许多运动任务涉及与移动物体的相互作用。当观察者（即，自运动伴随着物体运动，光流场包括由于自运动的分量和由于物体运动的分量。为了让移动的观察者感知到其他物体相对于静止环境的运动，视觉系统可以恢复物体运动分量-也就是说，它可以排除自我运动的影响。原则上，这可以使用视觉自运动信息、非视觉自运动信息或两者的组合来实现。在这项研究中，我们报告的证据表明，视觉信息的速度（实验1）和方向（实验2）的自我运动在恢复的对象运动组件中发挥了作用，即使非视觉自我运动信息也是可用的。然而，如果受试者完全依赖于视觉自我运动信息，这种影响的程度要小于人们的预期。结合以往的研究，我们得出结论，当自我运动是真实的和积极产生的，视觉和非视觉的自我运动信息有助于感知的对象运动。我们还考虑了这一过程中的视觉引导拦截和避免移动物体的可能作用。
Many locomotor tasks involve interactions with moving objects. When observer (i.e., self-)motion is accompanied by object motion, the optic flow field includes a component due to self-motion and a component due to object motion. For moving observers to perceive the movement of other objects relative to the stationary environment, the visual system could recover the object-motion component – that is, it could factor out the influence of self-motion. In principle, this could be achieved using visual self-motion information, non-visual self-motion information, or a combination of both. In this study, we report evidence that visual information about the speed (Experiment 1) and direction (Experiment 2) of self-motion plays a role in recovering the object-motion component even when non-visual self-motion information is also available. However, the magnitude of the effect was less than one would expect if subjects relied entirely on visual self-motion information. Taken together with previous studies, we conclude that when self-motion is real and actively generated, both visual and non-visual self-motion information contribute to the perception of object motion. We also consider the possible role of this process in visually guided interception and avoidance of moving objects.
