We investigated six patients with progressive focal dementia or progressive aphasia, who showed impairments in knowledge of word meaning ranging from moderate to very severe. In all cases, a test of oral word reading demonstrated preserved reading of words with regular spelling-to-sound correspondences (e.g. MINT), but impaired reading of words with atypical correspondences (e.g. PINT). The level of success on these "exception" words was significantly related to word frequency, and the most common error was the assignment of a more typical spelling-sound correspondence. Various explanations are considered for this common association between loss of word meaning and a surface alexic pattern of reading performance.
我们研究了6例进行性局灶性痴呆或进行性失语患者，他们在词义知识方面存在中度至非常严重的损害。在所有病例中，一项口头单词阅读测试表明，具有规则拼写-发音对应关系的单词（如MINT）阅读能力保留，但具有非典型对应关系的单词（如PINT）阅读能力受损。这些“特殊”单词的成功水平与单词频率显著相关，最常见的错误是赋予更典型的拼写-发音对应关系。针对词义丧失与阅读表现的表层失读模式之间的这种常见关联，我们考虑了各种解释。
