Examining the effects of training on young and older adult implementation of spaced retrieval strategies

Abstract

ABSTRACT Although the benefits of spaced retrieval are well established, research suggests that young and older adults often fail to optimally implement this strategy. The present study examined how task experience with feedback influenced participant-implemented spaced retrieval and its effect on short and long-term memory retention. Young and older adults were instructed to either equally space or expand their retrieval of face-name associations throughout an ongoing reading task. Participants were then provided feedback on the accuracy with which they implemented experimenter instructions. Results showed that feedback improved utilization of retrieval practice in both young and older adults. Moreover, both age groups successfully produced a pattern of expanded retrieval when instructed to do so, but failed to properly implement equal spacing. Consistent with extant research utilizing experimenter-determined spaced retrieval schedules, our study showed that the inclusion of a longer spacing interval immediately following acquisition resulted in reduced forgetting across the retention interval.
