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.
