Abstract
Reinforcement for the pressing of a bar was administered to 4 groups of rats ( n = 40) immediately, or after a steadily increasing, steadily decreasing, or fixed 45-sec. delay. Those in the group receiving an increasing delay of reward were significantly more resistant to extinction than the other groups. Implications for Amsel's frustration hypothesis are discussed.
