Figure 5. Experiment 5.

Animals learned to associate incentive Pavlovian cues with access to daily feeding as reward. A. Latency to eat. B. Eating time. C. Total 50-kHz calls. D. Tone cue-induced 50-kHz calls. The dashed line indicated that a maximal latency time was set at 90 s. Control vs. reward: * p<.05, ** p<.01. Days 1 and 3 differed from days 5 and 7 in reward rats: § p<.05. Data are expressed as mean+SEM (control = 10, reward = 10).
