Effects of ethanol on background contextual and cued fear at testing 1 week after training. Animals were initially tested at either 4 or 24 hours post-training. Groups administered 0.25 g/kg ethanol before training froze to the context significantly more than controls, whereas groups administered 1.0 g/kg ethanol froze significantly less than controls. Groups administered 1.0 g/kg ethanol were also significantly different from controls in freezing to a cue (conditioned stimulus; pre-CS RT). There were no significant differences in freezing to an altered context (pre-RT) (mean ± SEM; *indicates significant difference from controls, p < 0.05).
