Social grooming and coalition formation have been main foci in studies concerning altruism in monkeys. Results have been inconclusive because the altruistic nature of these behaviors remains unclear. I investigated altruism in a more transparent context via an apparatus in which captive long-tailed macaque females had the choice to exploit a food source themselves or to yield the food to a test partner. I hypothesized that if potential donors behaved altruistically toward kin, they would yield… 
Generous Leaders and Selfish Underdogs: Pro-Sociality in Despotic Macaques
It is shown that some despotic long-tailed macaques do grant others access to food, and their dominance hierarchy determines pro-social behavior in an unexpected way: high-ranking individuals grant, while low- ranking individuals withhold their partner access toFood.
Long-tailed macaques: an unfairness model for humans
It is suggested that the aversion observed in this species was associated with the degree of preference for the outcome (food type) offered rather than the distribution ratio, which could bring this species into irrationality.
Mechanisms influencing friendship in chimpanzees (Pan troglodytes): Kinship, familiarity or personality trait similarity?
It is concluded that chimpanzees show friendships, and similar kinship and kin recognition mechanisms operate in their formation and maintenance as those in human friendships.
Group service in macaques (Macaca fuscata), capuchins (Cebus apella) and marmosets (Callithrix jacchus): a comparative approach to identifying proactive prosocial motivations.
The results are consistent with the cooperative breeding hypothesis, and a comprehensive evaluation requires adding data from additional groups and species, which should be facilitated by the group service approach.
'Friendship' in Macaques : economics and emotions
When biologists and social scientist describe close bond among monkeys and humans, they describe the same homologue phenomenon, and the use of the term friendship for animals, therefore, seems justified.
On the psychology of cooperation in humans and other primates: combining the natural history and experimental evidence of prosociality
The comparison suggests that humans share with their closest living relatives reactive responses to signals of need, but differ in sensitivity to signs of need and cues of being watched, as well as in the presence of proactive prosociality.
Multimodal cues displayed by submissive rats promote prosocial choices by dominants
A two-choice task where rats can provide rewards to a conspecific in the absence of self-benefit was used, and which conditions promote prosociality by manipulating the social context of the interacting animals were interrogated.

Fight interference and altruism in rhesus monkeys
Fight interference data from a group of free-ranging rhesus monkeys used to test hypotheses about the evolution and importance of altruism suggest that the survival value and thus evolution of interference behavior involves factors acting through both the social and genetic levels of organization.
Development of partner preferences in Japanese Macaques (Macaca fuscata): Effects of gender and kinship during the second year of life
It is concluded that sex differences in behavioral frequencies become evident during the first year of life, andsex differences in partner preferences emerge during the second year oflife.

Kin and non-kin interventions in the aggressive disputes of vervet monkeys
Interventions in aggressive disputes were investigated in a free-living troop of vervets in Barbados, suggesting that reciprocation is a necessary component of non-kin interventions and the implications for the evolution of kin and reciprocal altruism were discussed.
Altruism Among Female Macaca Radiata: Explanations and Analysis of Patterns of Grooming and Coalition Formation
Analysis of the observed patterns of two forms of putative altruism among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors.
Functions of alliances in contests within wild gorilla groups
Primates frequently support other individuals in aggressive contests among group members. Several functions of such alliances have been suggested, some of them dependent on continued residence of
Social behavior of infant and mother Japanese Macaques (Macaca fuscata): Effects of kinship, partner sex, and infant sex
The behavioral interactions of 22 infant and mother Japanese macaques with other group members were studied. Focal-animal observations were made from the time of each infant’s birth until 1 year of
Interindividual distance and influence of dominance on feeding in a natural Japanese macaque troop
In a natural troop of Japanese macaques (Macaca fuscata yakui), the dominant-subordinate relationship restricted the feeding behavior of the subordinate in two ways: (1) the dominant drives away the
