Main effect of outcome. (A) A significant main effect of outcome emerged during a 2 (role) × 3 (competitor) × 2 (outcome) whole-brain repeated measures ANOVA in bilateral ventral striatum. (B) BOLD responses in the left ventral striatum (x, y, z, = −10, 7, 0) demonstrated enhanced value signals to positive compared with negative outcomes across all competitor conditions. Activation map was set to an initial uncorrected height threshold of P < 0.001 and subsequently, whole-brain corrected at the cluster level to a threshold of P < 0.05.
