Social learning and endocrinology in primate infants

在这项研究中，我使用了小型灵长类动物，普通的狨猴，其中繁殖的雄性和哥哥姐姐以及繁殖的雌性在照顾婴儿方面发挥了积极的作用。我进行了一项新的食物测试，以调查每个家庭成员在遇到新的食物时如何影响婴儿的行为。研究发现，父母的存在，尤其是母亲的存在，促进了婴儿接触和食用新食物。此外，我还建立了一种测量狨猴尿液中催产素水平的方法。我将利用这一指标来研究家庭成员的存在对新型食品试验中婴儿行为的影响。

In this research, I used small primates, common marmosets in which breeding males and older siblings as well as breeding females take an active role in infant care. I conducted a novel food test to investigate how each family member affected the infants' behavior where they met novel foods. It was revealed that the presence of parents, especially mothers, facilitated infants' approach to and eating of novel foods. In addition, I established a method to measure the level of oxytocin in urine of marmosets. I will investigate the effect of the presence of family member on infants' behavior in the novel food test using this index.
