Abstract

We present a cross-modal priming study using simple active sentence constructions to map out the time-course of lexical activation throughout a sentence. Preliminary findings suggest that in contrast to our unimpaired listeners who demonstrated immediate initial activation of a lexical item and a linear, relatively gradual decay, our participants with agrammatic aphasia demonstrated a pattern of late initial activation, and then immediate decay.  We surmise that this delayed lexical access coupled with the accelerated time-course of decay contributes to what appears to be a disrupted integration process.
