Basic Neuroimaging results. (Top) Activation in the vmPFC correlated with SV at the time of free choice in both monetary and social conditions. (Middle) Activation in the vStr correlated with PE at the time of outcome in both monetary and social free choice conditions (albeit the conjunction did not survive our omnibus threshold). (Bottom) Activation in the vmPFC correlated with R in both monetary and social free choice conditions. For illustration purposes only, all images are thresholded at P < 0.005 uncorrected with an extent threshold of 15 voxels, except for the conjunction of PE which is P < 0.005 with an extent threshold of five voxels (see Tables 1–3 for details).
