Behavioral inhibition indicates increased risk for development of social anxiety. Recent work has identified a pattern of dysregulated fear (DF), characterized by high fear in low-threat situations, that provides a more precise marker of developmental risk through early childhood. This study tested a new longitudinal sample of children (n = 124) from ages 24 to 48 months. Replicating prior findings, at 24 months, we identified a pattern of fearful behavior across contexts marked by higher fear to putatively low-threat situations. DF was associated with higher parental report of social inhibition at 24, 36, and 48 months. Extending prior findings, we observed differences in cardiac physiology during fear-eliciting situations, suggesting that the neurobiological underpinnings of DF relate to difficulty with regulation.
行为抑制表明发展为社交焦虑症的风险增加。最近的研究确定了一种失调恐惧（DF）模式，其特征是在低威胁情况下出现高度恐惧，这通过幼儿期提供了更精确的发育风险标志物。本研究测试了一个新的纵向儿童样本（n=124），年龄为 24 至 48 个月。复制先前的发现，在 24 个月时，我们在整个环境中发现了一种以对假定的低威胁情况表现出更高恐惧为特征的恐惧行为模式。DF 与 24、36 和 48 个月时父母报告的社交抑制呈正相关。扩展先前的发现，我们观察到在引起恐惧的情况下心脏生理机能的差异，这表明 DF 的神经生物学基础与调节困难有关。
