Results of statistical analyses for Alpha power.


ALPHA POWER
Multiple comparisons with FDR correction 20 × 4 × 2 mixed ANOVA 4X4X3X2 mixed ANOVA
First set of meditative practices, performed by all practitioners (N = 16) M2: Decrease in F7 (p = .07) No sig effect of Practice, F < 1, p = .78
Sig effect of Electrode,F (19,266) = 5.95, p = .00, ηp2 = .30, with higher power in Cz and POz than in T5 (ps < .05)
No sig effect of Tummo Expertise, F < 1, p = .49, but Practice X Tummo is marg, F(3,42) = 2.81, p = .05, ηp2 = .16
No sig effect of Meditation Experience, F < 1, p = .85
Sig effect of Region, F(3, 42) = 3.66, p = .02, ηp2 = .21 with Alpha power in the frontal region being lower than in the central region (p < .02)
Sig effect of Lateralization, F(2,30) = 5.21, p = .01, ηp2 = .27; midline Alpha power is higher than left and right (p < .02)
Multiple comparisons with FDR correction 20X5 repeated measures ANOVA 5 × 4 × 3 repeated measures ANOVA
All practices performed by Tummo experts (N = 10) M1: Increase in P3 (p < .05)
Yidam: Increase in P4 (p = .07)
M2: Decreases in F7, P3, T3, Pz, (p < .05), and in Fp1, F4 (p < .06)
Tummo: Increases in F3, F7, Fp1, T3, T6, P3, P4, Pz, POz (p < .05), and in F4, Cz (p < .06)
Sig effect of Practice, F(4,36) = 6.89, p = .000, ηp2 = .43; sig decrease during M2,F(1.9) = 6.54, p = .03, ηp2 = .42 sig increase during Tummo,F(1.9) = 30.80, p = .000, ηp2 = .77
Sig effect of Electrode, F(19,171) = 10.75, p = .000, ηp2 = .38 with power higher in C4 and Cz than in F7, T3, T4 (ps < .05).
Sig effect of Region, F(3,27) = 9.09, p = .00, ηp2 = .50, with power in the frontal region being lower than in the central (p < .03)
Sig effect of Lateralization, F(2,18) = 8.33, p = .003, ηp2 = .48, with midline power higher than left (p = .004)
Sig Region X Lateralization, F(6,54) = 4.09, p = .002, ηp2 = .31, with midline power being the highest in anterior regions (p < .05) and higher than left in posterior regions
