Dynamic visual acuity and performance in a catching task

Each of 30 Ss was given tests of dynamic and static visual acuity and then participated in a ball-catching task. Performance in the latter task was an inverted U-shaped function of duration of the occluded period, the time between the termination of the 80-msec. viewing period and the estimated onset of the "latency period" (the point in time at which the ball could no longer serve to cue Ss response). Dynamic and static visual acuity scores were not significantly correlated but, with static visual acuity partialled out, dynamic visual acuity and catching performance were significantly correlated.
