The Lexical Bias Hypothesis suggests that people with aphasia (PWA) will have difficulty comprehendingsentences in which verbs do not occur in their preferred syntactic frames (Gahl, 2002). For example, Gahl (2002)reported that PWA made more comprehension errors about intransitive sentences that contained transitively- vs.intransitively-biased verbs. However, Russo et al. (1998) reported that PWA did not show on-line sensitivity tomismatches between transitivity bias and sentence stmcture in simple transitive and intransitive sentences. Russo etal. collapsed across sentence type, which is important because PWA seem to show an advantage for comprehensionof transitive stmctures (e.g., DeDe, 2011; Menn, 2000). Thus, effects of lexical biases may differ across sentencetypes.
