摘要目的：考察汉语发展性阅读障碍是否存在视觉字形加工缺陷，探究视觉加工缺陷与阅读能力之间的关系。方法：采用识字量筛查、瑞文测验等筛选出14名三年级阅读障碍儿童（DD组），14名年龄匹配的三年级正常儿童（CA组）以及14名与阅读障碍儿童识字量匹配的一年级儿童（RL组）。采用计算机测验的形式，让三组被试进行视觉形状匹配实验（包括视觉字形匹配实验和笔画组合匹配实验），分别比较三组被试在两个实验中的的正确率。结果：笔画组合匹配任务的结果表明，组间差异主效应不显著（F=1。289，p=0。287），表明三组儿童之间没有差异。视觉字形匹配任务的结果表明组间存在差异（F=3。032，p=0。06）。进一步分析表明，DD组与CA组的视觉字形匹配任务正确率之间差异显著（p=0。021），而DD组与RL组的视觉字形匹配任务正确率之间差异不显著（p=0。111），CA组与RL组的视觉字形匹配任务正确率之间差异也不显著（p=0。425）。结论：汉语发展性阅读障碍者在对文字的视觉字形加工方面存在缺陷，而对无意义笔画组合的视觉加工方面不存在缺陷。89311

Objective: To investigate the relationship between visual word form processing deficit and reading ability in Chinese developmental dyslexia。 Methods: Use the literacy amount of screening test, the Raven's Standard Progressive Matrices to selected 14 dyslexic children (DD group) from the third grade, 14 age-matched normal children in the third grade (CA group) and 14 reading-matched children from the first grade children (RL group)。Children in the three groups were tested in a visual matching task in which visual words and stroke combinations were used。The accuracy in the three groups was analyzed 。 Results: In the stroke combination condition ,the results showed that there was no significant difference across the three groups (F=1。289, p=0。287)。 However, in the visual word condition, the main effect of group was marginally significant（F=3。032，p=0。06）。Results in the further analysis showed that the accuracy in the DD group was significantly lower than that in the CA group (p=0。021), while no group difference was found between the DD and and RL groups (p=0。111),or between the CA group and the RL group (p=0。425)。 Conclusion: There was a specific impairment in visual word form processing in Chinese dyslexic chidren。
