Abstract 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.

Introduction Action and vision are known to be tightly coupled with each other. Many studies show that visual perception might affect action. For instance, when visually presented with various objects, participants are faster in performing a compatible action, even when the action does not pertain to the viewed object (Costantini, Ambrosini, Tieri, Sinigaglia, and Committeri 2010; Ellis and Tucker 2000; Tucker and Ellis 1998, 2001,2004). Some studies indicate that the other way around could be true as well, with action affecting visual perception (Craighero, Fadiga, Rizzolatti and Umiltà 1999; Hecht, Vogt and Prinz 2001; Cardoso-Leite, Mamassian, SchützBosbach, Waszak 2010; Brockmole, Davoli, Abrams, and

In a previous series of experiments, we explored the action–vision coupling by investigating whether and how repeatedly performing a reach-to-grasp action might influence the perceptual judgement on a relevant visual feature of an object (i.e. a mug), such as its shape (its being handled or not). We found that repeated grasping actions produced a perceptual after-effect, with participants being slower in detecting the visually presented handled mugs when their handles were oriented congruently with the grasping hand. Interestingly, the same effect did not occur when participants were asked to de
