Rules and Statements of Reinforcer Loss in Differential Reinforcement of Other Behavior

The team added a short rule to a basic DRO plan.

Right after problem behavior, the adult said exactly what the child would now lose.

They tested the tweak with three clients who had severe problem behavior.

A single-case design showed how each child did with and without the rule.

Problem behavior dropped sharply for every participant once the rule was added.

Two clients also showed more good behavior that was never directly rewarded.

The simple statement of reinforcer loss made the DRO work faster and better.

Hronek et al. (2025) seems to disagree. Their lab study found that small DRO errors can erase all gains or even make behavior worse. The key difference is population and control: Hronek used neurotypical adults and purposely broke fidelity, while Iannaccone kept high fidelity and added a verbal rule.

Zhou et al. (2018) used a cousin plan, full-session DRL, and also cut severe problem behavior. Both papers show that careful DR schedules work, but Iannaccone’s rule statement may give you the same punch in less time.

Craig et al. (2018) paired DRO with a clear context signal and saw less relapse later. Adding Iannaccone’s verbal rule at the moment of loss could stack with their context cue for even sturdier treatment.

You can boost an everyday DRO in one minute. After problem behavior, simply name the lost item or activity, then move on. No extra tokens, no new data sheets. Try it with your next DRO case and watch the curve drop faster.
