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. To test his measure, Dr. Sheffield gives his measure to a group of his clients and at the same time measures how many times they have been gambling in the past month. He predicts that clients who score higher on his measure will also report gambling more times in the past month. This procedure is meant to provide evidence for which of the following? a. criterion validity b. content validity c. discriminant validity d. face validity
a. criterion validity

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. The institutional review board (IRB) that reviews his committee must have which of the following as a member? a. the prison warden b. a prisoner c. a prisoner advocate d. a criminal justice professor
