The Time Course of Lexical Activation in Fluent and Nonfluent Aphasia

  • Chapter
Linguistics and Cognitive Neuroscience

Part of the book series: Linguistische Berichte ((LINGB))

Abstract

There is a remarkably consistent distinction between fluent and nonfluent aphasics in their performance on measures of semantic comprehension vs. lexical activation. Nonfluent aphasics perform “normally” — that is, similar to age-matched control subjects — on off-line semantic judgment tasks, e.g. grouping words based on semantic relatedness and matching pictures of individual objects to their category names (e.g. Goodglass & Baker 1976; Whitehouse, Caramazza & Zurif 1978; Zurif, Caramazza, Myerson & Galvin 1974). They do not perform normally, however, on measures of lexical priming that require rapid but ostensibly easier lexical (“word-non word”) judgments. In direct contrast to nonfluent aphasics, fluent aphasics have significant difficulty making semantic judgments, but perform normally on measures of lexical priming.
