Retrieval practice and elaborative encoding benefit memory in younger and older adults

Retrieval practice has been identified as a powerful tool for promoting retention. Few studies have examined whether retrieval practice enhances performance in older adults as it does in younger adults. Younger and older adults learned unrelated word pairs and were administered a test after a short (10 min) and long (2 day) delay. Encoding condition was manipulated between subjects, with participants studying the pairs twice, studying them once and taking an immediate test with feedback, or encoding them twice under different deep encoding conditions. In both age groups, equivalent benefits of testing relative to restudy were found. Deep processing also improved memory relative to restudy, suggesting that one factor that might benefit retention is varying the type of encoding task (either by testing or by providing a different instructional manipulation) to increase the accessibility of cues. Retrieval practice can support older adults' memory and is a viable target for training. (C) 2013 Society for Applied Research in Memory and Cognition. Published by Elsevier Inc. All rights reserved.
