Abstract

This is the first study to explore genetic and environmental contributions to individual differences in emotion regulation in toddlers, and the first to examine the genetic and environmental etiology underlying the association between emotion regulation and working memory. In a sample of 304 same-sex twin pairs (140 MZ, 164 DZ) at age 3, emotion regulation was assessed using the Behavior Rating Scale of the Bayley Scales of Infant Development (BRS; Bayley, 1993), and working memory was measured by the visually cued recall (VCR) task (Zelazo, Jacques, Burack, & Frye, 2002) and several memory tasks from the Mental Scale of the BSID. Based on model-fitting analyses, both emotion regulation and working memory were significantly influenced by genetic and nonshared environmental factors. Shared environmental effects were significant for working memory, but not for emotion regulation. Only genetic factors significantly contributed to the covariation between emotion regulation and working memory.

摘要

这是第一项探索幼儿情绪调节个体差异的遗传和环境贡献的研究,也是第一项研究情绪调节与工作记忆之间关联的遗传和环境病因的研究。在一项 304 对同性别双胞胎(140 对 MZ,164 对 DZ)的样本中,在 3 岁时使用贝利婴幼儿发展量表的行为评定量表(BRS;Bayley,1993)评估情绪调节,使用视觉提示回忆(VCR)任务(Zelazo,Jacques,Burack 和 Frye,2002)以及 BSID 心理量表中的几个记忆任务测量工作记忆。基于模型拟合分析,情绪调节和工作记忆均受到遗传和非共享环境因素的显著影响。共享环境对工作记忆有显著影响,但对情绪调节没有影响。只有遗传因素对情绪调节和工作记忆之间的协变有显著贡献。
