Preexposure to small taste array during preexposure sessions enhances later learning to a novel taste. A one-way ANOVA showed that rats preexposed to W, N, and C across three preexposure sessions (gray bar) significantly enhanced learning (i.e., decreased test day sucrose consumption). Additional analysis demonstrated that both groups (W, N, C) and (W-LiCl) showed significantly enhanced learning than animals given a sham US (W-Saline; stripped bar). X-axis represents aversion indices for each animal (CSTestConsumed mL/CSConditioningConsumed mL). Error bars represent SEM. (*) P < 0.05.
