A study suggests that our more primitive primate relatives are capable of self-awareness.

A study of monkeys trained to play computer games has shown it is not just humans who feel self-doubt and uncertainty, the BBC reported.

US scientists found that macaques often "pass" rather than risk choosing the wrong answer in brainteaser tasks.

Awareness of our own thinking was believed to be a uniquely human trait. But the study, presented at the AAAS meeting in Washington DC, suggests that our more primitive primate relatives are capable of self-awareness. （点击BBC网站查看原文）

猴子似人类会自我怀疑

       据英国广播公司报道，研究表明，在训练猴子玩电脑游戏时，它表现出同人类相似的特性，即自我怀疑和犹豫不定。

       美国科学家研究发现，猕猴在遇到难题时会选择“过”（放弃这一题）而不是冒险选择错误的答案。

       我们原先认为这一特性是人类特有的。但在美国科学促进学会会议上提交的这份研究表明，与我们人类相似的灵长类动物也具备这种自我意识。
