Our results have shown that there was a significant positive correlation between ERP measures (ERP factor 1) and RT variables (TRB factor 1) as shown in Table 3. The longer the reaction time (and hence lower the impulsivity), the higher the ORP amplitude. This observation is further strengthened by our finding that there is a tendency that higher motor impulsivity is related to lower ORN and ORP amplitude. As reported, quicker reaction time is considered a core aspect of impulsivity [64], and this finding is common for many choice-reaction paradigms. Further, in our results, it can be observed that many TRB and BIS variables tend to negatively correlate with (factors of) ERP latency variables, while cognitive impulsivity, on the other hand, had a positive correlation. These findings suggest that there appears to be a potential relationship between behavioral/impulsivity and ERP measures. In the research literature, behavioral measures and the level of impulsivity have already been shown to be correlated with N2 and/or P3 components in the error-paradigms [13, 32-34] as well as in the gambling paradigms [15, 22].
