Anticipation of Movement Outcome Through Perception of Movement Kinematics

The influence of three types of visual displays and the relative importance of different body segments for the anticipation of movement outcome was investigated. Twelve novice and 13 expert tennis players participated in three experiments. In Experiment 1, the players observed the movements of an expert player (performer) who performed four strokes in three types of display (five, 2-d, and point-light). The results showed that the expert players were more accurate and faster in the anticipation than the novice players. Also, the expert players were more accurate and faster when they observed the performer in five display, whereas the novice players anticipation accuracy did not differ across the displays. in Experiment 2, a kinematic analysis was performed to find the differences in the movement pattern produced for the four strokes. Finally, in Experiment 3, various body parts were occluded to determine what influence they had on the observer's anticipation of movement outcome. The results of Experiment 2 showed that the relative motion between the forearm and racquet greatly differed between the strokes, and the occlusion of the forearm and racquet in Experiment 3 significantly reduced the anticipation accuracy of the expert players. The findings are discussed from a perception and action framework.
