Humans evolved a psychological preference for interpersonal touch because it promotes social bonding and stress regulation
Multiple lines of neurobiological and psychological research indicate that interpersonal touch is an evolutionarily conserved behavior that facilitates social bonding and effective stress regulation.
The claim states that humans evolved a psychological preference for interpersonal touch because it promotes social bonding and stress regulation. Retrieved papers provide strong converging evidence: Paper 0 discusses the evolutionary role of sensorimotor cues in social cohesion, Paper 2 connects affective touch to early attachment and homeostatic regulation, Paper 3 highlights social touch as an evolutionarily conserved stress buffer, and Paper 6 explores how touch-related predictions modulate autonomic arousal. No papers refute the claim, leading to a SUPPORTED verdict.

Paper 0 highlights that face-to-face and embodied social interactions rely on sensorimotor cues like touch to foster interpersonal synchrony and trust.
