Interpersonal Physiological Synchrony During Dyadic Joint Action Is Increased by Task Novelty and Reduced by Social Anxiety.

ABSTRACT: Interpersonal physiological synchrony refers to the temporal coordination of autonomic states during social encounters. Previous studies indicate that physiological synchrony may arise during nonverbal interactions. Nevertheless, the role played by contextual and individual factors in determining its emergence is understudied. In this work, we examined heart rate synchrony during a cooperative joint action task, exploring how task constraints, novelty, and behavioral synchrony influence physiological alignment. To achieve this, we periodically modulated task demands by alternating between peer-to-peer and leader-follower dynamics, as well as between complementary and imitative movements, and their combinations. Additionally, we assessed the role of individual differences by examining the i
