工作记忆障碍的儿童在算术上有困难，以前进行了调查，使用可疑的选择技术和控制组，导致问题的结论赤字可能会发生。本研究试图克服这些批评，通过评估9岁的儿童与困难的具体算术，正常的阅读，并比较他们与年龄匹配和能力匹配的控制。一组10个任务被用来评估工作记忆的不同方面，包括执行功能的亚型。相对于年龄匹配的对照组，算术差的儿童有正常的语音工作记忆，但在空间工作记忆和执行处理的某些方面受损。与能力匹配的对照组相比，他们只在一项旨在评估长期记忆中持有和操纵信息的执行过程的任务中受损。工作记忆的执行和空间方面的这些缺陷似乎可能是算术成绩差的重要因素（C）1999年学术出版社。
Working memory impairments in children with difficulties in arithmetic have previously been investigated using questionable selection techniques and control groups, leading to problems concluding where deficits may occur. The present study attempted to overcome these criticisms by assessing 9-year-old children with difficulties specific to arithmetic, as indicated by normal reading, and comparing them with both age-matched and ability-matched controls. A battery of 10 tasks was used to assess different aspects of working memory, including subtypes of executive function. Relative to age-matched controls, children with poor arithmetic had normal phonological working memory but were impaired on spatial working memory and some aspects of executive processing. Compared to ability-matched controls, they were impaired only on one task designed to assess executive processes for holding and manipulating information in long-term memory. These deficits in executive and spatial aspects of working memory seem likely to be important factors in poor arithmetical attainment (C) 1999 Academic Press.
