PROCESSING STREAMS IN EARLY VISION

描述：该项目研究运动中涉及的视觉通路。 感知力。将使用几种方法来评估属性是否 例如颜色或立体，由低水平运动系统或高水平运动系统感测 水平注意特征跟踪系统。此外，反对议案 刺激物将测试低级机制是否代表单个类别 运动探测器或几个不同的类别。大脑皮层测试 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。该提案还将对 基于注意力跟踪的高水平运动系统--A追踪 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注意力机制的性质， 包括注意力跟踪是否是真正的运动系统，因为它 演示预测性方面。此外，还建议进行以下研究： 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.
