Four adult female Callimico were studied in terms of their sexual motivation relative to three unrelated adult males using an operant paradigm followed by a pair test or a two-male choice test. Reductions in urinary cortisol concentrations and the duration of immobility were used as indicators of subjects' adjustment to the experimental situation. When females were tested with unfamiliar males there was no effect of ovarian state on operant or species-typical measures of female sexual motivation. When females were retested with the same males after a 1-week familiarization, sexual motivation was higher during the peri-ovulatory phase than during the post-ovulatory phase in terms of operant but not in terms of species-typical proceptive behavior or in terms of receptive behavior. During the familiarization periods, female sociopositive behavior and sexual motivation demonstrated marked variation depending on the identity of the male. Males with which females demonstrated high sexual motivation during familiarization were the object of equal amounts of female operant behavior during pair tests and two-male choice tests; males with which females had demonstrated low sexual motivation were the objects of less female sexual motivation under conditions of female choice than in pair tests.
我们使用操作性范式，随后进行配对测试或双雄性选择测试，对4只成年雌性伶猴相对于3只无关成年雄性的性动机进行了研究。尿皮质醇浓度的降低和静止不动的持续时间被用作受试者对实验情境适应程度的指标。当雌性与陌生雄性进行测试时，卵巢状态对雌性性动机的操作性或物种典型测量指标没有影响。在经过1周的熟悉期后，当雌性与相同的雄性再次进行测试时，就操作性而言，排卵期周围阶段的性动机高于排卵后阶段，但就物种典型的求偶行为或接受行为而言并非如此。在熟悉期内，雌性的社会积极行为和性动机根据雄性的身份表现出显著差异。在熟悉期内雌性表现出高性动机的雄性，在配对测试和双雄性选择测试中是雌性等量操作性行为的对象；在熟悉期内雌性表现出低性动机的雄性，在雌性选择条件下比在配对测试中受到的雌性性动机更少。
