Internalizing problems increase substantially during late childhood and early adolescence, which are known to be associated with elevated perceived stress as children transition into adolescence. One risk factor that may moderate the stress-symptom association is reward processing. While neurophysiological research in this field has focused on the reward positivity component (RewP) elicited during reward processing, little work has examined the reward feedback-elicited late positive potential (LPP) and its association with internalizing psychopathology. The present study examined the moderating roles of the RewP and feedback-elicited LPP in the relationship between perceived stress and internalizing symptoms in late childhood. A community sample of 115 nine-to-12-year-old children (66 girls, Mean age = 11.00 years, SD = 1.16) completed an EEG version of the reward feedback paradigm, the Doors task, and completed questionnaires on perceived stress and internalizing symptoms. A principal component analysis revealed three temporo-spatial factors that were temporally and spatially analogous to the RewP, anterior LPP, and posterior LPP, respectively. As expected, an enlarged RewP was found towards the win condition compared to the loss condition. We also observed a potentiated LPP towards loss relative to win feedback, which may reflect the evaluation and reappraisal processes following unsuccessful performance (i.e., loss). We did not, however, find significant moderating effects of any ERP components on the stress-symptom association. Our study was first to isolate the feedback-elicited LPP in a reward processing paradigm in children and provide initial evidence on the modulation of the ERP component by task conditions. Future research is warranted to further explore the functional significance of the reward feedback-elicited LPP in association with perceived stress and internalizing psychopathology in youths.
内化问题在童年晚期和青春期早期显著增加，众所周知，随着儿童向青少年过渡，这些问题与感知压力升高有关。一个可能调节压力与症状关联的风险因素是奖励处理。虽然该领域的神经生理学研究主要集中在奖励处理过程中引发的奖励正性成分（RewP），但很少有研究考察奖励反馈引发的晚期正性电位（LPP）及其与内化心理病理学的关联。本研究考察了RewP和反馈引发的LPP在童年晚期感知压力与内化症状关系中的调节作用。一个由115名9至12岁儿童组成的社区样本（66名女孩，平均年龄 = 11.00岁，标准差 = 1.16）完成了奖励反馈范式的脑电图版本、门任务，并完成了关于感知压力和内化症状的问卷。主成分分析揭示了三个时空因素，它们在时间和空间上分别类似于RewP、前LPP和后LPP。正如预期的那样，与失败条件相比，在胜利条件下发现RewP增大。我们还观察到相对于胜利反馈，失败反馈引发的LPP增强，这可能反映了表现不佳（即失败）后的评估和重新评估过程。然而，我们没有发现任何ERP成分对压力与症状关联有显著的调节作用。我们的研究首次在儿童的奖励处理范式中分离出反馈引发的LPP，并提供了任务条件对ERP成分调节作用的初步证据。未来的研究有必要进一步探索奖励反馈引发的LPP与青少年感知压力和内化心理病理学相关的功能意义。
