Choices between positive and negative reinforcement during treatment for escape-maintained behavior.

DeLeon et al. (2001) let kids with autism choose between two ways to earn a break. One way was positive reinforcement: finish a task, then play for a minute. The other way was negative reinforcement: the adult kept giving demands until the child did one, then the adult backed off.

The team also used escape extinction. That means the kids could not leave the table until they finished the work. The therapists slowly made the work longer to see what would happen.

At first, positive reinforcement won. Kids worked faster and had fewer problem behaviors when the reward was a fun break.

When the work chunk grew to ten tasks in a row, the good effects fell apart. Kids started to protest again and their break choice flipped from day to day.

Ward et al. (2017) later showed you can skip escape extinction entirely. They gave a quick ‘wait out’—the child simply lost the chance to work for 30 s. Problem behavior dropped and learning sped up. This updates the 2001 lesson: you may not need to sit through the storm.

Griffith et al. (2012) proved that timeout works because it stops effort, not because it removes something bad. Their lab data back up why the kids in DeLeon et al. (2001) liked the break: stopping work is the real prize.

Critchfield et al. (2003) issued a warning. If the child likes the task more than the prize, your ‘reinforcer’ can turn into a punisher. That may explain why, at ten tasks, the once-fun break lost its power in the 2001 study.

Start with positive reinforcement for escape behavior, but do not push the schedule too thin too fast. When work blocks grow and compliance slips, switch to brief wait-outs instead of toughing it out. Always check that your reward still beats the task itself—if the child would rather keep working, your ‘reinforcer’ may be working against you.
