The relationship between hormones and behavior is no longer viewed as a simple unidirectional effect of hormones on behavior. Rather, the view emerging from studies on animals observed in complex physical and social situations is that there is a sophisticated interplay between social contexts and hormonal status in the production of behavioral interactions. The present studies will further illuminate these relationships in callitrichid primates (marmosets and tamarins). Dr. French has previously shown that social relationships within mated pairs are extremely important in regulating the influence of hormones on behavior. The current studies will evaluate the effects of other social factors in modulating hormones effects on behavior. Specifically, Dr. French will assess whether or not responses of tamarins to unfamiliar intruders differ as a function of the intruding or resident female's reproductive status, will assess whether or not reproductively suppressed subordinate females are capable of expressing patterns of reproductive behavior when removed from the social context that produces suppression, and will evaluate the influence of visual access to unfamiliar pairs on patterns of reproductive behavior across the ovarian cycle. These studies are important in a number of ways. First, the work is relevant to propagation of endangered species. All marmosets and tamarins are considered threatened or endangered, and for some species (e.g., lion tamarins) there are more individuals in captivity than in the wild. It is highly likely that information critical for the enhancement of the propagation of these species in captivity will be the direct result of these studies. Hence, this research may have a profound impact on the maintenance of the biodiversity of tropical animals. Second,these studies will show how complex social settings can influence (reduce or magnify) the effects of internal physiological functions on behavior. These findings as a whole will contribute to a more complex and realistic view of hormones and behavior. Finally, these studies will evaluate hormone-behavior relationships in species of primates that have a social system with many common features of human societies (e.g., high degree of cooperative behavior, joint rearing of offspring, residence of older offspring in family or social groups).

激素与行为之间的关系不再被视为激素对行为的简单单向影响。 相反，对在复杂的身体和社会情境中观察到的动物进行的研究得出的观点是，社会背景和荷尔蒙状态在行为相互作用的产生中存在着复杂的相互作用。 目前的研究将进一步阐明卡利特里科灵长类动物（狨猴和狨猴）中的这些关系。 弗伦奇博士此前曾表明，配偶之间的社会关系对于调节激素对行为的影响极其重要。 目前的研究将评估其他社会因素在调节激素对行为的影响方面的影响。 具体来说，弗伦奇博士将评估狨猴对不熟悉的入侵者的反应是否会因入侵或居住雌性的生殖状态而有所不同，还将评估受到生殖抑制的从属雌性在脱离环境后是否能够表达生殖行为模式。产生抑制的社会背景，并将评估视觉接触陌生配对对整个卵巢周期生殖行为模式的影响。 这些研究在很多方面都很重要。 首先，这项工作与濒危物种的繁殖有关。 所有狨猴和狨猴都被视为受到威胁或濒临灭绝，对于某些物种（例如狮狨猴）来说，圈养的个体比野生的还要多。 这些研究的直接结果很可能是对增强这些物种在圈养条件下繁殖至关重要的信息。 因此，这项研究可能对热带动物生物多样性的维持产生深远的影响。 其次，这些研究将展示复杂的社会环境如何影响（减少或放大）内部生理功能对行为的影响。 这些发现作为一个整体将有助于对激素和行为产生更复杂和更现实的看法。 最后，这些研究将评估灵长类动物的激素与行为关系，这些灵长类动物的社会系统具有人类社会的许多共同特征（例如，高度合作行为、共同抚养后代、年长后代居住在家庭或社会群体中） 。
