Examining Social Dominance and Food Sharing in Cotton-Top Tamarins (Saguinus oedipus)

Honor Student Examining Social Dominance and Food Sharing in Cotton-Top Tamarins (Saguinus oedipus)

Department: Psychology
Symposium Year: 2013
Student(s): Ashley Harold, Iruka Ndukuba
Faculty Mentor(s): Dr. Erica Kennedy

 

In our study, we investigated whether social dominance affected food sharing in our male-female tamarin pairs. Tamarins were initially presented with a choice of two food items, and the preference of each monkey was recorded before the study. Most monkeys, with the exception of one, clearly preferred the same food item at least two out of three times. During the study, the tamarin pairs were presented with several pieces of the same two types of food items (one being more desirable and one being less desirable) on a cart within the tamarins’ cage. We recorded which of the animals attained the majority of the food and examined gender differences in food acquisition and behavioral reactions of each tamarin.
