PSYCH 2300 CH 12 QUIZ QUESTIONS AND ANSWERS
WORKING MEMORY EXPERIMENT QUESTION 1
Normal rats are tested in a working memory task. In this task rats learn to hold a visual
stimulus (in working memory) over a delay period. Performance in the task is measured
as the percentage of correct choices at each delay length (5, 10, and 15 seconds). All
delay lengths are presented within the same single experimental session (120 trials)
with the order of delays randomized (example order: 15sec, 5, 5, 5, 10, 15, 10...etc.)
After animals learn how to perform the task the following experiment is conducted: All
animals underwent three sequential days of testing (separate experimental sessions) in
the task (day:1,2,3). Prior to each testing day all animals received one of the following
injections
A. Saline
B. PCP (induces deficit)
C. PCP + Galantamine (potential treatment)
Animals are randomly assigned to the following orders of injections: ACB, BAC, CBA.
The experiment prod - answer repeat measures and concurrent measures design
WORKING MEMORY EXPERIMENT QUESTION 2
T or F: The experiment uses a full counterbalance design for the order of injections. -
answer false
WORKING MEMORY EXPERIMENT QUESTION 3
How many interaction effects are possible for this experiment?
*You are not telling me whether or not there is an interaction effect, but rather how
many possible interactions must we investigate given the experimental design.
