Capuchins (Cebus apella) can solve a means-end problem.
Three capuchin monkeys (Cebus apella) were tested on a 2-choice discrimination task designed to examine their knowledge of support, modeled after Hauser, Kralik, and Botto-Mahan's (1999) experiments with tamarins. This task involved a choice between 2 pieces of cloth, including 1 with a food reward placed on its surface, and a second cloth with the food reward next to its surface. After reliabl...
متن کاملDevelopment of maze navigation by tufted capuchins (Cebus apella).
Theories of spatial navigation hypothesize that animals use vector or topological information to choose routes, often including detours, to move objects or themselves to goals. We assessed adult capuchin monkeys' (Cebus apella) navigation through 192 virtual two-dimensional mazes that incorporated detour problems. Six monkeys initially were significantly less likely to choose the correct paths ...
متن کاملChoosing and using tools: capuchins (Cebus apella) use a different metric than tamarins (Saguinus oedipus).
Cotton-top tamarins (Saguinus oedipus) selected canes positioned so that a straight inward pull brought food within reach (M. D. Hauser, 1997; see also record 1997-41347-003). Tamarins failed to retrieve food with canes in other positions, and they did not reposition these canes. In this study, tufted capuchin monkeys (Cebus apella) preferred canes they could pull straight in when these were pr...
متن کاملNavigating two-dimensional mazes: chimpanzees (Pan troglodytes) and capuchins (Cebus apella sp.) proWt from experience diVerently
We examined whether navigation is impacted by experience in two species of nonhuman primates. Five chimpanzees (Pan troglodytes) and seven capuchin monkeys (Cebus apella) navigated a cursor, using a joystick, through two-dimensional mazes presented on a computer monitor. Subjects completed 192 mazes, each one time. Each maze contained one to Wve choices, and in up to three of these choices, the...
متن کاملPersonality and facial morphology: Links to assertiveness and neuroticism in capuchins (Sapajus [Cebus] apella).
Personality has important links to health, social status, and life history outcomes (e.g. longevity and reproductive success). Human facial morphology appears to signal aspects of one's personality to others, raising questions about the evolutionary origins of such associations (e.g. signals of mate quality). Studies in non-human primates may help to achieve this goal: for instance, facial widt...
