The initial sample consisted of 113 children (57 females and 56 males), recruited via a mass mailing list provided by a credit mailing company, Experian, targeting the towns surrounding New Haven, CT. Children were fluent in English and had no evidence of serious mental illness (psychosis, autism, bipolar disorder) assessed via a parental telephone screen. Children carrying a diagnosis of ADHD, per parent report, were also excluded (n = 3). Children were intellectually in the normal range (verbal IQ mean = 112.30, SD = 12.47, range 82–139). The mean age of the children was 13.54 yrs. (SD = 1.88 yrs., range = 10.10–17.77 yrs.). Among the total sample (n = 110), 91 children provided sufficient artifact-free ERP data for this report. Handedness was evaluated using the Edinburgh Handedness Inventory (Oldfield, 1971) yielding a mean handedness quotient of .54 (SD = .50, range, −1.00 −1.00) on a scale where more positive scores indicate greater degrees of right-handedness. Ten of the children in the sample were left-handed (scores below −.40) and seven of these provided sufficient ERP data. Among the final sample
