Regional activations to anticipation of (A) dollar vs. nil, (B) cent vs. nil, and (C) dollar vs. cent in correlation with age. The contrast of dollar vs. nil and dollar vs. cent identified a large cluster of brain regions. We thus applied a more stringent threshold of voxel p<0.05 FWE corrected and summarized the individual clusters in Table 1. (D) Regional activations to anticipation of dollar vs. cent in correlation with RT difference between dollar and cent trials, with RT of no money (nil) trials as a covariate. (E) Voxels that overlap between (C) and (D). These voxels together formed the region of interest for mediation analysis.
