Adult age differences in short-term memory: the role of inhibitory processes [abstract]

By Elizabeth A. Maylor

Abstract

Detailed analysis of errors in the serial recall of lists of items reveals that older adults make significantly more movement, omission, and intrusion errors than younger adults. The increase in intrusion errors is consistent with Hasher and Zacks' (1988) proposal of an age-related decline in the use of inhibitory mechanisms to prevent irrelevant information from entering working memory. However, data from older and younger adults in a "Ranschburg" experiment in which the recall of lists with repeated items is compared with the recall of lists with no repetitions are inconsistent with a second aspect of Hasher and Zacks' hypothesis, namely, that there is age-related decline in the use of inhibitory mechanisms to prevent information from remaining in working memory when no longer relevant
