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...
متن کاملDetermining the Value of Social Companionship to Captive Tufted Capuchin Monkeys (Cebus apella)
This study used a method similar to one introduced by Dawkins in 1990 to assess the magnitude of the psychological need for social companionship in pair-housed tufted capuchin monkeys (Cebus apella). This method permits classification of commodities as necessities or luxuries. The study directly compared the commodity of social companionship to the commodity of food, a known physiological neces...
متن کاملHow capuchin monkeys (Cebus apella) quantify objects and substances.
Humans and nonhuman animals appear to share a capacity for nonverbal quantity representations. But what are the limits of these abilities? Results of previous research with human infants suggest that the ontological status of an entity as an object or a substance affects infants' ability to quantify it. We ask whether the same is true for another primate species-the New World monkey Cebus apell...
متن کاملDo 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...
متن کاملImplicit and explicit category learning by capuchin monkeys (Cebus apella).
Current theories of human categorization differentiate an explicit, rule-based system of category learning from an implicit system that slowly associates regions of perceptual space with response outputs. The researchers extended this theoretical differentiation to the category learning of New World primates. Four capuchins (Cebus apella) learned categories of circular sine-wave gratings that v...
