成人的情绪调节可能是通过额叶皮质活动来调节注意力，以应对具有挑战性的情绪。我们研究了情绪状态下的事件相关电位，以评估4-6岁儿童情绪调节皮层机制的标准化模式和个体差异。在进行/不进行任务时，孩子们观看了愤怒、中立和高兴的面孔的图片。愤怒的面孔产生最大的(前向中央)氮气波幅和最快的氮气潜伏期，而快乐的面孔产生最小的波幅和最慢的潜伏期。在GO状态下，额叶电极对愤怒的面孔显示出更大的N2S。对于愤怒的面孔，P3b也是最大的。越害怕的儿童对愤怒的面孔表现出更快的N2S潜伏期。这些结果是根据调节焦虑和处理情绪信息的早期发展机制来解释的。
Emotion regulation in adults may be mediated by frontal cortical activities that adjust attention in response to challenging emotions. We examined event-related potentials across emotional conditions to assess normative patterns and individual differences in cortical mechanisms of emotion regulation in 4-6-year-olds. The children viewed pictures of angry, neutral, and happy faces during a Go/No-go task. Angry faces generated the greatest (frontocentral) N2 amplitudes and fastest N2 latencies, and happy faces produced the smallest amplitudes and slowest latencies. Frontal electrodes showed larger N2s to angry faces in the Go condition. The P3b was also largest for angry faces. More fearful children showed faster latency N2s to angry faces. These results are interpreted in terms of early-developing mechanisms for regulating anxiety and processing emotional information.
