Figure 4.

Long-latency ERPs. Results in the 550–700 ms time window are shown. A, Topographical figures mapping the differences between stimuli that were more frequently related to high-value outcome (S^high) and to low-value outcome (S^low) for all conditions. Relative scale (minimum/maximum values): −1/+1 μV. B, Mean evoked activity locked to stimulus onset (100 ms baseline also shown) for the S^high and S^low at relevant electrode CPz. Data for the two devalued conditions, Dev O^high and Dev O^low, are shown. Black lines represent the S^high minus S^low difference waveforms for each devaluation condition. Shaded areas represent SEM of these differences.
