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失语症患者句子处理的词汇-语用影响，最终目标是开发失语症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）进一步了解词汇语用信息（例如，动词次范畴化和可解释性）制约句子加工;（2）表征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实现，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种条件下进行检查。本研究将解决以下假设：（1）相对于对照组，失语症患者将表现出降低的敏感性词汇语用信息的措施，在线句子理解;（2）失语症患者将受益于词汇语用信息的离线措施的理解。
