To date, the results of ERP studies on age-related feedback effects suggest that FRNs are generally greater in magnitude in younger groups (10-12 vs. 19-24 years, Eppinger, Mock, and Kray, 2009; 9-11 vs. 13-14, 30-40, 65-75 years, Hämmerer, Li, Müller, & Lindenberger, 2011; 10-12, 13-14 vs. 15-17 years, Crowley et al., in press; 14-17 vs. 22-26 years, Zottoli and Grose-Fifer, 2011). Some studies suggest greater differentiation of ERP responses for positive vs. negative outcomes across development (Hämmerer, Li, Müller, & Lindenberger, 2011; Zottoli and Grose-Fifer, 2011. There is also some evidence that FRN latency decreases from childhood through adolescence (Crowley et al., in press; Zottoli and Grose-Fifer, 2011). However, ERP studies have not documented any adolescent-specific reward processing changes at the level of the FRN.
