摘要： 本研究通过两部分实验探讨汉语发展性阅读障碍儿童与正常儿童中央执行系统的容量差异和这种差异的性质。通过比较匹配生理年龄的不同阅读水平儿童在自定步速和固定步速的复杂阅读广度测验中的成绩，发现发展性阅读障碍儿童在两种阅读广度测验中都表现出中央执行系统容量的缺陷，这种缺陷既不能用加工效率理论，也不能用资源分配理论来解释，而符合一般容量假设。因此，本研究支持发展性阅读障碍儿童存在实时加工和存储信息的一般容量缺陷。

Abstract: Two experiments were conducted to explore the difference of the central executive capacity between dyslexic children and normal controls. The nature of this difference was also examined. The performance in self-paced and fixed-paced complex reading span test was compared between the participants with different reading ability but matched chorological age. The results suggest that dyslexic children were impaired in central executive ca?鄄pacity when performing both of the two kind tests, which was consistent with the general capacity hypothesis. Thus, the present study provides supports for the conclusion that dyslexic children were impaired in the central executive general capacity of on-line processing and information storage.

Key words: Chinese developmental dyslexia, central executive system, complex reading span test
