The image recollection of shooting of Japanese archery was measured by a single square voltage pulse method (SSVP) and near infrared oxygen metabolism monitor. In the case of Japan student champion of Japanese archery '93, AP, the autonomic nervous system related parameter, increased at imaging of "uchiokoshi" the stage of lifting up the bow, and decreased at "kai", balancing state and "hanare", drawing stage. However, when measuring with expert of Japanese archery with 5 dan (grade), AP exhibited only slight changes indicating severe balancing and strong self-control throughout the whole imaging stage. The striking contrast of AP behaviour compared with archery case was observed in the image recollection of chess game, which showed considerable decrease of AP suggesting calm state with deep concentration. The difference between imaging of archery and chess game can be interpreted as follows. Japanese archery is a sport essentially dominant of stretching movement and imaging of it may cause sympathetic nerve excited, whereas imaging of chess game is rather visual and abstract mental task.
