项目摘要

DESCRIPTION (provided by applicant): This project is designed to assess the role of perceptual binding (combining identity and location information) in language and how attentional constraints may affect this. This includes looking at behavioral processes in stroke and non-stroke individuals on tasks that require binding as well as tasks that do not require binding. Accordingly, the specific aims of the project focus on determining if individuals with aphasia perform less accurately on tasks that require binding versus those that do not. The long-term goal of this project is to provide a better understanding of the role of binding and attention in language, which will lead to further imaging studies of the functional neurocognitive underpinnings for these processes. Together, these behavioral tasks provide complimentary data that should demonstrate a more complete picture of the processes of attention and binding in individuals with aphasia. Experiment 1 is designed to investigate whether the phenomenon of extinction is present for individuals with aphasia and non-brain damaged controls on tasks that require binding. Experiment 2 will use the same stimuli from Experiment 1; however, binding will no longer be required. On these tasks, individuals with aphasia and control participants will be required to count only and will therefore not have to bind together identification and localization. Experiment 3 will control for the amount of resources to be allocated, while still not requiring binding. This will occur by having patients identify and count the items presented, as opposed to localizing. By investigating the role of attention and binding in aphasia, a further understanding of the underlying deficits that may contribute to aphasia may emerge. In addition, such information could impact the field by leading to further development of efficient and efficacious rehabilitation strategies through a better understanding of the theoretical underpinnings of aphasia.
描述(由申请人提供):该项目旨在评估感知绑定(结合身份和位置信息)在语言中的作用以及注意力约束如何影响它。这包括观察中风和非中风个体在需要绑定的任务以及不需要绑定的任务上的行为过程。因此,该项目的具体目标侧重于确定失语症患者在需要结合的任务上与不需要结合的任务上的表现是否不太准确。该项目的长期目标是更好地理解语言中的结合和注意力的作用,这将导致对这些过程的功能性神经认知基础的进一步成像研究。这些行为任务共同提供了补充数据,可以更全面地展示失语症患者的注意力和结合过程。实验1旨在研究失语症和非脑损伤个体在执行需要结合的任务时是否存在消退现象。实验 2 将使用与实验 1 相同的刺激;但是,不再需要绑定。在这些任务中,失语症患者和对照参与者将只需要计数,因此不必将识别和定位结合在一起。实验 3 将控制要分配的资源量,同时仍然不需要绑定。这将通过让患者识别和计算所呈现的项目来实现,而不是定位。通过研究注意力和束缚在失语症中的作用,可能会进一步了解可能导致失语症的潜在缺陷。此外,这些信息可能会通过更好地理解失语症的理论基础来进一步开发高效和有效的康复策略,从而对该领域产生影响。
