ABSTRACT
Interpersonal synchrony (IPS) is a ubiquitous phenomenon in social interactions characterized by the rhythmic entrainment of movement behavior as well as neurophysiological processes. While there is evidence that IPS supports social bonding and facilitates group formation and collaboration, definitions within communication research are vague and its mechanisms remain elusive. Starting from basic definitions of synchrony in physics and biology, this chapter discusses the particularities of IPS in humans and reflects on possible explanations, presents existing research evidence for its effects, and addresses open methodological challenges.
