Data from: Audience affects decision-making in a marmoset communication network

An audience can have a profound effect on the dynamics of communicative interactions. As a result, nonhuman primates often adjust their social decision-making strategies depending on the audience composition at a given time. Here we sought to test how the unique vocal behavior of multiple audience members affected decisions to communicate. To address this issue, we developed a novel experimental paradigm in which common marmosets directly interacted with multiple ‘Virtual Monkeys’ (VMs), each of whom represented an individual marmoset with distinct vocal behavior. This active social signaling paradigm provided subjects an opportunity to interact with and learn about the behavior of each VM in the network and apply this knowledge in subsequent communicative decisions. We found that subjects’ propensity to interact with particular VMs was determined by the behavior of each VM in the audience and suggests that marmoset social decision-making strategies are highly adaptive to nuances of the immediate communication network.
