Abstract

【Objective】 To explore visual-spatial sketch Pad function in Chinese developmental dyslexic children. To study the correlation between visual-spatial working memory of subjects and language cognition. 【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 were assessed by written vocabulary skills, phonological processing skills and orthographic skills. Visual matrix span task and Corsi span task were used to measure visual-spatial working memory. 【Results】 The scores of dyslexic children on language cognition were significantly lower on the normal readers(P<0.05). The scores of dyslexic children on Visual matrix span task scores and Corsi span task were significantly lower on the normal readers(P<0.05). There were significant statistically correlation coefficients between the scores of Visual matrix span task scores and Corsi span task and the scores of written vocabulary skills and orthographic skills. There were no significant statistically correlation coefficients with phonological processing skills(P＞0. 05). 【Conclusions】 Children with developmental dyslexia show deficits in visual-spatial working memory ability. There are significant correlations between visual-spatial working memory and their written vocabulary skills and orthographic skills.
