a. Task design for the Incentive Processing Task. During a 1.5 s cue, participants guess whether a hidden number is greater than or less than five, after which feedback images are shown for 1 s. The timeline of events is illustrated above, while the three possible response feedback stimuli are illustrated below. b. Z-statistic maps thresholded using Gaussian random field theory (cluster-defining threshold, z > 2.3; cluster extent threshold, p < 0.01). Warm colors indicate significant clusters for the reward > loss contrast while cool colors indicate significant clusters for the loss > reward contrast. Coordinates of slices are in MNI space. Color bars indicate Z-statistics.
