Contents of learning that result from conditioned-unconditioned stimulus pairings in sexual approach conditioning were explored with male Japanese quail (Coturnix coturnix japonica). Sexual motivation of subjects conditioned to approach an arbitrary stimulus in a Pavlovian sexual conditioning paradigm was reduced by exposing them to a short photoperiod. Decreased sexual motivation resulted in a decline in sexually conditioned approach behavior (Experiments 1 and 2). Responding was restored when subjects were returned to a long photoperiod (Experiment 1) and when exogenous testosterone was administered (Experiment 2). Decreased sexual motivation did not affect food-conditioned approach behavior (Experiment 3). These results suggest that sexually conditioned approach behavior is mediated by a representation of the unconditioned stimulus, which is activated by the conditioned stimulus.
利用雄性日本鹌鹑（Coturnix coturnix japonica）探究了性接近条件反射中条件刺激与非条件刺激配对所产生的学习内容。在巴甫洛夫式性条件反射范式中，被条件化接近任意刺激的实验对象的性动机，通过将它们暴露在短光照周期下而降低。性动机的降低导致性条件化接近行为的下降（实验1和2）。当实验对象回到长光照周期（实验1）以及给予外源性睾酮时（实验2），反应恢复。性动机的降低并不影响食物条件化接近行为（实验3）。这些结果表明，性条件化接近行为是由非条件刺激的表征介导的，该表征由条件刺激激活。
