In this section, 64 typically developing children (controls) were compared to 35 participants with ADHD-C. To control for the effects of motion, the groups were matched by mean FD, as explained above. Only combined-type ADHD (ADHD-C) participants were included in the direct comparison, because, given the theorized association between reward processing impairment and impulsive symptoms, the ADHD-C group is expected to present greater impairment in reward processing.
