以雄性日本鹌鹑为研究对象，探讨了条件-非条件刺激配对在性接近条件反射中的学习内容。在巴甫洛夫性条件反射范式中，受试者的性动机被限制为接近任意刺激，通过将他们暴露于短的光周期来降低。性动机的降低导致性条件接近行为的下降（实验1和2）。当受试者恢复到长光周期（实验1）和外源性睾酮（实验2）时，反应恢复。降低性动机并不影响食物条件的方法行为（实验3）。这些结果表明，性条件接近行为介导的代表性的非条件刺激，这是激活的条件刺激。
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.
