RESEARCH STUDY 5.2: 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 decided to test the discriminant validity of his new measure. He has a group of first-time Gamblers Anonymous (GA) attendants complete his measure and finds that they score higher than a group of people who do not attend the group. Which of the following results would provide evidence for discriminant validity?

He finds that the measure of gambling is not correlated with a measure of life satisfaction in the same two groups of people.

RESEARCH STUDY 3.3: Anton and his friends are discussing a study he read about in his developmental psychology class. In the study, the researcher made the claim that most middle school students who are bullied have low self-esteem. Clarissa questions the study, saying, "I am not sure that I am convinced. I am not sure you can really measure being bullied." Quinn also questions the study, saying, "Which middle school students did they study? I am curious if they included both private and public school students." Manish also is curious about the study, asking, "I wonder how strong the relationship is between bullying and self-esteem. Could you predict one from the other?" Why should Anton NOT interrogate the internal validity of the study?

because the study's claim is an association claim

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?

The principle of respect for persons

RESEARCH STUDY 1.1: Deci and Ryan (1985, 2001) have proposed that there are three fundamental needs that are required for human growth and fulfillment: relatedness, autonomy, and competence. Susan predicts that students who have these needs met in their psychology class feel happier and more satisfied with the class. She collects data and finds that students who feel more related and competent do feel happier but that feeling more autonomous does not seem to matter. Susan thinks that maybe autonomy is only necessary when people are in situations in which they are not being evaluated. Susan's prediction that students who have all three needs met will experience greater satisfaction with their psychology class is an example of which of the following?

A hypothesis

RESEARCH STUDY 10.2: Dr. Dormeur studies sleep and sleep disorders. She is curious as to whether technology exposure before bedtime causes people to fall asleep more slowly. She recruits a sample of 60 middle-aged women from a local church who reported no history of sleep problems. She creates three conditions. All participants come to the sleep lab for three nights in a row and experience all three conditions. In the first condition (A), participants were asked to play an online game (Candy Crush) on an iPad for 10 minutes prior to going to bed. In the second condition (B), participants were asked to read an article using an iPad that discussed tricks and tips for improving one's score on Candy Crush (which took about 10 minutes). In the third condition (C), participants were asked to read a newspaper article about the inventor of Candy Crush (which took about 10 minutes). With the use of an electroencephalograph (EEG), the researcher measures how long it takes participants to fall asleep. Dr. Dormeur was concerned that asking participants how long it took them to fall asleep would lead them to suspect that was the purpose of the study. Her decision to measure how long it took participants to go to sleep using the EEG instead of self-report was meant to decrease which of the following?

Demand characteristics

Vanessa claims that she sleeps better when she falls asleep to music. She has a comparison group because she has noticed that she does not listen to music every night, only when she remembers to charge her iPod. She typically remembers to charge her iPod on nights when she is able to finish studying earlier. What problem do you see in Vanessa's reasoning about sleeping better to music?

Vanessa may be sleeping better because she is less distracted by studying/going to bed sooner

RESEARCH STUDY 5.2: 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.

However, his graduate student does not conduct the study and instead provides Dr. Kushner with invented results that support his hypotheses. This is known as which of the following?

Data fabrication

RESEARCH STUDY 10.1: 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 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 Dr. Lonsbary is considering doing a follow-up study in which instead of asking participants to listen to music to induce mood, she has them write either a story about a character who just won the lottery or a story about a character who just experienced the death of their spouse. This change in the mood variable is designed to enhance the study's _________ validity.
