我们描述了一种测量雄性大鼠工具性行为的新方法，通过使用性强化的二级时间表，雌性发情。该范式的实验评估和验证是通过检验(a)条件刺激在维持工具反应方面的重要性（通过测量在测试过程中条件刺激被忽略的影响），(b)通过测量每种操作对为食物工作的动物和为雌性工作的动物的影响，对射精后不应期（性不兴奋期）和食物饱腹感的工具行为的影响和动机特异性进行的。(c)用不发情的雌性代替发情的雌性作为获得的奖励的效果，以及(d)性行为的条件和非条件测量之间的相关性。我们的结论是，二阶范式提供了一种区分神经内分泌操作对性行为表达背后的激励、动机和表现变量的影响的方法。
We describe a novel procedure for measuring instrumental sexual behavior in the male rat by using a second-order schedule of presentation of sexual reinforcement, an estrous female. Experimental assessment and validation of the paradigm have been achieved by examining (a) the importance of the conditioned stimulus in maintaining instrumental responding by measuring the effects of its omission during a test session, (b) the effects and motivational specificity on instrumental behavior of the postejaculatory refractory period (a period of sexual unarousability) and of satiety for food by measuring the impact of each manipulation on animals working for food and for a female, (c) the effects of replacing an estrous female with an anestrous one as the earned reward, and (d) the correlations between conditioned and unconditioned measures of sexual behavior. We conclude that the second-order paradigm provides a means of distinguishing between the effects of neuroendocrine manipulations on incentive motivational and performance variables underlying the expression of sexual behavior.
