Terminal Level

Four groups of 8 albino rats each were magazine trained under high or low drive, barpress trained with the same 32% sucrose incentive or water (designed to produce “frustration”), and tested in extinction with an inoperative magazine. The results confirmed earlier ones obtained with an inaccessible-food training operation in that the major factor determining extinction performance was terminal level of reinforced responding in training.
