Behavior and ERP results from the BART with real and hypothetical monetary rewards. Average pumps following loss and win (gain) feedback for results of different scales (a), and the mean FRN amplitudes at Cz for four kinds of results in the 210–270 ms time window post-onset of feedback (b). Error bars represent standard error (SE). Loss_R, loss with real money; Loss_HY, loss with hypothetical money; Gain_R, gain with real money; Gain_HY, gain with hypothetical money. **Significant difference of p < 0.01.
