我们检查了事件相关脑电图（EEG）振荡，包括事件相关频谱扰动（ERSP）和试验间一致性（ITC），以比较10-12岁（n = 42），13-14岁（n = 34）和15-17岁（n = 32）的儿童在基于机会的奖励与非奖励任务中的反馈处理。因为很少有研究应用这些分析方法来研究儿童或青少年的反馈处理，我们使用了一种细粒度的方法，在theta（4-8 Hz）频带的反馈（无胜利与胜利事件）中探索了16 ms增量的半赫兹。复小波频率分解显示，无增益反馈与增强的θ功率和相位相干性相关。我们观察到ERSP和ITC的条件和年龄差异，ITC的影响更大。从童年到青春期早期（13-14岁）的过渡与儿童或年龄较大的青少年相比，ITC对无赢反馈与赢反馈的差异增加，ITC对无赢反馈的差异增加（二次效应）。
We examined event-related electroencephalography (EEG) oscillations, including event-related spectral perturbations (ERSP) and intertrial coherence (ITC), to compare feedback processing during a chance-based reward vs. non-reward task in groups of 10-12-year-old (n = 42), 13-14-year-old (n = 34) and 15-17-year-olds (n = 32). Because few, if any studies have applied these analytic methods to examine feedback processing in children or adolescents, we used a fine-grained approach that explored one half hertz by 16 ms increments during feedback (no win vs. win events) in the theta (4-8 Hz) frequency band. Complex wavelet frequency decomposition revealed that no win feedback was associated with enhanced theta power and phase coherence. We observed condition and age-based differences for both ERSP and ITC, with stronger effects for ITC. The transition from childhood to early adolescence (13-14 yrs.) was a point of increased differentiation of ITC favoring no win vs. wins feedback and also compared to children or older adolescents, a point of heightened ITC for no win feedback (quadratic effect).
