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）：本研究旨在探讨词汇语用对失语症患者句子加工的影响，最终目标是建立一个连贯的失语症句子理解模型，为评估和治疗失语症患者提供一个框架。具体目标是：(1)增进对词汇语用信息（如动词子类化和合理性）如何约束句子加工的认识；(2)描述与失语症相关的这些信息的功能变化。这些目标将通过句法加工的研究来解决，在这些研究中，参与者对花园小径句子的在线和离线理解将在几个条件下进行检查。本研究将提出以下假设：(1)相对于对照组，失语患者在在线句子理解测试中对词汇语用信息的敏感性会降低；(2)失语患者将受益于离线理解测试中的词汇-语用信息。
