本研究考察了8-14岁儿童在执行Go/No-Go任务时反馈相关负性（FRN）大小的年龄相关变化。研究人员向参与者提供了四种刺激，并要求他们通过反馈引导的试错法将每种刺激映射到一种反应或“无反应”。反馈对于两个刺激（Go和No-Go）是有效的，并且对于另外两个刺激是无效的（0.5正反馈; 0.5负反馈）。对于Go和No-Go试验，分别评价了FRN振幅随年龄的变化。结果表明，虽然有效的围棋试验的性能随着年龄的增长而提高，但有效的No-Go试验的准确性随着年龄的增长而保持稳定。FRN振幅被发现是负相关的年龄，较小的FRN振幅观察到年龄较大的儿童，即使在控制学习的方差。此外，FRN被发现是Go试验中学习后表现的预测因子，但不是No-Go试验，无论年龄如何。这些结果并不支持FRN和抑制控制之间的联系，如No-Go性能所测量的，但确实表明与Go条件所要求的其他执行控制能力之间的联系。
The study examined age related changes in the magnitude of the Feedback Related Negativity (FRN) in 8-14 year old children performing a variation of a Go/No-Go task. Participants were presented with four stimuli and tasked with mapping each of them either to a response or to a "no response" by trial and error guided by feedback. Feedback was valid for two stimuli (Go and No-Go) and invalid (.5 positive; .5 negative feedback) for the other two stimuli. The amplitude of the FRN was evaluated as a function of age separately for Go and No-Go trials. The results indicated that while performance on valid Go trials improved with age, accuracy on valid No-Go trials remained stable with age. FRN amplitude was found to be inversely related to age such that smaller FRN amplitudes were observed in older children even after controlling for variance in learning. Additionally, the FRN was found as a predictor of post-learning performance on Go trials but not on No-Go trials, regardless of age. These results do not provide support to the link between the FRN and inhibition control as measured by No-Go performance, but do suggest a link with other executive control abilities called for by the Go condition.
