Question
The following table reflects the results of a study by Roediger and Karpicke (2006). The authors investigated whether the test-enhanced learning effect (the demonstration that repeated testing improves memory for material) was due merely to repeated exposure to the material. They randomly assigned participants to one of two study conditions (study-study or study-test) and to one of three retention interval conditions (final test at a delay of five minutes, two days, or one week). The dependent variable was the proportion of idea units recalled from an encyclopedia passage.
Table: Test-Enhanced Learning
(Table: Test-Enhanced Learning) The cells of this study reflect an interaction. Which statement best describes the interaction?
a. On average, memory performance decreased as the retention interval decreased.
b. People in the study-test condition performed more poorly on the five-minute recall test than did those in the study-study condition, but at longer retention intervals (two days and one week); those in the study-test condition performed better than those in the study-study condition.
c. On average, memory performance increased as the retention interval increased.
d. On average, people in the study-test condition had better memory than did the people in the study-study condition.
