Percent of time freezing is significantly reduced by acute exposure to 0.25% alcohol in a stimulus presentation independent manner. Mean ± S.E.M. are shown. Note that during the pre-stimulus period, the first interval, no stimulus was shown, during the stimulus period a moving black bird silhouette was presented multiple times, and during the post-stimulus period again no stimulus was presented. The shading of the bars corresponds to the alcohol dose used with darker shades indicating higher concentrations (see legends). For details of the results of statistical analyses see Results.
