We examined age-related differences in strategy-choice behavior in 27 younger and 28 older adults. Participants solved 4 two-digit by two-digit multiplication problems. We expected them to initially calculate the answers but eventually switch to a retrieval strategy, recalling answers from memory. Three groups emerged: younger adults who met the criterion (20 consecutive, correct, retrieval trials selected and answered in time), older adults who met the criterion, and older adults who did not meet the criterion. Younger and older adults who met the criterion had similar performance patterns. Some older adults who did not meet the criterion were slower to learn, whereas others seemed to be averse to the retrieval strategy. Thus, older adult patterns in strategy choice are considerably more varied than younger adult patterns, suggesting different explanations for differences in memory performance.
