As used in Applied Behavior Analysis (ABA) therapy, differential reinforcement is a behavior modification technique.
What is ABA therapy? ABA is an evidence-based approach that’s centered on understanding and subsequently improving specific behaviors through reinforcement and other methods.
If you’re wondering what is differential reinforcement in ABA, it’s a therapeutic method built on the core principles of reinforcement (increasing the likelihood of a behavior), extinction (reducing behaviors by eliminating rewards), and discrimination (teaching individuals to differentiate between which behaviors are acceptable in a given situation).
In contrast to using punishment, differential reinforcement helps individuals with autism engage in more socially acceptable or functional behaviors by rewarding positive actions. It often involves shaping behavior, another ABA technique that reinforces small steps toward a larger, desired behavior.
For example, if a child on the spectrum throws a tantrum every time they need help, a therapist might reinforce the behavior of asking for assistance instead. While the child may only exhibit the behavior half the time, the therapist persists until the child can reliably use it. Over time, the undesired behavior decreases, and thanks to meaningful outcomes, the desired behavior grows.
Why is differential reinforcement important in ABA?
By reinforcing only the appropriate behavior and withholding reinforcement for less desirable ones, autistic individuals learn which actions lead to meaningful results. All of this is done without the use of punishment. For those asking what is differential reinforcement in ABA, it’s a flexible, evidence-based technique that teaches positive behaviors in real-life settings.
Whether the goal is to improve focus at home, build communication skills, or reduce disruptive behaviors in the classroom, differential reinforcement offers a highly flexible approach to supporting long-term behavioral growth across various environments.
Types of differential reinforcement
Each type of differential reinforcement has been created to serve a specific purpose, depending on the behavior you’re trying to reduce and the outcome you want to encourage. The multiple types of differential reinforcement allow ABA therapists, parents, teachers, and other caregivers the opportunity to customize interventions to the autistic individual’s needs and the specific situation.
Differential reinforcement of alternative behavior (DRA)
DRA entails reinforcing a socially acceptable behavior while discouraging the problem behavior. For example, if a child throws things to get a parent’s attention, through ABA parent training, the adult might learn to ignore the yelling but respond immediately when the child says, “Excuse me, Mom.” This teaches the child that using socially acceptable language is the most effective way to get their mother’s attention.
Differential reinforcement of incompatible behavior (DRI)
In DRI, reinforcement is given for a behavior that prevents the unwanted type from co-occurring. A good example of this is if an autistic child is prone to hitting others or exhibiting other types of aggressive behavior. A therapist might instead reinforce holding a fidget toy or clapping hands, neither of which can happen if a child is striking people around them.
Differential reinforcement of other behavior (DRO)
DRO is an approach that involves reinforcing the absence of a particular unwanted behavior within a designated period. Rather than focusing on a replacement behavior, not engaging in the less desirable behavior rewards the autistic individual. For example, a teacher might use positive reinforcement ABA, such as verbal praise or a reward (e.g., a sticker), every 15 minutes when the autistic student doesn’t interrupt their lesson. This action encourages the student to maintain control and stay on task while gradually reducing disruptive behavior.
Other types of differential reinforcement
Differential reinforcement of low rates of behavior (DRL) is often employed to reduce the frequency of a behavior without eliminating it. For example, praising a student for limiting how frequently they raise their hand or talk with other friends during class is an example.
Differential reinforcement of high rates of behavior (DRH) is often used to increase the frequency of socially acceptable behavior. For example, rewarding a student for completing more of their English homework in class than they usually do.
For caregivers and parents
It’s essential to remember that differential reinforcement strategies can be used in a range of settings, including the community, at home, and in school. They’re a tremendously effective tool for teaching positive behavior. To begin, choose a behavior that you want to change and then select a positive behavior you want to replace it with. This type of process takes consistency and excellent timing.
However, if your child’s behaviors are severe, persistent, or you’re noticing patterns that resemble the symptoms of high-functioning autism, and you’re unsure which strategies to use, consulting with an ABA professional is your best option. They have the experience and expertise to develop a plan tailored to your child’s needs.
How differential reinforcement works in ABA: step-by-step
To understand what differential reinforcement is in ABA, it helps to examine its applications. Differential reinforcement utilizes both positive and negative reinforcement to increase desired behavior, making it a key component of shaping behavior in both clinical and ABA therapy at home.
Identify the target and replacement behaviors.
Take a moment to identify the behavior you want to reduce and the socially acceptable behavior you want to foster (e.g., replacing hitting people with asking for what they need)
Choose the appropriate reinforcement strategy (DRA, DRI, DRO)
Select the proper method of ABA positive reinforcement, whether it’s DRA, DRI, or DRO, based on the situation.
Consistently apply reinforcement and withhold it for undesired behaviors
Reinforce the desired behavior each time it occurs and withhold reinforcement for the unwanted behavior. With consistency, the autistic individual will learn which actions lead to positive outcomes.
Monitor and adjust based on progress.
Track the reinforcement progress and make necessary adjustments when needed, particularly when reshaping a child’s behavior.
Challenges and limitations of differential reinforcement
Despite the fact that differential reinforcement is an effective and widely used therapeutic tool in behavior modification, it is not without its challenges. Thoughtful planning, continuous adjustments, and a high level of consistency are all required by caregivers, therapists, and educators to ensure the successful implementation.
Choosing the correct type of reinforcement
One of the most crucial and often challenging aspects of utilizing differential reinforcement is selecting the appropriate type. Whether it’s DRI, DRO, or DRA, each has a specific application, and using the wrong one can fail to reduce the target behavior. Selecting the correct reinforcement means it must be significant and motivating for the autistic individual. The same can be said for the replacement behavior, which must serve the function of the problematic one.
Ensuring consistency, patience, and the need to adjust strategies
It’s important to remember that differential reinforcement is not designed to be a quick fix. Just the opposite, it requires patience, time, and ongoing practice before results can be seen. Whether parents, educators, therapists, or other caregivers, everyone involved in the therapeutic process must consistently apply the reinforcement strategy. Intermittent use can slow progress or even reinforce less desirable behaviors. Additionally, the reinforcement strategies will also need to be continuously adapted as the individual’s needs evolve.
Note potential challenges: requires consistency, careful planning to avoid reinforcing other problem behaviors.
The risk of unintentionally encouraging other problem behaviors can pose a challenge when implementing differential reinforcement. This can happen if it is delivered without careful observation or at the wrong time. In these situations, it may strengthen less desirable behaviors. Interventions should be carefully executed and regularly monitored, with clear criteria outlining how and when reinforcement should be delivered to avoid this scenario.
The role of ABA therapy in differential reinforcement
When guided by the principles of ABA therapy, differential reinforcement is the most effective approach. ABA professionals, including BCBAs (Board Certified Behavior Analysts) and RBTs (Registered Behavior Analysts), are uniquely trained to identify triggers, select the appropriate strategy (DRO, DRA, or DRI), and ensure its consistent use.
Trained and certified ABA therapists can develop individualized behavior plans tailored to an autistic individual’s specific needs, communication style, and environment. For the best outcome, consult with a local ABA professional. Together, you can create a plan that’s clear, consistent, and designed to deliver measurable results.

Frequently Asked Questions about Differential Reinforcement
Is punishment used in differential reinforcement?
No. Differential reinforcement does not use punishment. Rather, it focuses on encouraging positive behaviors while withholding reinforcement for less desirable ones.
Is differential reinforcement only for children with autism?
No, it can be used for individuals of all abilities and ages. Yes, it may be used more commonly in autism interventions, but it’s applicable and effective for a wide variety of behavioral challenges.
How do you choose which type of differential reinforcement to use?
The choice depends on several factors, including the behavior you want to reduce and the behavior you want to encourage. A certified ABA professional can help match the right type to your specific needs.
How do you know if differential reinforcement in ABA is working?
A sure sign it’s working is seeing a decrease in the unwanted behavior and a gradual increase in the desired behavior. This type of progress is typically tracked through keen observation and data collection.
