This study examines the development of action monitoring in adolescence by measuring the N200, the ERN (error-related negativity) and the PE (error positivity), which are event-related potentials (ERPs) that appear to be generated in the anterior cingulate cortex (ACC) and reflect action-monitoring processes. We predicted that amplitude would be significantly greater in late compared to early adolescence. Participants consisted of 11 adolescents that were divided into early (age 9-14) and late (age 14-17) adolescence groups. ERPs were recorded during an 840-trial arrow-flanker task and using 128-channel dense array EEG. Results indicated that there were no differences in P E amplitude but that N200 and ERN amplitudes were greater in the late adolescence group. According to the conflict monitoring hypothesis, this suggests that the ability to detect error-related conflict, which is involved in the modulation of cognitive control, appears to be fully developed later in adolescence and may be linked to the maturation of the ACC.
