Visual perception during movements of the eyes and head

这个正在进行的研究项目的目标是对凝视转移和视觉感知之间的相互作用进行严格的理解。在过去的100年里进行的行为实验已经注意到，在被称为扫视的快速眼球运动期间，视觉感知发生了广泛的变化。这些包括刺激位置、时间甚至形状的虚幻变化。对于被称为平滑追踪的较慢的眼球运动，也发现了类似的感知效果。综上所述，这些效应揭示了动眼肌信号对视觉感知的明显影响。然而，它们通常是在相当人工的条件下进行研究的，在这种条件下，受试者被指示做一个单一的眼球运动，同时呈现一个孤立的视觉刺激。

The goal of this ongoing research program is to develop a rigorous understanding of the interaction between gaze shifts and visual perception. Behavioral experiments conducted over the last 100 years have noted a wide range of changes in visual perception around the time of fast eye movements called saccades. These include illusory changes in stimulus position, timing, and even shape. A similar range of perceptual effects has been found for slower eye movements known as smooth pursuit. Together these effects reveal a clear influence of oculomotor signals on visual perception. Yet they have typically been studied under rather artificial conditions, in which subjects are instructed to make a single eye movement, while an isolated visual stimulus is presented.
