4～6年级小学生发展性阅读障碍的异质性研究

The Heterogeneity of Chinese Developmental Dyslexia

通过比较阅读障碍儿童和正常儿童在语音意识、语素意识、语音通达(语音判断)和语义通达(语义相关判断)等任务中的表现,考察阅读障碍内部的异质性以及汉语阅读障碍儿童缺陷的主要类型。结果表明,影响儿童阅读的因素包括语音、语素和词典通达等。阅读障碍儿童内部存在一定的异质性。而从汉语的本身特点和语素与各测验之间的关系来看,汉语的语素缺陷可能成为阅读困难的重要原因之一。

By comparing the performances on phonological awareness test , morphological awareness test and on-line lexical access tests , the present study examined the heterogeneity and the dominant deficit of Chinese developmental dyslexia .The results showed that many factors, including phonological awareness , morphological awareness and the speed of lexical access , play an important role on Chinese reading. Chinese dyslexia are not homogeneous and morphological deficit may be an important reason for Chinese developmental dyslexia.
