A Kuramoto model of self-other integration across interpersonal synchronization strategies
Fig 1
In A) a joint finger tapping paradigm is illustrated. Two persons (dyad members) tap an isochronous rhythm together. Their auditory feedback can be manipulated so that the dyad is bidirectionally coupled, i.e. that dyad member 1 hears dyad member 2 and vice versa, here illustrated in the top right. In the two bottom illustrations we see unidirectional coupling, wherein the information between dyad members only goes one way, for instance so that dyad member 1 only hears dyad member 2, and dyad member 2 hears only themselves. B) Time series representing the intertap interval, a measure of the time between successive taps, of each dyad member. Colours indicate dyad member. When these time series are cross-correlated at lag -1, lag 0, and lag +1, a pattern such as illustrated in C) emerges. Here, the pattern would indicate a mutual adaptation synchronization strategy.
