Exercise 2. In a study of memory processes animals were presented with a one-trial avoidance task. As soon as they stepped across a line down the center of their cage they were shocked. Three groups of animals differed in the area in which they had electrode implants in their brains(neutral site, Area A, or Area B). Each group was further divided and given electrical stimulation either 50, 100, or 150 msec. after crossing the line and receiving foot shock. If the brain area is involved in memory, stimulation would be expected to interfere with consolidation and retard learning of the avoidance response. The dependent variable was the number of seconds it took the animal to cross the line on the second trial.

Transcribed Image Text:Exercise 2. In a study of memory processes animals were presented with a one-trial
avoidance task. As soon as they stepped across a line down the center of their cage
they were shocked. Three groups of animals differed in the area in which they had
electrode implants in their brains(neutral site, Area A, or Area B). Each group was
further divided and given electrical stimulation either 50, 100, or 150 msec. after
crossing the line and receiving foot shock. If the brain area is involved in memory,
stimulation would be expected to interfere with consolidation and retard learning of the
avoidance response. The dependent variable was the number of seconds it took the
animal to cross the line on the second trial.
