摘要：Sentence processing deficits in aphasia become evident whenever patients have to rely on syntactic structure in order to derive the correct sentence interpretation. Hence, patients have difficulties in comprehending reversible non-canonical sentences. According to representational accounts (e.g. Grodzinsky, 1995), the impairment reflects disturbances in underlying syntactic representations. In contrast, processing accounts claim that representations are preserved, but sentence comprehension is acted by a processing weakness, resulting in slowed processing or intermittent breakdowns of the parser (cf Thompson & Choy，2009). Studies looking not only at offline performance, but also at on-line sentence processing (e.g. Caplan et al., 2007; Dickey et al., 2009; Hanne et ai., in press) provide new evidence towards structurally unimpaired but delayed syntactic processing in aphasia.
