For both the ERP and source data, analyses employed repeated measures ANOVAs, and all F-tests are reported with the Greenhouse-Geisser correction (Greenhouse & Geisser, 1959). Repeated measures ANOVAs consisted of Condition (reward vs. non-reward) as the within subjects factor and Sex (Male vs. Female) and Age Group (10–12 yrs., 13–14 yrs., 15–17 yrs.) as between subjects factors. Analyses for source data included an additional within subjects factor, Region (BA 10, BA 11, BA 24, BA 25, BA 32).
