		HHb	Main effect of block type Time × block type interaction	F (1, 56) = 8.041, p = .006, ηp2 = 0.126 F (3.923, 219.713) = 5.170, p = .001, ηp2 = 0.085

Note. All 6 channels showed a significant main effect of time (p < .05), see SM 7a for statistics. None of the effects presented in this table survived correction for the FDR (84 comparisons).
