Accounts of spoken word production differ on whether aphasics' formal paraphasias derive solely from segmental distortion or whether some derive instead from whole word substitution. Form-related paraphasias produced by nine aphasics during picture naming were examined for evidence of lexical effects (word, frequency, and grammatical class biases) and for the manner in which target phonemes and word shape were preserved. Preservation patterns were consistent with previous descriptions of aphasic and nonaphasic form-related speech errors. Evidence for word and frequency biases was found, as well as a grammatical class bias sensitive to the degree of target-response segmental overlap. In conjunction, the results indicate that formal paraphasias arise, at least in part, via word substitution. The findings are supportive of interactive models with phonological-to-lemma feedback and/or modular models with a grammatically organized lexeme level.
关于失语症患者的形式性错语是完全源于音段扭曲，还是部分源于整词替换，言语产生的相关描述存在差异。研究了9名失语症患者在图片命名过程中产生的与形式相关的错语，以寻找词汇效应（单词、频率和语法类别偏差）的证据，以及目标音素和单词形状的保留方式。保留模式与之前对失语症和非失语症患者与形式相关的言语错误的描述一致。发现了单词和频率偏差的证据，以及对目标-反应音段重叠程度敏感的语法类别偏差。综合来看，结果表明形式性错语至少部分是通过单词替换产生的。这些发现支持了具有语音到词元反馈的交互模型和/或具有语法组织词元水平的模块模型。
