Janken, by which service side was decided for single match of table tennis, was observed when female subjects (first year student; mean age was nineteen years old) had a lesson for physical education. Among 37 subjects who played the match by their right hands, eight subjects played janken by their left hands, but twenty-six subjects played it by their right hands shifting their rackets from their right hands to their left ones. There were no differences between the two groups in a questionare of laterality which consisted of 40 items of daily movement. Subjects was asked which side they often used for each item. Y-G personality inventory, however, showed significant differences between the two groups. The significant differences were observed on the C, G, and R scales at five persent level, and on the Ag and A scales at one percent level. This indicates that the subjects who played janken by their right hands have more active and extroverted personality than the subjects who played it by their left hands. And the latter subjects seem to be less aggressive, changeless in feeling, and quiet. The constantly used hand couldn't be decided only for three subjects. When the subjects was asked which hand they had used to play janken before the match, only fourteen subjects out of the twenty-six subjects who played it by their right hands made correct answers. The incorrect answer would be made because of the lack of complete image of the situation. Especially they couldn't image the active feeling on the match condition. It is considered that the psychological set against the opponent caused the shift of the racket to play janken by the right hand for active subjects only, but some of them couldn't image the situation well and made incorrect answers. There remains, however, some problems. Why the more extroverted subjects, who felt the active feeling, changed the racket and played janken by their right hands is not explained now. And it is also further problem whether the subjects, who played janken at the table tennis match by their right hands, play it by the same hands at the tennis match or at the badminton match.
