Many of our attitudes about food and eating are developed during childhood. Thus, the health and nutritional condition of the child, and of the subsequent adult, are shaped by childhood feeding experiences. However, our understanding of how food preferences, eating habits and skills are learned is still very rudimentary. We do know that human infants rely, to a much greater extent than perhaps any other mammal, on social means to acquire food-related information. The marmosets and tamarins are unique among non-human primates in the degree to which family members provision weaned young, much as we humans provision our young. This study proposes to use the golden lion tamarin as a model for the study of the development of food selection and eating habits in humans. It will focus on the interplay between independent trial and error learning and social learning about food during the tamarins' first year of life. Field observations and collection for nutritional analysis of food types given to immature tamarins by older group members will be used to examine the functions of provisioning, to describe the various means by which young acquire food and how these food acquisition strategies change during ontogeny, and to describe the roles of caretakers in determining food intake by the young. Behavioral experiments designed to measure the effects of food familiarity on food transfer interactions will be conducted on captive family groups to further examine the functions of provisioning. Playback experiments of infant begging calls also will be conducted on groups in captivity in order to more clearly assess the costs of begging for food by the young. Thus, natural variation in the behavior of wild animals and controlled experimental variation will be used to test hypotheses regarding the development of food selection and foraging skills.

我们对食物和饮食的许多态度都是在童年时期形成的。 因此，儿童的健康和营养状况以及随后的成人的健康和营养状况是由儿童时期的喂养经历形成的。 然而，我们对食物偏好、饮食习惯和技能是如何习得的理解仍然非常初级。 我们确实知道，人类婴儿可能比其他任何哺乳动物都更依赖社会手段来获取与食物有关的信息。 绒猴和绢毛猴在非人类灵长类动物中是独一无二的，它们的家庭成员提供断奶后的幼崽，就像我们人类提供幼崽一样。 本研究拟以金狮绢毛猴为模式动物，研究人类食物选择和饮食习惯的发育。 它将重点关注在绢毛猴生命的第一年，独立的试错学习和社会学习之间的相互作用。 实地观察和收集的食物类型的营养分析，以不成熟的绢毛猴的老年组成员将被用来检查功能的规定，描述的各种手段，年轻人获得食物和这些食物的获取策略如何在个体发育过程中的变化，并描述的角色照顾者在确定食物摄入量的年轻人。 行为实验旨在测量食物熟悉度对食物转移相互作用的影响，将进行圈养家庭群体，以进一步研究供应的功能。还将在被囚禁的群体中进行婴儿乞讨电话的回放实验，以便更清楚地评估年轻人乞讨食物的成本。 因此，野生动物行为的自然变异和受控的实验变异将被用来检验关于食物选择和觅食技能发展的假设。
