Data were obtained with rats on the effects of interresponse time contingent reinforcement of the lever press response using schedules in which interresponse times falling within either of two temporal intervals could be reinforced. Some of the findings were (a) the mode of the interresponse time distribution generally occurred near the first lower bound when the maximum reinforcement rate for the two lower bounds was equal; this also frequently occurred even when the reinforcement rate was less for the first lower bound; (b) as is the case with schedules using a single interval of reinforced interresponse times the values of the lower bounds partially determined the location and spread of the distributions; but the particular pair of values used did not seem to influence the effects of the probabilities of reinforcement; (c) although the modal interresponse time was usually at the lower bound of one of the two intervals of reinforced interresponse times, no simple relation existed between either the probability or rate of reinforcement of interresponse times in these two intervals and the location of this mode.
使用两种时间间隔中的任何一种内的反应间隔时间都可得到强化的程序，获取了关于大鼠杠杆按压反应的反应间隔时间依随强化作用效果的数据。一些研究结果如下：(a) 当两个下限的最大强化率相等时，反应间隔时间分布的众数通常出现在第一个下限附近；即使第一个下限的强化率较低时，这种情况也经常出现；(b) 与使用单个强化反应间隔时间的程序情况一样，下限值部分决定了分布的位置和离散程度；但所使用的特定一对值似乎并不影响强化概率的效果；(c) 尽管众数反应间隔时间通常处于两个强化反应间隔时间之一的下限，但这两个间隔中的反应间隔时间的强化概率或强化率与该众数的位置之间不存在简单的关系。
