Feedback prediction errors for immediate and delayed feedback conditions. Model-derived prediction errors were estimated separately for each delay. Viewing these direct contrasts at a threshold of p < 0.05 restricted to the hippocampus and the striatum revealed a greater correlation between prediction errors and BOLD activity for Delayed than Immediate feedback in the hippocampus. This effect was also apparent at a slightly more conservative threshold of p < 0.005 (see inset). In contrast to the hippocampus [−30 −12 −18], the dorsal striatum [15 15 15] showed a greater correlation with prediction errors for immediate than for delayed feedback (p < 0.05).
