Visual processing is known to be enhanced at the end point of eye movements. Feedback within the oculomotor system has been shown to drive these alterations in visual processing. However, we do not simply view the world; we also reach out and interact using our hands. Consequently, it is not surprising that visual processing has also been shown to be altered in near‐hand space. A growing body of work documents a myriad of alterations in near‐hand visual processing, with little consensus on the neural underpinnings of the effect of the hand. Since movement of the eyes and hands is governed by parallel frontoparietal networks and since within the oculomotor system feedback from these motor control regions has been shown to drive enhanced visual processing at saccade end points, it is plausible that a similar feedback mechanism is at play in near‐hand improvements in visual processing. Here, we compare and contrast oculomotor‐driven and hand‐driven changes in visual processing and provide support for the hypothesis that feedback within the reaching and grasping systems enhances visual processing near the hand in a novel way.
