尽管人们对识别认知过程的神经关联非常感兴趣，但对幼儿的研究却很少。事件相关电位(ERP)中的N2被认为是冲突监控的指标，并被认为与焦虑的认知和情感风险因素有关。然而，这项研究的大部分是在成年人、青少年和年龄较大的儿童中进行的，但不是在年幼的儿童中进行的。为了解决这一差距，目前的研究调查了26名4-8岁的儿童，他们在连续记录脑电的同时完成了一项线索侧翼任务。我们评估了在这组幼儿中是否可以检测到n2，并检查了n2与反映情感风险的因素(例如，减少的执行注意力、气质的努力控制和气质的暴躁)之间的关联。我们记录了一种氮气效应(对不一致侧翼和一致侧翼的更大的氮气幅度)，但仅在6岁以上的儿童中出现。氮气效应的增加与效率较低的执行注意力和较低的气质努力控制有关。我们讨论了这些发现的含义，并考虑它们如何为未来关于焦虑的认知和情感风险因素的生物标记物的研究提供信息。
Although there is great interest in identifying the neural correlates of cognitive processes that create risk for psychopathology, there is a paucity of research in young children. One event-related potential (ERP), the N2, is thought to index conflict monitoring and has been linked cognitive and affective risk factors for anxiety. Most of this research, however, has been conducted with adults, adolescents, and older children, but not with younger children. To address this gap, the current study examined 26 4–8-year-olds, who completed a cued flanker task while EEG was continuously recorded. We assessed whether the N2 was detectable in this group of young children and examined associations between the N2 and factors reflecting affective risk (e.g., reduced executive attention, temperamental effortful control, and temperamental surgency). We documented an N2 effect (greater N2 amplitude to incongruent versus congruent flankers), but only in children older than 6 years of age. Increases in the N2 effect were associated with less efficient executive attention and lower temperamental effortful control. We discuss the implications of these findings and consider how they may inform future studies on biomarkers for cognitive and affective risk factors for anxiety.
