Reward downshift in the toad
The effect of reward downshift on runway performance using water as reward is studied in toads. Toads do not show negative contrast effect but a decline in performance to the same level as the small reward unshifted controls when downshifted after 50 and 80 preshift trials. These results suggest tha...

| Sumario: | The effect of reward downshift on runway performance using water as reward is studied in toads.

These results suggest that the role of reward in toads differs from that in rats. © 1981 Academic Press, Inc. |
