Emotion regulation is a critical component of healthy development, yet few studies examine neural correlates of emotion regulation in childhood. In the present study, we assessed whether children's neurophysiological responses to salient and socially significant emotional distracters-emotional faces-were related to broader emotion regulation capacities. Emotion regulation was measured as attention performance following emotional distracters and as maternal report of child emotional dysregulation. Electroencephalography was recorded while participants (15 children aged 5-9) performed an attention task. Scalp-recorded event related potentials (ERPs) were time-locked to emotional distracters (fearful, sad, and neutral faces) and reflected a range of rapid attentional and face processing operations (P1, N1, N170, and Nc). P1 latencies were faster whereas N1 amplitudes were reduced to fearful compared to sad faces. Larger P1 and Nc amplitudes to fearful and sad faces were correlated with more effective emotion regulation. Results are discussed in terms of mechanisms in emotion regulation and the use of ERPs to detect early risk for psychopathology and inform intervention efforts.
情绪调节是健康发展的关键组成部分,但很少有研究考察儿童期情绪调节的神经关联。在本研究中,我们评估了儿童对显著且具有社会意义的情绪干扰物——情绪面孔——的神经生理反应是否与更广泛的情绪调节能力相关。情绪调节通过情绪干扰物后的注意力表现以及母亲对孩子情绪失调的报告来衡量。在参与者(15名5至9岁的儿童)执行注意力任务时记录脑电图。头皮记录的事件相关电位(ERP)与情绪干扰物(恐惧、悲伤和中性面孔)进行时间锁定,并反映了一系列快速的注意力和面孔加工操作(P1、N1、N170和Nc)。与悲伤面孔相比,恐惧面孔的P1潜伏期更快,而N1波幅降低。对恐惧和悲伤面孔更大的P1和Nc波幅与更有效的情绪调节相关。我们从情绪调节机制以及使用ERP检测精神病理学早期风险并为干预措施提供信息的角度讨论了结果。
