It is known that we move our eyes about three or four times per second. From the fact of saccadic suppression, it can be said we are getting 3 or 4 still pictures of somewhat different aspeccts of the outer world. The fact that we perceive stable world even in such a dynamic situation tells that our cognitive system somehow integrate visual information across saccades. Our working hypothesis is this: There is a visual buffer in which incoming visual inputs are integrated to construct a stable visual world being aided by our knowledge of the world.A set of equipments was prepared to present successive visual stimuli on a computer display and record eye positions simultaneously.In a pilot study, a horizontal line segment a was presented to the left of a fixation point for a short duration. After a saccade which moved eyes to another fixation point which located at the left of the former segment a, a vertical line segment b appeared at the same area where a was located. Observer's task was to estimate numerically at which point on a the second segment b appeared crossed. It was found the estimation was based on physical instead of retinotopic positions of the segmen ts in a light room condition. The effect of surrounding visual context must be examined.A related experiment revealed that fixation on one of the two objects moving relatively to each other enhanced perceiving of movement of the nonfixated object.

我们的眼睛每秒钟移动三到四次。从扫视抑制的事实来看，可以说我们得到了3或4张外部世界不同方面的静态图片。即使在这样一个动态的情况下，我们也能感知到稳定的世界，这一事实表明我们的认知系统以某种方式整合了眼跳中的视觉信息。我们的工作假设是：存在一个视觉缓冲区，在这个缓冲区中，输入的视觉信息在我们对世界的认识的帮助下被整合，从而构建一个稳定的视觉世界。当眼扫视到位于前线段a左侧的另一注视点时，在a所在的同一区域出现一条垂直线段B。观察员的任务是从数字上估计a上第二个线段B出现交叉的点。发现该估计是基于在光照室内条件下的节段的物理位置而不是视网膜位置。相关实验表明，注视两个相对运动的物体中的一个，会增强对非注视物体运动的感知。
