Previous research has shown that caregiver protective behavior may exacerbate toddler distress in specific contexts. The current study sought to extend this work to examine associations between these variables and toddler cortisol reactivity. Ninety-three 24-month-old toddlers were observed across six novel contexts designed to elicit distress. Toddlers were asked to give saliva samples at the beginning and end of the laboratory procedure. Toddler sadness, toddler fear, and caregiver protective behavior were coded. Results indicate that caregiver protective behavior accounted for the association between toddler sadness and cortisol reactivity where higher levels of protective behavior were associated with higher cortisol reactivity. The current study showed that caregiver protective behavior, which functions to prevent a child from interacting with a novel stimulus, is an important mechanism to consider when understanding toddler stress responses during novel contexts.
先前的研究表明，照顾者的保护行为可能会在特定情境中加剧幼儿的痛苦。当前的研究试图扩展这项工作，以检验这些变量与幼儿皮质醇反应性之间的关联。研究人员在六个旨在引发痛苦的新情境中观察了93名24个月大的幼儿。在实验室程序开始和结束时，要求幼儿提供唾液样本。对幼儿的悲伤、恐惧以及照顾者的保护行为进行了编码。结果表明，照顾者的保护行为解释了幼儿悲伤与皮质醇反应性之间的关联，即较高水平的保护行为与较高的皮质醇反应性相关。当前的研究表明，照顾者的保护行为旨在防止儿童与新刺激物互动，这是理解幼儿在新情境中的应激反应时需要考虑的一个重要机制。
