ABSTRACT We describe the performance of an aphasic individual, K.A., who showed a selective impairment affecting his ability to perceive spoken language, while largely sparing his ability to perceive written language and to produce spoken language. His spoken perception impairment left him unable to distinguish words or nonwords that differed on a single phoneme and he was no better than chance at auditory lexical decision or single spoken word and single picture matching with phonological foils. Strikingly, despite this profound impairment, K.A. showed a selective sparing in his ability to perceive number words, which he was able to repeat and comprehend largely without error. This case adds to a growing literature demonstrating modality-specific dissociations between number word and non-number word processing. Because of the locus of K.A.’s speech perception deficit for non-number words, we argue that this distinction between number word and non-number word processing arises at a sublexical level of representations in speech perception, in a parallel fashion to what has previously been argued for in the organization of the sublexical level of representation for speech production.

保留数词知觉的词聋

摘要 我们描述了失语症个体 KA 的表现，他表现出选择性障碍，影响了他感知口语的能力，同时在很大程度上保留了他感知书面语言和产生口语的能力。他的口语感知障碍使他无法区分在单个音素上不同的单词或非单词，并且他在听觉词汇决定或单个口语单词和单个图片与语音箔匹配方面的机会并不比机会好。引人注目的是，尽管有这种严重的损伤，KA 在感知数字单词的能力方面表现出选择性的节制，他能够在很大程度上没有错误地重复和理解这些单词。这个案例增加了越来越多的文献，展示了数字词和非数字词处理之间特定于模态的分离。由于 KA 的位置
