当我们移动时，视觉世界向我们移动。也就是说，自我运动通常会产生视觉信号（流），告诉我们自己的运动。但是这些信号会被我们的运动所扭曲：当我们移动时，视觉流实际上比我们静止时要慢，我们的周围环境从我们身边经过。虽然多年来，这些扭曲被解释为抑制流动，以促进对稳定世界的感知，但目前的研究表明，这些感知视觉速度的变化可能在测量我们自己的自我运动方面具有重要作用。具体来说，通过减慢自我运动过程中视觉流的表观速率，我们的视觉系统能够更精确地感知实际和预期流之间的差异。这在控制行动方面是有用的。
When we move, the visual world moves toward us. That is, self-motion normally produces visual signals (flow) that tell us about our own motion. But these signals are distorted by our motion: Visual flow actually appears slower while we are moving than it does when we are stationary and our surroundings move past us. Although for many years these kinds of distortions have been interpreted as a suppression of flow to promote the perception of a stable world, current research has shown that these shifts in perceived visual speed may have an important function in measuring our own self-motion. Specifically, by slowing down the apparent rate of visual flow during self-motion, our visual system is able to perceive differences between actual and expected flow more precisely. This is useful in the control of action.
