A token system for a class of underachieving hyperactive children.

The researchers worked with 18 hyperactive third-grade boys who were behind in reading.

They set up a cooperative token system. Kids earned points for finishing reading and vocabulary tasks.

Points bought game time at recess. The class had to meet a group goal before anyone could cash in.

When tokens were on, the boys finished more than nine times the work.

Reading test scores doubled.

When tokens stopped, work dropped. When tokens came back, work soared again.

Burgess et al. (1971) and Phillips (1968) used tokens earlier with pre-delinquent boys in group homes. They focused on chores and punctuality, not schoolwork. W et al. moved the same idea into a classroom and aimed it at academics.

Cihon et al. (2019) later tested a flexible token rule for kids with autism. They kept the exchange number secret so kids would keep talking. The 1981 study used a fixed, class-wide goal instead. Both worked, but for different skills and ages.

Hangen et al. (2023) warns that tokens alone can be weak. They found primary reinforcers beat tokens in a lab. W et al. avoided this pitfall by tying tokens to highly loved recess games, not just praise.

You can run this system tomorrow. Pick one subject, set a clear class goal, and let tokens buy a favorite activity. Track work output each day. If you see the same jump, keep going and fade points slowly.
