differential-reinforcement

Differential reinforcement in ABA selectively reinforces desired behaviors while withholding reinforcement for undesired ones. It targets behavior function by applying procedures like DRA and DRO to increase functional responses and reduce problem behaviors across clinical and classroom settings.

To create a DRA plan, identify the function of the problem behavior, select a functionally equivalent alternative behavior to reinforce, specify reinforcement schedules, and implement extinction by withholding reinforcement for the undesired response. Schedule thinning and procedural fidelity strategies guide maintenance.

DRI reinforces incompatible behaviors, DRO reinforces absence of the target behavior, DRL reinforces behavior below a rate criterion, and DRH reinforces behavior above a rate criterion. Each differential reinforcement variant targets behavior reduction or frequency modification based on specific clinical goals.

Differential reinforcement procedures apply across both classroom and clinical ABA contexts. Educators can implement DRA and DRI plans with concrete criteria to shape student behavior, using specified reinforcement schedules and fading strategies to maintain desired responses.

Schedule thinning gradually reduces reinforcement frequency after desired behaviors are established. It requires specifying initial reinforcement schedules and applying fading strategies with procedural fidelity checks to maintain behavior reduction and ensure extinction procedures remain effective during maintenance.

Identifying behavior function is necessary because differential reinforcement requires selecting an appropriate DR procedure matched to that function. Without functional analysis, reinforcing an alternative behavior cannot effectively compete with the maintaining reinforcement driving the problem behavior.
