Relationships Between Personality Type And Cognitive Ability In Marmoset Monkeys (Callithrix Jacchus), Zachary Marciano

Masters Theses

Personality refers to multiple traits that are thought to be stable over time and across situations. It is recognized that personality has a neural basis and is associated with health outcomes. Whether personality is also associated with cognitive ability, however, is still a matter of intense debate. One way to examine these potential relationships is to use a nonhuman primate model for which complexities present in humans can be minimized. Recent research into the varying personality types of marmoset monkeys suggests that there are predominantly three to five core primary domains that most marmosets and other primates can be categorized …

One Year Change In Cognitive Function In Male And Female Common Marmosets (Callithrix Jacchus), Brianna Healey

Masters Theses

Long term cognitive studies in humans and nonhuman primates such as macaques are difficult because of their long lifespan. The common marmoset (Callithrix jacchus) is a non-human primate who shares with humans many features characteristic of primates, including a complex brain and cognitive function. They also have a short lifespan (~10 years) that makes them a great model in studies of cognitive aging. This study focuses on the rate of decline in cognitive function in male and female marmosets based on performance on reversal learning tasks over 2 years of testing.

We found that marmosets improved their overall …
