Abstract

Semantic comprehension training paired with verbal production leads to improved word retrieval in individuals with aphasia. In a single-participant design, we investigated effects of semantic+phonologic training provided via computer with Moss Talk multi-mode matching exercises. Five individuals with moderate to severe word retrieval impairments participated; two also had significant impairments of lexical comprehension. Those two participants demonstrated increases in comprehension for trained and untrained words. All five participants improved in picture naming, particularly for trained words. We argue that lexical-semantic changes mediated training effects in both tasks along with alterations in attentional capabilities that influenced word comprehension more generally.
