In this article

If you’re taking a psychology class, you’re likely tasked with designing an experiment or study at some point. Choosing the right psychology experiment idea is crucial and often depends on several factors, including the number of participants you can gather, the time constraints of your project, and the materials available to you. Before you settle on an experiment, consider these aspects carefully.

In this article, we will explore a variety of psychology experiment ideas that can inspire your project and guide you through the research process.

A Quick List of Psychology 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 ?

More Experiment Topics to Explore

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.

Tips for Finding a Good Experimental Idea

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 Psychology 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.

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.

Learn about our Editorial Process

Experimental research is research that involves using a scientific approach to examine research variables.

Below are some famous experimental research examples. Some of these studies were conducted quite a long time ago. Some were so controversial that they would never be attempted today. And some were so unethical that they would never be permitted again.

A few of these studies have also had very practical implications for modern society involving criminal investigations, the impact of television and the media, and the power of authority figures.

Examples of Experimental Research

1. pavlov’s dog: classical conditioning.

Dr. Ivan Pavlov was a physiologist studying animal digestive systems in the 1890s. In one study, he presented food to a dog and then collected its salivatory juices via a tube attached to the inside of the animal’s mouth.

As he was conducting his experiments, an annoying thing kept happening; every time his assistant would enter the lab with a bowl of food for the experiment, the dog would start to salivate at the sound of the assistant’s footsteps.

Although this disrupted his experimental procedures, eventually, it dawned on Pavlov that something else was to be learned from this problem.

Pavlov learned that animals could be conditioned into responding on a physiological level to various stimuli, such as food, or even the sound of the assistant bringing the food down the hall.

Hence, the creation of the theory of classical conditioning. One of the most influential theories in psychology still to this day.

2. Bobo Doll Experiment: Observational Learning

Dr. Albert Bandura conducted one of the most influential studies in psychology in the 1960s at Stanford University.

His intention was to demonstrate that cognitive processes play a fundamental role in learning. At the time, Behaviorism was the predominant theoretical perspective, which completely rejected all inferences to constructs not directly observable .

So, Bandura made two versions of a video. In version #1, an adult behaved aggressively with a Bobo doll by throwing it around the room and striking it with a wooden mallet. In version #2, the adult played gently with the doll by carrying it around to different parts of the room and pushing it gently.

After showing children one of the two versions, they were taken individually to a room that had a Bobo doll. Their behavior was observed and the results indicated that children that watched version #1 of the video were far more aggressive than those that watched version #2.

Not only did Bandura’s Bobo doll study form the basis of his social learning theory, it also helped start the long-lasting debate about the harmful effects of television on children.

3. The Asch Study: Conformity  

Dr. Solomon Asch was interested in conformity and the power of group pressure. His study was quite simple. Different groups of students were shown lines of varying lengths and asked, “which line is longest.”

However, out of each group, only one was an actual participant. All of the others in the group were working with Asch and instructed to say that one of the shorter lines was actually the longest.

Nearly every time, the real participant gave an answer that was clearly wrong, but the same as the rest of the group.

The study is one of the most famous in psychology because it demonstrated the power of social pressure so clearly.  

4. Car Crash Experiment: Leading Questions

In 1974, Dr. Elizabeth Loftus and her undergraduate student John Palmer designed a study to examine how fallible human judgement is under certain conditions.

They showed groups of research participants videos that depicted accidents between two cars. Later, the participants were asked to estimate the rate of speed of the cars.

Here’s the interesting part. All participants were asked the same question with the exception of a single word: “How fast were the two cars going when they ______into each other?” The word in the blank varied in its implied severity.

Participants’ estimates were completely affected by the word in the blank. When the word “smashed” was used, participants estimated the cars were going much faster than when the word “contacted” was used. 

This line of research has had a huge impact on law enforcement interrogation practices, line-up procedures, and the credibility of eyewitness testimony .

5. The 6 Universal Emotions

The research by Dr. Paul Ekman has been influential in the study of emotions. His early research revealed that all human beings, regardless of culture, experience the same 6 basic emotions: happiness, sadness, disgust, fear, surprise, and anger.

In the late 1960s, Ekman traveled to Papua New Guinea. He approached a tribe of people that were extremely isolated from modern culture. With the help of a guide, he would describe different situations to individual members and take a photo of their facial expressions.

The situations included: if a good friend had come; their child had just died; they were about to get into a fight; or had just stepped on a dead pig.

The facial expressions of this highly isolated tribe were nearly identical to those displayed by people in his studies in California.

6. The Little Albert Study: Development of Phobias  

Dr. John Watson and Dr. Rosalie Rayner sought to demonstrate how irrational fears were developed.

Their study involved showing a white rat to an infant. Initially, the child had no fear of the rat. However, the researchers then began to create a loud noise each time they showed the child the rat by striking a steel bar with a hammer.

Eventually, the child started to cry and feared the white rat. The child also developed a fear of other white, furry objects such as white rabbits and a Santa’s beard.

This study is famous because it demonstrated one way in which phobias are developed in humans, and also because it is now considered highly unethical for its mistreatment of children, lack of study debriefing , and intent to instil fear.  

7. A Class Divided: Discrimination

Perhaps one of the most famous psychological experiments of all time was not conducted by a psychologist. In 1968, third grade teacher Jane Elliott conducted one of the most famous studies on discrimination in history. It took place shortly after the assassination of Dr. Martin Luther King, Jr.

She divided her class into two groups: brown-eyed and blue-eyed students. On the first day of the experiment, she announced the blue-eyed group as superior. They received extra privileges and were told not to intermingle with the brown-eyed students.

They instantly became happier, more self-confident, and started performing better academically.

The next day, the roles were reversed. The brown-eyed students were announced as superior and given extra privileges. Their behavior changed almost immediately and exhibited the same patterns as the other group had the day before.

This study was a remarkable demonstration of the harmful effects of discrimination.

8. The Milgram Study: Obedience to Authority

Dr. Stanley Milgram conducted one of the most influential experiments on authority and obedience in 1961 at Yale University.

Participants were told they were helping study the effects of punishment on learning. Their job was to administer an electric shock to another participant each time they made an error on a test. The other participant was actually an actor in another room that only pretended to be shocked.

However, each time a mistake was made, the level of shock was supposed to increase, eventually reaching quite high voltage levels. When the real participants expressed reluctance to administer the next level of shock, the experimenter, who served as the authority figure in the room, pressured the participant to deliver the next level of shock.

The results of this study were truly astounding. A surprisingly high percentage of participants continued to deliver the shocks to the highest level possible despite the very strong objections by the “other participant.”

This study demonstrated the power of authority figures.

9. The Marshmallow Test: Delay of Gratification

The Marshmallow Test was designed by Dr. Walter Mischel to examine the role of delay of gratification and academic success.

Children ages 4-6 years old were seated at a table with one marshmallow placed in front of them. The experimenter explained that if they did not eat the marshmallow, they would receive a second one. They could then eat both.

The children that were able to delay gratification the longest were rated as significantly more competent later in life and earned higher SAT scores than children that could not withstand the temptation.  

The study has since been conceptually replicated by other researchers that have revealed additional factors involved in delay of gratification and academic achievement.

10. Stanford Prison Study: Deindividuation

Dr. Philip Zimbardo conducted one of the most famous psychological studies of all time in 1971. The purpose of the study was to investigate how the power structure in some situations can lead people to behave in ways highly uncharacteristic of their usual behavior.

College students were recruited to participate in the study. Some were randomly assigned to play the role of prison guard. The others were actually “arrested” by real police officers. They were blindfolded and taken to the basement of the university’s psychology building which had been converted to look like a prison.

Although the study was supposed to last 2 weeks, it had to be halted due to the abusive actions of the guards.

The study demonstrated that people will behave in ways they never thought possible when placed in certain roles and power structures. Although the Stanford Prison Study is so well-known for what it revealed about human nature, it is also famous because of the numerous violations of ethical principles.

The studies above are varied and focused on many different aspects of human behavior . However, each example of experimental research listed above has had a lasting impact on society. Some have had tremendous sway in how very practical matters are conducted, such as criminal investigations and legal proceedings.

Psychology is a field of study that is often not fully understood by the general public. When most people hear the term “psychology,” they think of a therapist that listens carefully to the revealing statements of a patient. The therapist then tries to help their patient learn to cope with many of life’s challenges. Nothing wrong with that.

In reality however, most psychologists are researchers. They spend most of their time designing and conducting experiments to enhance our understanding of the human condition.

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

Sourav Mahahjan

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

• 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. 

Conclusion 

Experimental research is essential in conducting scientific inquiry during an academic study. Experimental research helps students use their knowledge to improve their problem-solving and critical-thinking abilities in their academic cycle.

11+ Psychology Experiment Ideas (Goals + Methods)

Have you ever wondered why some days you remember things easily, while on others you keep forgetting? Or why certain songs make you super happy and others just…meh?

Our minds are like big, mysterious puzzles, and every day we're finding new pieces to fit. One of the coolest ways to explore our brains and the way they work is through psychology experiments.

A psychology experiment is a special kind of test or activity researchers use to learn more about how our minds work and why we behave the way we do.

It's like a detective game where scientists ask questions and try out different clues to find answers about our feelings, thoughts, and actions. These experiments aren't just for scientists in white coats but can be fun activities we all try to discover more about ourselves and others.

Some of these experiments have become so famous, they’re like the celebrities of the science world! Like the Marshmallow Test, where kids had to wait to eat a yummy marshmallow, or Pavlov's Dogs, where dogs learned to drool just hearing a bell.

Let's look at a few examples of psychology experiments you can do at home.

What Are Some Classic Experiments?

Imagine a time when the mysteries of the mind were being uncovered in groundbreaking ways. During these moments, a few experiments became legendary, capturing the world's attention with their intriguing results.

The Marshmallow Test

One of the most talked-about experiments of the 20th century was the Marshmallow Test , conducted by Walter Mischel in the late 1960s at Stanford University.

The goal was simple but profound: to understand a child's ability to delay gratification and exercise self-control.

Children were placed in a room with a marshmallow and given a choice: eat the marshmallow now or wait 15 minutes and receive two as a reward. Many kids struggled with the wait, some devouring the treat immediately, while others demonstrated remarkable patience.

But the experiment didn’t end there. Years later, Mischel discovered something astonishing. The children who had waited for the second marshmallow were generally more successful in several areas of life, from school achievements to job satisfaction!

While this experiment highlighted the importance of teaching patience and self-control from a young age, it wasn't without its criticisms. Some argued that a child's background, upbringing, or immediate surroundings might play a significant role in their choices.

Moreover, there were concerns about the ethics of judging a child's potential success based on a brief interaction with a marshmallow.

Pavlov's Dogs

Traveling further back in time and over to Russia, another classic experiment took the world by storm. Ivan Pavlov , in the early 1900s, wasn't initially studying learning or behavior. He was exploring the digestive systems of dogs.

But during his research, Pavlov stumbled upon a fascinating discovery. He noticed that by ringing a bell every time he fed his dogs, they eventually began to associate the bell's sound with mealtime. So much so, that merely ringing the bell, even without presenting food, made the dogs drool in anticipation!

This reaction demonstrated the concept of "conditioning" - where behaviors can be learned by linking two unrelated stimuli. Pavlov's work revolutionized the world's understanding of learning and had ripple effects in various areas like animal training and therapy techniques.

Pavlov came up with the term classical conditioning , which is still used today. Other psychologists have developed more nuanced types of conditioning that help us understand how people learn to perform different behaviours.

Classical conditioning is the process by which a neutral stimulus becomes associated with a meaningful stimulus , leading to the same response. In Pavlov's case, the neutral stimulus (bell) became associated with the meaningful stimulus (food), leading the dogs to salivate just by hearing the bell.

Modern thinkers often critique Pavlov's methods from an ethical standpoint. The dogs, crucial to his discovery, may not have been treated with today's standards of care and respect in research.

Both these experiments, while enlightening, also underline the importance of conducting research with empathy and consideration, especially when it involves living beings.

What is Ethical Experimentation?

The tales of Pavlov's bells and Mischel's marshmallows offer us not just insights into the human mind and behavior but also raise a significant question: At what cost do these discoveries come?

Ethical experimentation isn't just a fancy term; it's the backbone of good science. When we talk about ethics, we're referring to the moral principles that guide a researcher's decisions and actions. But why does it matter so much in the realm of psychological experimentation?

An example of an experiment that had major ethical issues is an experiment called the Monster Study . This study was conducted in 1936 and was interested in why children develop a stutter.

The major issue with it is that the psychologists treated some of the children poorly over a period of five months, telling them things like “You must try to stop yourself immediately. Don’t ever speak unless you can do it right.”

You can imagine how that made the children feel!

This study helped create guidelines for ethical treatment in experiments. The guidelines include:

Respect for Individuals: Whether it's a dog in Pavlov's lab or a child in Mischel's study room, every participant—human or animal—deserves respect. They should never be subjected to harm or undue stress. For humans, informed consent (knowing what they're signing up for) is a must. This means that if a child is participating, they, along with their guardians, should understand what the experiment entails and agree to it without being pressured.

Honesty is the Best Policy: Researchers have a responsibility to be truthful. This means not only being honest with participants about the study but also reporting findings truthfully, even if the results aren't what they hoped for. There can be exceptions if an experiment will only succeed if the participants aren't fully aware, but it has to be approved by an ethics committee .

Safety First: No discovery, no matter how groundbreaking, is worth harming a participant. The well-being and mental, emotional, and physical safety of participants is paramount. Experiments should be designed to minimize risks and discomfort.

Considering the Long-Term: Some experiments might have effects that aren't immediately obvious. For example, while a child might seem fine after participating in an experiment, they could feel stressed or anxious later on. Ethical researchers consider and plan for these possibilities, offering support and follow-up if needed.

The Rights of Animals: Just because animals can't voice their rights doesn't mean they don't have any. They should be treated with care, dignity, and respect. This means providing them with appropriate living conditions, not subjecting them to undue harm, and considering alternatives to animal testing when possible.

While the world of psychological experiments offers fascinating insights into behavior and the mind, it's essential to tread with care and compassion. The golden rule? Treat every participant, human or animal, as you'd wish to be treated. After all, the true mark of a groundbreaking experiment isn't just its findings but the ethical integrity with which it's conducted.

So, even if you're experimenting at home, please keep in mind the impact your experiments could have on the people and beings around you!

Let's get into some ideas for experiments.

1) Testing Conformity

Our primary aim with this experiment is to explore the intriguing world of social influences, specifically focusing on how much sway a group has over an individual's decisions. This social influence is called groupthink .

Humans, as social creatures, often find solace in numbers, seeking the approval and acceptance of those around them. But how deep does this need run? Does the desire to "fit in" overpower our trust in our own judgments?

This experiment not only provides insights into these questions but also touches upon the broader themes of peer pressure, societal norms, and individuality. Understanding this could shed light on various real-world situations, from why fashion trends catch on to more critical scenarios like how misinformation can spread.

Method: This idea is inspired by the classic Asch Conformity Experiments . Here's a simple way to try it:

• Assemble a group of people (about 7-8). Only one person will be the real participant; the others will be in on the experiment.
• Show the group a picture of three lines of different lengths and another line labeled "Test Line."
• Ask each person to say out loud which of the three lines matches the length of the "Test Line."
• Unknown to the real participant, the other members will intentionally choose the wrong line. This is to see if the participant goes along with the group's incorrect choice, even if they can see it's wrong.

Real-World Impacts of Groupthink

Groupthink is more than just a science term; we see it in our daily lives:

Decisions at Work or School: Imagine being in a group where everyone wants to do one thing, even if it's not the best idea. People might not speak up because they're worried about standing out or being the only one with a different opinion.

Wrong Information: Ever heard a rumor that turned out to be untrue? Sometimes, if many people believe and share something, others might believe it too, even if it's not correct. This happens a lot on the internet.

Peer Pressure: Sometimes, friends might all want to do something that's not safe or right. People might join in just because they don't want to feel left out.

Missing Out on New Ideas: When everyone thinks the same way and agrees all the time, cool new ideas might never get heard. It's like always coloring with the same crayon and missing out on all the other bright colors!

2) Testing Color and Mood

We all have favorite colors, right? But did you ever wonder if colors can make you feel a certain way? Color psychology is the study of how colors can influence our feelings and actions.

For instance, does blue always calm us down? Does red make us feel excited or even a bit angry? By exploring this, we can learn how colors play a role in our daily lives, from the clothes we wear to the color of our bedroom walls.

• Find a quiet room and set up different colored lights or large sheets of colored paper: blue, red, yellow, and green.
• Invite some friends over and let each person spend a few minutes under each colored light or in front of each colored paper.
• After each color, ask your friends to write down or talk about how they feel. Are they relaxed? Energized? Happy? Sad?

Researchers have always been curious about this. Some studies have shown that colors like blue and green can make people feel calm, while colors like red might make them feel more alert or even hungry!

Real-World Impacts of Color Psychology

Ever noticed how different places use colors?

Hospitals and doctors' clinics often use soft blues and greens. This might be to help patients feel more relaxed and calm.

Many fast food restaurants use bright reds and yellows. These colors might make us feel hungry or want to eat quickly and leave.

Classrooms might use a mix of colors to help students feel both calm and energized.

3) Testing Music and Brainpower

Think about your favorite song. Do you feel smarter or more focused when you listen to it? This experiment seeks to understand the relationship between music and our brain's ability to remember things. Some people believe that certain types of music, like classical tunes, can help us study or work better. Let's find out if it's true!

• Prepare a list of 10-15 things to remember, like a grocery list or names of places.
• Invite some friends over. First, let them try to memorize the list in a quiet room.
• After a short break, play some music (try different types like pop, classical, or even nature sounds) and ask them to memorize the list again.
• Compare the results. Was there a difference in how much they remembered with and without music?

The " Mozart Effect " is a popular idea. Some studies in the past suggested that listening to Mozart's music might make people smarter, at least for a little while. But other researchers think the effect might not be specific to Mozart; it could be that any music we enjoy boosts our mood and helps our brain work better.

Real-World Impacts of Music and Memory

Think about how we use music:

• Study Sessions: Many students listen to music while studying, believing it helps them concentrate better.
• Workout Playlists: Gyms play energetic music to keep people motivated and help them push through tough workouts.
• Meditation and Relaxation: Calm, soothing sounds are often used to help people relax or meditate.

4) Testing Dreams and Food

Ever had a really wild dream and wondered where it came from? Some say that eating certain foods before bedtime can make our dreams more vivid or even a bit strange.

This experiment is all about diving into the dreamy world of sleep to see if what we eat can really change our nighttime adventures. Can a piece of chocolate or a slice of cheese transport us to a land of wacky dreams? Let's find out!

• Ask a group of friends to keep a "dream diary" for a week. Every morning, they should write down what they remember about their dreams.
• For the next week, ask them to eat a small snack before bed, like cheese, chocolate, or even spicy foods.
• They should continue writing in their "dream diary" every morning.
• At the end of the two weeks, compare the dream notes. Do the dreams seem different during the snack week?

The link between food and dreams isn't super clear, but some people have shared personal stories. For example, some say that spicy food can lead to bizarre dreams. Scientists aren't completely sure why, but it could be related to how food affects our body temperature or brain activity during sleep.

A cool idea related to this experiment is that of vivid dreams , which are very clear, detailed, and easy to remember dreams. Some people are even able to control their vivid dreams, or say that they feel as real as daily, waking life !

Real-World Impacts of Food and Dreams

Our discoveries might shed light on:

• Bedtime Routines: Knowing which foods might affect our dreams can help us choose better snacks before bedtime, especially if we want calmer sleep.
• Understanding Our Brain: Dreams can be mysterious, but studying them can give us clues about how our brains work at night.
• Cultural Beliefs: Many cultures have myths or stories about foods and dreams. Our findings might add a fun twist to these age-old tales!

5) Testing Mirrors and Self-image

Stand in front of a mirror. How do you feel? Proud? Shy? Curious? Mirrors reflect more than just our appearance; they might influence how we think about ourselves.

This experiment delves into the mystery of self-perception. Do we feel more confident when we see our reflection? Or do we become more self-conscious? Let's take a closer look.

• Set up two rooms: one with mirrors on all walls and another with no mirrors at all.
• Invite friends over and ask them to spend some time in each room doing normal activities, like reading or talking.
• After their time in both rooms, ask them questions like: "Did you think about how you looked more in one room? Did you feel more confident or shy?"
• Compare the responses to see if the presence of mirrors changes how they feel about themselves.

Studies have shown that when people are in rooms with mirrors, they can become more aware of themselves. Some might stand straighter, fix their hair, or even change how they behave. The mirror acts like an audience, making us more conscious of our actions.

Real-World Impacts of Mirrors and Self-perception

Mirrors aren't just for checking our hair. Ever wonder why clothing stores have so many mirrors? They might help shoppers visualize themselves in new outfits, encouraging them to buy.

Mirrors in gyms can motivate people to work out with correct form and posture. They also help us see progress in real-time!

And sometimes, looking in a mirror can be a reminder to take care of ourselves, both inside and out.

But remember, what we look like isn't as important as how we act in the world or how healthy we are. Some people claim that having too many mirrors around can actually make us more self conscious and distract us from the good parts of ourselves.

Some studies are showing that mirrors can actually increase self-compassion , amongst other things. As any tool, it seems like mirrors can be both good and bad, depending on how we use them!

6) Testing Plants and Talking

Have you ever seen someone talking to their plants? It might sound silly, but some people believe that plants can "feel" our vibes and that talking to them might even help them grow better.

In this experiment, we'll explore whether plants can indeed react to our voices and if they might grow taller, faster, or healthier when we chat with them.

• Get three similar plants, placing each one in a separate room.
• Talk to the first plant, saying positive things like "You're doing great!" or singing to it.
• Say negative things to the second plant, like "You're not growing fast enough!"
• Don't talk to the third plant at all; let it be your "silent" control group .
• Water all plants equally and make sure they all get the same amount of light.
• At the end of the month, measure the growth of each plant and note any differences in their health or size.

The idea isn't brand new. Some experiments from the past suggest plants might respond to sounds or vibrations. Some growers play music for their crops, thinking it helps them flourish.

Even if talking to our plants doesn't have an impact on their growth, it can make us feel better! Sometimes, if we are lonely, talking to our plants can help us feel less alone. Remember, they are living too!

Real-World Impacts of Talking to Plants

If plants do react to our voices, gardeners and farmers might adopt new techniques, like playing music in greenhouses or regularly talking to plants.

Taking care of plants and talking to them could become a recommended activity for reducing stress and boosting mood.

And if plants react to sound, it gives us a whole new perspective on how connected all living things might be .

7) Testing Virtual Reality and Senses

Virtual reality (VR) seems like magic, doesn't it? You put on a headset and suddenly, you're in a different world! But how does this "new world" affect our senses? This experiment wants to find out how our brains react to VR compared to the real world. Do we feel, see, or hear things differently? Let's get to the bottom of this digital mystery!

• You'll need a VR headset and a game or experience that can be replicated in real life (like walking through a forest). If you don't have a headset yourself, there are virtual reality arcades now!
• Invite friends to first experience the scenario in VR.
• Afterwards, replicate the experience in the real world, like taking a walk in an actual forest.
• Ask them questions about both experiences: Did one seem more real than the other? Which sounds were more clear? Which colors were brighter? Did they feel different emotions?

As VR becomes more popular, scientists have been curious about its effects. Some studies show that our brains can sometimes struggle to tell the difference between VR and reality. That's why some people might feel like they're really "falling" in a VR game even though they're standing still.

Real-World Impacts of VR on Our Senses

Schools might use VR to teach lessons, like taking students on a virtual trip to ancient Egypt. Understanding how our senses react in VR can also help game designers create even more exciting and realistic games.

Doctors could use VR to help patients overcome fears or to provide relaxation exercises. This is actually already a method therapists can use for helping patients who have serious phobias. This is called exposure therapy , which basically means slowly exposing someone (or yourself) to the thing you fear, starting from very far away to becoming closer.

For instance, if someone is afraid of snakes. You might show them images of snakes first. Once they are comfortable with the picture, they can know there is one in the next room. Once they are okay with that, they might use a VR headset to see the snake in the same room with them, though of course there is not an actual snake there.

8) Testing Sleep and Learning

We all know that feeling of trying to study or work when we're super tired. Our brains feel foggy, and it's hard to remember stuff. But how exactly does sleep (or lack of it) influence our ability to learn and remember things?

With this experiment, we'll uncover the mysteries of sleep and see how it can be our secret weapon for better learning.

• Split participants into two groups.
• Ask both groups to study the same material in the evening.
• One group goes to bed early, while the other stays up late.
• The next morning, give both groups a quiz on what they studied.
• Compare the results to see which group remembered more.

Sleep and its relation to learning have been explored a lot. Scientists believe that during sleep, especially deep sleep, our brains sort and store new information. This is why sometimes, after a good night's rest, we might understand something better or remember more.

Real-World Impacts of Sleep and Learning

Understanding the power of sleep can help:

• Students: If they know the importance of sleep, students might plan better, mixing study sessions with rest, especially before big exams.
• Workplaces: Employers might consider more flexible hours, understanding that well-rested employees learn faster and make fewer mistakes.
• Health: Regularly missing out on sleep can have other bad effects on our health. So, promoting good sleep is about more than just better learning.

9) Testing Social Media and Mood

Have you ever felt different after spending time on social media? Maybe happy after seeing a friend's fun photos, or a bit sad after reading someone's tough news.

Social media is a big part of our lives, but how does it really affect our mood? This experiment aims to shine a light on the emotional roller-coaster of likes, shares, and comments.

• Ask participants to note down how they're feeling - are they happy, sad, excited, or bored?
• Have them spend a set amount of time (like 30 minutes) on their favorite social media platforms.
• After the session, ask them again about their mood. Did it change? Why?
• Discuss what they saw or read that made them feel that way.

Previous research has shown mixed results. Some studies suggest that seeing positive posts can make us feel good, while others say that too much time on social media can make us feel lonely or left out.

Real-World Impacts of Social Media on Mood

Understanding the emotional impact of social media can help users understand their feelings and take breaks if needed. Knowing is half the battle! Additionally, teachers and parents can guide young users on healthy social media habits, like limiting time or following positive accounts.

And if it's shown that social media does impact mood, social media companies can design friendlier, less stressful user experiences.

But even if the social media companies don't change things, we can still change our social media habits to make ourselves feel better.

10) Testing Handwriting or Typing

Think about the last time you took notes. Did you grab a pen and paper or did you type them out on a computer or tablet?

Both ways are popular, but there's a big question: which method helps us remember and understand better? In this experiment, we'll find out if the classic art of handwriting has an edge over speedy typing.

• Divide participants into two groups.
• Present a short lesson or story to both groups.
• One group will take notes by hand, while the other will type them out.
• After some time, quiz both groups on the content of the lesson or story.
• Compare the results to see which note-taking method led to better recall and understanding.

Studies have shown some interesting results. While typing can be faster and allows for more notes, handwriting might boost memory and comprehension because it engages the brain differently, making us process the information as we write.

Importantly, each person might find one or the other works better for them. This could be useful in understanding our learning habits and what instructional style would be best for us.

Real-World Impacts of Handwriting vs. Typing

Knowing the pros and cons of each method can:

• Boost Study Habits: Students can pick the method that helps them learn best, especially during important study sessions or lectures.
• Work Efficiency: In jobs where information retention is crucial, understanding the best method can increase efficiency and accuracy.
• Tech Design: If we find out more about how handwriting benefits us, tech companies might design gadgets that mimic the feel of writing while combining the advantages of digital tools.

11) Testing Money and Happiness

We often hear the saying, "Money can't buy happiness," but is that really true? Many dream of winning the lottery or getting a big raise, believing it would solve all problems.

In this experiment, we dig deep to see if there's a real connection between wealth and well-being.

• Survey a range of participants, from those who earn a little to those who earn a lot, about their overall happiness. You can keep it to your friends and family, but that might not be as accurate as surveying a wider group of people.
• Ask them to rank things that bring them joy and note if they believe more money would boost their happiness. You could try different methods, one where you include some things that they have to rank, such as gardening, spending time with friends, reading books, learning, etc. Or you could just leave a blank list that they can fill in with their own ideas.
• Study the data to find patterns or trends about income and happiness.

Some studies have found money can boost happiness, especially when it helps people out of tough financial spots. But after reaching a certain income, extra dollars usually do not add much extra joy.

In fact, psychologists just realized that once people have an income that can comfortably support their needs (and some of their wants), they stop getting happier with more . That number is roughly $75,000, but of course that depends on the cost of living and how many members are in the family.

Real-World Impacts of Money and Happiness

If we can understand the link between money and joy, it might help folks choose jobs they love over jobs that just pay well. And instead of buying things, people might spend on experiences, like trips or classes, that make lasting memories.

Most importantly, we all might spend more time on hobbies, friends, and family, knowing they're big parts of what makes life great.

Some people are hoping that with Artificial Intelligence being able to do a lot of the less well-paying jobs, people might be able to do work they enjoy more, all while making more money and having more time to do the things that make them happy.

12) Testing Temperature and Productivity

Have you ever noticed how a cold classroom or office makes it harder to focus? Or how on hot days, all you want to do is relax? In this experiment, we're going to find out if the temperature around us really does change how well we work.

• Find a group of participants and a room where you can change the temperature.
• Set the room to a chilly temperature and give the participants a set of tasks to do.
• Measure how well and quickly they do these tasks.
• The next day, make the room comfortably warm and have them do similar tasks.
• Compare the results to see if the warmer or cooler temperature made them work better.

Some studies have shown that people can work better when they're in a room that feels just right, not too cold or hot. Being too chilly can make fingers slow, and being too warm can make minds wander.

What temperature is "just right"? It won't be the same for everyone, but most people find it's between 70-73 degrees Fahrenheit (21-23 Celsius).

Real-World Implications of Temperature and Productivity

If we can learn more about how temperature affects our work, teachers might set classroom temperatures to help students focus and learn better, offices might adjust temperatures to get the best work out of their teams, and at home, we might find the best temperature for doing homework or chores quickly and well.

Interestingly, temperature also has an impact on our sleep quality. Most people find slightly cooler rooms to be better for good sleep. While the daytime temperature between 70-73F is good for productivity, a nighttime temperature around 65F (18C) is ideal for most people's sleep.

Psychology is like a treasure hunt, where the prize is understanding ourselves better. With every experiment, we learn a little more about why we think, feel, and act the way we do. Some of these experiments might seem simple, like seeing if colors change our mood or if being warm helps us work better. But even the simple questions can have big answers that help us in everyday life.

Remember, while doing experiments is fun, it's also important to always be kind and think about how others feel. We should never make someone uncomfortable just for a test. Instead, let's use these experiments to learn and grow, helping to make the world a brighter, more understanding place for everyone.

Ideas for Psychology Experiments

Inspiration for psychology experiments is all around if you know where to look

Kendra Cherry, MS, is a psychosocial rehabilitation specialist, psychology educator, and author of the "Everything Psychology Book."

Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital.

Psychology experiments can run the gamut from simple to complex. Students are often expected to design—and sometimes perform—their own experiments, but finding great experiment ideas can be a little challenging. Fortunately, inspiration is all around if you know where to look—from your textbooks to the questions that you have about your own life.

Always discuss your idea with your instructor before beginning your experiment—particularly if your research involves human participants. (Note: You'll probably need to submit a proposal and get approval from your school's institutional review board.)

At a Glance

If you are looking for an idea for psychology experiments, start your search early and make sure you have the time you need. Doing background research, choosing an experimental design, and actually performing your experiment can be quite the process. Keep reading to find some great psychology experiment ideas that can serve as inspiration. You can then find ways to adapt these ideas for your own assignments.

15 Ideas for Psychology Experiments

Most of these experiments can be performed easily at home or at school. That said, you will need to find out if you have to get approval from your teacher or from an institutional review board before getting started.

The following are some questions you could attempt to answer as part of a psychological experiment:

• Are people really able to "feel like someone is watching" them ? Have some participants sit alone in a room and have them note when they feel as if they are being watched. Then, see how those results line up to your own record of when participants were actually being observed.
• Can certain colors improve learning ? You may have heard teachers or students claim that printing text on green paper helps students read better, or that yellow paper helps students perform better on math exams. Design an experiment to see whether using a specific color of paper helps improve students' scores on math exams.
• Can color cause physiological reactions ? Perform an experiment to determine whether certain colors cause a participant's blood pressure to rise or fall.
• Can different types of music lead to different physiological responses ? Measure the heart rates of participants in response to various types of music to see if there is a difference.
• Can smelling one thing while tasting another impact a person's ability to detect what the food really is ? Have participants engage in a blind taste test where the smell and the food they eat are mismatched. Ask the participants to identify the food they are trying and note how accurate their guesses are.
• Could a person's taste in music offer hints about their personality ? Previous research has suggested that people who prefer certain styles of music tend to exhibit similar  personality traits. Administer a personality assessment and survey participants about their musical preferences and examine your results.
• Do action films cause people to eat more popcorn and candy during a movie ? Have one group of participants watch an action movie, and another group watch a slow-paced drama. Compare how much popcorn is consumed by each group.
• Do colors really impact moods ? Investigate to see if the  color blue makes people feel calm, or if the color red leaves them feeling agitated.
• Do creative people see  optical illusions  differently than more analytical people ? Have participants complete an assessment to measure their level of creative thinking. Then ask participants to look at optical illusions and note what they perceive.
• Do people rate individuals with perfectly symmetrical faces as more beautiful than those with asymmetrical faces ? Create sample cards with both symmetrical and asymmetrical faces and ask participants to rate the attractiveness of each picture.
• Do people who use social media exhibit signs of addiction ? Have participants complete an assessment of their social media habits, then have them complete an addiction questionnaire.
• Does eating breakfast help students do better in school ? According to some, eating breakfast can have a beneficial influence on school performance. For your experiment, you could compare the test scores of students who ate breakfast to those who did not.
• Does sex influence short-term memory ? You could arrange an experiment that tests whether men or women are better at remembering specific types of information.
• How likely are people to conform in groups ? Try this experiment to see what percentage of people are likely to conform . Enlist confederates to give the wrong response to a math problem and then see if the participants defy or conform to the rest of the group.
• How much information can people store in short-term memory ? Have participants study a word list and then test their memory. Try different versions of the experiment to see which memorization strategies, like chunking or mnemonics, are most effective.

Once you have an idea, the next step is to learn more about  how to conduct a psychology experiment .

Psychology Experiments on Your Interests

If none of the ideas in the list above grabbed your attention, there are other ways to find inspiration for your psychology experiments.

How do you come up with good psychology experiments? One of the most effective approaches is to look at the various problems, situations, and questions that you are facing in your own life.

You can also think about the things that interest you. Start by considering the topics you've studied in class thus far that have really piqued your interest. Then, whittle the list down to two or three major areas within psychology that seem to interest you the most.

From there, make a list of questions you have related to the topic. Any of these questions could potentially serve as an experiment idea.

Use Textbooks for Inspiration for Psychology Experiments

Your psychology textbooks are another excellent source you can turn to for experiment ideas. Choose the chapters or sections that you find particularly interesting—perhaps it's a chapter on  social psychology  or a section on child development.

Start by browsing the experiments discussed in your book. Then think of how you could devise an experiment related to some of the questions your text asks. The reference section at the back of your textbook can also serve as a great source for additional reference material.

Discuss Psychology Experiments with Other Students

It can be helpful to brainstorm with your classmates to gather outside ideas and perspectives. Get together with a group of students and make a list of interesting ideas, subjects, or questions you have.

The information from your brainstorming session can serve as a basis for your experiment topic. It's also a great way to get feedback on your own ideas and to determine if they are worth exploring in greater depth.

Study Classic Psychology Experiments

Taking a closer look at a classic psychology experiment can be an excellent way to trigger some unique and thoughtful ideas of your own. To start, you could try conducting your own version of a famous experiment or even updating a classic experiment to assess a slightly different question.

Famous Psychology Experiments

Examples of famous psychology experiments that might be a source of further questions you'd like to explore include:

• Marshmallow test experiments
• Little Albert experiment
• Hawthorne effect experiments
• Bystander effect experiments
• Robbers Cave experiments
• Halo effect experiments
• Piano stairs experiment
• Cognitive dissonance experiments
• False memory experiments

You might not be able to replicate an experiment exactly (lots of classic psychology experiments have ethical issues that would preclude conducting them today), but you can use well-known studies as a basis for inspiration.

Review the Literature on Psychology Experiments

If you have a general idea about what topic you'd like to experiment, you might want to spend a little time doing a brief literature review before you start designing. In other words, do your homework before you invest too much time on an idea.

Visit your university library and find some of the best books and articles that cover the particular topic you are interested in. What research has already been done in this area? Are there any major questions that still need to be answered? What were the findings of previous psychology experiments?

Tackling this step early will make the later process of writing the introduction  to your  lab report  or research paper much easier.

Ask Your Instructor About Ideas for Psychology Experiments

If you have made a good effort to come up with an idea on your own but you're still feeling stumped, it might help to talk to your instructor. Ask for pointers on finding a good experiment topic for the specific assignment. You can also ask them to suggest some other ways you could generate ideas or inspiration.

While it can feel intimidating to ask for help, your instructor should be more than happy to provide some guidance. Plus, they might offer insights that you wouldn't have gathered on your own. Your instructor probably has lots of ideas for psychology experiments that would be worth exploring.

If you need to design or conduct psychology experiments, there are plenty of great ideas (both old and new) for you to explore. Consider an idea from the list above or turn some of your own questions about the human mind and behavior into an experiment.

Before you dive in, make sure that you are observing the guidelines provided by your instructor and always obtain the appropriate permission before conducting any research with human or animal subjects.

Frequently Asked Questions

Finding a topic for a research paper is much like finding an idea for an experiment. Start by considering your own interests, or browse though your textbooks for inspiration. You might also consider looking at online news stories or journal articles as a source of inspiration.

Three of the most classic social psychology experiments are:

• The Asch Conformity Experiment : This experiment involved seeing if people would conform to group pressure when rating the length of a line.
• The Milgram Obedience Experiment : This experiment involved ordering participants to deliver what they thought was a painful shock to another person.
• The Stanford Prison Experiment : This experiment involved students replicating a prison environment to see how it would affect participant behavior.
