Who syncs? Social motives and interpersonal coordination

Interpersonal synchrony provides an important foundation for social interaction, as periods of temporal coordination lead to enhanced sociality. Moreover, synchronous actions are governed by lawful physical principles of coordination dynamics, suggesting some degree of inevitability. However, both anecdotal and laboratory evidence indicates that not all individuals synchronize. Here we explored whether differences in social motives (i.e., social value orientation) influence the propensity to coordinate with others. The results revealed that individuals with a pro-social orientation spontaneously coordinated with a confederate to a greater extent than thosewith a pro-self orientation, regardless of whether such orientations were assessed as dispositional characteristics
(Study 1) or were the result of a priming manipulation (Study 2). These findings have important implications for both coordination dynamics and prominent accounts of social exchange.
