The shape of lipsmacking: socio-emotional regulation in bearded capuchin monkeys (Sapajus libidinosus).

ABSTRACT: Capuchin monkeys have rich social relationships and from very young ages they participate in complex interactions with members of their group. Lipsmacking behaviour, which involves at least two individuals in socially mediated interactions, may tell about processes that maintain, accentuate or attenuate emotional exchanges in monkeys.
