大鼠暴露于两个组件的多个时间表的食物输送。在第一个实验中，需要15种反应才能在两种成分中产生食物。在一个组件中操作响应杆总是需要0.25 N（25 g）的向下力。在另一种情况下，所需的力为0.25、0.50、1.00或2.00 N（25、50、100或200 g）。在第二个实验中，0.25 N的力在一个分量中操作杠杆，但在另一个分量中，在每个比率的开始、中间或结束时五个连续响应的力要求从0.25 N增加到2.00 N。在第三个实验中，生产食物所需的反应次数从15次减少到5次，然后减少到1次。再次检查了将响应力从0.25 N改变为2.00 N的影响。在一般情况下，在所有的实验中，响应力增加，平均响应率下降，平均interresponse时间增加。
Rats were exposed to two-component multiple schedules of food delivery. In the first experiment, 15 responses were required to produce food in both components. A downward force of 0.25 N (25 g) was always required to operate the response lever in one component. In the other, the required force was 0.25, 0.50, 1.00, or 2.00 N (25, 50, 100, or 200 g). In the second experiment, 0.25 N of force operated the lever in one component, but in the other, the force requirement for five consecutive responses at the beginning, middle, or end of each ratio was increased from 0.25 to 2.00 N. In the third experiment, the number of responses required to produce food was reduced from 15 to 5, and then to 1. Again, the effects of altering response force from 0.25 to 2.00 N were examined. In general, as response force increased in all experiments, mean response rates decreased and mean interresponse times increased.
