据报道，动物更愿意“工作”而不是“吃白吃”。然而，造成这种现象的变量尚不清楚。两只鸽子接受训练，按固定比例 300 次啄食食物。接下来，支撑食物料斗以允许连续获取食物，并控制料斗灯的存在或不存在。当漏斗灯按照固定比例的时间表呈现时，就会发生啄键；当它没有出现时，敲击键盘就停止了。因此，在存在免费食物的情况下的响应被证明是料斗灯的调节增强特性的函数。
It has been reported that animals will “work” in preference to “freeloading.” However, the variables responsible for this phenomenon are not well understood. Two pigeons were trained to keypeck for food on a fixed-ratio 300 schedule. Next, the food hopper was propped up to permit continuous access to food, and the presence or absence of the hopper light was manipulated. When the hopper light was presented contingent upon the fixed-ratio schedule, keypecking occurred; when it was not presented, keypecking ceased. Thus, responding in the presence of free food was shown to be a function of the conditioned reinforcing properties of the hopper light.
