Among the major transitions in the evolution of biological complexity is the clustering of independent individuals in groups, colonies and societies. Clustering allows for individuals to cooperate – paying costs to benefit others’ fitness – and to compete – spending ‘…energies on injuring others, and on protecting against being injured’. Somewhat puzzling is that throughout nature, cooperating...
Bonds, good and differentiated relationships, among group members have fitness benefits, also bonds among non-kin males and females. Here we explore from a deductive framework in what circumstances Between Sex Bonds (BSB) can be expected in multi-male multi-female primate group. BSB are considered a way to access sources of power that are subject to leverage provided by the other sex. This...
Vocal accommodation, the process by which individuals make their vocalizations more similar to those of social partners, facilitates communication and interactions between individuals. This convergence can occur at multiple levels, however, most studies have focused on within-call structural changes and whether mammals also converge in call sequence structure remains largely unknown. We tested...
Computer vision provides powerful tools for studying primate behavior in videos recorded in the wild by enabling automatic tracking of individuals and detection of their behaviors. While much of the existing work has focused on identifying individual actions, relatively little attention has been given to detecting social interactions among nonhuman primates.
In this talk, we present a deep...
Social interactions often unfold in real time with direct face-to-face visibility. Yet, the behavioural and neuronal mechanisms of dynamic strategic interactions remain not well understood. Here, we studied macaque monkeys in a dyadic Bach-or-Stravinsky (BoS) economic decision game, which incentivizes coordination but entails an inherent conflict about which of two options to coordinate on....
Cooperation success has long been hypothesized to be causally linked with psychophysiological synchronization. For example, shared synchronous musical experiences elicit synchrony in heartbeats and influences participants’ performance in a cooperation task later. What remains unclear is how psychological synchronization emerges and the exact triggers that help or hinder synchronization. In...
Previous research shows that pigs (Sus scrofa domesticus) are sensitive to each other’s emotional states and provide targeted aid, including helping and consolation. However prosocial behavior in pigs varies greatly across individuals and experiments. We present data from two studies indicating an important role of emotional arousal in mediating prosocial behavior. In the first study, n = 74...
The ability to form stable de novo relationships in complex environments is essential for social functioning and is impaired in severe psychiatric disorders including autism. Yet, the neurobiological basis and cognitive processes enabling the formation of stable bonds in larger groups remain poorly understood, thereby limiting our ability to develop effective therapies. Here, we establish a...
