One study showed that adolescents (ages 13 – 14) have comparable ERN amplitudes to adults (ages 23 – 24; Wiersema et al., 2007). On the other hand, Ladouceur and colleagues (2004) found that the ERN amplitude was larger in late adolescents (ages 14 – 17) compared to early adolescents (ages 9 – 14). Overall, these findings suggest that changes in ERN amplitude reflect developmental changes in the brain, possibly reflecting the continued maturation of the medial prefrontal cortex, with increasing ERN amplitude through childhood and adolescence that plateaus in late adolescents or early adulthood (Davies et al., 2004a, 2004b)
