p = .30) or the alcohol group, for whom the N2 was smaller 2 trials following errors (M = 0.30 µV) than 2 trials following correct responses (M = −0.24 µV), t[1957] = −3.15, p < .01. Critically, the Group × 2-back accuracy × Current trial type interaction was not significant (F < 1). As indicated in the bottom portion of Table 2 (and see Figure 4), for participants in all beverage groups incompatible arrays elicited larger N2s than compatible arrays two trials following correct responses and errors.
