Differential effects of methylphenidate and self-reinforcement on attention-deficit hyperactivity disorder.
Kids with ADHD can double their work output by giving themselves small rewards, and the gain is even larger if meds stay on board.
01Research in Context
What this study did
Researchers worked with six boys who had ADHD. All were in a regular fourth-grade classroom.
The team tested three setups in rapid rotation: kids took Ritalin, kids gave themselves points for reading, or kids did both. Each condition lasted one day and the order shuffled for three weeks.
What they found
Self-reinforcement alone doubled the number of reading questions the boys finished. Adding Ritalin pushed the total even higher.
Kids stayed in their seats longer and made fewer careless errors when they managed their own rewards.
How this fits with other research
Richman et al. (2001) later showed the same boost works for mixed-ability students. They compared student-delivered tokens with teacher-delivered tokens and still saw gains, proving the effect isn’t tied only to ADHD.
May (2019) used the same fast-switch design but gave teacher praise instead of self-points. Both studies raised on-task behavior, yet self-reinforcement let the child control the payoff, a step toward true self-management.
McKenna et al. (2019) reviewed studies on students with emotional disturbance in inclusive rooms and found almost no solid academic data. Ajibola et al. (1995) fills that gap by giving teachers an evidence-based option that can be used right away.
Why it matters
You can cut medication reliance and build life-long self-control at the same time. Teach the learner to set a tiny goal, track it, and hand himself a sticker or point when he meets it. Start with five-minute blocks during independent work. Pair the system with any current meds instead of viewing them as either-or. The skill stays when the pill wears off.

03Original abstract
Six boys aged 9 to 12 years attended a tutoring class focusing on reading for 30 minutes each morning. The investigators employed a modified Latin-square design in which each child began with a 5-day baseline phase followed by six 10-day treatment phases that used drug placebo, noncontingent reinforcers, 0.3 mg/kg methylphenidate, 0.7 mg/kg methylphenidate, and self-reinforcement in various combinations. Amount of academic performance was the major measure of outcome and the target behavior of self-reinforcement. Drug placebo and noncontingent reinforcers had no systematic impact. Methylphenidate had differential effects across the recorded behaviors. Self-reinforcement improved the target behavior; the mean effect size for self-reinforcement was 2.66. The combined effects of methylphenidate and self-reinforcement on academic performance were greater than either of the treatments given alone (mean effect size = 2.89).
