| 摘要
目的：明确视觉性失语症伴纯失读患者的语言加工损害水平。
方法：对1例视觉性失语症患者采用汉语失语症心理语言评价及其他相关检查进行语言评价。
结果：①患者的基本视知觉、不同视点物体匹配的结构表征检查正常；②从视觉输入通达到详尽的语义受损，表现为视觉图命名障碍和视觉图—图联系困难；③将视觉词形转换为对应的语音表征受损，表现为视觉输入词朗读障碍；④将视觉词形映射到语义较听觉语音映射到语义受损更为显著，即字形输入词典到语义系统的联系受损更为严重，表现为视觉词—图匹配较听觉词—图匹配显著受损。
结论：该例视觉性失语症患者的语言加工损害主要为从视觉输入（事物）通达到详尽的语义受损，以及将视觉字形通达到语义和语音表征受损。 |

| Abstract
Objective: To identify which level of language processing is impaired in an optic aphasic patient with pure alexia.
Method: Psycholinguistic assessment in Chinese aphasia (PACA) and other related tests were used to assess an optic aphasia with pare alexia patient's language impairment.
Result: ①The patient's basic visual perception and structure representation by object-picture matching with different view points was normal. ②Accessing to semantic system from visual imports was impaired, showing difficulty in visual picture naming and visual picture-picture correlation tasks. ③Conversion from visual word form into its phonologic representation was impaired, showing difficulty in word loud reading. ④Mapping from visual word form to semantic system was more disrupted than that from sounds to semantic system, indicating visual word-picture matching was more difficult than auditory word-picture matching.
Conclusion: The main language processing impairment in this optic aphasic patient was failure to access from visual import information (object) to detailed semantics and from visual word form to semantic and to phonological representation. |
