    A Proximate Perspective on Reciprocal Altruism.Sarah F. Brosnan & Frans B. M. de Waal - 2002 - Human Nature 13 (1):129-152.
    The study of reciprocal altruism, or the exchange of goods and services between individuals, requires attention to both evolutionary explanations and proximate mechanisms. Evolutionary explanations have been debated at length, but far less is known about the proximate mechanisms of reciprocity. Our own research has focused on the immediate causes and contingencies underlying services such as food sharing, grooming, and cooperation in brown capuchin monkeys and chimpanzees. Employing both observational and experimental techniques, we have come to distinguish three types of (...)

    A Cross-Species Perspective on the Selfishness Axiom.Sarah F. Brosnan & Frans B. M. de Waal - 2005 - Behavioral and Brain Sciences 28 (6):818-818.
    Henrich et al. describe an innovative research program investigating cross-cultural differences in the selfishness axiom (in economic games) in humans, yet humans are not the only species to show such variation. Chimpanzees and capuchin monkeys show signs of deviating from the standard self-interest paradigm in experimental settings by refusing to take foods that are less valuable than those earned by conspecifics, indicating that they, too, may pay attention to relative gains. However, it is less clear whether these species also show (...)
