Table 3.
Correlation between ERP factors and Impulsivity factors are shown. Correlation coefficient (r, top number within the cell) and the level of significance (p, bottom number within the cell) before correcting for multiple testing. The significant correlations (highlighted in bold font) that remained significant after Bonferroni correction has been marked with an asterisk and the correlations that lost significance have been indicated with the symbol ‘β’. The minus sign (−) indicates a negative correlation.
