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.
