DEVELOPMENT OF ERROR MONITORING ERPs IN ADOLESCENTS

In a target discrimination task, trials with incorrect responses elicit event-related potentials (ERPs) that include two components, an error -related negativity (ERN) and a later error-positivity (Pe). Substantial evidence points to the anterior cingulate cortex (ACC) as the source generator of the ERN1,2 and it is modeled to be dopaminergically driven.3 The ACC is involved in executive functions with major connections between the prefrontal cortex (PFC) and limbic system. 4 Given the continued maturation of the ACC, PFC, and domamine systems into young adulthood, our aim was to investigate the development of ERPs to correct and incorrect (error) responses.
