This paper examined children's fearful, sad, and angry reactivity to interparental conflict as mediators of associations between their exposure to interparental aggression and physiological functioning.
Participants included 200 toddlers and their mothers. Assessments of interparental aggression and children's emotional reactivity were derived from maternal surveys and a semi-structured interview. Cortisol levels and cardiac indices of sympathetic nervous system (SNS) and parasympathetic nervous system (PNS) activity were used to assess toddler physiological functioning.
Results indicated that toddler exposure to interparental aggression was associated with greater cortisol levels and PNS activity and diminished SNS activity. Toddler angry emotional reactivity mediated associations between interparental aggression and cortisol and PNS functioning. Fearful emotional reactivity was a mediator of the link between interparental aggression and SNS functioning.
The results are interpreted within conceptualizations of how exposure and reactivity to family risk organize individual differences in physiological functioning.
本研究考察了儿童对父母冲突的恐惧、悲伤和愤怒反应，以探讨其对父母间攻击行为与生理功能之间关系的中介作用。
参与者包括 200 名幼儿及其母亲。父母间攻击行为和儿童情绪反应性的评估来自于母亲的问卷调查和半结构化访谈。皮质醇水平和自主神经系统（SNS）和副交感神经系统（PNS）活动的心脏指数用于评估幼儿的生理功能。
结果表明，幼儿暴露于父母间攻击行为与更高的皮质醇水平和 PNS 活动以及更低的 SNS 活动相关。幼儿愤怒的情绪反应性中介了父母间攻击行为与皮质醇和 PNS 功能之间的关联。恐惧的情绪反应性是父母间攻击行为与 SNS 功能之间联系的中介。
这些结果是根据对家庭风险的暴露和反应如何组织个体差异的生理功能的概念来解释的。
