Further, it is of interest to study aspects of impulsivity in the context of behavioral and ERP measures in a gambling paradigm, as it has already been shown in the error-related paradigms that the amplitude of the negative (Ne) and/or positive (Pe) component was sensitive to the level of impulsivity [13, 32-34]. Using a gambling task, a few studies have examined impulsivity related measures. For example, Gehring & Willoughby [15] showed the correspondence between risk-taking behavior and outcome processing in their finding on ORN (MFN) that the choices made after losses were riskier and were associated with greater loss-related activity than choices made after gains. Similarly, Yeung & Sanfey [22] reported that individual differences in the amplitude of the ORN correlated with individual differences in risk-taking behavior observed after monetary losses, whereas individual differences in ORP amplitude were related to behavioral adjustments observed in response to alternative or unchosen outcomes.
