摘要: 以速示的方法,在单侧视野呈现单字词和双侧视野同时呈现单字词的条件下,比较了有听力的被试和聋人被试在汉字识别时大脑两半球机能的非对称性。结果表明,有听力的被试表现为右侧视野(左侧大脑半球)的优势效应、而聋人被试则表现出相反方向的大脑半球的优势功能。但聋人被试左侧大脑半球的功能明显降低,而右侧大脑半球的功能与有听力的被试相比几乎是同等的。表明言语知觉的缺失严重地阻碍了以语音为中介的左侧大脑半球功能的正常发展。

Abstract: The asymmetry of hemisphric function in recognizing Chinese single words by normal hearing Ss and prelingually deaf Ss were compared by using tachistoscopic method. The results indicated that the two groups had opposite hemispheric advantage both when the test words were presen- ted unilaterally and when they were presented simultaneously to the right and left visual field, i.e., the deaf Ss showed the left visual field advan- tage (the right hemisphere) and the normals showed that of the right visual field (the left hemisphere). However, the functions of the left hemisphere in the deaf declined while their right hemisphere functioned as well as the normals', which suggested that the absence of the speech perception imp- eded severely the normal development of the left hemisphere function me- diated by phonological and phonetic information processing. In recognition processing of Chinese characters, the speech sound was probably an im- portant factor to determine cerebral lateralization. There was no difference between the right and left visual fields in the recognition of Arabic num- erals for both groups.
