Abstract: Two experiments examined the coordination of eye and hand movements in right-handed subjects who completed single (Experiment 1) and reciprocal (Experiment 2) aiming movements with each hand. In both experiments eye movements preceded hand movement, and arrived well in advance of the hand to allow pickup of visual information about relative position of the hand and target to correct te ongoing movement. With reciprocal aiming differences emerged between the hands. A right hand advantage was found for movement execution, and a left hand advantage for movement initiation. Manual asymmetries were not due to practice differences between hands. Subjects made larger initial saccades and more corrective saccades when aiming with the left hand. The pattern of eye-hand coordination was consistent with Woodworth's (1899) two component model of limb control, and at odds with models of limb control which suggest that online visual pickup is of minor importance.
