Manual Asymmetries in Visually Directed Aiming

Several authors (e.g., Flowers, 1975; Roy, 1983) have suggested that manual asymmetries in visual aiming stem from differences in the ability of the hand-hemisphere systems to use visual feedback. Specifically, it has been proposed that the right-hand system is faster at processing visual feedback. The two experiments reported here were designed to examine this hypothesis directly by manipulating visual feedback. In the first study subjects …
