摘　　要：为探讨汉语发展性阅读障碍低年龄段小学生的视觉注意广度,以7—9岁低年龄段小学生为对象,选取发展性阅读障碍和正常阅读能力小学生各28名,采用2(被试群体:发展性阅读障碍组小学生、正常阅读能力组小学生)×2(汉字类型:简单、复杂)的两因素混合设计,使用Visual-1-back任务测量视觉注意广度,记录正确率、正确反应的反应时,并计算辨别力指数d’值。结果显示,发展性阅读障碍组正确率和辨别力指数小于正常阅读能力组,发展性阅读障碍组正确反应的反应时大于正常阅读能力组;简单汉字的正确率和辨别力指数大于复杂汉字,简单汉字的反应时小于复杂汉字。汉语发展性阅读障碍低年龄段小学生对汉字材料表现出视觉注意广度缺陷,进一步支持视觉到语音的映射这一观点。In order to investigate the visual attention span(VAS)deficit of primary school students with Chinese developmental dyslexia(DD)in the low age group,28 primary school students with developmental dyslexia(DD)and 28 typically developing(TD)students were selected from the low age group of 7-9 years oldas subjects.This study adopted 2(subjects groups:primary school students with DD、primary school students with TD)×2(Chinese character types:simple、complex)two-factor hybrid design,using visual-1-back task to measure visual attention span,record accuracy,reaction time of correct response,and calculate the discrimination index d’value.The results show that the accuracy and discernment index of the DD group are lower than that of the TD group,and the reaction time of the DD group is higher than that of the TD group.Besides,the accuracy and discrimination index of simple Chinese characters are higher than that of complex Chinese characters,and the response time of simple Chinese characters is lower than that of complex Chinese characters.Primary school students with low age and DD show visual attention span deficit in Chinese characters,which further supports the view of visual-to-speech mapping.
