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.

根據(jù)一項(xiàng)于周一公布的美國(guó)調(diào)查顯示，眾所周知擁有某種基因的人比其他人更為善良和富于同情心，而陌生人能立即分辨這類人的不同。

 

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

俄勒岡州立大學(xué)的科學(xué)家們?yōu)?3對(duì)夫妻設(shè)計(jì)了一個(gè)錄像實(shí)驗(yàn)。這些實(shí)驗(yàn)者的基因類型只有研究人員知道，而實(shí)驗(yàn)觀察者并未掌握。

 

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.

夫妻中的一方被要求和對(duì)方講述自己生活中一段艱難經(jīng)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。

 

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.

11月14日出版的美國(guó)國(guó)家科學(xué)院院刊公布了這一實(shí)驗(yàn)發(fā)現(xiàn)：在大多數(shù)的情況下，實(shí)驗(yàn)觀察者能分辨出擁有“善良基因”的聆聽者和沒(méi)有這一基因的聆聽者。

 

"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.

該研究論文的主要作者、多倫多大學(xué)的博士后研究員亞歷山大-柯崗說(shuō)：“我們的發(fā)現(xiàn)結(jié)果表明即使輕微的基因變異也可能會(huì)對(duì)個(gè)人的行為造成具體影響。而且這些行為上的偏差很快就能被其他人注意到。”
