Question:

Two groups of rats are trained to press a lever for food on a constant reinforcement schedule. One group receives 1 piece of food; the other, 3 pieces. In extinction,

a. the 3-piece group will persist in responding longer.

b. the 1-piece group will persist in responding longer.

c. as long as the constraints on the lever are the same, the groups will persist approximately the same length of time.

d. It is impossible to predict.

Operant Conditioning:

Operant conditioning is one of the main theories in behaviorism and also learning theory. This particular theory was pioneered by Edward Thorndike and B.F. Skinner. Its central tenet is that we learn by associating behavior with consequences.

Answer and Explanation:

Assuming that an increase in food quantity given corresponds to an increase in the value of the reward, then the answer to this question is A, the 3-piece group will persist in responding longer. The higher the value of the reward, the stronger the association, and the stronger the association the more it is impervious to extinction.
