The correlations between the behavioral factors/variables and the ERP factors are shown in Table 3. After correcting for multiple testing, the only significance (p < 0.05) observed was a positive correlation between the first factor of the ERP (i.e. primarily the amplitudes of ORN and ORP components) and the first factor of TRB measures (i.e. the reaction time variables). Four originally significant correlations lost significance due to Bonferroni corrections: 1) negative correlation between ERP factor 3 (i.e. latencies of ORP during −50 condition and TRB factor 1; 2) negative correlation between ERP factor 1 and motor impulsivity of BIS, 3) negative correlation between ERP factor 2 and Motor impulsivity; and 4) positive correlation between ERP factor 3 and cognitive impulsivity of BIS.
