摘　　要：研究探讨了亲子关系与CLOCK基因rs1801260多态性对学前儿童亲社会行为的交互影响及性别的调节作用。以694名学前儿童(M_(年龄)=5.06岁,SD=0.87)及其父母为测试对象,收集儿童的唾液样本进行基因分型,由儿童父母填写亲子关系和儿童亲社会行为量表。研究结果发现,亲子亲密与亲子冲突对亲社会行为的主效应显著。亲子冲突、CLOCK基因rs1801260多态性和性别三重交互影响儿童的亲社会行为,即与携带C等位基因的男孩相比,携带TT基因型的男孩在低亲子冲突下会表现出更多的亲社会行为,在高亲子冲突下则表现出更少的亲社会行为。但亲子冲突与CLOCK基因rs1801260多态性对女孩亲社会行为的交互作用不显著。研究结果为深入理解学前儿童亲社会行为形成的基因-环境交互作用机制提供了证据。The present study examined whether parent-child relationships interact with the CLOCK rs1801260 polymorphism to contribute to children's prosocial behaviors.The saliva of 694 preschoolers(Mage=5.06,SD=0.87)was extracted to genotype the CL0CK rs1801260 polymorphism,and children's parents were invited to complete questionnaires to assess parent-child relationships and children's prosocial behaviors.After controlling for age and family socioeconomic status,the results indicated that parent-child closeness was positively while parent-child conflict was negatively related to preschoolers'prosocial behaviors,and the significant interaction effect of parentchild conflict and the CLOCK rs1801260 polymorphism was found in boys but not girls.Compared with C allele carriers,boys with TT genotype developed more prosocial behaviors under the condition of lower parent-child conflict while fewer prosocial behaviors under the condition of higher parent-child conflict.The findings of the present study expand our knowledge about the G×E underpinnings of children's prosocial behaviors.
