Conversations are dynamic systems of coordinated behavior. Utterances lengthen and shorten, emotions converge and diverge, topics stabilize and vary. Yet the temporal structure of these changes remains uncharacterized. We analyzed 1,656 extended conversations between strangers, using data across linguistic, facial, and acoustic communication channels. Our preregistered analyses tested the temporal trajectories of 27 conversational measures (e.g., utterance length, emotional similarity, topic per
