Use of experimenter-given cues during object-choice tasks by capuchin monkeys
Article Abstract:
Object choice tasks are examined on three capuchin monkeys, Cebus apella, when the experimenter provides cues for object identification under the three cue conditions of gazing at the correct object, gazing plus pointing and pointing alone. Experimenter's gazing at the correct object is not used by the subject as a cue, while gazing plus pointing and pointing are used. Reduced cue-response spatial contiguity could have caused the failure to use experimenter's gazing, which could also be due to restricted mental or visual perspective-taking.

Grooming down the hierarchy: allogrooming in captive brown capuchin monkeys
Article Abstract:
Dominant females tend to be most involved in grooming in female groups of brown capuchin monkeys in captivity. Alpha females were the one group that gave more grooming than it received. This is a different pattern from that observed with some other primates such as baboons and vervets. Grooming also tends to take place more often among females of a similar rank and this is a similarity with grooming patterns seen in monkey species from the Old World.

Self-recognition in Saguinus: a critical essay
Article Abstract:
Research data shows that self-recognition in non-human primates is only present in the great ape species, which includes orang-utans, chimpanzees, gorillas and bonobos. A recent study by Hauser et al. in 1995 also claims evidence of self-recognition in the cotton-top tamarin, Saguinus oedpipus. However, the evidence presented is inadequate because it focuses, almost exclusively, on the mark test.
