“…Brain event-related potential (ERP) studies have identified the ERN as a robust marker of anterior cingulate cortex-mediated cognitive control processes invoked by performance errors (Holroyd & Coles, 2002;Yeung, Botvinick, & Cohen, 2004). The ERN is clearly evident in adolescents as well as adults (Davies, Segalowitz, & Gavin, 2004) and, more recently, has been observed in young children (i.e., ages 5-11; Kim, Iwaki, Imashioya, Uno, & Fujita, 2007;Torpey, Hajcak, Kim, Kujawa, & Klein, 2012;Wiersema, van der Meere, & Roeyers, 2007). The ERN thus represents a neurophysiological marker of cognitive control across development.…”
