1. Define ethical behavior in research.
<ol>
	<li>Ethics are a collection of moral standards and principles that guide the decisions we make. They essentially tell us what we should do. What the researcher could do is different from what they should do.</li>
	<li>Cost-Benefit Analysis: To know if the research should be conducted, the researcher needs to make sure the benefits outweigh the costs or risks of harm.&#160; This can be accomplished by increasing participants&#8217; benefits and/or lowering the costs.</li>
</ol>
2. Define key variables.
<ol>
	<li>Create an operational definition (i.e., a clear description of exactly what a researcher means by a concept) of negative feedback.
	<ol>
		<li>For the purposes of this experiment, negative feedback could entail a number of different forms, e.g., medical results that indicate the participants have a disease, a diagnostic test that indicates they have low IQs, harsh commentary on their physical appearance, or severe criticism on their written work.</li>
		<li>Applying cost-benefit analysis, providing severe criticism on written work is the least harmful type of negative feedback to give to the experiment participants. Therefore, ethical behavior dictates that this is the type of negative feedback that should be used.</li>
	</ol>
	</li>
	<li>Create an operational definition (i.e., a clear description of exactly what a researcher means by a concept) of aggression.
	<ol>
		<li>For purposes of this experiment, aggression could involve a number of different behaviors, e.g., being verbally abrasive to the participant, physically pushing the participant, administering an electrical shock to the participant, or giving the participant a foul-tasting drink.</li>
		<li>Applying cost-benefit analysis, the noxious beverage incurs the least amount of harm to the participant (and is something that has been used in previous research). Therefore, ethical behavior dictates that this is the type of aggression that should be used.&#160;</li>
	</ol>
	</li>
</ol>
3. Conducting the Study
<ol>
	<li>Provide participants with informed consent, a brief description of the research, a sense of the procedure, an indication of potential risks/benefits, the right to withdrawal at any time, and a manner to get help if they experience discomfort.</li>
	<li>Direct participant to write a paragraph that describes a day at the beach.</li>
	<li>Once complete, inform participant that the paragraph will be delivered to another researcher (the evaluator) in the next room for evaluation that should take about 5 min.</li>
	<li>Once in the other room, the researcher randomly determines which of the two types of feedback the participant receives by rolling dice. For an even number, give negative feedback and for an odd number, give neutral feedback.
	<ol>
		<li>For negative feedback, mark the paragraph, in red ink, with several negative comments, e.g., &#8220;This is ridiculous!&#8221;; &#8220;Are you sure this even makes sense?&#8221;; &#8220;very awkwardly phrased&#8221;; &#8220;too obvious!&#8221;; &#8220;really????&#8221;; &#8220;not very imaginative&#8221;; and &#8220;needs a complete rewrite.&#8221;</li>
		<li>For neutral feedback, return an unmarked paragraph to the participant and explain that the other researcher was too busy to comment.&#160;</li>
	</ol>
	</li>
	<li>Return the paragraph, with feedback from the evaluator, to the participant.&#160; Suggest they read it over while part 2 of the study is prepared.</li>
	<li>Prepare 5 beverages (highly sugared water, lemon water, plain water, vinegar in water, and hot sauce in water) that provide a range of pleasant to unpleasant tastes.</li>
	<li>Prepare index cards with a number on one side and description on the other (1 = sugar water, 2 = lemon water, 3 = water, 4 = vinegar water; 5 = hot sauce water).</li>
	<li>Return to participant with the 5 beverages, with labels, arrayed on a platter.
	<ol>
		<li>Explain to the participant what each beverage contains.</li>
		<li>Tell the participant to choose one beverage for the evaluator&#8217;s friend, in the other room, to consume.</li>
		<li>Record the number associated with the chosen beverage. This number correlates to the level of aggression displayed by the participant.</li>
	</ol>
	</li>
</ol>
4. Debrief: For further ethical reasons, it is necessary to debrief the participant carefully as to the nature of the experiment.
<ol>
	<li>&#8220;Thank you for participating. In this study, I was trying to determine if receiving negative feedback on your paragraph would lead you to scapegoat, or take out your frustration on the evaluator&#8217;s friend by selecting a more distasteful beverage. We believed that negative evaluations would lead to retaliation toward the friend in terms of more distasteful drink choices. Do you have any questions?&#8221;</li>
	<li>Explain explicitly why deception was necessary for the experiment.
	<ol>
		<li>&#8220;We want to tell you about the deception we used in this study. We used deception because it is important that we get a natural performance, not one that the participant feels is expected. 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&#8217;s perceived expectations. To eliminate this problem it was necessary for us to tell participants a cover story for the experiment. The cover story in this experiment was that your essay was truly being evaluated. However, the feedback we gave had nothing at all to do with what you wrote. We also mislead you to believe that there was an evaluator and his friend in the next room. In reality, the researcher gave you the feedback and there wasn&#8217;t anyone in the next room. Because of the nature of the deception, it is quite natural for participants to not realize that they were being deceived.&#8221;</li>
	</ol>
	</li>
</ol>

This two-group experiment shows how researchers can study sensitive topics in an ethical way that minimizes harm to participants, while still allowing participants to engage in an aggressive behavior.
As they study human behavior, psychologists often seek to analyze undesirable and troubling behavior. For example a recent study in Psychology of Popular Media Culture found that when video-game players lost a game, they were more likely to act aggressively by trash-talking.1 ...

When a researcher finds an interesting topic to study such as aggression, the goal is often to study it in a way that is as true to life as possible. However, researchers must act in an ethical manner.&#160; To do this, they must balance their research goals with the best interests of the participants. Ethics often enter into the planning process when researchers identify all of the ways they can manipulate or measure a variable, but then make their final decision based on how they should manipulate or measure a variable.
After receiving a poor grade on a test or paper, a college student may appear to take it out on (i.e., act in an aggressive manner toward) their roommates by being mean or nasty, screaming, throwing things, or even becoming physically violent. Aggression is an important human behavior to study and understand due to the implications it has for interpersonal violence. However, for safety reasons, a study cannot expose participants to the risk that serious types of violence presents. As a result, researchers must identify similar but benign behaviors that can help us understand more aggressive behaviors without harming participants.
This video uses a two-group experiment to see if people really take out their anger on others even though the others are not responsible for the original problem. Specifically, it examines whether negative feedback leads to aggression while considering key ethical issues such as harm to participants, costs vs. benefits, informed consent, and debriefing.
Psychological studies often use higher sample sizes than studies in other sciences. 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. In this video we demonstrate this experiment using just two participants, one being the evaluator. However, as represented in the results, we used a total of 245 participants to reach the experiment&#8217;s conclusions.

The data were collected from 245 participants. Recall that the aggression scale was calculated on the number assigned to each of the drinks, which varied in levels of distasteful flavor. A t-test for independent means was run to compare the negative and neutral feedback conditions to determine how they influenced aggression. The results indicated that participants who received the negative feedback generally chose more noxious drinks for the innocent person in the other room (the friend of the evaluator), which is an ind...

When a researcher finds an interesting topic to ...

Sensitive topics in research require careful planning to uphold ethical behavior- the moral standards that guide decision-making.Designing studies in an ethical manner requires a balancing act between the benefits of the research and the costs or risk of harm to participants.This decision process is referred to as a cost-benefit analysis, in which the study?s intent outweighs the high costs or risks of harm for those involved.By applying ethical principles, this video demonstrates how to design, perform, analyze, and interpret an experiment about interpersonal aggression. Importantly, researchers study anger towards others without resorting to physical harm by incorporating more benign forms of aggressive behavior.For this experiment, consider two sensitive topics, negative feedback and aggression, that require cost-benefit analyses to demonstrate ethical compliance.Negative feedback towards participants might entail a number of different forms, including: medical results that indicate disease, a diagnostic test that indicates low IQ, harsh commentary on physical appearance, or severe criticism on written work.Aggression could involve a number of behaviors, such as being verbally abusive to the participant, physically pushing the participant, administering an electrical shock to the participant, or giving the participant a foul-tasting drink.Here, the experiment will focus on providing severe criticism on participant?s written work.Using a two-group design, all participants write a paragraph about a day at the beach. One group receives negative feedback in the form of negative comments, whereas the second group receives neutral feedback, or no comments.After receiving criticism, participants are asked to choose a beverage for their paragraph evaluator?s friend. The beverage choice correlates to the level of aggression displayed by the participant.The hypothesis of the experiment is negative feedback induces aggression that would be taken out on another individual.Thus, those who receive negative comments are expected to retaliate and choose more distasteful drink choices than those who receive no comments.To conduct the experiment, gather the informed consent and final debriefing papers, a black pen, and a blank piece of paper. In a different room, you will need: dice, a red pen, index cards, 5 cups of water, a tray or platter, and portions of sugar, lemon juice, vinegar, and hot sauce.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.With the participant sitting at a desk, ask them to write a brief paragraph that describes a day at the beach. After the participant finishes, inform them that another researcher will evaluate the paragraph over the next 5 min.Once in another room, roll dice to randomly determine the kind of feedback the participant receives. Assign negative feedback for an even number, and write comments on the paragraph with a red pen. If the dice roll results in an odd number, assign neutral feedback, and do not make any marks on the page.After providing feedback, return the paragraph to the participant. Suggest that they read over the comments when you leave the room to set-up the next phase of the experiment.While the participant waits, prepare five different beverages that range from pleasant to unpleasant tastes: highly sugared water, lemon water, plain water, vinegar in water, and hot sauce in water.Then, label five different index cards with a number on one side and description on the other. Arrange each pair on a platter.After arranging the platter, carry it into the room with the participant. Explain what each beverage contains. Instruct them to choose one beverage for the evaluator?s friend to drink in the other room. Record the number associated with the chosen beverage.At the conclusion of the experiment, debrief participants and explain why deception was necessary for the experiment.To analyze how aggressive behavior is expressed after feedback, average the numbers recorded for the chosen beverages in each condition.The data are then graphed by plotting the mean number in each condition. In this experiment, participants who received negative feedback retaliated and chose a more distasteful beverage for the evaluator?s friend than those in the neutral group who did not receive any feedback.Now that you are familiar with how psychologists study sensitive topics in an ethical way, let?s take a look at how other researchers are mindful of moral standards that promote safe alternatives for studying troubling and undesirable behaviors.A recent study found that when video game players lost a game, they were more likely to act aggressively by ?trash-talking.? The researcher considered the ethical implications of the design because trash-talking is less risky than physical aggression.This study uses a social test that reliably induces a stress response in participants.Physiological measures, such as skin conductance, heart rate and stress hormone levels, are obtained non-invasively through simple monitoring equipment and saliva samples.Thus, this experiment provides an ethical alternative to painful physical stressors like treadmill running or cold pressor test.Facing numerous ethical concerns, animal researchers use: within-group designs to reduce the number of unnecessary subjects, behavioral tasks to obtain ethological responses, and administer pharmaceutical agents to minimize pain and suffering.You?ve just watched JoVE?s introduction to Ethics in Psychological Research. 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!?

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 a test or paper may seem to take that frustration out on roommates by being mean, yelling, throwing things, or even becoming physically violent. Because a study cannot safely expose people to serious violence, researchers look for similar but harmless behaviors that still help them understand aggression.

The experiment in this lesson uses a two-group design to test whether negative feedback leads to aggression toward someone who did not cause the original problem. It also highlights key research ethics topics, including harm to participants, costs versus benefits, informed consent, and debriefing, which is the explanation given to participants after the study.

Psychology studies often use larger sample sizes than studies in other sciences. More participants help better represent the population being studied and reduce margin of error in research on human behavior. Although the demonstration uses only two people, including an evaluator, the results are based on a total of 245 participants.

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.

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...

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...

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...

experimentation using a confederate

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...
