Dr. Anderson is a nutritionist who helps clients lose weight prior to surgery. She is working with W. J., a male client who is planning on undergoing a heart transplant. He currently eats more than 3,500 calories a day and has been asked by his doctor to cut the number of calories to about 1,800 (400 for breakfast, 600 for lunch, and 800 for dinner). She is curious as to whether a food journal will help W. J. reduce the number of calories he eats. A food journal is used to record everything a person eats to help patients be more aware of what they're eating. W. J.'s wife also recorded the food he consumed at each meal to have complete data before introducing the journal. Dr. Anderson decides to phase in the food journal gradually, initially only having W. J. record what he ate at breakfast during the first three days after baseline (days 4-6). During days 7-9, the journal is used at lunch, too, and during days 10-12, it also is used during dinner. The data for Dr. Anderson's study are below. What type of small-N design has Dr. Anderson used with W. J.? A. Multiple-baseline design B. Reversal design C. Stable-baseline design D. Interrupted time-series design

Dr. Lonsbary is a cognitive psychologist who is curious about how mood affects memory. She recruited 60 high school students and divided them into three groups. Group A listened to a 5-minute piece of music intended to make them feel happy ("Happy" by Pharrell). Group B listened to a 5-minute piece of music intended to make them feel sad (a song titled "Home Is Such a Lonely Place" by Blink-182). Group C listened to no music and instead was asked to sit quietly for 5 minutes (thought to make them feel neutral). When a participant would come to her laboratory, Dr. Lonsbary would greet the participant and then ask him or her to roll a six-sided die. Participants who rolled a 1 or 2 were assigned to Group A. Participants who rolled a 3 or 4 were assigned to Group B. Participants who rolled a 5 or 6 were assigned to Group C. The participants were then given an unlabeled CD to listen to based on their group assignment. The CD contained either the song selection or 5 minutes of silence. They were then escorted into a different room, where they were greeted by a research assistant who conducted the experiment. The research assistant sat the participants in front of a computer screen and told them that a list of 25 words would be displayed on the screen. They were instructed to listen to the CD with headphones while trying to memorize the list of words. All participants were given the same list of 25 common words to remember (e.g., desk, gray, plane, car, mask). When 5 minutes had passed, the screen displayed a question asking them whether they felt happy, sad, or neutral. After the participant responded, a new screen was displayed asking them to type in all the words they could remember from the list of 25 words. All participants were given 3 minutes to type the words they remembered. Afterward, the participant was thanked and dismissed. In response to the mood question, a majority of Group A participants said they were happy, a majority of Group B participants said they were sad, and a majority of Group C participants said they were neutral in their mood. Dr. Lonsbary found the results in the table below. Dr. Lonsbary's study (above) asked participants to report on their mood before completing the memory test. Her decision to include this step was done to address the study's _________ validity. A. construct B. statistical C. external D. internal
A
Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Donal scale. 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 Question 1 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 negative correlation between Questions 1 and 2 is bad for Dr. Rodriquez. C. The correlation between Questions 1 and 2 is much weaker than between Questions 1 and 3. D. The correlation between Questions 1 and 2 and Questions 1 and 3 are in the same direction.

Dr. Sheffield is a clinical psychologist who specializes in treating pathological gambling. Pathological gambling is defined as being unable to resist impulses to gamble. 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. Figure shows scatterplot with upward-sloping trend line A. convergent validity B. content validity C. predictive validity D. discriminant validity

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. Participant sex B. Social support C. PTSD symptoms D. Emotional well-being
B
Dr. Cyril conducts a simple random sample of 500 men who became fathers for the first time in the past year.

Dr. Elder was interested in the way people recognize objects as members of categories. For example, what makes us recognize a dog as being a dog and not a cat? More specifically, he was curious as to whether people think about categories in a more complex way if they contemplate an "opposite" category first. For example, does a person think differently about the category of "southern" if they first think about the category of "northern"? He is also curious as to whether people categorize differently if they are exposed to category members compared with generating category members. Dr. Elder has four groups of participants (with 30 people in each group). In Group A, participants were told to cut out pictures of dogs and cats from magazines. In Group B, participants were told to cut out pictures of just dogs from magazines. In Group C, participants were told to draw pictures of cats and dogs. In Group D, participants were told to draw pictures of just dogs. After doing this for 30 minutes, participants in all groups were asked to list the attributes that define the "dog" category. Having a higher number of attributes listed was considered to be an indication of thinking about the category in a more complex way. The results of his study are below. Cut out | Draw Dogs 7 | 6 Both 15 | 9 In graphing the difference between the differences, which of the following values would Dr. Elder use? A. 6.5 B. 9 C. 12 D. 7.5

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. Imagine that Dr. Kushner is a clinical psychologist who volunteers his time at a local prison counseling several inmates. Because of his connections there, he is considering using prisoners as his participants. Why is this choice potentially problematic? A. More prisoners may want to participate than Dr. Kushner can actually study. B. According to the Belmont Report, prisoners are entitled to special protection. C. Prisoners do not make good participants since they may not tell the truth. D. Prisoners are unable to give informed consent.

In previous studies, Dr. Schulenberg has established that finding meaning in one's everyday work activities can lead to greater success in the workplace (e.g., productivity, creativity). He is curious as to whether this can happen in the college classroom. Specifically, he is curious whether finding meaning in one's classroom experience can lead to greater academic performance. In the spring semester, he has his teaching assistant randomly assign half the class to write a paragraph each class period about how the material has meaning for their lives (meaning group). The other half writes a paragraph about what they did to prepare for class (preparation group). He does not know which of his students are writing which paragraph, and the students are not aware they are responding to different writing assignments. To measure academic performance, he gives the students a midterm essay exam and a final exam. Which of the following aspects of Dr. Schulenberg's study allows him to prevent observer bias? A. Having his teaching assistant assign students randomly to the two groups B. Ensuring the person grading the exams is unaware of each student's writing group C. Keeping his students unaware of which type of essay they are writing D. Grading the exams himself (a Ph.D.) instead of having his teaching assistant (a college senior) do it

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). Dr. Finkel is curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of marital satisfaction. 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. He measures his three variables in a sample of 124 married couples recruited from a local community center. Below are his results. Variable Beta Significance Income .69 .03 Number of arguments -.71 .01 Life satisfaction .13 .81 Which of the following can be concluded based on the results of Dr. Finkel's study? A. As the number of arguments a couple has increases, their marital satisfaction increases as well, controlling for income but not life satisfaction. B. Income is a stronger predictor of martial satisfaction than either the number of arguments or life satisfaction. C. The beta for the relationship between life satisfaction and marital satisfaction is significantly different than zero. D. The relationship between life satisfaction and marital satisfaction has the weakest effect size of all of the results.

There is not a statistically significant association between the two variables. B. An association of that size between number of friends one has and experience of daily stress is pretty likely assuming the null hypothesis is true. C. She cannot reliably predict a study participant's experience of daily stress from the participant's number of friends. D. Effect size could not be calculated.

Dr. Lonsbary is a cognitive psychologist who is curious about how mood affects memory. She recruited 60 high school students and divided them into three groups. Group A listened to a 5-minute piece of music intended to make them feel happy ("Happy" by Pharrell). Group B listened to a 5-minute piece of music intended to make them feel sad (a song titled "Home Is Such a Lonely Place" by Blink-182). Group C listened to no music and instead was asked to sit quietly for 5 minutes (thought to make them feel neutral). When a participant would come to her laboratory, Dr. Lonsbary would greet the participant and then ask him or her to roll a six-sided die. Participants who rolled a 1 or 2 were assigned to Group A. Participants who rolled a 3 or 4 were assigned to Group B. Participants who rolled a 5 or 6 were assigned to Group C. The participants were then given an unlabeled CD to listen to based on their group assignment. The CD contained either the song selection or 5 minutes of silence. They were then escorted into a different room, where they were greeted by a research assistant who conducted the experiment. The research assistant sat the participants in front of a computer screen and told them that a list of 25 words would be displayed on the screen. They were instructed to listen to the CD with headphones while trying to memorize the list of words. All participants were given the same list of 25 common words to remember (e.g., desk, gray, plane, car, mask). When 5 minutes had passed, the screen displayed a question asking them whether they felt happy, sad, or neutral. After the participant responded, a new screen was displayed asking them to type in all the words they could remember from the list of 25 words. All participants were given 3 minutes to type the words they remembered. Afterward, the participant was thanked and dismissed. In response to the mood question, a majority of Group A participants said they were happy, a majority of Group B participants said they were sad, and a majority of Group C participants said they were neutral in their mood. Dr. Lonsbary found the results in the table below. Dr. Lonsbary's colleague, Dr. Chavis, recommended randomly assigning the participants to the three groups. His recommendation was designed to avoid which of the following? A. A practice effect B. An order effect C. A carryover effect D. A selection effect

From which part of an APA-style introduction was the following paragraph from the article by Schultz, Gaither, Urry, and Maddox (2015) most likely copied? Explain your answer. "Although the United States is becoming increasingly racially and ethnically diverse (U.S. Census, 2012), racial bias against Black Americans is a continuing problem (Pearson, Dovidio, & Gaertner, 2009). As such, it is important to identify effective ways to reduce racial bias—particularly that of White Americans, who represent the country's most dominant racial group. Intergroup contact across racial groups has been proposed as one effective candidate in this regard (Pettigrew & Tropp, 2006). In theory, intergroup contact promotes meaningful interaction and conversation across racial and ideological boundaries, providing the opportunity for individuals to learn the perspectives and opinions of others. Without quality contact and communication, much of our behavior toward outgroups stems from our (mis)conceptions of them, thus maintaining the status quo (Shelton & Richeson, 2005)" (p. 392).
