在第1和第3阶段，两只日本猴对多变量比率80变量间隔X时间表做出反应，其中X的值被调整以确保时间表间强化率相等。在提供食物颗粒后，组件严格交替，每次会议在50个组件后结束。第二阶段与其他阶段的不同之处仅在于，之前在会议期间获得的50个颗粒在会议结束时一起交付。可变比率应答率在各阶段均未降低，但可变间期应答率在II期手术期间大幅降低。这一比率的下降是由于食物在会议结束时的操纵删除更大的即时性的强化所提供的短interresponse时间相对于长interresponse时间。如果没有这种时间偏好短interresponse时间，可变间隔interresponse时间强化反馈功能在很大程度上控制响应发射，指示响应率降低。这一结果可以用“现值最大化”的经济学概念来解释。"
In Phases 1 and 3, two Japanese monkeys responded on a multiple variable-ratio 80 variable-interval X schedule, where the value of X was adjusted to ensure equal between-schedule reinforcement rates. Components strictly alternated following the delivery of a food pellet, and each session ended following 50 components. Phase 2 differed from the others only in that the 50 pellets previously earned during the session were delivered together at session's end. Variable-ratio response rates did not decrease across phases, but variable-interval response rates decreased substantially during the Phase 2 procedure. This rate decrease was attributed to the food-at-session's-end manipulation removing the greater immediacy of reinforcement provided by short interresponse times relative to long interresponse times. Without this time preference for short interresponse times, the variable-interval interresponse-time reinforcement feedback function largely controlled response emission, dictating a response-rate reduction. This result was explained in terms of the economic notion of "maximizing present value."
