Comparative Cognition & Behavior at Bucknell
Regina Paxton Gazes

Our research focuses on understanding the intersection of cognition and behavior

To understand the evolutionary roots of behavior and cognition, we study similarities and differences between closely related species.

Simple Primate Phylogeny 

The Bucknell Animal Behavior Lab houses four species of primates; two New World primate species, Capuchin and Squirrel monkeys, and two Old World primate species, Hamadryas baboons and Lion tailed macaques.



We answer questions about what processes, or combination of processes, contribute to cognitive behavior in areas such as memory, space, sociality, and magnitude.

Using touch screen computers and RFID technology, we explore cognitive processes in socially housed monkeys. Monkeys can choose to participate in cognitive testing at their own pace, anytime of day.

Because our primates are socially housed, we collect behavioral and cognitive data on the same individuals to examine relationships between behavior and cognition. 

Our primate groups are made up of animals of all ages, which allows us to study differences in cognition and behavior across the lifespan, from infancy through old age.
