STUDY ON MOTION PERCEPTION IN SPORT SCENES USING BIOLOGICAL MOTION

Two experiments were conducted to investigate spatio-temporal characteristic of perception of karate offensive action using biological motion. In Experiment 1, the proportion of correct identification for karate attacks (high/middle, left/right, kick/punch) was measured by manipulating the number of point lights constituting biological motion stimuli. In Experiment 2, stimulus presentations were cut off at various timings. The results of those two experiments indicated that recognition of attack motion from point-light stimuli reflected spatio-temporal information in the stimuli, with little influence of anticipation from earlier motion.
