We report the naming performance of a patient (DM) with a fluent progressive aphasia who made phonological errors in all language production tasks. The pattern of errors in naming was strikingly clear: DM made very many phonological errors that resulted almost always in nonword responses. The complete absence of semantic errors and the very low ratio of formal errors relative to nonword errors (1.6:30.3) in DM's performance are discussed in the context of recent claims about the nature of naming deficits in fluent aphasics. We argue that DM's performance makes highly improbable the claim that fluent aphasia results from global lesions affecting all levels of the lexical access system equally.
我们报告了一位患有流畅性进行性失语症患者（DM）的命名表现，该患者在所有语言生成任务中都出现了语音错误。命名中的错误模式非常明显：DM犯了非常多的语音错误，几乎总是导致非词反应。在最近关于流畅性失语症患者命名缺陷本质的观点背景下，讨论了DM表现中完全没有语义错误以及形式错误与非词错误的比例非常低（1.6:30.3）的情况。我们认为，DM的表现使得那种认为流畅性失语症是由同等影响词汇通达系统所有层面的全局性损伤所致的观点极不可能成立。
