A preliminary 5 (Coronal location) × 3 (Lateral location) ANOVA revealed a Coronal × Lateral interaction, F(8, 480) = 13.13, p < .0001, indicating that the Pe was largest at midline electrodes, particularly the midline central site (Cz). Thus, data measured at Cz were submitted to a 2 (Prime) × 2 (Target) × 3 (Beverage group) mixed ANOVA. This analysis showed a significant effect of Beverage group, F(2, 60) = 4.14, p < .05. Planned contrasts indicated that the Pe was smaller in the alcohol group (M = 5.07 μV) than in the control group (M = 8.53 μV), t(42) = −2.75, p < .05, and the placebo group (M = 7.77 μV), t(39) = −2.07, p < .05, whose means did not differ reliably (t < 1). No other effects of interest were significant in this analysis.
