RESEARCH STUDY 4.1: Dr. Kushner is planning on conducting a study next semester. He is curious as to whether sleep deprivation is associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them. After the participants are awake for one minute, Dr. Kushner plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a sample SAT test. Dr. Kushner asks his participants to provide informed consent. Doing this is adhering to which principle of the Belmont Report? a. The principle of beneficence b. The principle of justice c. The principle of integrity d. The principle of respect for persons 7. RESEARCH STUDY 4.1: Dr. Kushner is planning on conducting a study next semester.

Question 1 reads, “I tend not to think about other people as much as I think about myself.” Question 2 reads, “I do not have a high opinion of myself.” Question 3 reads, “I think other people think I am really special.” Dr. Rodriquez calculates a correlation coefficient (r) to examine the relationship between Question1 and Question 2 and between Question 1 and Question 3. She finds a correlation coefficient of r =-0.73 between Questions 1 and 2 and a correlation coefficient of r = 0.74 between Questions 1 and 3. Which of the following is true of her findings? a. There appears to be good internal reliability in the scale. b. The correlation between Questions 1 and 2 and Questions 1 and 3 are in the same direction. c. The correlation between Questions 1 and 2 is much weaker than between Questions 1 and 3. d. The negative correlation between Questions 1 and 2 is bad for Dr. Rodriquez. 16.

Bothered by not having a good measure that he can give to clients to determine whether they are suffering from this condition, he creates a new measure of pathological gambling. The measure has 15 questions, and it takes 20 minutes to complete. Dr. Sheffield has now decided that he wants to test his measure on some university students (who some estimates say have a 6% prevalence rate of compulsive gambling). He has a group of 100 university students complete his measure. He also has them complete two other measures (one that measures addictive behavior in general and one that measures general attitudes toward gambling). He finds that his new measure is positively associated with each of these other measures. This procedure has provided evidence for the _____ of Dr. Sheffield’s measure. a. content validity b. predictive validity c. convergent validity d. discriminant validity 32.

RESEARCH STUDY 9.2: Dr. Finkel is a social psychologist who studies romantic relationships. Several researchers have found that there is a link between income and marital satisfaction (e.g., Dakin & Wampler, 2012).

He is confident that he cannot reasonably or ethically manipulate people’s income level, so he decides to use a multivariate design. He is also curious as to whether there is a causal link between these two variables or if two other variables (number of arguments and life satisfaction) can explain the relationship.

RESEARCH STUDY 9.3: Dr. Cheong is a clinical psychologist who is curious about how people deal with natural disasters (e.g., hurricanes, tornados, earthquakes). His previous research suggests that there is a relationship between how much people feel their emotional well-being was affected by the natural disaster and their likelihood of developing posttraumatic stress disorder (PTSD) symptoms. However, he is curious as to whether the effect of emotional well-being occurs because people receive different levels of social support. He conducts a study in which he asks 174 men and women affected by Hurricane Sandy (2012) to report on how their well-being was affected by the hurricane, the social support felt after the storm, and the number of PTSD symptoms. Dr. Cheong finds support for his proposed relationship. However, in examining his data more closely, he finds that the relationship between emotional well-being and PTSD symptoms is stronger for men than for women. Which of the following is the mediating variable in Dr. Cheong’s hypothesis? a. Emotional well-being b. PTSD symptoms c. Social support d. Participant sex 36.

There is a limit to the number of predictors that can be included in a regression. 38. Why is the statistical validity of a multiple regression design more complicated to interrogate than a bivariate design? a. Statistical significance of associations cannot be determined. b. Betas and rs share no similarities. c. These designs require more participants. d. It is harder to detect outliers. 39.

When determining mediation, how many steps are necessary? a. Two b. Three c. Four d. Five 41. Why would a researcher interested in making a causal claim NOT do an experiment? a. Experiments are very expensive and the researcher might not have grant funding. b. There may be ethical limitations of manipulating a variable. c. Laboratory space is required for experiments and the researcher might not have a lab. d. Experiments take longer to do than other types of studies. 42. If an experiment cannot be done for practical or ethical reasons related to manipulating the variable of interest, which of the following events should happen? a. The study should not be conducted at all. b. The researchers should wait until the experiment can be done. c. A longitudinal correlational design could be done instead. d. The IRB can grant a waiver of review to conduct the study anyway. 43. A criterion variable is also known as a(n) _________ variable. a. predictor b. independent c. control d. dependent 44.

Such topics as the link between media and aggression and smoking and lung cancer have been studied with a variety of methods and by a variety of researchers and have all reached similar conclusions. This is an example of which of the following? a. Hypothesis generation b. Third variable problems c. Multiple-regression designs d. Pattern and parsimony 48. Why is it problematic when journalists only report on a single study? a. It can make journalists look bad. b. It can lead people to think journalists are scientists. c. It can lead people to value one study over decades of previous research. d. It can cause people to interrogate a study’s validities. 49. Why should journalists report on the previous body of research when writing about a newly published scientific study? a. To highlight pattern and parsimony in scientific research b. To demonstrate that they have a background in science c. To make it easier for their readers to determine that the story is credible d. To prove to their editors that readers will be interested in the story 50. When examining the results of a multiple regression, which of the following should be compared to determine which predictor variables have the largest relationship to the criterion variable? a. b values b.
