1. Define key variables.
<ol>
	<li>Create an operational definition (i.e., a clear description of exactly what a researcher means by a concept) of power.
	<ol>
		<li>For the purposes of this experiment, power is measured by relative authority on the college campus, e.g., a residence hall assistant has more power than a student that does not hold this position.  </li>
	</ol>
	</li>
	<li>Create an operational definition (i.e., a clear description of exactly what a researcher means by a concept) of imitation.
	<ol>
		<li>For purposes of this experiment, imitation is defined as the participant’s non-conscious mimicking of the confederate by making similar movements with their feet and hands. </li>
	</ol>
	</li>
</ol>
2. Conduct the study.
<ol>
	<li>Meet the student/participant at the lab.</li>
	<li>Provide participant with informed consent, a brief description of the research, a sense of the procedure, an indication of potential risks/benefits, the right of withdrawal at any time, and a manner to get help if they experience discomfort.</li>
	<li>Have the participant sit at a desk on the window side of a one-way mirror. </li>
	<li> Tell the participant that you would like them to remember the behaviors of another participant (a confederate in actuality) who will sit on the mirror side of the one-way mirror while they work on GRE Math problems (Figure 1).1 
	<img alt="GRE math problems with multiple-choice answers; includes speed, algebra, probability, and logic concepts." src="/files/ftp_upload/10051/10051fig1.jpg" data-altupdatedat="1761830439000" data-alt="Figure 1"> 
	Figure 1: An example of the GRE math problems given to the confederate.</li>
	<li>Train the confederate.
	<ol>
		<li>Confederates, also known as stooges, are part of the experiment and act exactly as the researcher instructs. Participants are led to believe that a confederate is a participant.</li>
		<li> Train the confederate to engage in 7 key behaviors: playing with their hair, putting a pen in their mouth, tapping their fingers, touching their face, wrinkling their nose, making whistling sounds, and leaning back in their chair.</li>
		<li>For consistency, the confederate should match each behavior to a specific question on the GRE math problems. For example, when the confederate works on problem 1, they should play with hair, when they work on question 2, they should put a pen in their mouth, for question 3, they should tap their fingers, etc. This will ensure that all behaviors occur at the same relative time for all participants.</li>
	</ol>
	</li>
	<li> Lead the confederate to their chair in front of the mirror-side of the one-way mirror.</li>
	<li>Treat the confederate like a participant, giving them informed consent (as described in 2.2 above), and then explain that the participant will complete the sheet of GRE math problems.
	<ol>
		<li>On the window side of the one-way mirror, the participant has clear sight and sound of this interaction between the researcher and the confederate.</li>
	</ol>
	</li>
	<li> Return to the participant with a pen and a copy of the GRE problems. Instruct the participant to mark ones they think the confederate got correct with a star, and those they think the confederate got incorrect with an X.
	<ol>
		<li>In one condition, tell the participant that the confederate is a head residence hall assistant on campus.</li>
		<li>In the other condition tell the participant that the confederate is another participant “just like you.”</li>
	</ol>
	</li>
	<li>Sit off to the side of the participant and record the participant’s behaviors on a chart (Figure 2). 
	<img alt="Participant behavior chart; power dynamics study; compares gestures like playing with hair, pen use." src="/files/ftp_upload/10051/10051fig2.jpg" data-altupdatedat="1761830439000" data-alt="Figure 2"> 
	Figure 2: Chart used by experimenter to record participant’s behavior.</li>
</ol>
3. Debrief the participant.
<ol>
	<li> Tell the participant the nature of the study.
	<ol>
		<li>“Thank you for participating. In this study I was trying to determine if a fellow participant’s perceived power or authority would increase the chances that a participant like you would mimic their behavior. There were two groups in the study, one group was told the person they were observing is a residence hall assistant, while the other group was told they were just another participant. We hypothesized that those who observed the resident hall assistant would be more likely to mimic their behavior because they are an authority figure.”</li>
	</ol>
	</li>
	<li>Explain explicitly why deception was necessary for the experiment.
	<ol>
		<li>“We want to tell you about the deception we used in this study. We used deception by telling you the person you observed was another participant, but in reality they were a part of the study and served as a confederate. We did this to make the experiment feel real and to ensure that person being observed acting similarly for each participant in the study. If participants were to know the true reasoning and hypothesis behind the study, they may perform in an unnatural way by trying to live up to the experimenter’s perceived expectations. To eliminate this problem, it was necessary for us to use the confederate. Because of the nature of the deception, it is quite natural for participants to not realize that they were being deceived.”</li>
	</ol>
	</li>
</ol>

Confederates are common in psychology research. For example, a confederate can give participants specific suggestions or information that can later influence memory.2 Researchers also use confederates in field studies to recreate everyday interactions. For example, when a male confederate interacted with a baby, women liked him better than when he ignored the baby.3 This study replicates and extends previous research on embodiment, which showed that those who want to feel affiliated to another perso...

experimentation using a confederate

When orchestrating an experiment, it is important that the experience elicits the most natural reactions from the participants as possible. Researchers accomplish much of this through their creation of the experimental settings.
Many research projects focus on interactions between two or more people.&#160; In these situations the environment or setting must often be less natural; often only one person can be a true participant and others in the study need to be &#8220;confederates,&#8221; that is, allegedly unbiased participants whom, in actuality, act according to the researcher&#8217;s directions.
This video uses a two-group experiment to see if participants are more likely to imitate a person with more power versus similar power compared to the participant.&#160; The video also highlights the use of research confederates.
Psychological studies often use higher sample sizes than studies in other sciences.&#160; A large number of participants helps to better ensure that the population under study is better represented, i.e. the margin of error accompanied by studying human behavior is sufficiently accounted for.&#160; Further, human participants for research like this are often readily available and the experiment is quick and inexpensive to replicate so we want to use as many participants as possible.&#160; In this video we demonstrate this experiment using just one participant.&#160; However, as represented in the results, we used a total of 156 participants to reach the experiment&#8217;s conclusions.

The procedure demonstrated in this research was repeated 155 times so that the results reflect data from 156 total participants. 78 of the participants were told that the confederate was a head residence hall assistant (first condition) while the other 78 participants were told that the confederate has no such position of power, i.e., was just a regular student like the participant (second condition).
The data graphed reflect the average number of behaviors the participant mimicked wh...

Confederates, or research actors, are commonly employed in psychology experiments to secretly participate along with actual subjects.By using confederates, researchers study participants in complex social settings and reliably capture na?ve reactions.Through the incorporation of confederates, this video demonstrates how to design, perform, analyze, and interpret an experiment where non-conscious mimicry is reliably measured.In this case, researchers manipulate the experimental setting to test whether a participant is more likely to mimic a person with greater social power versus a person with similar power.This experiment uses a two-group design with a critical element: a hired actor or confederate. The confederate acts according to the researcher?s directions, which allows for secret observations.Subjects think that they are observing other participants? behaviors as they work on math problems through a one-way mirror. In actuality, the researcher is interested in whether or not the subjects subsequently mimic behaviors acted out by the confederate as he works on each math problem.Half of the student participants are told that the confederate is in a more powerful position as a head residence hall assistant, whereas the other half are told that the confederate is equal in power as a regular student.The participants are then asked to score the questions that they think the confederate got right or wrong. At the same time participants are scoring each problem, the researcher observes them and tallies the dependent variable?the number of behaviors mimicked.If the perceived status of the confederate influences the participants? responses, those who believe the confederate had higher power will mimic a greater number of behaviors than those who believe the confederate has equal power.To conduct the experiment, you will need: informed consent and final debriefing papers, pens, a sheet of GRE-level math problems, a one-way mirror for observation, and a chart of behaviors to tally.To begin the experiment, meet the participant in the lab. Guide all participants through the consent process and discuss the overall plan for the session.Lead the participant into the window side of the room with a one-way mirror. State that they will be viewing another participant on the mirrored side as they complete GRE-level math problems. Convey to the participant that they need to carefully remember behaviors performed by the other participant.While the participant is waiting in the room for someone to appear on the other side, meet the confederate actor. Instruct them to respectively engage in the following seven key behaviors in order with seven math problems: playing with their hair, putting a pen in their mouth, tapping their fingers on the desk, touching their face, wrinkling their nose, whistling, and leaning back in the chair.Now lead the confederate to the chair in front of the mirror-side of the one-way mirror. Provide them with the same informed consent papers and research guidelines so that the participant believes the confederate is indeed another normal participant. Before leaving the room, hand a sheet of math problems to the confederate to complete.After handing the confederate the sheet of GRE math problems, return to the original participant with a pen and a copy of the math problems. Tell them that the other observed participant is either: (1) a head residence hall assistant on campus, or (2) another normal student participant.After the confederate leaves the room, instruct the participant to mark questions they think the confederate got correct with a star or incorrect with an X. Simultaneously check whether or not the participant imitates the confederate?s behavior when scoring each question.At the conclusion of the experiment, debrief participants and explain why deception was necessary for the experiment.To analyze how confederates influence the outcome, tally the number of behaviors mimicked for each condition.The data are then graphed by plotting the mean number of behaviors mimicked in each condition. In this experiment, participants who believed the confederate was a Resident Hall Assistant imitated a greater number of behaviors than those who believed the confederate was a student.Now that you are familiar with how psychology experiments are cleverly implemented with confederates, let?s take a look at how various researchers employ confederates to affect social behaviors.In a recent study, confederates were used to examine social influences on remembering. A confederate gave participants misinformation that led to incorrect memories being recalled. Thus, the use of confederates shows that memory recall is socially contagious.In another experiment, confederates were used to examine social cues of attraction. When a male confederate interacted with a female confederate?s baby, women who witnessed the interaction liked him better than when he ignored the baby.Neuroscientists are interested in how our brains process mimicking the actions of others. Discovering the neurophysiological correlates is critical for understanding perception and mechanisms underlying social cognitive disorders.You?ve just watched JoVE?s introduction to using confederates in experimental studies. Now you should have a good understanding of how to design and perform the experiment, as well as analyze results and apply the phenomenon.Thanks for watching!?

using confederates in social experiments

Confederates are used in social experiments to help researchers study how people react in a controlled setting. A confederate is a person who seems like a normal participant but follows the researcher’s directions instead. This helps create conditions that feel natural while still keeping the experiment organized.

The study shown here uses a two-group design to test imitation. Researchers asked whether participants were more likely to copy a person with more power than a person with similar power. The experiment also shows how confederates can be used to create the social situation needed for the test.

Psychology studies often need large sample sizes. More participants can help the results better represent the population being studied and account for the margin of error in human behavior research. Human participants are also often easy to recruit, and experiments like this are quick and inexpensive to repeat. Although the demo shows the procedure with one participant, the results come from 156 participants.

from theory to design: the role of creativity in designing experiments

Creative Study Design in Social Psychology

Creative study design helps social psychology researchers test ideas about human thought, emotions, and behavior. Many research questions begin with a theory that suggests a possible explanation for everyday life. Some of those ideas are hard to study directly, so researchers need a careful plan to test them. One example is a theory about Facebook perception. Researchers asked whether a person’s image on Facebook is influenced by the appearance and comments of that person’s Facebook friends.

ethics in psychology research

Psychology Research Ethics and Aggression

Psychology research ethics guide how scientists study aggression while protecting participants. Researchers aim to make studies as real-world as possible, but they must also balance that goal with the best interests of the people taking part. Ethical choices begin early, when researchers decide how to measure or change a variable and then choose the safest option. Aggression is an important behavior to study because it can help explain interpersonal violence. A student who gets a poor grade on...

realism in experimentation

Mundane Realism in Lab Experiments

Mundane realism helps lab experiments feel like real life. It is used when researchers want a setting that matches how people normally behave. In some studies, the real world is the best place to observe behavior directly. For example, voting behavior is easier to study by watching people vote. But real-world research is not always ethical or practical. A lab gives researchers more control over the setting. That control helps them identify the exact variables that may influence an outcome. To...

Psychology Research Methods in Practice

Psychology research methods are shown through real experiments in this JoVE K12 collection. The pages let high school students watch studies from start to finish. They also show the experiments in their natural setting, inside the actual research process. The collection is useful because experimental psychology can be hard to connect to from a textbook alone. These videos give students exposure to more than a dozen topics they may not otherwise see. They can help bring abstract ideas to life...

pilot testing

Testing Stress Manipulations Before the Study

Pilot testing helps researchers check whether a manipulation works before they run the main study. In psychology, researchers need study experiences that are consistent, or reliable, and authentic, or valid. Pilot testing lets them try out a manipulation first and see if it produces the intended effect. This study focuses on acute stress, which is short-term stress caused during a task. The researchers compared three ways to create that stress. They tested static, a ticking clock, and a crying...

observational research

Behavior Clues in Psychological Research

Behavior clues can help psychologists study how people think and feel. Researchers may ask people directly, or they may watch what people do and look for signs of past behavior. These observations can add useful information, especially when self-reports are limited. Behavior is not always a perfect guide to a person’s real state. A person may smile and seem happy, but they could actually be annoyed and just trying to be polite. Science tries to move past self-view alone because a person’s own...

the simple experiment: two-group design

Testing Attraction with a Simple Experiment

A simple experiment uses a two-group design to test a cause-and-effect relationship between two variables. In this setup, a researcher compares two groups to see whether one factor changes the outcome. The video follows a research question about how physiological arousal, or excitement, influences perceived attraction. It shows how an idea becomes a testable idea and how a hypothesis is formed. The experiment variables are identified, and experimental conditions and controls are created. The...

the multi-group experiment

Testing Multiple Conditions in One Study

A multi-group experiment tests three or more conditions of the same independent variable. It lets researchers compare how each condition affects the outcome they measure. In this study, the conditions examine different interethnic ideologies and their effects on feelings about diversity and actions toward an out-group member. The video also shows how to tell levels in a variable apart and how to choose common study conditions. These can include placebo and empty-control conditions, which help...

within-subjects repeated-measures design

Repeated-Measures Study with Counterbalancing

A repeated-measures study uses the same participants in every condition of an experiment. In this design, each person receives every level of the independent variable. A simple example is a candy taste test, where each participant tastes and rates each type of candy. This psychology experiment looks at how motivational messages affect willingness to exert physical effort. The message types include hard work, self-affirmation, outcomes, and positive affect. Each participant reads all four...

the factorial experiment

Main Effects and Interactions in Factorial Designs

A factorial design uses two or more independent variables in one experiment. A 2 x 2 factorial design is a common example. It lets students see how more than one factor can shape an outcome at the same time. This experiment uses self-awareness and self-esteem as the two independent variables. It explores whether they affect the ability to decipher nonverbal signals. The design also shows how a factorial experiment differs from other designs and why it can be useful. A key part of this topic...

self-report vs. behavioral measures of recycling

self-report-vs-behavioral-measures-of-recycling

Behavioral Observation in Recycling Studies

Behavioral observation can give a more direct measure of recycling behavior than self-report. Self-report means asking people to describe their feelings, thoughts, or actions. In some cases, participants may not be fully honest. Observing what people actually do can help researchers measure behavior more accurately. This study uses a multi-group experiment to test whether feeling close to others leads to more positive attitudes toward environmental consciousness. Researchers measured the...

reliability in psychology experiments

Content Analysis and Reliability in Psychology

Reliability in psychology is important when researchers try to measure something that is hard to quantify. In content analysis, reliability helps show whether the measurement is consistent. The video uses a simple two-group design to show how this works. The example compares two cartoons, SpongeBob SquarePants and Caillou, to ask whether one has more inappropriate content than the other. The transcript also connects this topic to a recent Pediatrics study on 4-year-olds. That study found worse...

placebos in research

Yoga Expectations and the Placebo Effect

Yoga expectations can influence how researchers measure creativity. Clinical research often tests whether a treatment really works for a disorder or illness. A common challenge is that participants may already believe a treatment will help. Those expectations can affect the results and make it harder to tell what the treatment actually did. Yoga is a good example because it has many claimed benefits in the United States, including improved creativity. But it is not always clear whether yoga...

manipulating an independent variable through embodiment

Embodiment Effects in a Weight Experiment

Embodiment can affect how people think and act in an experiment. It is a research idea that says subtle physical experiences may influence thoughts without people realizing it. Researchers use this idea to see how a simple body sensation can change later judgments. Researchers often manipulate participants in one group so they have different thoughts, experiences, or feelings than people in other groups. Some manipulations are obvious, and others are subtle. In this study, the key physical...
