Abstract

The concept of working memory involves a short duration system in which small amounts of information are simultaneously stored and manipulated in the service of accomplishing a task (Caplan & Waters, 1999). Individuals with aphasia have working memory impairments to the extent they suffer from executive functioning limitations and deficits specific to language areas including syntax, phonology, and semantics (Laures, Odell, & Coe,2003; Wright & Shisler, 2005). In particular, deficits in working memory could contribute to a breakdown in word retrieval which can restrict the participation of an individual with aphasia in the most meaningful communication activities, particularly conversation (Goodglass & Wingfield, 1997). There is evidence that a Semantic Feature Analysis (SFA) improved word retrieval and even conversation in individuals with aphasia by providing semantic cueing for access to the semantic and phonological networks (Massaro & Tompkins, 1992; Rider, Wright, Marshall, & Page, 2008; Peach & Reuter, 2009).
