After a period of equal reinforcement for choices of any job revealed which of 10 jobs each of 24 preschool children preferred and did not prefer, token payment became dependent on particular choices. Some children received tokens only for choosing previously non-preferred jobs, others for choosing previously preferred jobs. When tokens depended on choosing the nonpreferred jobs, those came to be preferred. When tokens depended on choosing the preferred jobs, the preferences were strengthened. The effects were replicated both within and between subjects, except in the case of one boy who consistently avoided token pay.
在对 24 名学龄前儿童的任意 10 种工作进行了一段时间的同等强化后，揭示了他们各自更喜欢和不喜欢哪些工作，代币支付开始取决于特定的选择。一些孩子只有选择之前不喜欢的工作才能获得代币，而另一些孩子只有选择之前喜欢的工作才能获得代币。当代币取决于选择不喜欢的工作时，这些工作就会变得更受欢迎。当代币取决于选择喜欢的工作时，这些偏好就会得到加强。这些影响在被试内和被试间都得到了复制，除了一个男孩始终回避代币支付的情况。
