Extensive research has investigated links between individual differences in youths' autonomic nervous system (ANS) functioning and psychological outcomes related to emotion regulation, yet little of this research has examined developmental change. The study tested whether individual differences in youths' tonic and stress-induced ANS functioning, assessed at age 14, and changes in ANS functioning from age 14 to 16 predicted corresponding changes in youths' behavioral warmth, as displayed during videotaped mother-child conflict interactions conducted at age 14 and 16. Increased behavioral warmth was predicted by increased baseline respiratory sinus arrhythmia (RSA), increased SCL stress reactivity, decreased RSA stress reactivity (i.e., greater vagal suppression), and decreased baseline SCL. There was also an interaction between RSA stress reactivity at age 14 and changes in maternal warmth from age 14 to 16, such that increased maternal warmth was only associated with increased adolescent warmth for adolescents with lower RSA stress reactivity at age 14.
大量研究调查了青少年自主神经系统（ANS）功能的个体差异与情绪调节相关的心理结果之间的联系，但很少有研究探讨发展变化。该研究检验了青少年在 14 岁时的自主神经功能的静息和应激诱导的个体差异，以及从 14 岁到 16 岁期间自主神经功能的变化是否预测了青少年在 14 岁和 16 岁进行的录像母子冲突互动中表现出的相应行为温暖度的变化。较高的行为温暖度与基线呼吸窦性心律失常（RSA）增加、SCL 应激反应性增加、RSA 应激反应性降低（即迷走神经抑制增加）和基线 SCL 降低有关。14 岁时的 RSA 应激反应性与 14 岁到 16 岁期间的母亲温暖度变化之间也存在交互作用，对于 14 岁时 RSA 应激反应性较低的青少年，母亲温暖度的增加仅与青少年温暖度的增加有关。
