Experiment 3.

<p>Animals learned to associate incentive Pavlovian cues with access to sweetened condensed milk as reward. A. Latency to drink. B. Drinking time. C. Fluid intake. D. Total 50-kHz calls. E. Tone cue-induced 50-kHz calls. Control vs. reward: * <i>p</i><.05, ** <i>p</i><.01. FD vs. FAL: + <i>p</i><.05, ++ <i>p</i><.01. FD vs. FAL in both groups: x all <i>p</i><.05. Day 1 differed from days 3 to 7 in reward rats: § <i>p</i><.05. Day 1 to 5 differed from day 7 in both groups: & <i>p</i><.05. Day 8 differed from days 7, 9, and 10 in reward rats: # all <i>p</i><.05. Data are expressed as mean+SEM (control = 12, reward = 12).
