Seven pigeons were trained to respond on one key during the first half of a 60-s trial, and on another during the second half, to test the prediction that the rate of the internal pacemaker should slow in the absence of reward. The relative probability of responding was well-described by Erlang distributions, which yielded as parameters the period of the pacemaker and the criterial number of counts for switching to the second key. During a subsequent period of extinction the period increased linearly with time in extinction, and the criterial count decreased. This slowing of the pacemaker was predicted by the Behavioral Theory of timing, but not by other theories.
七只鸽子接受训练，在60秒试验的前半段对一个按键做出反应，后半段对另一个按键做出反应，以检验在没有奖励的情况下内部起搏器的速率应该减慢这一预测。反应的相对概率可以很好地用埃尔朗分布来描述，该分布产生起搏器的周期和切换到第二个按键的临界计数作为参数。在随后的消退期，该周期在消退过程中随时间呈线性增加，临界计数减少。起搏器的这种减慢是由计时行为理论预测的，而不是由其他理论预测的。
