A repeated measures analysis of variance revealed a Condition main effect, F(1, 85) = 34.05, p < .001, ηp2 = .29, 1-β = .99, and a Region main effect, F(4, 82) = 155.39, p < .001, ηp2 = .88, 1-β > .99. These effects were qualified by a Condition × Region interaction, F(4, 82) = 12.13, p < .001, ηp2 = .37, 1-β > .99. Post Hoc tests consisted of paired samples t-test of the condition difference effect between regions. We tested these with a Bonferroni correction (.05/10 comparisons = .005 corrected threshold). Table 3 presents the condition means, standard errors, condition differences by Brodmann area and t-tests. Overall, the condition difference at BA 25, subgenual ACC was larger than, and significantly different from, the condition changes at all the other regions (all p’s < .001, Table 3 right panel). Thus, the Condition × Region interaction was largely driven by this effect. As a follow-up, related post hoc analyses of the condition effects revealed significant differences at BA 11 (orbitofrontal cortex), BA 24 (Ventral ACC) and BA 25 (subgenual ACC)
