Calming an aggressor through spontaneous post-conflict triadic contacts: appeasement in Macaca tonkeana.
Peaceful third-party interventions usually occur after an aggressive encounter and can
be directed toward the victim or the aggressor. Macaca tonkeana, a cercopithecine
species characterized by high levels of tolerance, frequently engage in consolatory
contacts, which both calm the victim and reduce the probability of further attacks
against him/her. Other post-conflict affiliative interventions such as reconciliation and
quadratic affiliation are also common in this species. However, little attention has been
given to contacts directed toward the aggressor. Here,weexplore the role of bystander
affiliative interventions toward the aggressor in influencing the affective state of the
aggressor and the consequences of triadic interventions at group level. We found that
triadic post-conflict affiliation occurred independently from the intensity of the conflict
and that it was more frequent in absence of the conciliatory contact between the
opponents (reconciliation). Bystanders showed a higher amount of post-conflict
affiliation toward low ranking aggressors. Post-conflict triadic affiliation functioned as
a tension reduction mechanism by lowering the arousal of the aggressor, which less
frequently engaged in renewed aggression. All these findings suggest that post-conflict
triadic contacts in Tonkean macaques can be considered as a strategic mechanism to
calm the aggressor and reduce the risk of retaliatory aggression
