Appetitive conditioning and discriminatory learning in toads
The consummatory response of the water-uptake behavior in toads was used as reinforcer in two experimental procedures: (1) operant conditioning in an alleyway and its extinction, and (2) discriminative learning and its reversal.

| Sumario: | The consummatory response of the water-uptake behavior in toads was used as reinforcer in two experimental procedures: (1) operant conditioning in an alleyway and its extinction, and (2) discriminative learning and its reversal. In Experiment 1 toads dehydrated to 78% of their initial weight were trained in a runway using water as reinforcement. Running time was reduced from 62.56 sec on the 1st trial to 26.23 sec on the 35th trial. Extinction was obtained in 10 trials. In Experiment 2 toads dehydrated to the same degree were trained in a Y-maze with water reinforcement. Animals reached the learning criterion in 30 trials during acquisition and in 50 trials during reversal. These results show the capability of toads to learn when a biologically relevant motivation is used. © 1980 Academic Press, Inc. |
