在定比时刻表中经常混淆的两个变量是加固频率和反应要求。这些变量是通过一种技术分离出来的，该技术将一组鸽子的增援时间分布与按不同固定比率时间表反应的鸽子的时间分布联系起来。然后，通过在它们的日程表中添加各种串联固定比率要求来操纵带轭的鸟的意外情况。加强后的停顿对于颈鸽和比率鸽来说大致相同，并且对串联要求的变化相对不敏感。末端应答率随着串联需求的增加而增加，即使增强率不变。这一增加归因于串联要求与长反应间隔时间的差别强化的逐步干扰。
Two variables often confounded in fixed-ratio schedules are reinforcement frequency and response requirement. These variables were isolated by a technique that yoked the distributions of reinforcements in time for one group of pigeons to those of pigeons responding on various fixed-ratio schedules. The contingencies for the yoked birds were then manipulated by adding various tandem fixed-ratio requirements to their schedules. Post-reinforcement pause was approximately equal for the yoked and ratio pigeons, and was relatively insensitive to changes in the tandem requirement. Terminal response rate increased with increases in the tandem requirement, even though reinforcement rate was invariant. This increase was attributed to the progressive interference of the tandem requirement with the differential reinforcement of long interresponse times.
