Recurrence Quantification as an Analysis of Temporal Coordination with Complex Signals

Ample past research demonstrates that human rhythmic behavior and 1 rhythmic coordination reveal complex dynamics. More recently, researchers have 2 begun to examine the dynamics of coordination with complex, fractal signals. Here, 3 we present preliminary research investigating how recurrence quantification tech4 niques might be applied to study temporal coordination with complex signals. 5 Participants attempted to synchronize their rhythmic finger tapping behavior with 6 metronomes with varying fractal scaling properties. The results demonstrated that 7 coordination, as assessed by recurrence analyses, differed with the fractal scaling of 8 the metronome stimulus. Overall, these results suggest that recurrence analyses may 9 aid in understanding temporal coordination between complex systems. 10
