Abstract

Abstract: 【Objective】 To explore the switch function in Chinese developmental dyslexic children. 【Methods】 Dyslexic children were chosen according to the International Classification of Diseases-10(ICD-10), and control group was matched for gender, age. All subjects took the Number Switch Task and their reaction time, error rate were analyzed. 【Results】 The error rate of dyslexic children was significantly higher on the switch trials(P<0.01)and marginal significantly higher on the non-switch trials(P=0.07)compared to the normal readers. And no significant difference both in the switch cost and the RTs between dyslexic and normal readers(P>0.01). 【Conclusions】 Chinese dyslexic children have a deficiency in the switch processing.

Key words: Chinese dyslexic children, switch function, working memory, number switch task

摘要： 【目的】探明汉语阅读障碍儿童在工作记忆转换功能上的特征。【方法】按照ICD-10 中阅读困难的诊断标准,从武汉某小学筛选出16名汉语阅读障碍儿童为实验组,并从同性别、同年级的正常儿童中选择正常对照16人。研究采用数字转换任务的研究范式,测量了两组儿童在转换任务上的反应时、错误率。【结果】阅读障碍组与正常对照组在转换任务的错误率上差异具有统计学意义(P<0.01),在无转换任务上的错误率差异具有边缘显著(P=0.07),而转移消耗、反应时等差异无统计学意义(P>0.01)。【结论】阅读障碍儿童的转换能力具有一定缺陷。
