Table 4 shows the correlations between risk-taking behavior during the BART (i.e., the mean number of pumps), feedback-related ERPs, and self-reported personality measures. As can be seen, the amplitude of the FRN in the alcohol group was not correlated with the feedback-related P300 amplitude, which further supports the independence of the two components during feedback processing. In the alcohol group, strong correlations were found between the ERPs and risk-taking behavior. Remarkably, FRN to negative feedback was positively correlated with the mean number of pumps, whereas P300 amplitudes were negatively correlated with risk-taking behavior. These results indicate that in the alcohol group, hyposensitivity for negative feedback as measured with P300, but not FRN, is associated with increased risk-taking. Furthermore, none of the correlations between BART parameters and personality measures were significant, which provide evidence to suggest that a direct psychopharmacological effect of alcohol, rather than individual factors, play an important role in moderating risky decision-making.
