近日，研究表明基因可能對(duì)成功的生活起到關(guān)鍵作用,，相關(guān)研究論文刊登在Journal of Personality雜志上,。
新的研究表明基因在形成性格特征如自我控制、決策或社交性中發(fā)揮更大的作用,。
這項(xiàng)超過800對(duì)雙胞胎的研究發(fā)現(xiàn),，基因比一個(gè)人的家庭環(huán)境及周邊地區(qū)對(duì)關(guān)鍵性格的塑造有影響力。
愛丁堡進(jìn)行了該項(xiàng)研究,，大學(xué)心理學(xué)家們認(rèn)為基因影響的性格特征很可能是在一個(gè)人生活中成功與否的關(guān)鍵,。
在這項(xiàng)研究中，50歲及以上的參試者采用了一系列的問題以測(cè)試他們?nèi)绾胃兄约汉退?。問題包括“你受有強(qiáng)烈意見的人的影響嗎,？你失望于你在生活中的成就嗎？
根據(jù)Ryff心理幸福感量表評(píng)估和標(biāo)準(zhǔn)化這些特征后，研究人員測(cè)量了結(jié)果,。
通過跟蹤他們的答案,，研究小組發(fā)現(xiàn)同卵雙胞胎，其DNA是完全相同的,，其可能分享性狀與非異卵雙胞胎相比有明顯差異,。心理學(xué)家說，因?yàn)檫z傳基因聯(lián)系越強(qiáng),，就越有可能具備某些性格特征,。（生物谷：Bioon.com）

Genetic influences on psychological well-being: A nationally representative twin study
Despina Archontaki1, Gary J. Lewis1, Timothy C. Bates1,2,*
OBJECTIVE: Psychological well-being, or eudaimonia, features strongly in theories of human development and thriving. However, the factors of eudaimonia are debated, and their genetic architecture has not been studied in detail.
METHOD: A classical twin design was used to decompose behavioral variance into genetic and environmental components implemented in a multi-group, multivariate structural equation modeling framework. Subjects were 837 pairs of adult US twins from the nationally representative MIDUS II sample. Psychological well-being was measured using the 42-item Ryff Psychological Well-being Scale, which assesses autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance.
RESULTS: Substantial genetic influences were observed on all components of well-being. Attempts to model these 6-factors as reflecting a single common psychological mechanism gave a poor fit to the data. The best-fitting model supported the existence of five distinct genetic effects. Effects of shared-environment were weak and non-significant. Unique-environment effects for all measures were mostly trait specific.
CONCLUSIONS: These results indicate that psychological well-being is underpinned by a general genetic factor influencing self-control, and four underlying biological mechanisms enabling the psychological capabilities of purpose, agency, growth, and positive social relations.
