This study examined the use of a progressive delay procedure with and without a concurrent activity to teach self-control to children with attention deficit hyperactivity disorder. Three participants were initially required to wait progressively longer periods of time for access to preferred edible reinforcers. After demonstrating this self-control, they were tasked by waiting for engagement in an activity identified as a preferred reinforcer. Results show that self-control training of these types could enable a person to delay gratification in a participant's typical environment. (Contains 1 figure.)
