Male Japanese quail were conditioned to approach a visual CS that predicted an opportunity to copulate with a female quail. Subsequently the subjects were tested in both non-reinforced and reinforced test trials while sexually satiated and sexually deprived. In the satiation condition the sexual US was devalued by allowing the male subjects to copulate repeatedly with female birds just prior to testing. The subjects displayed significantly less approach to the CS when sexually satiated than when sexually deprived. These results are compatible with a mechanism in which performance of Pavlovian sexual approach conditioning is mediated by activation of a memorial representation of the US.
雄性日本鹌鹑被训练接近一个视觉条件刺激物，该刺激物预示着有机会与一只雌性鹌鹑交配。随后，在性满足和性剥夺的状态下，对这些实验对象进行了非强化和强化测试试验。在性满足状态下，通过让雄性实验对象在测试前与雌鸟反复交配，使性无条件刺激物的价值降低。与性剥夺时相比，性满足时实验对象对条件刺激物的接近行为明显减少。这些结果与一种机制相符，即巴甫洛夫式性接近条件反射的表现是由无条件刺激物的记忆表征的激活介导的。
