Perceptions of synchrony: Different strokes for different folks?

The spectacle of synchronous activity is both engaging and, for the social perceiver, informative. Judgments of the quality of social interactions covary with key characteristics of coordination dynamics (ie relative phase). Here we examined the converse relationship are perceptions of synchrony shaped by social factors? Participants judged dyads consisting of individuals with dissimilar skin tones to be less coordinated than those with similar complexions, despite the amount of coordination being objectively equivalent. The methodological and practical implications of these findings are discussed.
