Social play and play-soliciting by infant canids

摘要: The development of social interaction was studied in infant coyotes, beagles, and wolves. In this paper, play behavior is discussed. Social may be characterized a number ways: (i) actions from various contexts are incorporated into labile (unpredictable) temporal sequences; (ii) the “play bout” typically preceded by metacommunicative signal which indicates “what follows play”; these signals also observed during bout; (iii) certain repeated performed an exaggerated manner; (iv) activity appears “pleasurable” to players. By comparing three species, some insight dynamics gained. Coyotes were least successful soliciting play. When they did play, 90% all bouts had been previously solicited. tended use most frequently. This trend not beagles or By taking account fact that coyotes significantly more aggressive than either wolves differential ontogeny can explained. Some functions canids discussed, it concluded valid class lends itself nicely quantitative study.
