Accuracy rates were analyzed using a similar 2 (Prime) × 2 (Target) × 3 (Beverage) mixed factorial ANOVA.2 A significant Beverage effect, F(2, 64) = 13.81, p < .001, indicated that alcohol group participants were less accurate (M = .80) than participants in the control (M = .88), t(43) = −3.27, p < .01, and placebo groups (M = .91), t(43) = −4.58, p < .001, whose accuracy rates did not differ reliably, t(42) = 1.30, p < .20. A significant Prime × Target interaction, F(1, 64) = 28.34, p < .001, indicated that participants generally were more accurate at identifying guns and less accurate at identifying tools on black-prime compared to white-prime trials (see also Amodio et al., 2004; Amodio, Devine, & Harmon-Jones, 2008; Payne, 2001, 2005). This effect was qualified by a significant Prime × Target × Beverage interaction, F(2, 64) = 3.30, p < .05. Follow-up 2 (Prime) × 2 (Target) ANOVAs within each beverage group showed significant Prime × Target interactions in each group (ps < .05). However, inspection of the means associated with this effect
