DESCRIPTION (provided by applicant): The goal of the proposed studies is to investigate lexical-pragmatic influences on sentence processing in aphasic patients, with the eventual goal of developing a coherent model of sentence comprehension in aphasia that will provide a framework for the assessment and treatment of patients with disordered sentence comprehension. The specific aims are: (1) To advance knowledge of how lexical-pragmatic information (e.g., verb subcategorization and plausibility) constrain sentence processing; and (2) To characterize changes in the function of such information associated with aphasia. These aims will be addressed through studies of syntactic processing in which participants' on-line and off-line comprehension of garden path sentences will be examined under several conditions. This study will address the following hypotheses: (1) Relative to controls, aphasic patients will demonstrate reduced sensitivity to lexicalpragmatic information in measures of on-line sentence comprehension; and (2) Aphasic patients will benefit from lexical-pragmatic information in off-line measures of comprehension.

描述（由申请人提供）：拟议研究的目标是调查词汇语用对失语症患者句子处理的影响，最终目标是开发失语症患者句子理解的连贯模型，为评估和治疗句子理解障碍患者提供框架。具体目标是：（1）增进对词汇语用信息（例如动词子分类和合理性）如何限制句子处理的了解； (2) 描述与失语症相关的此类信息功能的变化。这些目标将通过句法处理的研究来实现，其中将在多种条件下检查参与者对花园路径句子的在线和离线理解。本研究将提出以下假设：（1）相对于对照组，失语症患者在在线句子理解测量中表现出对词汇语用信息的敏感性降低； (2)失语症患者将受益于离线理解测量中的词汇语用信息。
