Abstract

Adults with aphasia, right hemisphere brain damage or no brain damage completed a
semantic judgment task alone and in competition with a lexical decision task. The study’s
purpose was to specify further resource models of aphasia by examining whether
attentional factors interact with stimulus parameters (i.e., semantic relatedness) known to
influence semantic processing, and whether execution of the semantic task in isolation
(i.e., material-specific resource limitations), attention test scores (i.e., general attentional
abilities), or both are important predictors of dual-task outcomes. Findings relate to the
nature of attention deficits in aphasia, and interactions between attention and language in
normal and patient populations.
