LABOR AND GAIN, BUT THEN LABOR IN VAIN: DIMINISHING RETURNS OF REPEATED RETRIEVAL PRACTICE
| Title: | LABOR AND GAIN, BUT THEN LABOR IN VAIN: DIMINISHING RETURNS OF REPEATED RETRIEVAL PRACTICE |
| Author: | Pyc, Mary A. |
| Description: | In two experiments, I investigated the relationship between the number of correct recalls during retrieval practice and subsequent memory for those items. Results showed both a labor and gain effect and a labor in vain effect: Final test performance was enhanced by correctly recalling items more than once during practice. However, there were also diminishing returns to final test performance as the number of times an item was correctly recalled during practice increased. Thus, correctly recalling items more times during practice did not always lead to higher levels of final test performance. Additionally, the rate of approach to asymptotic final test performance with increasing correct recalls during practice depended on the retention interval but not on the interstimulus interval used during practice. Discussion focuses on implications of these results for theories of testing effects. |
