The mean preferred coupling phase, calculated per session over channel combinations and subsequently averaged over sessions (N = 10), differs between trial types. The distributions of pairwise comparisons of coupling phase between trial types at the channel combination level (with an expected difference in phase angle of 0°) were tested using a circular paired t test.
↵Mean phases marked with a differ from b; p < 0.05. Rayleigh's Z values (larger Z values indicate phase distributions deviating more from a uniform distribution) marked with cdiffer from dacross sessions; p < 0.05. The concentration of phase distributions (concentration parameter κ from the fit to a von Mises distribution) also differed between trial types. z-scored κ values for groups marked with e are larger than for the group marked f;
