Utilizing a simulated table-tennis task, improved visual and auditory acuity of a group of 13 Ss was found after a playing period of 10 min. 2 passive control groups, 1 observing ball flight and the other a static display, showed no significant improvements in either visual or auditory acuity. The results are interpreted in terms of sensory facilitation brought about by increased arousal resulting from gross-bodily activity.
