Dr. Sanders is interested in how people understand feedback about their performance and incorporate it into their view of themselves. She has large groups of participants take a bogus personality test and then, in front of the group, tells each of them that they either did very well, average, or very poorly. She also tells them that their scores on the test accurately predict future life and success. Dr. Sanders then has the participants write a short paragraph describing their personal strengths and weaknesses. At the end of the study, the group turns in their paragraphs and is excused. At no time does Dr. Sanders inform them that the test and feedback were actually false. In fact, she never tells them about the nature of the study. Dr. Sander's study violates which ethical standard? A. Protection from harm. B. Informed consent. C. Confidentiality/privacy. D. Debriefing.
A. Protection from harm.

The researched carefully selects and approves each participant for the study. C. The institution in which the study will be has approved the study. D. All parties in a study--including researchers, participants, and institutional administrators-- know the study's hypothesis.
A. The participant knows his or her role in the study and understands its risks and benefits.
Case 2: Flirting Behavior Study In a recent study, social psychologists went into a bar to try to determine whether men or women flirted more. The procedure involved secretly observing the behavior of individuals, and counting the number of their flirtatious actions. The participants were not aware that they were being observed, and no names were ever recorded. Do you think this experiment should have been allowed according to the ethics guidelines outlined earlier? And if not, why? A. Yes, it should be allowed. B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. D. No, it should not be allowed because it violates the rule that participants' privacy must be protected. E. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
A. Yes, it should be allowed. It would be allowed. Even though the participants were not notified about the experimental procedures, public behavior does not require informed consent; the procedures, did not cause harm to the participants; and the since names were not recorded, it did not violate their privacy.
Case 3: Attraction Study Social psychologists wanted to learn whether a man would be more attracted to a woman when he met her in a dangerous situation that would produce a physiological arousal. Prior to the experiment, the men were told they would be interviewed by a researcher. They were also told that they could quit the study at any time and were assured that all of the data would be confidential. All of the men freely agreed to participate. In the study itself, the men in the control group were interviewed by a female researcher in a sterile laboratory setting. In contrast, the men in the experimental group were interviewed by the same female researcher while standing on a narrow, wobbly bridge that spanned a raging river. In this latter case, the men were in no real danger, although the bridge certainly induced anxiety in some. After the experiment, men in both groups were informed about the real purpose of the investigation. If this experiment were conducted today, would a committee approve it? And if not, why? A. Yes, it should be allowed. B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. D. No, it should not be allowed because it violates the rule that participants' privacy must be protected. E. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
A. Yes, it should be allowed. This experiment would be allowed. Even though participants were not notified about the entire purpose of the experiment, this omission was justifiable.
What does IRB stand for? A. Institutional Research Board. B. Institutional Review Board. C. Informational Review Board. D. Individual Research Board.
B. Institutional Review Board
Dr. MacLeod is the chair of an institutional review board at a local university. He recently received a research proposal from Dr. Portree. Dr. Portree wants to conduct a study in which she tells graduating seniors that they have failed all of their classes and will not be graduating college to see how college students cope with stress. She wants to randomly choose enrolled students at the university to send her "failing notices" and she points out that she cannot have them sign a consent form because if they knew that they are in a research study they might not believe that they are failing and it will ruin the results of the study. Should Dr. Macleod allow Dr. Portree to conduct her study with the university students? A. Yes, the forward progress of science, especially in the area of stress and health is very important. He should let her conduct her research. B. No, He should not let her conduct her research because it violates the ethical rule that participants must freely choose to participate in a study and must be free to withdraw at any time. C. No, it should not be allowed because it violates the rule that participants' privacy must be protected. D. Yes, he should let her conduct her research. Although being told about not passing their classes and flunking out of college would be severely stressing, it would not likely rise to the level of violating the rule that participants must be protected from undue physical or mental harm.
B. No, He should not let her conduct her research because it violates the ethical rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
Case 5: Cookie Research A market researcher wants to discover which cookie recipe is most popular among college students. However, the researcher does not want to reveal to the students that he works for a food manufacturer. The researcher invites 50 volunteer participants into his laboratory, and tells them that they are going to fill out a survey which will assess their knowledge of political issues. He promises that their data will be kept confidential, and that they can quit at any time.As students complete the survey, the researcher offers them two types of cookies, free of charge. He keeps track of which cookie the participants prefer by counting the number of each kind that are eaten. Afterward, the researcher thanks the participants and sends them home. If this experiment were conducted today, would a committee approve it? And if not, why? A. Yes, it should be allowed. B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. D. No, it should not be allowed because it violates the rule that participants' privacy must be protected. E. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. The committee might disallow this procedure because the researcher never reveals the real purpose of the experiment. In some cases, a research committee will permit a limited amount of deception during the experiment if it is necessary to maintain the integrity of the investigation. However, in this case, the experimenter should reveal the real purpose of the experiment during the debriefing.
John is planning on conducting an experiment to see how men and women differ in geography performance. After describing the study to the participants, he gives them a written geography test. To make sure he does not mix up his data, he has each person write their name at the top of their test.

Professor Cognition is examining how time delays affect memory performance. He decides to use students in his psychology course as his subjects. During a class session, he tells the students about the study. They will take a memory test in class and then again, an hour later. As an incentive, he informs the class that those who are willing to participate will receive 10 points extra credit. Those not willing to participate will have 10 points deducted from their overall course grade. The students who decide to participate complete the two memory tests anonymously and then are explained the basis for the experiment. Professor Cognition is violating which ethical standard? A. Informed consent. B. Voluntary participation. C. Confidentiality/privacy. D. Debriefing.
B. Voluntary participation.

Case 1: Little Albert In this a famous study from 1924, John Watson wanted to explore what causes children to develop phobias. After explaining the purpose of the study to the child's mother, he exposed a child to a friendly white rat. Each time the boy touched the rat, Watson made a loud noise. Eventually, the child developed a fear of the rat. He published the research referring to the baby with a generic first name. This research was conducted before the use of standards of ethical research. However, if this experiment were conducted today, would a committee approve it? A. Yes, it should be allowed. B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. D. No, it should not be allowed because it violates the rule that participants' privacy must be protected. E. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. This is the best answer. The procedures clearly may have resulted in psychological harm to the child, and if the experiment were proposed today, it would be disallowed.

Case 4: Food Consumption, Soda and Fruit Drinks Study A researcher wants to determine whether college students consume more food when the food is accompanied by a cola beverage or by a fruit drink. The researcher explains the goal and the procedure to her introductory psychology students and assigns them to attend a party at her home. All of the food and drinks are provided free of charge. One group of students is assigned to drink cola, and the other group is assigned to drink a fruit beverage. An assistant observes the students and counts the amount of food each of them consumes. All of the students in her class are required to participate in order to pass her class, but all of the data are kept confidential. If this experiment were conducted today, would a committee approve it? And if not, why? A. Yes, it should be allowed. B. No, it should not be allowed because it violates the ethical rule that participants must be informed about the nature of the experiment and its procedures. C. No, it should not be allowed because it violates the rule that participants must be protected from undue physical or mental harm. D. No, it should not be allowed because it violates the rule that participants' privacy must be protected. E. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time.
E. No, it should not be allowed because it violates the rule that participants' privacy must be protected. No, it should not be allowed because it violates the rule that participants must freely choose to participate in a study and must be free to withdraw at any time. This procedure would not be allowed because the instructor required the students to participate, and therefore they were not free to decline. Many colleges request or even require students to participate in research as part of their training in psychology. However, if students do not want to participate in a particular study (or any studies), they have the right to participate in some alternative educational activity such as writing a short paper.

Dr. Adriana conducts a study to determine if players who wear a new type of soccer uniform made from a specifically designed fabric will perform better in soccer matches. She recruits a professional soccer team to participate in her study. She randomly assigns half of the men to wear the new-material uniforms made in the color blue and the other half to wear old-material uniforms made in the color red. Although the men know about the test, they are not told which one of the two uniforms is made from the new material. They are asked to wear their assigned uniforms and score as many goals as possible in a game against one another. Dr. Adriana notes the number of goals scored. Ultimately, the players who are wearing the old uniforms score more goals, and therefore, win the game. Dr. Adriana speculates that the new uniforms are not more beneficial to performance than the old uniforms, but she decides to conduct the test a few more times. What was the control group in Dr. Adriana's study?
The players who wore red uniforms made from the old material.
Why do we draw on small subsets of a population to collect data?
They give an accurate representation of the entire population. Too much effort to collect data from an entire population.
