Anticipatory level-changing behavior is a form of appetitive sexual behavior displayed by male rats prior to introduction of a female in a bilevel testbox. Analysis of this level-changing behavior may serve as assessment of sexual motivation. Because ejaculation affects appetitive aspects of sexual behavior, measures purporting to assess sexual motivation should be effected by ejaculation. We observed that ejaculation prior to testing reduced the number of anticipatory level changes of a male rat. This reduction was greater when tested after two than after one ejaculation. Our results support the concept that analysis of anticipatory level-changing behavior can be used to measure sexual motivation.
预期性水平变化行为是雄性大鼠在双水平测试箱中引入雌性大鼠之前所表现出的一种欲求性性行为形式。对这种水平变化行为的分析可作为性动机的评估。由于射精会影响性行为的欲求方面，旨在评估性动机的指标应受射精影响。我们观察到，测试前射精会减少雄性大鼠预期性水平变化的次数。两次射精后测试时这种减少比一次射精后测试时更明显。我们的结果支持这样的观点，即对预期性水平变化行为的分析可用于测量性动机。
