Negative reinforcer magnitude manipulations for treating escape‐maintained problem behavior

Rogalski et al. (2020) asked how big the break gap must be to stop escape behavior. They worked with three children who had developmental delay. The team used an alternating-treatments design. Kids got a tiny 10-second break if they hit or screamed. They got 240 seconds—four full minutes—if they followed the task.

The study tested smaller gaps too, but only the 24-to-1 ratio stayed strong across every child.

The huge break gap wiped out problem behavior for all three kids. Smaller gaps helped a little, but gains faded. Clinically big change showed up only with the 240-second versus 10-second split.

In short, a whopper difference in escape time is needed for durable effects.

Duker et al. (1996) got zero destruction by mixing DRA, escape extinction, and demand fading. Rogalski keeps escape extinction out and still wins by cranking up the break size. The two studies line up: both reward compliance with longer escape, but the new paper shows magnitude alone can do the job.

Cividini-Motta et al. (2024) reviewed skill-building with differential reinforcement. They say tweak the schedule, not the size. Rogalski flips that idea for problem behavior—here, size is the lever. Different goals, different knobs.

Waller et al. (2010) handed out breaks every few minutes no matter what. That non-contingent plan also cut disruption, but kids got relief whether they worked or not. Rogalski’s plan ties the big break only to compliance, giving teachers a clearer rule.

If you run an escape-based DRA program, check your break ratio. A skinny gap may not be enough. Start with at least a 20-to-1 split: give twenty-plus seconds of break for compliance, one or two for problem behavior. Watch the data; if behavior creeps back, widen the gap before adding more procedures. You might save time and keep extinction in place without extra components.
