摘　　要：“遗传与环境”的争论一直是创造力研究的核心问题,但目前对于环境以及遗传与环境交互作用对创造力影响的分子生物机制还未有研究涉及。近年来,随着表观遗传学的兴起,揭示影响心理行为的表观遗传机制现已成为心理学研究的热点。作为环境与基因组之间的纽带,表观遗传学研究为揭示环境以及遗传与环境交互作用对创造力影响的分子生物机制提供了机遇。本研究以多巴胺相关基因、家庭环境以及两者对于创造力的交互作用为切入点,对影响创造力的表观遗传机制进行考察,并在此基础之上,对环境以及遗传与环境交互作用对创造力影响的分子生物机制进行探索。具体研究内容包括:(1)通过对多巴胺相关基因甲基化模式与创造力关系的系统考察,筛选出甲基化模式与创造力有关的基因;(2)对筛选出的基因,进一步考察其甲基化模式在家庭环境及其遗传多态性与家庭环境交互作用对创造力影响中的中介作用。本研究有助于揭示创造力的表观遗传机制,深化关于遗传与环境对创造力影响的作用机制的理解。Although the debate over“nature versus nurture”has been an intense focus of creativity research and great efforts have been made to identify genes and environmental factors that contribute to creativity,the molecular biological mechanisms by which environment and gene-environment interaction may influence creativity are still unknown.Recently,with the development of epigenetic studies,identification of the epigenetic basis of complex traits and behaviors has been one of the leading issues in psychological research.As a potential mediator between environment and genome,the epigenetic approach provides an opportunity to reveal how the complex interactions of genes,epigenetics and environment give rise to individual differences in creativity.Based on this notion,by investigating the relationship between methylation of dopamine-related genes,family environment and creativity,the present study aims to reveal the epigenetic basis of creativity and the molecular biological mechanisms by which environment and gene-environment interaction may influence creativity.To this purpose,the present study employs a two-stage design.Stage 1 is designed to systematically investigate the association between methylation of dopamine-related genes and creativity,and aims to identify the gene whose methylation is associated with creativity.Stage 2 focuses on the identified gene whose methylation is associated with creativity,and is designed to investigate the relationship between family environment,genotypes,methylation and creativity.It is expected that findings of the present study would help to demonstrate the epigenetic basis of creativity and to provide important insight into the mechanisms by which genes and environmental factors interplay with each other to influence creativity.
