Roediger and Karpicke (2006) studied performance on a memory test in two groups of participants. In one group, participants studied the material twice (study-study). In the other group, participants studied the material once and then were tested on the material (study-test). A final test measuring recall was administered in both groups after various retention intervals. Which statement about performance on the final test is true?

Question

Quizplus · Accepted Answer

Roediger and Karpicke found that recall was better in the study-test group at long retention intervals (i.e. one week). This is because the act of retrieving information from memory during the test phase helps to strengthen and consolidate the memory trace, leading to better long-term retention. However, at short retention intervals (i.e. 5 minutes), recall was better in the study-study group, as repeated exposure to the material helped to strengthen the memory trace during the study phase.
