The influence of intermittent vision on manual aiming.

Two experiments were conducted to examine the influence of intermittent vision on right and left hand aiming. In Experiment 1, increased visual occlusion times led to a steady deterioration in performance that was most pronounced for high index of difficulty targets. Longer visual sample times only partially compensated for this effect (Experiment 2). It is suggested that a short-lived visual representation of the movement environment may in some cases provide a reasonable, although not 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.
