摘      要：Background:Interpersonal coordination is an essential aspect of daily life,and crucial to performance in cooperative and competitive team *** empirical research has investigated interpersonal coordination using a wide variety of analytical tools and frameworks,to date very few studies have employed multifractal techniques to study the nature of interpersonal coordination across multiple spatiotemporal *** the present study we address this ***:We investigated the dynamics of a simple dyadic interpersonal coordination task where each participant manually controlled a virtual object in relation to that of his or her *** tested whether the resulting hand-movement time series exhibits multi-scale properties and whether those properties are associated with successful ***:Using the formalism of multifractals,we show that the performance on the coordination task is strongly multi-scale,and that the multi-scale properties appear to arise from interaction-dominant ***,we find that the measure of across-scale interactions,multifractal spectrum width,predicts successful performance at the level of the ***:The results are discussed with respect to the implications of multifractals and interaction-dominance for understanding control in an interpersonal context.
