Human and nonhuman animals engage in complex joint actions, characterized by interactions where individuals coordinate their behaviours in space and t…

Recognizing vocal behaviours intended to benefit others is a crucial yet understudied social skill. Primates with rich vocal repertoires and complex societies are excellent models to track the evoluti...

Behavioral contagion is widespread in primates, with yawn contagion (YC) being a well-known example. Often associated with ingroup dynamics and synchronization, the possible functions and evolutionar...

Behavioral Ecology and Sociobiology - During risky interactions like social play, motor resonance phenomena such as facial mimicry can be highly adaptive. Here, we studied Rapid Facial Mimicry...

Scientific Reports - The sound of yawns makes geladas yawn

Journal of Ethology - Animal internal states can be expressed via social behaviors that are known to shape group dynamics (i.e., allogrooming, social play, agonistic encounters) and that can be...
