It is known that stimuli near the hands receive preferential processing. In the present study, we explored changes in early vision near the hands. Participants were more sensitive to low-spatial-frequency information and less sensitive to high-spatial-frequency information for stimuli presented close to the hands. This pattern suggests enhanced processing in the magnocellular visual pathway for such stimuli, and impaired processing in the parvocellular pathway. Consistent with that possibility, we found that the effects of hand proximity in several tasks were eliminated by illumination with red diffuse light-a manipulation known to impair magnocellular processing. These results help clarify how the hands affect vision.
