How Moving Together Brings Us Together: When Coordinated Rhythmic Movement Affects Cooperation.

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Behavioral Economics

Background:

• Rhythmic coordination with social partners is known to enhance cooperation.
• The precise mechanisms and conditions underlying this effect remain unclear.

Purpose of the Study:

• To investigate the conditions under which intentional rhythmic coordination influences pro-social behavior.
• To differentiate between synchrony and coordination, direct versus mediated effects, and threshold versus graded effects.

Main Methods:

• An experiment and two follow-up studies were conducted.
• Participants engaged in intentional rhythmic movement tasks in a social context.
• Cooperation levels were measured following the coordination tasks.

Main Results:

• Coordination, not merely in-phase synchrony, positively impacts cooperation when the social context is perceived.
• The pro-social effects of intentional coordination are direct, not mediated by other variables.
• The degree or quality of coordination did not correlate with the extent of cooperation.

Conclusions:

• The mere act of inter-personal rhythmic coordination within a social context is sufficient to elicit pro-social effects.
• Future research should utilize controlled experimental paradigms to further elucidate the mechanisms of coordination's impact on pro-social behaviors.
