Basic research for developing sport psychophysics

Excellent performance of top-class athletes is due not only to their physical abilities but also to their expertise perception acquired through practice and experience. The head investigator of this project proposed to study expertise perception of athletes by psychophysical methods, that is sport psychophysics. This project was to conduct basic research for developing sport psychophysics, and for this purpose expertise perception of karate athletes was experimentally investigated. Results obtained in this 3-year project are summarized as follows.1.Using realistic stimuli (videotaped offensive performance) and non-realistic stimuli, we showed fast reaction and accurate prediction of karate athletes concerning opponent's attack (Mori, Ohtani, Imanaka, 2002).2.Following occulomotor theory of induced motion, we predicted and confirmed that the magnitude of induced motion was larger for karate athletes than for novices (Seya & Mori, 2002).3.In detection and discrimination tasks of peripheral targets during pursuit of a moving stimulus, we found that karate athletes were different from novices in reaction time, accuracy, and eye movement (Seya & Mori, 2003).These results have been published in journal articles and a book chapter, and they have also been presented in the meetings of Japanese Psychological Association (Higashi-Hiroshima, 2002 ; Tokyo, 2003), Japanese Society of Sport Psychology (Tokyo, 2001 ; Tsukuba, 2003), IEICE Human Information Processing (Sendai, 2002, 2003), and Psychonomic Society (Vancouver, 2003).
