The rhythm of joint action: Synchrony promotes cooperative ability

Although evidence has suggested that coordinated action enhances rapport and fosters cooperation, the possibility that it might also influence the ability to pursue joint goals has yet to be demonstrated. We show that rocking in synchrony enhanced individuals’ perceptual sensitivity to the motion of other entities and thereby increased their success in a subsequent joint-action task that required the ability to dynamically detect and respond appropriately to a partner’s movements. These findings support the view that in addition to fostering social cohesion, synchrony hones the abilities that allow individuals to functionally direct their cooperative motives.
