Which of the following correlations would the psychologist hope to find in order to establish discriminant validity?

Asking an expert or experts to evaluate a measure is used to establish ________ validity.

Danesh has just read an article that describes a study that used a survey completed by participants to assess anxiety levels in adults. He is interested in the reliability of the survey and finds that the authors have provided information about both internal and test-retest reliability. However, there is no information about interrater reliability. Which of the following reasons explains why the authors do not report interrater reliability?

Dr. Leising conducts observational studies of adolescents interacting with peers during problem-solving tasks. She records each 30-minute interaction and then has the students in her laboratory code prosocial behaviors in the adolescents as they view each video. Because she has several students coding the videos, she calculates how reliable their scores are with each other by having them all code the same videos periodically. Which type of reliability is Dr. Leising calculating?

Dr. Smitherman conducted a study 5 years ago, and his graduate student now recommends that they conduct the study again to see if the effect still occurs.

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 suspects that the people who will most benefit from his study are high school and college students, who are asked to perform cognitive functions in various states of sleep deprivation. Given this information, what type of participants should Dr. Kushner recruit for his study?

Dr. Kushner is deciding whether he needs to give participants a reason for waking them up several times during the night. He knows that he cannot tell them the real reason, but he is unsure whether he should deceive them (give them a false reason why he is waking them up) or provide them with no cover story at all. Which of the following issues should be considered most heavily when deciding whether to use deception?

RESEARCH STUDY 5.1: 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.” Before using the measure in her study, Dr. Rodriquez gives the measure to a group of participants on the first day of the semester and again on the last day of the semester. Dr. Rodriquez is examining the scatterplot of the data she collected on the first day of the semester and the last day of the semester. On the scatterplot, she sees that the dots are very close to forming a diagonal line. This indicates which of the following?

She is concerned about the scale’s

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. If Dr. Sheffield’s measure does not actually measure pathological gambling, his measure is said to lack which of the following?

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.

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 gives his measure to his supervisor, who is also an expert in pathological gambling. His supervisor says that his measure appears to test all the components of pathological gambling, including feeling restless when attempting to stop gambling, jeopardizing jobs in order to keep gambling, and using gambling to escape from problems and a bad mood. Given this information, Dr. Sheffield’s measure has evidence of which of the following?

Dr. Sheffield gives his measure to a group of people that includes suspected problem gamblers and non-gamblers. Which of the following options below could he also do to get evidence for criterion validity?

He finds that people in the GA group have higher scores on his new measure than people in the AA group. Why did Dr. Sheffield do this?
