2. Choosing DV and IV – Write Ups

A. Scenario #1 Dr. Imanut wants to examine whether a new drug increases the maze running performance of older rats. Just like aging humans, older rats show signs of poorer memory for new things. Dr. Imanut teaches two groups of older rats to find a piece of tasty rat chow in the maze. One group of rats is given the new drug while they are learning the maze. The second group is not given the drug. One week after having learned the maze he retests the rats and records how long it takes them to find the rat chow.

B. Scenario #2 A researcher wanted to study the effects of sleep deprivation on physical coordination. The researcher selected 25 year-old male college students and deprived some of the subjects to either 24, 36, or 45 hours of sleep.

C. Scenario #3 An investigator had 60 subjects watch a videotaped re-enactment of a bank robbery. Half of the subjects were asked by a police investigator to recall the event, while the remaining subjects were interviewed by a police investigator while they were hypnotized.

C. Scenario #3 A researcher wanted to know whether the number of people present would influence subjects' judgments on a simple perceptual task. In each case the other members of the group gave an incorrect answer. The researcher then noted whether the subject conformed to the group decision.
