Figure 2. BOLD activity is correlated with continuous measures of marginality.

(A) The group alignment metric. A participant's group alignment metric was defined as the percentage of other group members who made the same choice during the previous trial. Information regarding the buttons pressed by each group member in the previous trial was revealed at the onset of the current trial. (B) The reward rank metric. A participant's reward rank metric was defined as the ordinal value of the participant's earnings relative to those of the other participants on each trial, with higher values indicating greater relative rewards. Information regarding the earnings of each group member in the previous trial was revealed at the onset of the current trial. (C) Effect of group alignment in the Choices condition. In the Choices condition, activity in the insula, thalamus, DLPFC, dACC, and parietal cortex was inversely proportional to the participant's group alignment (p<.05 corrected; see Table 1). (D) Effect of group alignment in the Both condition. In the Both condition, activity in the insula, DLPFC, dACC, and parietal cortex was inversely proportional to the participant's group alignment (p<.05 corrected; see Table 2).
