Behavioral data during scan. (A) Accuracy and (B) response times in a 1-back task during the scan. Light gray: adolescents ages 12–16 years; Black: adults ages 18–40 years. Error bars show standard error of mean (SEM) for each age group. Asterisk indicates significantly higher accuracy in adolescents than adults (P < 0.05, t-test).
