To confirm that the reported effects are not isolated and support the structure of the comparisons shown, we ran Friedman tests as non‐parametric omnibus tests which yielded highly significant results (alpha band, p < 0.00001 , χ 2 = 115.93 , Kendall's W = 0.68 ; gamma band p < 0.00001 , χ 2 = 120.6 , Kendall's W = 0.7 ).
