Correlation analyses revealed significant associations between demographic / alcohol use variables and N2 and P3 measures. For NAC, P3b and N2a amplitudes decreased with increasing age (r = −0.300, p = 0.017; and r = −0.301, p = 0.019). For TNAD, increasing age was associated with longer P3b, N2a, and P3a latencies (r = 0.34, 0.32, and 0.31, all p’s < 0.01), and higher family drinking density was associated with longer P3b latencies (r =0.24, p = 0.043). Across all subjects, P3b latency, but not P3a nor N2b latency, was negatively correlated with the attention domain neuropsychological test score (r = −0.17, p = 0.05). Other than these associations, there were no significant or trend (p< 0.10) associations.
