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 reported in the attached Table #1.

Example #2: 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 following results in response to the number of words remembered. Group A (Happy) Group B (Sad) Group C (Neutral) Number of Words Remembered 16 14 9 Groups A and B vs. Group C Statistically significant difference d = .36 Group A vs. Group C Statistically significant difference d = .30 Group B vs. Group C Statistically significant difference d = .41 Group A vs. Group B No statistically significant difference d = .09 E8: Which of the following is a dependent variable in Dr. Lonsbary's study?

E10: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink.

She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Which of the following threats to internal validity will Dr. Bloedorn NOT be worried about?
Testing effect NOT: Attrition Demand characteristics NOT: Placebo effects

The beta value for number of arguments may no longer be statistically significant.
E10: Imagine that in Dr. Schulenberg's study, he notes that all of the students do extremely well on the midterm exam. When he looks at the results of the final exam, he notices that all the students' exam scores went down. Which of the following pattern of results would suggest that there is a threat to internal validity?
The final exam scores were equally low in both groups.
E8: Example #1: 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. DV: Marital Satisfaction Variable Beta (b) Significance (r) Income .69 .03 Number of arguments -.73 .01 Life satisfaction .13 .81 Consider Example #1 in the attached file.

E4: Example #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.

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?

E5: Example #1: 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 is concerned whether her measure will really measure narcissism or if it will measure some other related concept. She is concerned about the scale's ___________:
