Age Differences in Implicit and Explicit Associative Memory: Exploring Elaborative Processing Effects

Abstract

Research in memory processes suggests implicit memory is more resistant to the effects of aging than explicit memory. Two experiments examined how variations in level of processing affect memory for novel word-pair associations across age groups. The results indicate that new learning may rely on some degree of elàborate and even explicit processing and that older adults show deficits in any form of new learning. Explicit associative memory benefited from elaborative processing for both age groups and age differences appeared to relate to overall working-memory capacity rather than effective use of elaborative processes. These results support a model of associative memory that distinguishes automatic unconscious processes versus conscious controlled processes in which older adults exhibit deficits in associative memory tasks that actually rely on consciously controlled processes.
