Grand average timecourses of total event-related theta power under alcohol and placebo recorded at Cz are shown in Figure 5. Repeated measures ANOVA was carried out on theta power estimates averaged in the 450–650 ms latency window (Table 1). The strongest theta power was observed to the imperative AN words as compared to both SW and PW, F(1,19) = 29.2, p < 0.0001. Additionally, SW elicited stronger theta than PW, F(1,19) = 15.2, p < 0.01. While alcohol intoxication decreased theta power overall, F(1,19) = 13.1, p < 0.001, it did so especially for the AN condition, F(1,19) = 7.0, p < 0.05. Theta to SW was only marginally attenuated by intoxication, F(1,19) = 3.6, p < 0.07.
