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.
本文回顾了近期对早期阿尔茨海默病型痴呆（AD）患者初级记忆功能的神经心理学研究，特别提及了近期关于工作记忆的研究。初级记忆缺陷呈现出一种相当独特的模式，在自由回忆中近期效应相对未受损害，记忆广度有中度损害，而在分心后的短期保持方面有更严重的损害。这些缺陷的本质与工作记忆模型（Baddeley & Hitch，1974）相关进行了探讨。研究表明，言语环路系统功能正常，但工作记忆的控制过程存在损害。
