人类做什么事情的时候,总是容易跟着权威人物走,没想到猩猩社会也这样。美国研究人员准备了两个形状不同的容器,然后从两群黑猩猩中选出两只地位较高的雌猩猩,通过奖励苹果、香蕉等食物,训练它们拣起标牌扔到其中一个容器里。其他黑猩猩发现受过训练的雌黑猩猩将标牌扔到某个容器后会得到食物,纷纷效仿。 When human beings do something, they are always easy to follow authority figures and did not expect the orangutan community to do the same. US researchers prepared two containers of different shapes and then selected two higher-priced female orangutans from two groups of chimpanzees and trained them to pick up signs and place them in a container by rewarding them for food such as apples and bananas. Other chimpanzees find that trained chimpanzees will get food after they have tossed the sign into a container.
