The way individuals process socio-affective information is thought to impact their responses to social interactions, but research testing the relation between these processes is scarce, particularly among children. This study examined if children's attention to socio-affective stimuli was associated with their autonomic nervous system (ANS) reactivity during parent-child interactions. Children's sustained attention to facial expressions of emotion (afraid, happy, sad) was indexed using the late positive potential (LPP) event-related potential (ERP) component during a computer-based task. To measure ANS reactivity, children's respiratory sinus arrhythmia (RSA) was assessed at baseline and during positive and negative parent-child discussions. Enhanced LPP amplitudes in response to all emotional facial expressions, reflecting greater sustained attention to socio-affective stimuli, were associated with increased RSA reactivity during parent-child discussions. These results show correspondence between two psychophysiological substrates of emotion processing in healthy children and highlight how these systems may be synergistic forces contributing to emotion reactivity.
人们处理社会情感信息的方式被认为会影响他们对社交互动的反应，但检验这些过程之间关系的研究很少，尤其是在儿童中。本研究考察了在亲子互动过程中，儿童对社会情感刺激的注意力是否与他们的自主神经系统（ANS）反应性相关。在一项基于计算机的任务中，使用晚期正电位（LPP）事件相关电位（ERP）成分来衡量儿童对情绪面部表情（恐惧、快乐、悲伤）的持续注意力。为了测量ANS反应性，在基线以及积极和消极的亲子讨论期间评估儿童的呼吸性窦性心律不齐（RSA）。对所有情绪面部表情的反应中增强的LPP波幅，反映出对社会情感刺激的持续注意力增强，这与亲子讨论期间RSA反应性增加有关。这些结果表明了健康儿童情绪处理的两种心理生理基础之间的对应关系，并突出了这些系统如何可能是促成情绪反应性的协同力量。
