침팬지에게 공평함을 느끼는 감각이 있다는 연구결과가 밝혀졌다.
에모리대학의 여크국립영장류연구센터는 침팬지에게 공평함을 느끼는 감각이 있는지 여부를 밝히기 위해 최후통첩 게임을 이용한 연구를 진행하였다.
최후통첩 게임은 한 플레이어가 다른 플레이어에게 보상을 나누자고 제안하고 다른 플레이어가 동의해야만 성립하는 게임이다. 침팬지들이 최후통첩 게임을 할 때 인간과 마찬가지로 공평하게 보상을 나누었다고 연구진은 밝혔다.
이때까지 공평함을 느끼는 감각은 인간에게만 있는 특성이라고 알려졌다. 이번 연구는 영장류가 공평함을 느낄 수 있다는 것을 증명하는 최초의 연구이다.
이번 연구결과는 침팬지를 비롯한 영장류가 공평함 이외에도 인간이 가지고 있는 성향 및 특성을 지닐 수 있다는 가능성을 열어주었다. (코리아헤럴드)

Apes have a sense of fairness: report
From news reports
A study has found that Chimpanzees have a sense of fairness, which had long been regarded as unique to humans.
Researchers at the Yerks National Primate Research Center in Emory University conducted research to find out if chimpanzees have a human-like sense of equality.
The researchers tested six apes on the Ultimate Game. In the game, two players are rewarded with a small prize only if one individual agrees to split the prize. Adult humans most often offer a suggestion that equally benefits both participants.
The chimpanzees also suggested fair options, according to the research project. When they were given two differently colored tokens -- one equally rewarding both players and another favoring the individual making the choice, chimpanzees chose the token that equally rewards both players. When tested on 20 human children, the Ultimate Game also produced a similar result.
The study opens the possibility for further exploration into human-like traits of apes. An early online edition of this finding is available on the Proceedings of the National Academy of Sciences website.
