Give What You Get: Capuchin Monkeys (Cebus apella) and 4-Year-Old Children Pay Forward Positive and Negative Outcomes to Conspecifics

The breadth of human generosity is unparalleled in the natural world, and much research has explored the mechanisms underlying and motivating human prosocial behavior. Recent work has focused on the spread of prosocial behavior within groups through paying-it-forward, a case of human prosociality in which a recipient of generosity pays a good deed forward to a third individual, rather than back...

Journal of Experimental Psychology: Animal Learning and Cognition Do You See What I See? A Comparative Investigation of the Delboeuf Illusion in Humans (Homo sapiens), Rhesus Monkeys (Macaca mulatta), and Capuchin Monkeys (Cebus apella)

Do capuchin monkeys (Cebus apella) use tokens as symbols?

In the absence of language, the comprehension of symbols is difficult to demonstrate. Tokens can be considered symbols since they arbitrarily stand for something else without having any iconic relation to their referent. We assessed whether capuchin monkeys (Cebus apella) can use tokens as symbols to represent and combine quantities. Our paradigm involved choices between various combinations of...

Postconflict behaviour in brown capuchin monkeys (Cebus apella).

Postconflict affiliation has been mostly studied in Old World primates, and we still lack comparative research to understand completely the functional value of reconciliation. Cebus species display great variability in social characteristics, thereby providing a great opportunity for comparative studies. We recorded 190 agonistic interactions and subsequent postconflict behaviour in a captive g...

Face recognition in capuchin monkeys (Cebus apella).

Primates live in complex social groups that necessitate recognition of the individuals with whom they interact. In humans, faces provide a visual means by which to gain information such as identity, allowing us to distinguish between both familiar and unfamiliar individuals. The current study used a computerized oddity task to investigate whether a New World primate, Cebus apella, can discrimin...
