Compete to Play: Trade-Off with Social Contact in Long-Tailed Macaques (Macaca fascicularis)
Experimental manipulation of competitive contexts in primates reveals common mental processes involved in social judgment, and shows that access to valuable resources can be a sufficient cause for variations in group cohesion.
Long-tailed macaques (Macaca fascicularis) understand what conspecifics can see in a competitive situation
This work has provided the first unequivocal evidence of VPT in a monkey species, suggesting that this precursor to ToM is an evolutionarily conserved capacity present in monkeys, apes and humans.
Variation in withholding of information in three monkey species
The results supported the predictions based on interspecific differences in the strictness of the dominance hierarchy and the degree of fission–fusion dynamics, with the former constraining the subjects' tendency to approach the box and the latter affecting the subjects’ tendency to wait for the appropriate situation to retrieve the food.
Testing kin altruism in long-tailed macaques (Macaca fascicularis) in a food-sharing experiment

Social grooming and coalition formation have been main foci in studies concerning altruism in monkeys, and it is hypothesized that if potential donors behaved altruistically toward kin, they would yield the food sources longer to kin than to nonkin.
Dominance Styles of Female and Male Barbary Macaques (Macaca Sylvanus)
Dominance styles can be understood as consequences of different competition regimes imposed by socio-ecological conditions. As vital resources differ for males and females of the same species, one
Results in game condition indicate that Piagetian object permanence tests may be interpreted by both dogs and humans not only as object hiding and finding tasks, but, alternatively, as social-behavioural games of different sorts that may contribute to the systematic search performance.
Are capuchin monkeys (Cebus apella) inequity averse?
It is argued that capuchins' refusals were due to the frustration of seeing and not obtaining the PF, and that seeing the partner eating increases the LPF acceptance.
Food transfers through mesh in brown capuchins.
The study suggests that sharing mechanisms may be different for adult male capuchins, with males sharing food more readily and less discriminatingly than females.
Early understanding of cues of possession
Early understanding of cues of possession The concept of ownership refers to a particular relationship between several individuals and an object. The relationship consists of the power of an


Triadic differentiation: an inhibitory process protecting pair bonds in baboons.
Analysis shows that the inhibition suppresses friendly as well as aggressive approaches in the rival, thus keeping him away from the pair, and the formation of triads thus seems to reduce two of the component dyadic relationships while furthering the third.
Possession and Transfer of Objects in a Group of Brown Capuchins (Cebus Apella)
Possession of objects was studied in a captive group of kin-related brown capuchin monkeys (Cebus apella). Following introduction of an object by the experimenter, social interactions around the
Competitive behavior in male, female, and pseudohermaphroditic female dogs.
Developmentally androgenized females differed from members of their own sex, but they differed just as greatly from normal males.
Modification of aggression through socialization and the special case of adult and adolescent male rhesus monkeys (Macaca mulatta)
As a consequence of adult response to the agonistic behavior of adolescent males, maturing males selectively target other older males, avoid aggression against females and immatures; (2) form alliances with other males; and (3) become progressively isolated from their matrilines.
Age-sex differences in the expression of agonistic behavior in rhesus monkey (Macaca mulatta) groups.
Adolescent males received high frequencies of aggressive responses, and this is hypothesized to account for the marked shift in adult male patterns of participation in intragroup agonistic interactions, as relative to females whose basic pattern of agonistic expression does not change with age.
