Age differences in prefontal cortical activity in working memory

Article Abstract:

Research examines the relationship between working memory and aging in a sample consisting of six younger and six older adults. Results show greater dorsal prefrontal cortex activation in younger adults and greater rostral prefrontal cortex activation in older adults. Furthermore, aging seem to affect dorsal prefrontal cortex brain regions connected to working memory.

Accounting for age differences on the Wisconsin Card sorting Test: decreased working memory, not inflexibility

Article Abstract:

This article evaluates the relationship between cognitive inflexibility/reduced working memory and aging using the Wisconsin Card Sorting Test. Data indicate that performance of older adults is influenced by the amount of information they can store or process using working memory.

A longitudinal study of implicit and explicit memory in old persons

Article Abstract:

An examination on the explicit memory and priming with reference to multiple tests over four annual data-collection waves in a large group of older persons without dementia at baseline was done. The findings indicate that explicit memory and priming are dissociable based on age-related change and that mildly reduced priming is not an inevitable consequence of growing older.
