Experimental task. A, Example of the structure of a single session. Each experiment consisted of four sessions lasting 5 min each. A single session includes five “RESPOND” blocks, in which the subject made button presses, and five “REST” blocks. At the end of each session, subjects rated how causal their button presses were in earning money on a scale from 0 to 100. B, Example of the event schedule of the RESPOND block. When the subject pressed the button, the stimulus on the screen turned yellow for 50 ms. Reward (25 cents) was delivered at the first button press after the 10th response (on average) on the VR10 schedule.

A–C, Voxels showing significant correlations with the global objective correlation in the mPFC [(x, y, z) = (−6, 52, −10); p < 0.05, SVC with a 5 mm sphere centered at (6, 57, −6) (Hampton et al., 2006); A], mOFC [(x, y, z) = (−2, 30, −20); p < 0.05, SVC with a 5 mm sphere centered at (−3, 36, −24) (Valentin et al., 2007); B], and dorsomedial striatum [anterior caudate nucleus; (x, y, z) = (6, 10, 20); p < 0.001, uncorrected; C]. Bar plots show parameter estimated at each peak voxel sorted by global objective correlation. D, Plot of averaged BOLD signal extracted from mPFC, against the local objective correlation and regression slope (R2 = 0.72; p = 0.0021). E, Plot of averaged BOLD signal extracted from mPFC against reinforcement rate and regression slope (R2 = 0.053; p = 0.62). Error bars = 1 SEM.

Voxels showing significant activation in the high-causality condition in the mPFC [(x, y, z) = (−10, 50, −10); p < 0.001, uncorrected], and parameter estimates sorted at the peak voxel of the mPFC by causality value. Error bars = 1 SEM.
