Operant conditioning data pertaining to bar pressing in rats show that (1) different schedules of reinforcement during training lead to differential behavior during extinction as measured by number of responses, but not as measured by number of response units and (2) animals show a response frequency/unit of time which is directly proportional to the response frequency/unit of time acquired during training.
（1）训练期间不同的强化时间表会导致消退期间行为出现差异，这种差异以反应次数衡量，但不以反应单元数量衡量；（2）动物表现出的单位时间反应频率与训练期间获得的单位时间反应频率成正比。
