This research with the aim of scrutinizing fundamental notions of mapping hypothesis tried to investigate the comprehension of diverse complex syntactic structures in four age-, education-, and gender-matched Persian-speaking Broca's patients and eight matched healthy controls via conducting two tasks of syntactic comprehension and grammaticality judgment, in which subjects' comprehension of diverse complex structures was put into scrutiny. The tested structures included subject agentive, agentive passive, object experience, subject experience, subject cleft, and object cleft constructions. Our results, while corroborating the predictions of the mapping hypothesis, showed that in structures, in which linguistic elements were substituted and dislocated out of their canonical syntactic positions, namely, agentive passive, subject experiencer, object experiencer, and object cleft constructions, Broca's problems escalated. In contrast, in those structures whose constituent concatenations were aligned with canonical syntactic structures, namely subject agentive, and cleft structures, patients had above the chance performance. Ultimately, the theoretical and clinical implications of the study were discussed. |
