Abstract
This study addresses the question of whether peripheral vision is involved in the control of hand trajectory direction during an aiming task performed at high speed. Ten adult subjects aimed at targets in various positions by making a punching movement with their hand. The experimental conditions were varied so that different parts of hand trajectory could be seen in the peripheral field. Two movement times were applied: < 130 ms and 250-300 ms. A directional correction of trajectory can be made by means of on-line peripheral feedback, even with movements as brief as 110 ms.
