摘要：The typical time-course of activation of a lexical item during an ongoing auditory sentence is not observed in studies exploring on-line language processing with individuals who have agrammatic aphasia. That is, they demonstrate a pattern of delayed initial lexical access as well as slowed re-access (Love et al., 2008). This latter finding suggests that the 'syntactic9 comprehension disorder observed in agrammatic aphasia might have its roots in a lexical access deficit; a slowed lexical activation system may result in lexical information "feeding^ syntactic processing too slowly, leading to subsequent syntactic deficits. The bulk of this evidence, however, has come from investigations of complex filler-gap constructions. To address this issue，we present a cross-modal picture priming (CMPP) study using simple active sentence constructions to map out the time course of lexical activation throughout a sentence in both college-age unimpaired listeners and language impaired individuals with agrammatic aphasia.
