ABSTRACT We report on an English-speaking, aphasic individual (RB) with a spelling deficit more severely affecting orthographically irregular words for which phonologically plausible errors (PPEs) were produced. PPEs were observed for all word forms, with the exception of inflectional suffixes, despite the irregular sound-print mappings of many inflectional suffixes (e.g., walked → /wɔkt/). RB's pattern replicates that reported in Badecker, Rapp, and Caramazza (Badecker, W., Rapp, B., & Caramazza, A. (1996). Lexical Morphology and the Two Orthographic Routes. Cognitive Neuropsychology, 13, 161–176). We extended their investigation by examining RB's spelling of derived words and found a selective deficit for derived words compared to inflected words in writing. This selective deficit did not appear to reflect differences in morphological transparency or suffix frequencies that exist between inflection and derivation. This is the first evidence that distinct neural mechanisms support inflection and derivation in spelling.

书面语中屈折词和派生词的处理

摘要我们报告了一个说英语的失语症个体 (RB)，他的拼写缺陷更严重地影响了拼写不规则的单词，因此产生了语音上似是而非的错误 (PPE)。尽管许多屈折后缀（例如，walked → /wɔkt/）的音印映射不规则，但所有词形都观察到了PPE，但屈折后缀除外。RB 的模式复制了 Badecker、Rapp 和 Caramazza（Badecker, W.、Rapp, B. 和 Caramazza, A.（1996）。词汇形态学和两条正字法路线。认知神经心理学，13、161-176）。我们通过检查 RB 对派生词的拼写扩展了他们的调查，并发现与写作中的屈折词相比，派生词的选择性缺陷。这种选择性缺陷似乎没有反映在变形和派生之间存在的形态透明度或后缀频率的差异。这是第一个证据表明不同的神经机制支持拼写的屈折和派生。
