THE INFLUENCE OF INTERMITTENT VISION ON MANUAL AIMING

Two experiments were conducted to examine the influence of intermitten t vision on right and left hand aiming. In Experiment 1, increased vis ual occlusion times led to a steady deterioration in performance that was most pronounced for high index of difficulty targets. Longer visua l sample times only partially compensated for this effect (Experiment 2). It is suggested that a short-lived visual representation of the mo vement environment may in some cases provide a reasonable, although no t perfect, substitute for direct visual pickup. In Experiment 2, there was some indication that the right hand system may be faster at using visual information than the left hand system.
