Note: RS, raw score; RT, reaction time; INACC, percent incorrect; IPS, intraparietal sulcus; IFG, inferior frontal gyrus; SFG, superior frontal gyrus; ROI, region of interest.
Partial correlations controlling for age are reported above the diagonal and bivariate correlations are reported below the diagonal.
