An analytical investigation of the residual reading capacities of a single patient with dyslexia without dysgraphia is reported. Both his ability to name and to comprehend letters and words were severely impaired. The major finding of this investigation was AR's striking capacity for categorizing words he could not read. In addition there was evidence of semantic priming effects. Thus AR was frequently able to achieve partial comprehension of words he could not read. The orthodox interpretation of the dyslexia without dysgraphia in terms of a disconnection syndrome is shown to be inappropriate, at least for the present case, where the deficit appears to be within the semantic domain; it is argued that this type of dyslexia is due to an impairment in accessing semantic information.
本文报告了对一名患有单纯性阅读障碍（无书写障碍）患者残余阅读能力的分析研究。他对字母和单词的命名及理解能力均严重受损。该研究的主要发现是，AR对他无法读出的单词进行分类的能力惊人。此外，有证据表明存在语义启动效应。因此，AR常常能够对他无法读出的单词实现部分理解。结果表明，至少就目前这个缺陷似乎存在于语义领域的病例而言，用脱节综合征来正统解释单纯性阅读障碍是不合适的；有人认为，这种类型的阅读障碍是由于获取语义信息的能力受损所致。
