Abstract
In a go/no-go situation in a runway, rats employed the memory of a single food reinforcement as an S+ cue and the memory of two consecutive reinforcements as an S− cue. To do this, however, one group had to classify two qualitatively different reinforcers as different (Group Different, Experiment 1), whereas another group had to classify the same two reinforcers as similar or alike (Group Same, Experiment 2).
