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 plans to tell his participants that the reason he is waking them up during the night is to recalibrate the EEG machine. This would be an example of which of the following?

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.

"Dr. White reads about a new theory that states that depression is caused by increased levels of estrogen in the womb. To test this theory, she conducted a study comparing the level of estrogen in amniotic fluid in individuals who were later diagnosed with depression with the level of those who did not develop depression. Dr. White found no differences between the groups in estrogen levels in the amniotic fluid. Based on these results, Dr. White should conclude that

1. 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 conditions, 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 people in Gamblers Anonymous (GA) and another group in Alcoholics Anonymous (AA). 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?
