摘要
自尊是个体差异的一个重要方面,迄今已有许多研究从行为遗传学角度探讨自尊个体差异的来源。通过梳理现有关于自尊的双生子研究,发现:1)自尊有中等的遗传度,其个体差异来自遗传和非共享环境;2)遗传对自尊的稳定性有较大作用;3)自尊与认知、情感的联系主要源自共同的遗传基础。总之,遗传对自尊具有重要影响。未来双生子研究可拓展到自尊波动性、内隐自尊等领域,并考虑极端人群的遗传特异性和文化对自尊遗传性的影响。
As an important aspect of individual difference, self-esteem has attracted increasing attentions from behavioral genetic scientists. In this paper, we reviewed twin studies on self-esteem and found that： 1） self-esteem is moderately heritable, though non-shared environmental factors also make a difference; 2） the stability of self-esteem is largely genetically determined; 3） the associations between self-esteem and cognition as well as affect are mainly genetically caused. Together, genetic influences on self-esteem are essential. Future twin study may pay more attention to the heritability of self-esteem fluctuation and implicit self-esteem on one hand, and the specificity of people from extreme sub-groups and those from different cultures on the other hand.
