ROI names: IFGop, inferior frontal gyrus, opercular portion; MFG, middle frontal gyrus; MFGorb, middle frontal gyrus, orbital portion; PrCG, precentral gyrus; SMA, supplementary motor area; InfPar, inferior parietal cortex; SupPar, superior parietal cortex; ACC, anterior cingulate (see e.g., Fedorenko et al. 2013, for more details). All contrasts are estimated in data not used for defining the fROIs, as described in Methods. Degrees of freedom are 19. Asterisks denote effects that survive the Bonferroni correction for the number of fROIs (at 0.05/18 = 0.0027).
