摘要	汉语深层失读是目前阅读障碍中的一项重要研究课题。本研究围绕汉语深层失读进行了三方面的研究：第一，探查汉语深层失读的临床主要症状、伴随症状以及相互之间的关系，不同类型单字和词的阅读成绩；通过详细的实验，以拼音文字阅读的经典模型进行验证，发展并改进了汉语的阅读模型；第二，在研究汉语深层失读机制的基础上，进一步通过神经心理学测验分析汉语词汇－语义系统的组织规律和语义距离；第三，根据前两部分的研究结果制定康复策略，通过个案康复成果验证研究结论的可靠性。本研究采用了认知神经心理学的方法，主要对脑损伤的深层失读病人进行了研究，研究内容还涉及到正常人压力状态下的速读研究，并采取了计算机仿真技术对阅读模型进行了初步的模拟。对病人的研究既采用了统计分析技术考查整组病人的数据规律，也兼顾个案进行了分析。本论文首次系统地研究了汉语深层失读的临床表征；改进并提出了新的汉语阅读模型，创新地提出汉语阅读模型中的由语义亚词汇支路和语音亚词汇支路并行组成的亚词汇通路；发现了汉语深层失读不同于拼音文字深层失读的两大特点：没有显著的词类效应和想象度效应；发现汉语词汇－语义系统的组织与汉字的构字规则、想象度以及字的可拆分性相关；发现汉语深层失读病人的语音通达中，语义相关的诱发显著强于语音相关的诱发。
其他摘要	Chinese deep dyslexia is an important type of reading disorder that attracted many research interests. In the current thesis, three studies concerning Chinese deep dyslexia were performed: (1) clinical dominating and incidental symptoms were collected and their relationships were analyzed, and error scores of different character and word types compared; to verify typical reading model of alphabetic readers, and to develope a novel model for reading Chinese scripts; (2) based on these results, further neuropsychological analysis on the basic rules of lexical-semantic system and semantic distance were employed; (3) rehabilitation scheme were shaped to verify our research results. With cognitive neuropsychological methods, this study was mainly focused on deep dyslexic patients with brain impairment. The results were compared with those of normal people on rapid reading. Computer emulation was also used to describe reading process of patients. Both group analysis and case study were carried out. This study for the first time systematically investigated the clinical symptoms of Chinese deep dyslexia. A novel model was developed with a hypothesis that the sublexical pathway is composed of two parallel pathways: the phonetic sublexical pathway and the semantic sublexical pathway. Two characteristics of Chinese deep dyslexia were found compared with alphabetic deep dyslexia: (1) having no distinct word class effect and imagination effect; (2) the organization of Chinese lexical-semantic system has correlation with construct regulation, imagination and splitability of characters. Evoking of semantic correlation is stronger than phonetic correlation.
