Effects of ethanol on foreground contextual fear conditioning at testing 1 week after training. Animals were initially tested at 4 or 24 hours post-training. RT indicates the 1 week retest; no drug was administered at retest. Groups administered 0.25 g/kg ethanol before training froze to the context (context RT) significantly more than controls, whereas groups administered 1.0 g/kg ethanol froze significantly less than controls. The groups administered 0.5 g/kg ethanol were not significantly different from controls. Post hoc tests revealed no significant differences in freezing to an altered context (pre-RT) or to a tone [conditioned stimulus (CS RT)] (mean ± SEM; *indicates significant difference from controls, p < 0.05).
