Additionally, we further measured the rise in N2pc amplitude and the rise in CDA amplitude from one item to two items and found that there was also a highly significant correlation between the rise in the N2pc amplitude and the rise in CDA amplitude for both adults with ADHD (r = 0. 532, p = 0. 003, two-tailed) and controls (r = 0. 487, p = 0. 006, two-tailed).
