Treating stereotypy in adolescents diagnosed with autism by refining the tactic of "using stereotypy as reinforcement".

Potter et al. (2013) worked with three high-school students with autism. All had hand-flapping or finger-flicking that got in the way of schoolwork.

The team let the teens earn 5- to 30-second stereotypy breaks by finishing small chunks of leisure or academic tasks. They slowly asked for longer work before each break.

When the breaks were delivered right away, stereotypy dropped during work time and useful responding went up. The refined plan kept the gains even when staff faded the prompts and timers.

Osnes et al. (1986) first showed the idea with a 13-year-old boy who earned object-spinning time; Potter et al. (2013) updated the tactic for older teens and added a progressive schedule.

Wilson et al. (2020) took the opposite path. Instead of giving stereotypy, they reinforced singing and still cut vocal stereotypy. Both studies show differential reinforcement works, just with different reinforcers.

Li et al. (2025) later tested preschoolers using response-stimulus pairing. Their positive results stretch the stereotypy-reduction theme to a much younger group, showing the issue spans ages.

You can turn the very behavior you want to decrease into a powerful reinforcer. Start with tiny work requirements and slowly stretch the interval. The student gets control of the break timer, you get more on-task behavior, and stereotypy stays low even when you step back.
