Behavioral results showing the effect of judgment manipulation.

<p>Subjective rating regarding the pleasure for four types of judgments (mean ± SEM) was modulated by the valence of judgment.</p

fMRI results showing misjudgment-specific and reward-specific brain activations.

<p>All maps are thresholded at FDR <0.05 combined with cluster level corrected, FWE <0.05. (A) Sagittal view of rACC activity (at MNI coordinates x = 6) increased in cases of right judgments compared to those with wrong judgments. (B) Coronal view of the striatum activity (at MNI coordinates y = 14) increased in cases of positive judgments compared to negative judgments. (C) Plots and regression line of correlation between rACC activations for positive misjudgment conditions (PW) and that for negative misjudgment conditions (NW) (<i>r</i> = 0.574, <i>P = </i>0.032).</p

Brain regions showing significant activity by whole brain analyses.

<p>(FDR <0.05 combined with cluster level corrected, FWE <0.05).</p><p>Notes: x, y, z indicate the MNI coordinates of the local peak of each cluster. R, the right hemisphere; L, the left hemisphere. Neither the right>wrong contrast nor the interaction (accuracy×valence) showed any significant activations.</p

The brain activation in High Cooperation minus Low Cooperation contrast.

<p>Significant activations observed in the right DLPFC (P<0.001, uncorrected for display use) (a) and left ACC (b). ACC, anterior cingulate cortex, DLPFC, dorsolateral prefrontal cortex.</p

The common brain activations in High minus Control Cooperation and Low minus Control Cooperation contrasts.

<p>Significant activations were observed in the bilateral AI, bilateral DLPFC, and OFC (P<0.001, uncorrected for display use). AI, anterior insula; DLPFC, dorsolateral prefrontal cortex; OFC, orbitofrontal cortex.</p

Results in acquisition phase.

<p>(<b>A</b>) Mean reaction times for auditory stimuli in session 1 and session 2. Bars represent standard errors. (<b>B</b>) Pleasantness ratings for auditory stimuli in pre- and post-acquisition sessions. Green, black and blue lines show auditory stimuli paired with positive, neutral and negative outcomes, respectively. Bars represent standard errors.</p
