(a) An example of the lag analysis. Here, simulated data is shown exhibiting a mutual adaptation dynamic. In the first graph the ITI of a simulated sequence is shown. Cross-correlation is performed on the ITI timeseries, giving correlation coefficients for lag −1, 0 and +1. (b) An illustration of different synchronization strategies and their corresponding lag patterns. Mutual adaptation occurs when a perception-action loop is formed between the two members of a dyad, such that they equally weigh the incoming auditory stimuli from the other member, and their own model of the task. Leading-following depends on one of the dyad members to attenuate the information coming from the other member, here illustrated by the missing connection between the blue member’s tapping and the orange member’s headphone. As such, the leader puts more confidence in their own internal model. In the case of leading-leading, as observed in our experiment, both participants exhibit leading behaviour. Here, they both discard information from the other member and rather relies on their own model.
