Abstract

despite general agreement that altered reward sensitivity is involved in attention-deficit/hyperactivity disorder (adhd), a wide range of different alterations has been proposed. we cite work showing abnormal sensitivity to delay of reward, together with abnormal sensitivity to individual instances of reward. we argue that at the cellular level these behavioural characteristics might indicate that dopamine timing is off in children with adhd.
