Capuchin monkey research priorities and urgent issues.

Insight From Capuchin Monkey Studies: Ingredients of, Recipes for, and Flaws in Capuchins’ success Elisabetta Visalberghi Many years ago, while passing in front of a group of capuchin monkeys (Cebus apella) at the Rome Zoo, I was lucky to see an adult male pounding an unshelled peanut with a boiled potato. Why was he behaving like this.

Similarly, our female capuchin monkey posed no problem in discriminating orange versus green stimuli, a condition which male capuchins were unable to solve. It is possible that male capuchin monkeys may compensate the reduced color vision by some peculiar organizational arrangement of the visual system or by some cognitive mechanism.

Using a custom-developed computer program, “Color Vision Simulator” (CVS), we adjusted the chromaticity of digital images to accord with the known photopic color sensitivities of the six different capuchin monkey phenotypes. This is based on the presumption that our method represents a reasonable first-order approximation of how food.

Downloadable! Behavioral economics has demonstrated systematic decision-making biases in both lab and field data. But are these biases learned or innate? We investigate this question using experiments on a novel set of subjects — capuchin monkeys. By introducing a fiat currency and trade to a capuchin colony, we are able to recover their preferences over a wide range of goods and risky choices.

Monkey Business. Sarah has released a study helping prove that primates share similar feelings of inequity to humans and she will extend the research with a five-year National Science Foundation grant. In the next round of research, Sarah will work with Bart Wilson at Chapman University to do similar hands-on and computer game-like experiments.

Abstract An experimental study with captive individuals and study of video recordings of wild monkeys explored whether and how tufted capuchin monkeys use onehand to hold one or more objects with m.

Background Decades of research have revealed rich cultural repertoires encompassing multiple traditions in wild great apes, a picture crucially complemented by experimental simulations with captive apes. Studies with wild capuchin monkeys, the most encephalized simian species, have indicated a New World convergence on these cultural phenomena, involving multiple traditions and tool use.

The student will carry out quantitative research on the movement patterns of white-faced capuchin monkey populations that have been the subject of long-term study and investigate whether immigration impacts the information groups have about their environment and changes their movement strategies.

My research investigates whether the ability to categorize money can be traced back to non-human primates, by analyzing the exchange behavior of brown-tufted capuchin monkeys. This research is done in collaboration with the Unit of Cognitive Primatology of Rome and the Institut Jean Nicod in Paris.

Abstract. Asking how socially intelligent capuchin monkeys are seems interesting and important for at least two reasons. The first reason is that they are New World monkeys, and answering this question gives us insights into the origin of this aspect of intelligence in the primate order.
