Abstract
The error-related negativity (ERN) and the error positivity (Pe) are electrophysiological components of error processing that develop throughout adolescence and into adulthood. As young people in their early 20s make many important life decisions, the inability to monitor and adapt behavior appropriately may interfere with their personal goals, such as educational or professional achievements. The aim of this study was to investigate age-related differences in error processing across young adulthood. Using electroencephalography and the go/no-go task, we examined behavioral (error rates, reaction times, posterror slowing [PES]) and event-related potential (ERN, Pe) indexes of error processing. Ninety-five participants were divided into three age groups: Early 20s (ages 19-21), Mid 20s (ages 23-26), and Early 30s (ages 28-44). At the beginning of the 20s, young adults still make impetuous errors and do not show PES afterward, contrary to young adults in their early 30s. Larger ERN and smaller Pe amplitude in Early 30s suggest that adult-like error processing results in early enhancement of effortful stimulus control mechanism (ERN) and the reduction in later response evaluation process (Pe). Our findings suggest that the response strategies, both behavioral and neurocognitive, which would assure stable performance resembling adult levels, may still not be reached in the early 20s. Well-timed interventions could help reduce the impact of these tendencies by introducing strategies that provide more efficient performance.
