多目标视觉追踪中物体属性加工的眼动研究*

采用多目标视觉追踪任务(MOT)，探讨物体颜色特征对视觉追踪的影响，同时记录被试的眼动情况，探讨追踪过程中颜色特征对眼动模式的影响。结果发现，视觉追踪机制能够对物体的颜色特征进行加工，但加工程度受制于目标物与分心物之间的特征竞争关系。在物体颜色特征条件下，视觉系统采用知觉组织加工策略，以被追踪目标构成的多边形中心为注意中心。在对物体颜色特征的加工中，内源性注意与外源性注意相互影响。

The Study of Eye Movements in Features Process During Multiple Object Tracking

The study investigated how the object color are processed by visual attention and presented by the eye movements during a multiple-object tracking (MOT) task,in which their eye movements were monitored.Results indicated that objects color could be encoded by visual system, but the degree which the color assisted tracking was limited by the competitive relationships between targets and distractions. The visual system used perceptual grouping strategy to fixate closer to the center of the polygon formed by the targets during MOT. The color of targets attract more exogenous attention , visual attention was influenced by exogenous and endogenous attention.
