This project explores how attention in normal individuals is mediated by the inter- action of the attention systems of the cerebral hemispheres. There is considerable evidence that the hemispheres differ in their attentional characteristics, but it is not known how the single "spotlight" of attention that we experience emerges from the interaction of the hemispheres. This project will help advance our understanding of the relationship between brain and mind, and will ultimately help us to understand the effects of brain damage on cognitive function. Interhemispheric interaction in visuo- spatial attention will be studied with brain event-related potentials (ERPs) and standard behavioral measures. Measurements of ERP components will permit the study of neural systems involved in various types of attentional processing. Measures of "hemispheric utilization bias", which is likely to be an important factor in interhemispheric interaction, will also be used. The proposed experiments examine different aspects of interhemispheric interaction in attention: the processing stages involved, the influence of task difficulty and stimulus probability, trial-to-trial switching, and the shifting of attention. Through this research, we aim to develop a model of how attention is mediated by interhemispheric interaction.

这个项目探索了正常人的注意力是如何通过 大脑半球注意力系统的相互作用。 有相当多的证据表明，这两个半球在 注意特征，但目前还不知道如何单一 我们体验到的注意力的“聚光灯”从互动中浮现出来 在两个半球之间。这个项目将有助于增进我们对 大脑和大脑之间的关系，最终将帮助我们 了解大脑损伤对认知功能的影响。 将研究视觉-空间注意中的大脑半球间相互作用 脑事件相关电位(ERPs)和标准行为 措施。对ERP组件的测量将允许研究 神经系统参与了各种类型的注意力处理。 衡量“半球利用偏差”，这很可能是一种 半球间相互作用中的重要因素，也将被使用。 拟议的实验考察了大脑半球间的不同方面。 注意中的交互作用：涉及的加工阶段，影响 任务难度和刺激概率，试验到试验切换， 以及注意力的转移。通过这项研究，我们的目标是开发 注意力如何通过大脑半球间的相互作用来调节的模型。
