Previous results suggest that a stimulus paired in Pavlovian fashion with reward should exert some discriminative control over an unrelated operant response acquired under a different drive-reward system. In the following experiment, a stimulus was first paired with food reinforcement for a hungry rat. Subsequently, the animal learned to lever-press for water reinforcements when thirsty but not hungry. Finally, the control over lever-pressing of the food-paired stimulus was tested by presenting it at various times during extinction of the lever-pressing response. All animals in the experiment showed the expected effect; each emitted more lever-presses during periods of the food-paired stimulus than during alternate control periods.
先前的研究结果表明，在巴甫洛夫条件反射模式下与奖励配对的刺激，应对在不同驱力-奖励系统下习得的不相关操作性反应施加某种辨别性控制。在接下来的实验中，首先将一种刺激与饥饿大鼠的食物强化配对。随后，当动物口渴但不饥饿时，它学会了按压杠杆以获取水强化物。最后，通过在按压杠杆反应消退期间的不同时间呈现与食物配对的刺激，来测试该刺激对按压杠杆的控制作用。实验中的所有动物都表现出预期的效果；每只动物在与食物配对的刺激期间比在交替的对照期间发出更多的按压杠杆行为。
