Abstract

The article focuses on age-related differences in cognitive mechanisms, specifically examining the role of processing speed (PS) in the relationship between working memory (WM) and prospective memory (PM). The study involved healthy older adults (ages 60–89) and young adults (ages 18–29) who completed cognitive tasks including the WAIS-IV Digit Span, WAIS-IV Coding, and the Virtual Kitchen Protocol for PM. Results indicated that in older adults, PS significantly mediated the positive influence of WM on PM, a pattern not observed in young adults. This suggests that older adults may rely on processing speed as a compensatory mechanism to support prospective memory, highlighting potential age-related changes in neurocognitive resource allocation.
