| Research Abstract |
This study aimed at calrifying social techniques of communication among Japanese monkeys, analyzing video records of social interactions. This study focused on social play which has an important role for the development of social manipulation techniques. Data were collected at Funakoshi-yama, Hyogo prefecture, using 8 mm video recorder. Social technique used in play and its significance for social manipulation were discussed.
The social techniques for play initiation were summarized as follows : the individual who wanted to play did not force the partner to play, and he waited until the partnert began to contact with him. These techniques involved behavior inhibition. Behavior inhibition was observed also during rough and tumble play. The playrs inhibited to bite strongly, and when one of the partners stopped moving, the other also stopped his action. Self-handicapping which involved behavioral inhibition for the stronger side was the important technique for playrs to maintain their play.
In play scenes, the situations such as clear play, pause, paraplay, pause occurred repeatedly. Repeated occurrence of pause, which had a calming effect, functioned for prolonging play interactions.
The relationship between play and technique was investigated, analyzing social play and stone play observed at Funakoshi-Yama. Behavior flexibility and behavioral repetition were the important characterictics which affected acquisition of complecated techniques.
