Table S1 Activations identified via a whole-brain paired samples t-test comparing the Cyberball and Cybershape contrasts (social exclusion > fair play and rule violation > fair play). Between game comparison of differential activation in Cyberball and Cybershape. A paired samples t-test compared social exclusion – fair play in Cyberball to rule violation – fair play in Cybershape. Talairach coordinates refer to the voxel with the maximum signal change in each region of interest. Statistics reported are for the average of all voxels in the region of significance (avg). Region sizes are reported in structural voxels (1 × 1 × 1 mm). Abbreviations: dorsomedial prefrontal cortex (dmPFC), dorsolateral prefrontal cortex (dlPFC), middle occipital cortex (MOC), posterior cingulate cortex (PCC), middle temporal gyrus (MTG), ventrolateral prefrontal cortex (vlPFC), inferior parietal lobule (IPL), inferior occipital gyrus (IOG), superior temporal sulcus (STS).

Figure S1 Average beta values for a structurally defined region of ventral anterior cingulate cortex from each experimental condition in Cyberball and Cybershape. ‘Control’ conditions refer to fair play in Cyberball and Cybershape. ‘Experimental’ conditions refer to social exclusion and rule violation in Cyberball and Cybershape, respectively. The subtraction of experimental – control conditions was done for each participant individually, and then difference values were averaged for each game. Bars represent standard error. Activation in ventral anterior cingulate cortex was significantly greater than zero in fair play, social exclusion, and in the contrast of social exclusion – fair play (< .05), but not in any other conditions.
