非语义性命名障碍：一个认知神经心理学的个案研究

本研究从认知神经心理学的角度，根据有关语言产生和词汇认知的理论，对一例脑损伤病人的命名障碍进行了较为细致的个案分析，研究表明：（１）命名障碍可分为语义性和非语义性两类；（２）病人ＬＹ的命名无能主要不是因为其语义系统受到损害，而是因为其语音提取受到损害，以致于恰当的语义激活不能激活恰当的语音表征；（３）ＬＹ在汉字阅读中的表现也表明了字形信息在词义激活中的重要性。

NON-SEMANTIC ANOMIA: A CASE STUDY OF A CHINESE PATIENT

A detailed case study was conducted of a braindameged patient (LY)who had severe deficits in theconfrontation naming of objects and Chinese charactersor words and in the phonological judgement of Chinesecharacters. HOwever, LY's performance in word repetition, picture-word matching,picture or word catego-rization, and semantic judgement was much less impaired. We concluded that LY was a non-semantic anomic patient whose semantic system was intact whilehis ability to retrieve phonology from semantic activation and from orthographic activation was damaged.The implications for theories of langUage productionand visual word recognition were discussed.
