摘要: Online visual control of the direction rapid reaching movements was assessed by evaluating how human subjects reacted to shifts in seen hand position near movement onsets. Participants (N=10) produced saccadic eye and arm (mean duration = 328 ms) towards a peripheral target complete darkness. During saccade, feedback could be shifted 1, 2, 3 or 4 cm perpendicularly main direction. The resulting discrepancies between proprioceptive information about were never consciously perceived subjects. Following shifts, trajectories deviated from those condition (without shift) order bring closer target. Globally, deviations corresponded 45% regardless their magnitude duration. This finding highlights not only efficiency processing online motor but also underlines significant contribution limb proprioception.
