Relationships between faces and body motor patterns in a group of captive pigtailed macaques (Macaca nemestrina)
article
The paper describes facial displays and body motor patterns observed in a group of five captive pigtailed macaques during dyadic aggressive and courtship interactions. Correlations between facial displays and body motor patterns were studied quantitatively in order to establish the predictive value of a facial display for the behaviour of the performer. Results indicate that each of the facial displays is largely restricted to a certain type of interaction. Within an interaction of a certain type, the facial displays provided a rather precise prediction of how the performer continued the interaction. Furthermore, the predictive value varied quantitatively between subjects addressing the same partner as well as within the subject when addressing different partners. It is argued that various faces probably function as much as a signal to the interaction partner as to the other individuals which are likely to be nearby and might interfere with the interaction. ?? 1979 Japan Monkey Centre.
