<p>. Means over participants of EEG power and within-participant standard deviation of power in theta, alpha and beta bands for alcohol (dark bars) and placebo or pre-ingestion (light bars) conditions for the three studies. These variables were not affected by alcohol in (A) Study 1 (p>.05), but were in (B) Study 2 (p<.01) and (C) Study 3 (p<.01); the four alpha and beta variables increased with alcohol in Study 3 (p’s<.05). In an exploratory analysis of Study 1, the divergence analysis selected beta and theta band power from the group of six, and weighted and combined them in a simple equation that recognized alcohol’s EEG effect. That equation was then applied to the different groups of participants in Studies 2 and 3. Error bars are standard deviation.</p
