Action and vision are known to be tightly coupled with each other. In a previous study, we found that repeatedly grasping an object without any visual feedback might result in a perceptual aftereffect when the object was visually presented in the context of a perceptual judgement task. In this study, we explored whether and how such an effect could be modulated by presenting the object behind a transparent barrier. Our conjecture was that if perceptual judgment relies, in part at least, on the same processes and representations as those involved in action, then one should expect to find a slowdown in judgment performance when the target object looks to be out of reach. And this was what we actually found. This indicates that not only acting upon an object but also being prevented from acting upon it can affect how the object is perceptually judged.

行动与视觉紧密相连。在先前的研究中，我们发现，如果在感知判断任务的上下文中以视觉方式呈现对象，则在没有任何视觉反馈的情况下反复抓住对象可能会导致感知后效。在这项研究中，我们探讨了通过在透明障碍物后面显示物体是否可以以及如何调节这种效果。我们的推测是，如果知觉判断至少部分地依赖于与行动所涉及的过程和表示相同的过程和表示，那么当目标对象看起来遥不可及时，人们应该期望发现判断性能下降。这就是我们真正发现的。这表明，不仅作用在物体上，而且被阻止作用在物体上，也会影响感知物体的方式。
