Killeen and Fetterman's (1988) behavioral theory of animal timing predicts that decreases in the rate of reinforcement should produce decreases in the sensitivity (A') of temporal discriminations and a decrease in miss and correct rejection rates (decrease in bias toward "long" responses). Eight rats were trained on a 10- versus 0.1-s temporal discrimination with an intertrial interval of 5 s and were subsequently tested on probe days on the same discrimination with intertrial intervals of 1, 2.5, 5, 10, or 20 s. The rate of reinforcement declined for all animals as intertrial interval increased. Although sensitivity (A') decreased with increasing intertrial interval, all rats showed an increase in bias to make long responses.
基林和费特曼（1988年）的动物计时行为理论预测，强化速率的降低会导致时间辨别敏感度（A'）下降，漏报率和正确拒斥率降低（偏向“长”反应的偏差减小）。八只大鼠接受了10秒与0.1秒的时间辨别训练，试间间隔为5秒，随后在探测日以1秒、2.5秒、5秒、10秒或20秒的试间间隔对相同辨别任务进行测试。随着试间间隔增加，所有动物的强化速率均下降。尽管敏感度（A'）随着试间间隔增加而降低，但所有大鼠做出长反应的偏差均增加。
