| 摘 要： | 本研究以38名不同亚类型的数字加工和计算障碍学生为实验组,以38名阅读能力以及数字加工和计算能力都处于中等水平的同年龄学生为年龄匹配组,以38名数字加工和计算能力与实验组相当且阅读能力中等的学生为能力匹配组,对数字加工和计算障碍的不同亚类型与工作记忆三个子系统的关系进行了探讨,结果表明,数字加工和计算障碍的不同亚类型在工作记忆的缺陷模式上存在差异:尽管所有亚类型的工作记忆执行系统功能均不如能力匹配组和年级匹配组,即不同亚类型的数字加工和计算障碍学生在工作记忆的中央执行系统上均存在缺陷,但是,他们在语音回路和视觉空间板上的缺陷模式却有所不同.

| Abstract: | This study aims to explore the relationship between the subtypes of number processing and dyscalculia and the three subsystems of working memory,by conducting a survey of 38 students with number processing and calculation disorders,38 students with a medium level of reading ability,number processing and calculation,and 38 students both with number processing and calculation disorders, and with a medium level of reading ability.The results show the following: the different subtypes of number processing and calculation disorders show difference in the defective patterns of working memory;although the students with number processing and calculation disorders in different subtypes have defects in the central executive system of working memory,they have different defective patterns in the phonological loop and the visual-spatial sketchpad. |
