Data were analyzed using SPSS version 12.0. Of the 32 channels, data from fifteen electrodes were selected and grouped into three regions, viz. frontal (F7, F3, Fz, F4, F8), temporo-central (T7, C3, Cz, C4, T8), and parietal (P7, P3, Pz, P4, P8). Subject and task related variables such as age, education, reaction time and details of drinking were analyzed for group differences using t-tests. As a primary analysis, repeated measures ANOVAs were used separately for amplitude and latency, with group as the between-subjects variable. Semantic condition (primed and unprimed) and scalp region (frontal, central, and parietal) were entered as the within-subjects factors. Secondary analysis included examining group differences using separate repeated measures ANOVAs for amplitude and latency measures for both primed and unprimed conditions. Scalp region and electrode position were entered as within-subjects factors. Greenhouse-Geisser correction was employed when required. Unless otherwise mentioned, the results were non-significant.
