The relationship between P3 amplitude and impulsivity has been summarized in Table 4. Gain-related P3 amplitudes had significant negative correlations with BIS scores, while there was no such relationship observed for the loss condition. The significant correlations during the gain condition were: FZ with non-planning, attentional, and total scores, CZ with attentional and total scores, and both PZ and OZ with attentional score. Although these correlations were statistically significant, the values of the coefficients (r) are much smaller, and therefore these results should be interpreted with caution. Correlations within the groups (risk group, gender and age group) were not significant.
