It has been previously shown that planning or performing an action can affect visual processing. In studies reporting partial repetition cost or inverse-compatibility effects the detection of the target is impaired if the target is congruent with the action (inhibition effect). However, in more complex designs a facilitation effect is observed (target processing is enhanced if it is compatible with the action). The present study investigated how a recently executed grasp affects the visual search for a target object whose size is congruent or incongruent with the grasp type. In Experiment 1 the subjects were instructed to perform a pre-search grasp, which had an inhibitory effect on their search in congruent objects. In Experiment 2 we tested whether the inhibitory effect can be achieved in simple object detection task. In Experiment 3 no action was performed before the search (action was still performed when target was found) and no action-effect was observed.
