阅读困难儿童工作记忆研究的新进展

Progress in Studies on Working Memory in Children with Reading Disabilities

工作记忆是一种对信息进行暂时加工和贮存的能量有限的记忆系统,在许多复杂的认知活动中起重要作用。研究表明,阅读困难与工作记忆缺陷密切相关,阅读困难儿童都存在语音回路功能缺陷以及中央执行器功能等方面的缺陷。今后研究将以整体的、发展的视角,不断改进研究方法,将行为研究和神经加工机制研究相结合,进一步探明阅读困难工作记忆缺陷的深层原因。

Studies on working memory in learning disabilities indicated that, children with reading disabilities suffer deficits related to the phonological loop (i.e., the inefficient accessing of phonological representation), and the central executive (i.e., capacity limitations in controlled attention processing). In other words, working memory deficits are fundamental problems of children and adults with learning disabilities. Combining with multi-approaches, future research seems to further explore why these working memory deficits result in learning disabilities.
