In their study,  published in the Sept. 18 <em>Nature,<\/em> Sarah Brosnan and Frans de Waal taught  brown capuchin monkeys, a social primate, to exchange tokens for food.  Cucumber would normally be considered an acceptable treat, and the  capuchins were happy to exchange a token for a piece. But if a monkey  saw another monkey getting a grape &#8212; a more-favored food &#8212; in  exchange, an interesting thing happened. Some would then refuse to hand  over a token at all; others would refuse the cucumber, and some would  take the cucumber, but refuse to eat it. The monkeys also appeared to  get upset if another monkey received a treat for doing nothing at all.  While the researchers acknowledge that their data can&#8217;t give the precise  motivation for why the capuchins reacted as they did, they think that  just like humans, the monkeys may hold &#8220;emotionally charged expectations  about reward distribution and social exchange.&#8221; According to the  authors, the capuchins&#8217; reactions also &#8220;support an early evolutionary  origin of inequity aversion.&#8221; <\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 9\/23\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Just like humans, capuchin monkeys have been found to have a sense of fairness, say researchers from the Yerkes National Primate Research Center of Emory University in Atlanta.
