在4个实验中，作者使用大鼠来检查在光存在下，在听觉刺激单独与食物配对后，在相同光存在下，在点击音复合期间的反应强度。实验1表明，当光的持续时间较短而不是较长时，复合物的反应速率较高。在实验2、3和4中，长持续时间的光被用作涉及音调和响片的条件性辨别中的食物信号。通过这种处理增强了在光照期间用点击音化合物对测试试验的响应，并导致与光照持续时间短时观察到的性能水平没有不同的性能水平。这些结果与联想学习的基本理论相比，更符合一种理论。
In 4 experiments, the authors used rats to examine the strength of responding during a clicker-tone compound in the presence of a light, after the auditory stimuli had individually been paired with food in the presence of the same light. Experiment 1 demonstrated a higher rate of responding during the compound when the duration of the light was short rather than long. In Experiments 2, 3, and 4, the long duration light was used as a signal for food in a conditional discrimination involving the tone and the clicker. Responding on test trials with the clicker-tone compound during the light was enhanced by this treatment and resulted in a level of performance that was no different from that observed when the duration of the light was short. The results are more compatible with a configural than an elemental theory of associative learning.
