认知-情感自我参照处理的实质性变化发生在青春期。我们研究了109名12-17岁健康男女青少年自我评价的行为和ERP相关。参与者完成了抑郁症状和青春期的评估以及自我参考编码任务，同时收集了128通道高密度EEG数据。抑郁症状的严重程度与消极词汇的增加和反应时间的延长有关。在一个极端的组分析，负评价偏差子样本（n = 28）显示正面P2振幅下降，积极和消极的词刺激，反映减少早期注意力处理和情绪的显着性。与积极评价偏差子样本（n = 27）相比，消极评价偏差子样本显示LPP减少，积极的话，但不是消极的话，这表明衰减的持续处理积极的自我相关刺激。研究结果进行了讨论，在神经过程中与ERPs在消极与积极的自我评价的偏见，和发展的影响。
Substantial changes in cognitive-affective self-referential processing occur during adolescence. We studied the behavioral and ERP correlates of self-evaluation in healthy male and female adolescents aged 12-17 (N = 109). Participants completed assessments of depression symptoms and puberty as well as a self-referential encoding task while 128-channel high-density EEG data were collected. Depression symptom severity was associated with increased endorsement of negative words and longer reaction times. In an extreme group analysis, a negative appraisal-bias subsample (n = 28) displayed decreased frontal P2 amplitudes to both positive and negative word stimuli, reflecting reduced early attentional processing and emotional salience. Compared to the positive appraisal-bias subsample (n = 27), the negative appraisal-bias subsample showed reduced LPP to positive words but not negative words, suggesting attenuated sustained processing of positive self-relevant stimuli. Findings are discussed in terms of neural processes associated with ERPs during negative versus positive self-appraisal bias, and developmental implications.
