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
