我们主动扫描我们的环境与快速弹道运动称为扫视，这创造了大和快速位移的图像在视网膜上。在扫视时，视觉在许多方面变得短暂扭曲：短暂闪现的刺激在空间和时间上被移位，空间和时间间隔似乎被压缩。在这里，我们应用分类图像的心理物理技术来研究扫视过程中视觉机制的时空动态。我们发现，扫视导致分类图像的严重失真。在扫视眼球运动开始之前，图像的正叶在空间和时间上都变得扩大，并且也以系统的方式向扫视前注视移动（在空间上）并且在时间上预期约50 ms。瞬时重组创建了在扫视时以扫视诱导的运动的方向定向的时空组织，提供了一种潜在的机制，用于整合跨越扫视的刺激，在面对恒定的眼球运动时促进稳定和连续的视觉。
We actively scan our environment with fast ballistic movements called saccades, which create large and rapid displacements of the image on the retina. At the time of saccades, vision becomes transiently distorted in many ways: Briefly flashed stimuli are displaced in space and in time, and spatial and temporal intervals appear compressed. Here we apply the psychophysical technique of classification images to study the spatiotemporal dynamics of visual mechanisms during saccades. We show that saccades cause gross distortions of the classification images. Before the onset of saccadic eye movements, the positive lobes of the images become enlarged in both space and in time and also shifted in a systematic manner toward the pre-saccadic fixation (in space) and anticipated in time by about 50 ms. The transient reorganization creates a spatiotemporal organization oriented in the direction of saccadic-induced motion at the time of saccades, providing a potential mechanism for integrating stimuli across saccades, facilitating stable and continuous vision in the face of constant eye movements.
