Comparative Economics: Responses to the Assurance Game in Monkeys, Apes, and Humans Using Equivalent Procedures
نویسندگان
چکیده
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 our ability, the same across species, particularly with respect to training and pre-testing. Our goal was to determine what, if any, differences existed in the ways in which these species made decisions in this game. We hypothesized differences along phylogenetic lines, which we found. However, the species were more similar than might be expected. In particular, humans who played using ‘non-human primate-friendly’ rules did not behave as is typical. Thus, we find evidence for similarity in decision-making processes across the Order Primates. These results indicate that such comparative studies are possible and moreover that in any comparison rating species’ relative abilities, extreme care must be taken in ensuring that one species does not have an advantage over the others due to methodological

متن کاملDifferential Responding by Rhesus Monkeys (Macaca mulatta) and Humans (Homo sapiens) to Variable Outcomes in the Assurance Game
Behavioral flexibility in how one responds to variable partner play can be examined using economic coordination games in which subjects play against a variety of partners and therefore may need to alter their behavior to produce the highest payoff. But how do we study this behavioral flexibility once players have settled on a response? Here, we investigated how responding by rhesus monkeys (Mac...

متن کاملA human reproductive approach to the study of infertility in chimpanzees: An experience at Leon’s Zoological Park, Mexico
Great apes are mammals close to humans in their genetic, behavioral, social and evolutionary characteristics and new genomic information is revolutionizing our understanding of evolution in primates. However, all these species are endangered. While there are many global programs to protect these species, the International Union for Conservation of Nature (IUCN) projects that in a near future th...
