Subjective estimates of postreward buffer for all subjects. (A) Subjective estimate of postreward delay, as estimated by Eq. 1, for all three subjects combined. Subjects’ estimates of postreward buffer rose with actual value but was systematically lower than the actual value. (B) Ratio of subjects’ estimate of postreward delay to actual postreward delay, average for all three subjects. Ratio was roughly constant. Average value (0.24) is shown with horizontal line.
