一項最新研究發(fā)現(xiàn),,對個體而言,生活中的幸福感很大程度上會受到基因組合的影響,。相關(guān)論文發(fā)表在3月的《心理科學(xué)》(Psychological Science)上,。
進行該項研究的是英國愛丁堡大學(xué)和澳大利亞昆士蘭醫(yī)學(xué)研究所的心理學(xué)家。他們發(fā)現(xiàn),,一個人的個性品質(zhì)部分決定著他(她)的幸福感,,而這兩者很大程度上都是可以遺傳和繼承的。
利用心理學(xué)上測定個性和人格的五因素模型(Five-Factor Model),,研究人員發(fā)現(xiàn),,那些不過度憂慮、好交際且耿直盡責(zé)的人往往更加幸福,。他們表示,,這種個性組合在有壞事情發(fā)生時能夠成為良好的“緩沖器”。
通過分析900對雙胞胎的個性和幸福感數(shù)據(jù),,結(jié)合基因研究,,研究人員發(fā)現(xiàn),一些導(dǎo)致特定個性特征的人類共有基因能讓人天生就更傾向于擁有幸福感,。
這一結(jié)果表明,,那些恰好擁有合理個性基因組合的幸運兒具有幸福感的“蓄水池”,即使當(dāng)他們有壓力時,,幸福感也會召之即來,。
不過,研究人員提醒,,盡管最新研究發(fā)現(xiàn)幸福感植根于我們的基因中,,但仍有大約50%的幸福感差異是受個體的外部因素比如人際關(guān)系、健康和事業(yè)狀況影響的,。
論文第一作者,、愛丁堡大學(xué)的Alexander Weiss說,“對幸福的追求是人類欲望的一個核心,。盡管它受到廣泛的外部影響,,但我們發(fā)現(xiàn),,幸福感具有可遺傳的成分。而通過個性的遺傳結(jié)構(gòu)體系可以充分地解釋這一問題,。”(科學(xué)網(wǎng) 任霄鵬/編譯)

Happiness Is a Personal(ity) Thing: The Genetics of Personality and Well-Being in a Representative Sample
Alexander Weiss, Timothy C. Bates, and Michelle Luciano
Abstract
ABSTRACT—Subjective well-being is known to be related to personality traits. However, to date, nobody has examined whether personality and subjective well-being share a common genetic structure. We used a representative sample of 973 twin pairs to test the hypothesis that heritable differences in subjective well-being are entirely accounted for by the genetic architecture of the Five-Factor Model's personality domains. Results supported this model. Subjective well-being was accounted for by unique genetic influences from Neuroticism, Extraversion, and Conscientiousness, and by a common genetic factor that influenced all five personality domains in the directions of low Neuroticism and high Extraversion, Openness, Agreeableness, and Conscientiousness. These findings indicate that subjective well-being is linked to personality by common genes and that personality may form an "affective reserve" relevant to set-point maintenance and changes in set point over time.
