Tolerance for inequity may increase with social closeness in chimpanzees.
Economic decision-making depends on our social environment. Humans tend to respond differently to inequity in close relationships, yet we know little about the potential for such variation in other species. We examine responses to inequity in several groups of chimpanzees (Pan troglodytes) in a paradigm similar to that used previously in capuchin monkeys (Cebus apella). We demonstrate that, lik...
متن کاملSocial disappointment explains chimpanzees' behaviour in the inequity aversion task.
Chimpanzees' refusal of less-preferred food when an experimenter has previously provided preferred food to a conspecific has been taken as evidence for a sense of fairness. Here, we present a novel hypothesis-the social disappointment hypothesis-according to which food refusals express chimpanzees' disappointment in the human experimenter for not rewarding them as well as they could have. We te...
متن کاملPersonality influences responses to inequity and contrast in chimpanzees.
Several species besides humans respond negatively to inequity (i.e. receiving a less preferred outcome as compared to a social partner). Among primates, the taxon for which inequity responses have been most comprehensively studied, there are large individual differences in responses that have, thus far, not been well explained by demographic features such as sex, rank and age. Recent evidence s...
متن کاملAre apes really inequity averse?
Brosnan et al. (Brosnan, S. F. Schiff, H. C. & de Waal, F. B. M. 2005 Tolerance for inequity may increase with social closeness in chimpanzees. Proc. R. Soc. B272, 253-258) found that chimpanzees showed increased levels of rejection for less-preferred food when competitors received better food than themselves and postulated as an explanation inequity aversion. In the present study, we extended ...
متن کاملBonds smooth conflicts
Humans tend to respond differently between each other to rewards being dished out unfairly in different social groups, yet little is known about the potential for such variation in other species. A new study has examined responses to such inequity in several groups of chimpanzees (Pan troglodytes). The study, by Sarah Brosnan, Hillary Schiff and Frans de Waal, at the Yerkes National Primate Cen...
