Figure 2.
A region of dorsal MPFC (depicted at x = 4) was defined from an independent sample of participants who alternately read stories about mental states and physical representations. The contrast of mental > physical trials revealed an extensive region of dorsal MPFC. The response in these voxels when judging other people correlated significantly with money that participants allocated to others across both studies. The scatterplot displays the correlation between response of this dorsal MPFC region (in standardized arbitrary units; x-axis) and generosity (standardized proportion of money donated; y-axis), r(29) = 0.46, p < 0.01 (Study 1: r(14) = 0.53, p < 0.05; Study 2: r(13) = 0.34, p = 0.22).
