Rats were exposed to an interlocking fixed-ratio 150 fixed-interval 5-minute schedule of food reinforcement and then to yoked variable-ratio schedules in which individual ratios corresponded exactly to the ratios of responses to reinforcement obtained on the interlocking schedule. After additional training with the interlocking schedule, the rats were exposed to yoked variable-interval schedules in which intervals corresponded to the intervals between successive reinforcements obtained on the second interlocking schedule. Response rates were highest in the yoked VR condition and lowest in the yoked VI, while intermediate rates characterized the interlocking schedule. Break-run patterns of responding were generated by the interlocking schedule for all subjects, while both the yoked VR and VI schedules produced comparatively stable local rates of responding. These results indicate that responding is sensitive to the interlocking schedule's inverse relationship between reinforcement frequency and responses per reinforcement.
将大鼠暴露于一种相互关联的固定比率150、固定间隔5分钟的食物强化程序，然后再暴露于配对的可变比率程序，其中个体比率与在相互关联程序中获得的强化反应比率完全对应。在对相互关联程序进行额外训练后，将大鼠暴露于配对的可变间隔程序，其中间隔与在第二个相互关联程序中获得的连续强化之间的间隔相对应。反应率在配对可变比率条件下最高，在配对可变间隔条件下最低，而中间比率则是相互关联程序的特征。所有受试者的相互关联程序产生了反应的中断-持续模式，而配对可变比率和可变间隔程序都产生了相对稳定的局部反应率。这些结果表明，反应对相互关联程序中强化频率与每次强化反应之间的反比关系敏感。
