Additional statistical tests of the interactions

Comparison	ANOVA	ηG2	LMER	LMER β	BEST
Region by stim. cond. by subj. group	p = 0.009	0.04 [0.00, 0.24]	p = 0.016	−0.92 [−1.68, −0.15]	−0.58 [−1.0, −0.14]
Frontal: stim. cond. by subj. group	p = 0.003	0.13 [0.00, 0.37]	p = 0.002	1.02 [0.40, 1.64]	−0.98 [−1.6, −0.37]
Occipital: stim. cond. by subj. group	p = 0.7	0.0023 [0.00, 0.13]	p = 0.7	0.10 [−0.44, 0.64]	−0.13 [−0.71, 0.41]

Columns show the comparison being tested; p value computed in an ANOVA; ηG2 with 95% CI from the ANOVA; p value computed from model comparisons in linear mixed-effects models (LMER) after dropping the interaction of interest; median and 95% posterior distribution of the interaction β parameter estimate of the LMER model; interaction estimates and 95% CI using Bayesian estimation; stim. cond.: stimulus condition (videos of sign vs dance); subj. group: subject group (dancers vs signers).
