is in general agreement with the conception that visual cues operate in movement control in the open-loop more than in the closed-loop mode ( Jeannerod & Prablanc, 1983). Accordingly, vision would be more suited for generating a short-term spatial "map," which could be used as a reference for final limb position. During execution of the movement, at least during its early part, additional information could be gained from the visual feedback generated by view of the moving limb. This visual sampling could possibly act via an increase of the gain of the somatosensory feedback loop, and be used to improve final precision.
