SENTENCE PRODUCTION IN APHASIA

本项目的目的是研究词汇和 失语症句子产生中的句法因素 词汇因素将 与名词相关的语义（noun-related semantics）， 与动词有关的（动词论元结构）。 句法效果 要探讨的是那些与语序有关的问题， 动词的施事/施动者在动词之前或之后（成分顺序）。 的 这些因素在决定句子产生中的作用将是 检查正常人和失语症患者，使用一系列的 不同的任务旨在提供关于失语症的会聚证据 患者的表现。 这些因素将作为独立因素使用 实验中的变量，其中产生词汇项目的能力， 语法成分，句法结构和主题角色将是 依赖措施。 这项研究旨在提供有关句子的基本数据， 失语症的治疗方法目前还没有。 这些数据将 与正常的句子产生模式有关。 他们最终可能 用于指导针对改善失语症患者的句子的治疗 生产能力。

The goal of this project is to investigate the effects of lexical and syntactic factors in sentence production in aphasia. Lexical factors will be divided into those associated with nouns (noun-related semantics), and those associated with verbs (verb argument structure). Syntactic effects to be explored are those associated with word orders that place the agent/actor of a verb before or after the verb (constituent order). The role that these factors play in determining sentence production will be examined for normal subjects and aphasic patients, using a series of different tasks designed to provide converging evidence regarding aphasic patients' performances. These factors will be used as independent variables in experiments in which the ability to produce lexical items, grammatical elements, syntactic structures, and thematic roles will be the dependent measures. The research is designed to provide basic data regarding sentence production in aphasia that is not presently available. These data will related to models of normal sentence production. They may ultimately be useful in guiding therapy directed at improving aphasic patients' sentence production abilities.
