ABSTRACT

Dyslexic children have impairments in working memory and manual dexterity. Studies have shown that when cognitive development has deficits, motor development is often impaired, indicating a strong interconnection between both domains, and the possibility of interference with each other’s proper functioning. Thus, a new literature review is necessary to understand which components of working memory and manual dexterity are affected in dyslexic children and the possible relationship between them. This review aimed to perform a systematic review and meta-analysis to analyze both skills in dyslexic children. The protocol was carried out according to the criteria established by PRISMA being registered at PROSPERO under number CRD 42021238901. Six literature databases were searched to locate studies published between 2001 and 2021: EMBASE, ERIC, ISI Web of Science, PubMed, PsycINFO, and Scopus. 21 studies met the inclusion criteria. The findings suggest that dyslexic children have significantly poorer visuospatial and verbal working memory with more impairments in the phonological loop. No significant differences were found in manual dexterity.

摘要

诵读困难的儿童在工作记忆和手部灵活性方面存在障碍。研究表明，当认知发展出现缺陷时，运动发育往往会受损，这表明这两个领域之间存在很强的相互联系，并且可能会干扰彼此的正常功能。因此，有必要进行新的文献综述，以了解阅读障碍儿童的工作记忆和手部灵巧性的哪些组成部分受到影响，以及它们之间可能存在的关系。本综述旨在进行系统回顾和荟萃分析，以分析阅读障碍儿童的这两种技能。该协议是根据 PRISMA 制定的标准执行的，该标准在 PROSPERO 注册，编号为 CRD 42021238901。搜索了六个文献数据库以查找 2001 年至 2021 年间发表的研究：EMBASE、ERIC、ISI Web of Science、PubMed、PsycINFO 和 Scopus。21 项研究符合纳入标准。研究结果表明，阅读障碍儿童的视觉空间和语言工作记忆明显较差，语音回路受损更多。在手的灵巧度方面没有发现显着差异。
