Abstract

The human studies in perception and action in social context revealed that social interaction facilitated behavioral synchronization. To understand brain mechanisms for the synchronization in details, studies in animal model are required. However, little is known about the behavioral synchronization in animals. Here we examined an unintentionally synchronized behavior in monkeys. The unintentional synchronization was quantified by changes in button-pressing behavior while two monkeys were seated facing each other. Different experimental conditions were applied to explore interferences of visual information on the speed and the timing of the button-pressing. The changes in behavior were observed when the subject was paired with another monkey, suggesting that social bonds play an important role in synchronization through visuo-motor or auditory-motor coupling to other’s behaviors.
