陌生人能認出“善良”基因

People with a certain gene trait are known to be More kind and caring than people without it, and strangers can quickly tell the difference, according to US research published on Monday.

Scientists at Oregon State University devised an experiment in which 23 couples, whose genotypes were known to researchers but not observers, were filmed.

One member of the couple was asked to tell the other about a time of suffering in his or her life. Observers were asked to watch the listener for 20 seconds, with the sound turned off.

In most cases, the observers were able to tell which of the listeners had the "kindness gene" and which ones did not, said the findings in the Proceedings of the NationAl Academy of Sciences edition of November 14.

"Our findings suggest even slight genetic variation may have tangible impact on people's behavior, and that these behavioral differences are quickly noticed by others," said lead author Aleksandr Kogan, a postdoctoral fellow at the University of Toronto.據法新社11月15日報道，根據一項於週一公佈的美國調查顯示，衆所周知擁有某種基因的人比其他人更爲善良和富於同情心，而陌生人能立即分辨這類人的不同。

俄勒岡州立大學的科學家們爲23對夫妻設計了一個錄像實驗。這些實驗者的基因類型只有研究人員知道，而實驗觀察者並未掌握。

夫妻中的一方被要求和對方講述自己生活中一段艱難經歷，而觀察者則被要求在消音的條件下觀察聆聽的一方20秒鐘。

11月14日出版的美國國家科學院院刊公佈了這一實驗發現：在大多數的情況下，實驗觀察者能分辨出擁有“善良基因”的聆聽者和沒有這一基因的聆聽者。

該研究論文的主要作者、多倫多大學的博士後研究員亞歷山大-柯崗說：“我們的發現結果表明即使輕微的基因變異也可能會對個人的行爲造成具體影響。而且這些行爲上的偏差很快就能被其他人注意到。”
