Abstract

The cardinal deficit of people with aphasia (PWA) is anomia (Goodglass & Wingfield, 1997). This deficit is believed to be indicative of disruption of two cognitive processes: (i) accessing a semantic description of the target concept, and/or (ii) retrieval of a fully phonologically specified representation (e.g., Dell, 1986). During discourse, in addition to these core processes that serve word retrieval, production also depends on “…factors external to the lexicon…” (p. 169, Wilshire & McCarthy, 2002). The latter processes might influence the selection of lexical items based on syntactic, structural, and/or pragmatic criteria that can be either automatic or meta-cognitive.
