Differential reinforcement is an ABA technique that increases a chosen behavior by reinforcing it consistently while withholding or reducing reinforcement for other responses. It works by making the desired behavior the most rewarding option available to a child or client. Practitioners typically choose among four main variations, DRA, DRI, DRO, and DRL, depending on whether the goal is teaching a new skill, replacing a behavior, or simply reducing how often something happens.

TL;DR:

• Differential reinforcement techniques must be matched precisely to the behavior’s function, with DRA and DRI preferred for teaching skills and DRO for reducing problem behaviors.
• Combining reinforcement parameters such as quality, immediacy, magnitude, and schedule optimizes behavior change, with stacking these approaches accelerating progress.
• Functional communication training, a form of DRA, is effective when the replacement response is function-matched and schedule thinning is carefully implemented.
• Effectiveness varies across types and populations, with DRA and DRI showing consistent success, though long-term maintenance and generalization remain less studied.
• Implementing a differential reinforcement plan requires clear behavior definitions, careful reinforcer testing, ongoing data collection, and caution to ensure safety and ethical practices.

Choosing the right type: DRA, DRI, DRO, and DRL explained

Each type of differential reinforcement solves a slightly different clinical problem, and matching the type to the goal matters as much as the reinforcement itself.

• DRA (differential reinforcement of alternative behavior): reinforces a specific replacement response, such as praising a child for raising a hand instead of shouting out in class.
• DRI (differential reinforcement of incompatible behavior): reinforces a behavior that physically cannot happen at the same time as the problem behavior, like rewarding a child for keeping hands in pockets instead of hitting.
• DRO (differential reinforcement of other behavior): reinforces the absence of the target behavior for a set interval, such as giving a token if no tantrum occurs during a 10 minute stretch.
• DRL (differential reinforcement of low rates): reinforces a reduction in how often a behavior occurs, useful for behaviors that are not dangerous but happen too frequently, like excessive questions during a lesson.
• DRH (differential reinforcement of high rates) works the opposite way, rewarding an increase in frequency when a behavior is desirable but underused.

DRA and DRI tend to fit best when the goal includes building a skill or independence, while DRO suits situations where any reduction in problem behavior counts as progress, according to a systematic review of differential reinforcement definitions. DRL and DRH are less common but valuable when frequency, not presence or absence, is the concern.

How reinforcer quality, timing, and schedule shape results

The type of differential reinforcement matters less than the specifics of how it’s delivered. Four parameters, quality, magnitude, immediacy, and schedule, determine whether a procedure produces fast, durable change or barely moves the needle.

• Quality: a favorite snack or toy reinforces more strongly than a generic sticker.
• Magnitude: a longer play break outweighs a 10 second acknowledgment.
• Immediacy: reinforcement delivered right after the response builds a stronger association than a delayed reward.
• Schedule: reinforcing every instance early on, then thinning over time, sustains behavior without creating dependence on constant rewards.

A review of experiments manipulating duration, quality, and delay found that combining these dimensions, rather than adjusting just one, produced the largest and most consistent behavior changes, even in cases where the problem behavior still occasionally received some reinforcement. In practice, that might mean pairing an immediate high-quality edible with enthusiastic praise for an independent correct response, while a prompted response earns only a small acknowledgment.

Pro Tip: Stacking two or three parameters, like quality plus immediacy, tends to work faster than relying on a single reinforcement change alone.

Functional communication training as a real-world DRA application

Functional communication training, or FCT, is one of the most widely used forms of DRA. Instead of teaching a general replacement behavior, FCT teaches a child a specific communicative response, like a phrase, sign, or card, that serves the same function as the problem behavior it replaces.

1. Assess the function: a functional behavior assessment identifies whether the behavior seeks attention, escape, a tangible item, or sensory input.
2. Teach the communicative response: the child learns a simple, function-matched way to ask for what they want, such as “break, please” for escape-motivated behavior.
3. Thin the reinforcement schedule: reinforcement shifts from constant to intermittent, often using visual cues that signal when a request will be honored.

A review and synthesis on functional communication training describes FCT as a widely published, effective DRA-based treatment when the replacement response is function-matched and paired with careful schedule thinning. When full extinction of the problem behavior isn’t safe or feasible, therapists often lean on quality and immediacy manipulations instead, making the alternative response noticeably more rewarding than the old one.

What the research says about effectiveness and its limits

Differential reinforcement carries decades of empirical support, though the strength of that evidence varies by type and population.

• DRA and DRI show consistent effectiveness across a wide range of behaviors and populations, though a broad review of DRA literature notes that many studies skip a formal functional analysis, which limits how confidently results generalize.
• DRO has documented success reducing challenging behavior in children with autism, but a systematic quality review of DRO studies found study quality varies considerably and outcomes depend heavily on implementation detail.
• Verbal rules paired with DRO, such as stating that a reward will be lost if the behavior occurs, can strengthen its effect in some controlled comparisons.

A systematic review of differential reinforcement in skill acquisition found that favoring independent responses with higher-quality reinforcement typically sped up mastery compared to treating all correct responses the same. Matching the alternative behavior to the function of the original behavior remains one of the strongest predictors of success across the literature. Long-term maintenance and generalization across settings remain the least studied pieces of the puzzle, and replication for some DRL and DRH applications is still thin.

Setting up a differential reinforcement plan step by step

A well-built DR procedure follows a sequence rather than a guess. Skipping steps is where most plans lose effectiveness.

1. Define the target behavior and assess its function. Write an observable definition and identify what the behavior achieves for the child using a functional assessment.
2. Choose the DR type that matches the goal. Pick DRA or DRI when teaching a replacement skill matters, DRO when any reduction counts as progress, and DRL when frequency is the real concern.
3. Test reinforcers before relying on them. A brief preference assessment identifies what’s genuinely motivating, then plan the schedule, prompts, and caregiver training around it.
4. Implement with data from day one. Collect baseline measurements, track ongoing progress, watch for collateral behaviors that might emerge, and build a plan for generalizing gains beyond the therapy room.

Reviewing sequences of antecedents and behaviors, sometimes called a behavior chain analysis, can help identify exactly where reinforcement timing needs adjusting when progress stalls.

Keeping differential reinforcement safe, ethical, and effective

Differential reinforcement should always be the least restrictive option that matches the behavior’s function, with informed consent from caregivers before implementation begins.

• Reinforcing problem behavior by accident, such as giving attention during a meltdown, undermines the entire procedure.
• Relying on full extinction when it isn’t safe, such as with self-injury, can escalate risk rather than reduce it.
• Poor generalization planning means gains made in one room rarely transfer to school or home without deliberate effort.

Mitigating these risks starts with a proper functional analysis, a documented safety plan, gradual schedule fading, and involving a BCBA whenever behaviors carry any safety risk.

What experienced clinicians want families to know

Differential reinforcement isn’t a punishment substitute, it’s a teaching tool, and confusing the two leads to frustration on both sides. Families should expect gradual acquisition, not overnight change, and should treat any sudden spike in problem behavior (an extinction burst) as a signal to consult a BCBA rather than abandon the plan.

Red flags that warrant specialized involvement include self-injury, aggression that escalates despite consistent implementation, or a total lack of progress after several weeks. Caregiver training remains one of the strongest predictors of lasting change, because behavior learned in a clinic only sticks when it’s practiced and reinforced at home too.

Getting support with differential reinforcement at home

Reading about DRA, DRO, and reinforcement schedules only goes so far when a child is mid-tantrum and the plan feels harder to execute than it looked on paper. Individualized treatment plans can be built around each child’s specific behaviors and functions, then paired with parent coaching so families aren’t left guessing how to apply these procedures consistently at home. Teams with extensive experience match reinforcement strategies to what actually works for a given child, not a generic template.

If your family is working through behavior goals that call for a function-matched plan, our ABA autism therapy services start with an assessment to identify the right approach for your child, and our parent coaching program helps you carry that plan into daily routines with confidence. Reach out today to schedule an assessment and get a plan built around your child’s needs.

FAQ

What is a differential reinforcement example?

A common example is praising a child for using words to ask for a toy while withholding attention when the child grabs it without asking. This teaches the child that the communicative response, not the grabbing, gets the desired result.

What are DRO, DRI, DRA, and DRL all examples of?

DRO, DRI, DRA, and DRL are all forms of differential reinforcement, a category of ABA procedures that reinforce specific response patterns to increase desired behavior or decrease unwanted behavior, according to a systematic review of differential reinforcement definitions. Each targets a slightly different goal, from teaching a replacement skill to simply reducing how often a behavior occurs.

What are the four types of reinforcement?

The four main forms of differential reinforcement are DRA (alternative behavior), DRI (incompatible behavior), DRO (other behavior), and DRL (low rates), with DRH (high rates) sometimes included as a fifth variation. Each is chosen based on whether the goal is teaching, replacing, or adjusting the frequency of a behavior.

What is an example of a DRI?

A DRI example is rewarding a child for holding a stress ball during a lesson instead of picking at their skin, since the two actions cannot physically happen at once. Because the reinforced behavior is incompatible with the problem behavior, it naturally crowds out the unwanted response over time.
