Database S1 - Spontaneous Group Synchronization of Movements and Respiratory Rhythms

The database contains the coherence data for each pair of participants, in each group and in each experimental condition. Coherence is computed using the GPDC method (Baccala et al., 2007), on the movement, respiratory and cardiac signals. The analyses were focused on the following three frequency bands: “Low frequencies” (LF): 0.035–0.15 Hz; “High frequencies” (HF): 0.15–0.4 Hz; “Very high frequencies” (VHF): 0.4–2 Hz. Condition: 1 = Initial resting baseline1; 2 = Final resting baseline; 3 = Spontaneous movement; 4 = Metronome-associated movement; 5 = Music-associated movement. Group: 0 = Individual measurement group; 1 = Collective measurement group. Experiment: 1 = First set of groups; 2 = Second set of groups; 3 = Third set of groups. Each set of groups comprises n = 10 participants for the collective measurement and n = 10 participants for the individual measurement. Day: 1 = First day; 2 = Second day. Order: 1 = Condition performed in first position; 2 = Condition performed in second position; 3 = Condition performed in third position; 4 = Condition performed in fourth position; 5 = Condition performed in fifth position.
