The development of performance-monitoring function in the posterior medial frontal cortex

Interference- and error-processing were associated with robust activation of the pMFC in both youth and adults. Among youth, interference- and error-related activation of the pMFC increased with age, independent of performance. Greater accuracy associated with greater pMFC activity during error commission in both groups. Discussion: Increasing pMFC response to interference and errors occurs with age, likely contributing to the improvement of performance monitoring capacity during development.
