CI > GO = subtraction of go correct from correct inhibition conditions; II > GO = subtraction of go correct from incorrect inhibition conditions; II > CI = subtraction of correct inhibition from incorrect inhibition conditions.

# = numbers correspond to fROI regions in Figs. 3 and 4.

ACC = anterior cingulate cortex; IFG = inferior frontal gyrus; MTG = middle temporal gyrus; SMA = supplementary motor area; SMG = supramarginal gyrus; STG = superior temporal gyrus; BA = Brodmann Area; G – gyrus; R = right; L = left; B = bilateral.

${\eta }_p^2$ = partial eta-squared, a measure of effect size.

^*Significant (p < .5) partial correlations between CAP score and MR signal intensity, with age as a covariate.
