Oxytocin modulates human communication by enhancing cognitive exploration.

Area of Science:

• Neuroscience
• Cognitive Science
• Social Psychology

Background:

• Oxytocin, a neuropeptide, is known to influence material resource sharing.
• Human communication involves signal selection for meaning disambiguation and audience design.
• The impact of oxytocin on knowledge sharing remains largely unexplored.

Purpose of the Study:

• To investigate the effect of oxytocin on knowledge sharing through non-verbal communication.
• To examine oxytocin's influence on referential quality and audience design in communication.
• To understand how oxytocin modulates cognitive exploration in communicative behaviors.

Main Methods:

• A randomized, double-blind, placebo-controlled experiment with 55 male participants.
• Intranasal administration of oxytocin.
• Participants produced novel non-verbal signals towards adult and child addressees in a live interactive setting.

Main Results:

• Oxytocin administration led to the generation of signals with higher referential quality.
• Participants receiving oxytocin rapidly adjusted communicative signals based on addressee understanding.
• Oxytocin promoted more pervasive exploration of communicative behaviors and addressee models.

Conclusions:

• Oxytocin influences knowledge sharing by enhancing signal clarity and audience-specific adjustments.
• The findings suggest oxytocin promotes cognitive exploration, impacting intention conveyance and understanding of others.
• Beyond prosocial drives, oxytocin modulates cognitive processes crucial for effective knowledge sharing.
