In the placebo group, the FRN was negatively correlated with P300 amplitudes. However, ERP responses to feedback were unrelated to risk-taking behavior during the BART. Furthermore, significant correlations were found between BART parameters and personality measures: a negative correlation was found between BAS total score and the mean number of pumps in block 1. Moreover, a strong positive correlation was found between the total impulsivity score and FRN amplitude.
