This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Objective: To determine the facilitators of good parenting in primates. As in humans, cooperative breeding marmosets and tamarins show a considerable amount of father directed infant care. However, marmoset and tamarin fathers spend more time than the mother caring for infants. Fathers before delivery show hormonal changes that facilitate infant responsiveness. We found that experienced father marmosets are highly but variably responsive to infants. Males tested for their infant responsiveness are highly motivated to respond to a live infant or to vocalizations produced by an infant. We found that males with lowered prolactin also showed lower responsiveness to infant cues while males who had the highest levels of testosterone prior to infant birth also show the most responsiveness to infant cues. Additionally causal studies indicate that prolactin helps regulate weight in marmosets and tamarin monkeys. Lowering prolactin is associate with fathers losing a significant amount of weight during the infant period while increasing prolactin prevents weight loss with infant care. We suggest that there are hormonal conditions that faciliate male parental care in the marmoset monkey. This research used WNPRC Assay Services. NIH MIMH funding ended before this reporting period; three publications have resulted.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 目的：确定灵长类动物良好养育的促进因素。 与人类一样，狨猴和狨猴的合作繁殖表现出相当多的父亲指导的婴儿护理。然而，狨猴和狨猴的父亲照顾婴儿的时间比母亲多。 父亲在分娩前会出现荷尔蒙变化，从而促进婴儿的反应。我们发现，经验丰富的狨猴爸爸对婴儿的反应高度但各不相同。 测试婴儿反应能力的男性非常积极地对活婴儿或婴儿发出的声音做出反应。 我们发现，催乳素较低的男性对婴儿提示的反应也较低，而婴儿出生前睾酮水平最高的男性对婴儿提示的反应也最强。 此外，因果研究表明，催乳素有助于调节狨猴和狨猴的体重。 降低催乳素与父亲在婴儿期体重减轻有关，而增加催乳素则可以防止婴儿护理时体重减轻。 我们认为，存在有利于狨猴雄性父母照顾的激素状况。 本研究使用了 WNPRC 检测服务。 NIH MIMH 资助在本报告期之前结束；已出版三份出版物。
