Research Methods in Psychology Questions and Answers

A health psychologist is interested in the potential effect that a change in career focus can have on cardiovascular disease for those in high stress jobs. She chooses to study divorce lawyers (a population that averages a mean systolic blood pressure of 142 with a standard deviation of 13) and measures the blood pressure of 23 former divorce lawyers who switched to environmental law. Those 23 lawyers have a mean systolic blood pressure of 131. If all divorce lawyers switched to environmental law, what would you expect the mean systolic blood pressure to be with 99% confidence? Question 1 What is your point estimate for the mean systolic blood pressure for divorce lawyers who switch to environmental law?

Consider the following research study: Participants were recruited to participate in a study to understand the impact of external cues and emotion. Although participants were fully informed of the study protocols and all gave consent, due to the nature of the study they were led to believe that the experiment was related to eye sight. Male participants were injected with epinephrine, a hormone that induces arousal including increased heartbeat, trembling, and rapid breathing. The research participants were told that they were being injected with a new medication to test their eyesight. The first group of participants was informed the possible side effects that the injection might cause while the second group of participants were not. The participants were then placed in a room with someone they thought was another participant but was actually a confederate (an actor) in the experiment. The confederate acted in one of two ways: euphoric or angry. Participants who had not been informed about the effects of the injection were more likely to feel either happier or angrier than those who had been informed. Would this study be considered ethical by the standards upheld by Institutional Research Boards (such as IRB or IACUC)? Select the best answer. Yes, it would be ethical. No, it would not be ethical.

Which of the following is an inaccurate statement about case studies? Select the best answer. allows researchers to gather data from larger samples than may be afforded by other research methods often used when studying individuals who are interesting to researchers because they have a rare characteristic difficult to generalize observations from this type of research to the larger population as a whole

Which of the following is considered a weakness of a case/clinical study? Select the best answer. This design can be difficult to narrow down the participant pool to select a sample from. Some case studies are not scientific, such as Freud who used case studies to develop many of his theories. The data collected is surface in nature.
