A Hypothesis Of The Co-Evolution Of Cooperation And Inequity, Sarah F. Brosnan
A Hypothesis Of The Co-Evolution Of Cooperation And Inequity, Sarah F. Brosnan
Psychology Faculty Publications
Recent evidence demonstrates that humans are not the only species to respond negatively to inequitable outcomes which are to their disadvantage. Several species respond negatively if they subsequently receive a less good reward than a social partner for completing the same task. While these studies suggest that the negative response to inequity is not a uniquely human behavior, they do not provide a functional explanation for the emergence of these responses due to similar characteristics among these species. However, emerging data support the hypothesis that an aversion to inequity is a mechanism to promote successful long-term cooperative relationships amongst non-kin. …

There is great interest in the evolution of economic behavior. In typical studies, species are asked to play one of a series of economic games, derived from game theory, and their responses are compared. The advantage of this approach is the relative level of consistency and control that emerges from the games themselves; however in the typical experiment, procedures and conditions differ widely, particularly between humans and other species. Thus, in the current study we investigated how three primate species, capuchin monkeys, chimpanzees, and humans, played the Assurance (or Stag Hunt) Game using procedures which were, to the best of …
An Evolutionary Perspective On Morality, Sarah F. Brosnan
An Evolutionary Perspective On Morality, Sarah F. Brosnan
Psychology Faculty Publications
Moral behavior and concern for others are sometimes argued to set humans apart from other species. However, there is some evidence that humans are not the only animal species to possess these characteristics. Work from behavioral biology and neuroscience has indicated that some of these traits are present in other species, including other primates. Studying these behaviors in other species can inform us about the evolutionary trajectory of morality, either helping understand how the behaviors evolved and which environmental characteristics were critical for their emergence. While this evolutionary approach to human behavior is not always well received, a brief historical …
