Beschreibung:
It is well-known that individuals with aphasia (IWA) have difficulties understanding sentences that involve non-adjacent dependencies, such as object relative clauses or passives (Caplan, Baker, & Dehaut, 1985; Caramazza & Zurif, 1976). A large body of research supports the view that IWA’s grammatical system is intact, and that comprehension difficulties in aphasia are caused by a processing deficit, such as a delay in lexical access and/or in syntactic structure building (e.g., Burkhardt, Piñango, & Wong, 2003; Caplan, Michaud, & Hufford, 2015; Caplan, Waters, DeDe, Michaud, & Reddy, 2007; Ferrill, Love, Walenski, & Shapiro, 2012; Hanne, Burchert, De Bleser, & Vasishth, 2015; Love, Swinney, Walenski, & Zurif, 2008). The main goal of this dissertation is to computationally investigate the processing sources of comprehension impairments in sentence processing in aphasia. In this work, prominent theories of processing deficits coming from the aphasia literature are implemented within two cognitive models of sentence processing –the ...
