  • Title: Further considerations regarding inhibitory processes, working memory, and cognitive aging.
    Author: Grant JD, Dagenbach D.
    Journal: Am J Psychol; 2000; 113(1):69-94. PubMed ID: 10742844.
    Abstract:
    The present study explored the relationship between inhibitory processing (as indexed by identity negative priming in a letter-naming task), working memory, discourse processing, and cognitive aging effects. Consistent with several other recent reports, this study found evidence of intact inhibitory processing, as measured by negative priming, in older adults as well as younger adults. This intact negative priming occurred in conjunction with diminished working memory span and impaired memory in the discourse processing task in the same sample of older adults, further arguing against the likelihood that declines in these areas are caused by impairments in the inhibitory processes measured by negative priming. The implications of these results for theories of cognitive aging and possible reasons for inconsistent findings regarding negative priming effects among the elderly are discussed.
