Taste reactivity responses to sucrose delivery in the final devaluation session of Experiment 2. Rats in the Devalue condition received lithium chloride injections immediately after each session whereas rats in the Maintain condition received those injections 6–8 hr later. Negative responses included licks with narrowed tongue with minimal extension, gapes, and face-washing. Positive responses shown here included only licks with a broadened and protruding tongue. Short licks involved an intermediate (normal) tongue breadth and extension. See Behavioral analysis (Experiment 2) for details.
