DISCOURSE PERFORMANCE AFTER RIGHT BRAIN DAMAGE

自然发生的交流往往采取话语的形式 例如友好交谈。 的成功 服务于社交和信息目的的对话是 很大程度上取决于参与者是否遵守 礼貌的话语 不恰当的评论或措辞会转移注意力 注意从字面上的信息，更重要的是，可以破坏 说话的人之间的社会联系。 遵守这些公约 需要了解是什么影响了别人的感受， 知道别人知道什么，不知道什么， 在不同的话语语境中，人们的感受是不同的 和知识 单侧脑损伤对患者生活质量的影响 这些方面的成功。 最感兴趣的患者是 那些由于中风而持续右半球脑损伤（RHD）的人 但他们没有失语症。 无脑损伤的对照组将 提供主要对照组， 大多数拟议任务的要求，但右侧和（非失语症）左侧 在可能的情况下，将对额前损伤患者进行检测， 功能定位的信息，失语症LHD患者也是如此， 大脑中动脉区域病变。 计划研究的结果 将为脑损伤患者的精神生活提供一个窗口 也会帮忙的我们知道脑损伤是如何损害社会的， 推理，这是RHD患者及其 家庭

Naturally occurring communication very often takes the form of discourse such as, for example, a friendly conversation. The success of conversations that serve social as well as informational purposes is largely determined by whether the participants obey the rules governing polite discourse. Inappropriate comments or word choices can divert attention from the literal message and, more importantly, can undermine the social bond between the people speaking. Abiding by these conventions requires understanding what affects the feelings other people, keeping track of what other people know and do not know, and knowing what is appropriate in different discourse settings defined by people's feelings and knowledge. The effects of unilateral brain injury on patients' success with these aspects of discourse. The patients of most interest are those who have sustained right hemisphere brain damage (RHD) due to stroke but who do not have aphasia. Non brain-damaged control subjects will provide the primary comparison group in light o the heavy linguistic demands of most of the proposed tasks, but right and (nonaphasic) left prefrontally damaged patients will be tested when possible to provide information on localization of function, as will aphasic LHD patients with middle cerebral artery territory lesions. Results from the planned studies will provide a window onto the mental life of the brain-injured individual and will help. us understand the ways in which brain injury impairs social reasoning which is a major source of difficulty for RHD patients and their families.
