四个实验评估了试验(T)和试验间(I)持续时间对大鼠弹夹接近行为的影响。在实验1和实验2中，不同组的动物接受了不同的I和T持续时间的组合。就达到各种获取标准所需的试验次数而言，获得速度通常在接受大I：T比训练的小组中更快。具有相同I：T比但具有不同绝对I和T持续时间的训练组之间的习得率和终端反应率也存在差异。在不同的I和T持续时间组合的普通测试中，条件反射结束时明显的差异持续存在。实验3和实验4对两类一般理论的预测进行了更具体的测试，发现结果与那些将群体差异描述为表明学习差异而不是表现出差异的理论一致。
Four experiments assessed the effects of trial (T) and intertrial (I) durations on magazine approach behavior in rats. In Experiments 1 and 2, different groups of animals were conditioned with various combinations of I and T durations. The rate of acquisition, in terms of the number of trials required to reach various acquisition criteria, generally was faster in groups trained with large I:T ratios. There also were differences in rate of acquisition and terminal response rates between groups trained with identical I:T ratios but with different absolute I and T durations. Differences evident at the end of conditioning persisted during a common test with various combinations of I and T durations. Experiments 3 and 4 provided a more specific test of the predictions of 2 general classes of theories and found results that were consistent with those theories that characterize group differences as indicative of differences in learning, rather than in performance.
