Emotional conflict adaptation is an important process of cognitive control in human behavioral regulation. The face-word Stroop task and the emotional Simon task were employed to explore the correlation between fluid intelligence and neural processes of emotional conflict adaptation using event-related potential (ERP) techniques. Thirty-two intellectually average children (mean age of 10.72 years) and thirty-four intellectually gifted children (mean age of 10.86 years) participated in the present study. The behavioral results indicated that both intellectually gifted and average children showed reliable emotional conflict adaptation effects (CAEs) on reaction times (RTs) and error rates. However, the two IQ groups differed in the magnitude of error rates during emotional conflict adaptation. The electrophysiological results further revealed that the IQ differences in emotional conflict adaptation were mainly associated with emotional conflict detection processes as demonstrated by the frontal N2-CAE values. The two IQ groups did not differ in early P3 or late P3 responses during emotional conflict resolution processes. The gifted and average children showed different patterns during cognitive control processes when facing emotional Simon conflicts and emotional Stroop conflicts. The current study emphasizes the importance of frontal function during cognitive control of emotional information from the perspective of individual differences.
情绪冲突适应是人类行为调节中认知控制的重要过程。本研究采用面孔-词斯特鲁普任务和情绪 Simon 任务，结合事件相关电位（ERP）技术，探讨了流体智力与情绪冲突适应的神经加工过程之间的关系。共有 32 名智力中等的儿童（平均年龄 10.72 岁）和 34 名智力超常的儿童（平均年龄 10.86 岁）参与了本研究。行为结果表明，智力超常和中等的儿童在反应时（RT）和错误率上均表现出可靠的情绪冲突适应效应（CAE）。然而，这两个智商组在情绪冲突适应过程中的错误率大小上存在差异。电生理结果进一步表明，情绪冲突适应中的智商差异主要与情绪冲突检测过程有关，这表现在额部 N2-CAE 值上。在情绪冲突解决过程中，两个智商组在早期 P3 和晚期 P3 反应上没有差异。在面对情绪 Simon 冲突和情绪斯特鲁普冲突时，超常儿童和普通儿童在认知控制过程中表现出不同的模式。本研究从个体差异的角度强调了额叶功能在情绪信息认知控制中的重要性。
