PROCESSING STREAMS IN EARLY VISION

描述：该项目研究了运动中涉及的视觉通路 perception.将使用几种方法来评估属性是否 例如颜色或立体声由低级运动系统或高级运动系统感测 水平注意力特征跟踪系统。此外，反对议案 刺激将测试低水平的机制是否代表一个单一的类 运动探测器或几个不同的类别。皮质测试 色盲患者将分析对颜色刺激的运动反应 它不依赖于颜色感觉。该提案还将评估 基于注意跟踪的高级运动系统 涉及注意力而不是眼球运动的系统。第二 该项目的一半将分析关注机制的性质， 包括注意跟踪是否是真实的运动系统， 展示了预测方面。此外，建议开展研究， 在跟踪过程中测量注意力的空间分辨率。

DESCRIPTION: The project examines the visual pathways involved in motion perception. Several methods will be used to asses whether an attribute such as color or stero is sensed by a low-level motion system or a high level attentional feature tracking system. In addition, opposing motion stimuli will test whether low level mechanisms represent a single class of motion detectors or several distinct classes. Tests of cortically color blind patients will analyze the motion response to color stimuli which do not rely on color sensations. The proposal will also evaluate the high level motion system based on attentive tracking - a pursuit system that involves attention rather than eye movements. The second half of the project will analyze the nature of the attentive mechanism, including whether attentive tracking is a real motion system in that it demonstrates predictive aspects. In addition, studies are proposed to measure the spatial resolution of attention during tracking.
