Four rats were trained to suppress responses in the presence of two separately presented stimuli that signalled shock in a conditioned-suppression paradigm. The two stimuli that signalled shock were then presented simultaneously to evaluate the effect of stimulus compounding on conditioned suppression. Two rats were tested by presenting the compound conditioned stimulus while conditioned suppression was being maintained to the individual conditioned stimuli. The other two rats were tested by giving them random presentations of the compound conditioned stimulus and the single conditioned stimuli during extinction of conditioned suppression. All four rats showed greater suppression to the compound stimulus than to either stimulus presented alone.
在条件性抑制范式中，训练了四只大鼠，使其在分别呈现的两种刺激出现时抑制反应，这两种刺激预示着电击。然后将这两种预示电击的刺激同时呈现，以评估刺激复合对条件性抑制的影响。通过在对单个条件刺激保持条件性抑制的同时呈现复合条件刺激，对两只大鼠进行了测试。通过在条件性抑制消退期间对另外两只大鼠随机呈现复合条件刺激和单个条件刺激，对它们进行了测试。所有四只大鼠对复合刺激的抑制作用都比对单独呈现的任何一种刺激的抑制作用更强。
