advantage for businesses, as it fosters innovation, enhances creativity, improves decision-making, and enables companies to better understand and connect with a diverse customer base.

The body is the largest section of a research paper. It’s here where you support your thesis, present your facts and research, and persuade the reader.

Each paragraph in the body of a research paper should have its own idea. The idea is presented, generally in the first sentence of the paragraph, by a topic sentence. The topic sentence acts similarly to the thesis statement, only on a smaller scale, and every sentence in the paragraph with it supports the idea it conveys.

An example of a topic sentence on how diversity in the workplace fosters innovation is:

Diversity in the workplace fosters innovation by bringing together individuals with different backgrounds, perspectives, and experiences, which stimulates creativity, encourages new ideas, and leads to the development of innovative solutions to complex problems.

The body of an engaging research paper flows smoothly from one idea to the next. Create an outline before writing and order your ideas so that each idea logically leads to another.

The conclusion of a research paper should summarize your thesis and reinforce your argument. It’s common to restate the thesis in the conclusion of a research paper.

For example, a conclusion for a paper about diversity in the workforce is:

In conclusion, diversity in the workplace is vital to success in the modern business world. By embracing diversity, companies can tap into the full potential of their workforce, promote creativity and innovation, and better connect with a diverse customer base, ultimately leading to greater success and a more prosperous future for all.

Reference Page

The reference page is normally found at the end of a research paper. It provides proof that you did research using credible sources, properly credits the originators of information, and prevents plagiarism.

There are a number of different formats of reference pages, including APA, MLA, and Chicago. Make sure to format your reference page in your teacher’s preferred style.

How To : The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

What's an Investigatory Project Exactly?

An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.

What's the Scientific Method?

For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome. The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail.

What Kind of Investigatory Projects Are There?

In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.

I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea.

Project #1: Making Soap Out of Guava

Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen .

Project #2: Used Cooking Oil as a Substitute for Diesel

We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.

Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project. And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts . Being an instant billionaire doesn't sound too bad to me.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make .

Project #3: Create Another Alternative Fuel

If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas .

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Project #4: Purifying Used Cooking Oil

Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again? Not only would that save money, but it would also benefit the environment since most people do not properly dispose of used cooking oil (no, pouring it down the drain doesn't count).

Your project goal would be to research methods of filtration or purification and test it on cooking oils. To easily demonstrate which method works best, try cooking some food in the oil produced by each one. Good food can go a long way when it comes to winning people over.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Check out the abstract and description of a similar project here .

Project #5: Alternative Methods of Producing Iodized Salt

In areas isolated from the sea, IDD or Iodine Deficiency Disease, is very common. Since these areas do not have easy access to marine foods or grocery stores, the population becomes very susceptible to the disease due to a lack of iodine in the diet. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.

If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide .

But perhaps there are other more accessible ways to create an iodized salt that people could make at home. For a starting point, take a look at this previous experiment .

Project #6: Making Biodegradable Plastic

Plastic bags are actually illegal in Santa Monica , CA (and soon to be Los Angeles ) because of their threat to the environment due to insane resistance to biodegradation. I didn't think they were that bad, but one plastic bag can take up to 1,000 years to break down completely, and it can even ruin your car along the way. So, creating a better biodegradable plastic bag would be a huge achievement.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

The only question is how one would go about doing so, and what materials could be used? That's the question you can answer for your project. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.

Project #7: Solar Water Purification

One of the biggest world problems is finding clean water. While we in the states can find purified or drinkable tap water almost anywhere, millions of people around the world don't have access to clean drinking water.

A few students decided to investigate a potential purification process using the sun's energy and an aluminum sheet. Watch the video below for more information and a complete walkthrough of their scientific process.

And if you're an overachiever, you can step it up a notch and try purifying pee instead .

Project #8: Perfecting the Paper Bridge

Of course, an investigatory project doesn't always have to answer such grand questions. This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. So, the question is, "How do design changes affect a load bearing structure?"

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Check out the video below for more information on replicating the project yourself.

Project #9: Making Instant Ice

It's summer time and the degrees are already hitting triple digits in some areas. When it's this hot, there are few things better than a glass of ice chilled water or lemonade. But what happens if you don't have ice? Can you create your own ice or cool drinks quickly by another method? Check out this clip from King of Random .

Cool, huh? But how does it work? Is there any other way to replicate this? Well, let the investigation begin. Figure out what your hypotheses will be and follow along with this video for you own investigatory project.

For more information and additional photos, be sure to check out the King of Random's full tutorial .

Project #10: Increase the Shelf-Life of Fruits and Veggies

Extending the shelf-life of perishable fruits and vegetables can make a huge difference for small farmers, street-side vendors and even your average Joe—groceries aren't cheap. What is an inexpensive and easily accessible way to make produce stay fresh longer?

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

That's the question behind this great investigatory science project featured here . While these researchers focused exclusively on chitosan coating on bananas, you can branch out (no pun intended) and try an assortment of other fruits, veggies and possible coating materials.

For more information on how to keep your fruits and vegetables fresh for longer, check out my previous article , or Yumi's recent illustration for other ideas.

Project #11: Slow the Ripening of Sliced or Chopped Produce

You could also focus your project on keeping fruits and vegetables from browning after they've already been cut up. There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Watch the video below and read this tutorial for more information and ideas.

Your project could revolve around finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one.

Project #12: Improve Memory by Thinking Dirty

If my memory was any good I would be fluent in Spanish and never need to look up the Quadratic Formula again. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be. There are folks out there who do suffer from real memory problems, so figuring out how to help improve memory makes for a great investigatory project.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

There are tons of studies on memory and memory loss that you can research. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary ? These are the types of questions you may look to answer.

This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Come up with your own theory and let the brain hacking begin.

Project #13: Improving Social Anxiety by Manipulating the Body & Mind

Science experiments don't always have to include chemicals or test tubes. The science of the mind can be just as interesting. So what's the investigation consist of?

Can you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?

Check out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask.

Project #14: Kitchen DNA Extraction

You may think studying DNA is only for professionals with super expensive lab equipment, but you can actually extract DNA from any living thing with a few basic ingredients you probably have in your kitchen like dish soap and rubbing alcohol.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Decide on something to vary, like different fruits and vegetables or types of dish soap, and come up with a hypothesis regarding which will allow you to collect the most DNA material.

You can also find more information, as well as another way to perform the experiment, here .

Project #15: Make Homemade Glue from Milk

With milk, white vinegar and baking soda, you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster, or work on different materials (wood vs. plastic vs. paper).

Project #16: Make a Battery Out of Fruits and Vegetables

How can you power a small light or device without electricity? You can make a DIY battery with a few different types of fruits and vegetables. Anything from a lemon to an apple , potato , or even passion fruit will work.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Pick a few different fruits or vegetables and form a hypothesis as to which will make the battery that puts out the most energy or lasts the longest. Once you've built your batteries, hook up a volt meter to read the output and see which one is the best.
