“…Multifractal analysis has been applied to a large number of problems, including clustering of galaxies in astrophysics, 22 rainfall in meteorology, 23 the spatial and temporal distributions of earthquakes in seismology, 24 and aggregation in single-celled organisms. 25 In the study of human behavior, multifractals have recently been used to investigate the role of movement fluctuations in haptic perception, 26 the dynamics underlying executive control, 27 and changes in the center of pressure supporting posture.…”

BackgroundInterpersonal coordination is an essential aspect of daily life, and crucial to performance in cooperative and competitive team sports. While 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 scales. In the present study we address this gap.MethodsWe 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 partner. We tested whether the resulting hand-movement time series exhibits multi-scale properties and whether those properties are associated with successful performance.ResultsUsing 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 dynamics. Further, we find that the measure of across-scale interactions, multifractal spectrum width, predicts successful performance at the level of the dyad.ConclusionThe results are discussed with respect to the implications of multifractals and interaction-dominance for understanding control in an interpersonal context.
