Fundamental notions of mapping hypothesis and canonicity were scrutinized in Persian-speaking aphasics.
To this end, the performance of four age-, education-, and gender matched Persian-speaking Broca's patients and eight matched healthy controls in diverse complex structures were compared via the conduction of two tasks of syntactic comprehension and grammaticality judgment.
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.
The number of predicates in a sentence, predicate types (psychological and agentive), as well as semantic heuristics and canonicity all by all could be regarded as the major culprits for aphasics' poor performance.
对说波斯语的失语症患者的映射假设和规范性的基本概念进行了仔细研究。
为此，通过进行句法理解和语法正确性判断这两项任务，比较了四名年龄、教育程度和性别匹配的说波斯语的布罗卡氏失语症患者以及八名匹配的健康对照者在各种复杂结构中的表现。
测试的结构包括主语施事、施事被动、宾语体验、主语体验、主语分裂和宾语分裂结构。我们的结果在证实映射假设预测的同时，表明在语言元素被替换并偏离其规范句法位置的结构中，即施事被动、主语体验者、宾语体验者和宾语分裂结构中，布罗卡氏失语症患者的问题加剧。相比之下，在那些成分连接与规范句法结构一致的结构中，即主语施事和分裂结构中，患者的表现高于随机水平。最后，讨论了该研究的理论和临床意义。
句子中的谓语数量、谓语类型（心理和施事）以及语义启发法和规范性都可被视为导致失语症患者表现不佳的主要因素。
