title: Primary and working memory functioning in Alzheimer-type dementia.
abstract: This paper reviews recent neuropsychological studies of primary-memory functioning in early Alzheimer-type dementia (AD) with specific reference to recent research on working memory. The deficits in primary memory follow a fairly distinct pattern with a comparatively unimpaired recency effect in free recall, a moderate impairment in memory span, and a more substantial impairment in short-term retention following distraction. The nature of these deficits is considered in relation to the Working Memory Model (Baddeley & Hitch, 1974). It is suggested that the Articulatory Loop System is functioning normally but that there is an impairment in the control processes of working memory.
