Eye tracking of observer-generated target movements.
When an observer moves his arm he shows more precise visual tracking of a target mounted on his fingertip-the eye lags behind the target less and makes fewer corrective saccades-than when he relaxes his arm and the experimenter moves it in a similar manner. Apparently the control system for eye movements can use outflow (efferent) signals in order to anticipate motion of the self-moved target.
