Mean (±SEM) percent time freezing during a 5min test of conditioned fear following pre-preexposure drug infusion (Experiment 2). Comparisons reflect an ANOVA for group (Alt- Pre PBS, Alt-Pre Scop, Pre PBS and Pre Scop) with planned comparisons. Scopolamine administered prior to context preexposure significantly impaired CPFE performance on the testing day. Asterisks indicate significance relative to Pre PBS group. Ampersand indicates significance within exposure condition. && = p < .01; * = p < .05; ** = p < .01; *** = p < .001.
