What is Positive Reinforcement in ABA Therapy?
In Applied Behavior Analysis (ABA) therapy, positive reinforcement is a core principle used to encourage the repetition of helpful behaviors. Positive reinforcement involves adding something desirable immediately after a behavior occurs, which increases the likelihood that the behavior will happen again in the future.
The goal is to strengthen behaviors that help children succeed in communication, social interactions, academic tasks, and everyday routines. For example, if a child receives praise or a small reward after making a verbal request, they’re more likely to use that skill again.
Positive reinforcement is widely used in both clinical settings and everyday environments like homes and schools. According to the Centers for Disease Control and Prevention (CDC), reinforcement strategies are a foundational element of evidence-based autism interventions (CDC source).

Positive Reinforcement Examples in ABA Therapy
Example 1: Reinforcing Communication
A child is learning to request a favorite toy using a speech-generating device. Each time they press the correct button, the behavior technician immediately gives them the toy. This positive reinforcement helps the child understand that communication leads to a desired result.
Example 2: Encouraging Task Completion
During a learning session, a child completes a puzzle. The behavior technician offers enthusiastic praise and allows them to choose a preferred game. This reward system encourages the child to stay engaged and finish tasks.
Example 3: Supporting Social Skills
A child shares a toy with a peer without being prompted. The behavior technician immediately offers a high-five and access to a fun activity. This positive consequence increases the likelihood of future sharing behaviors.

FAQs About Positive Reinforcement in ABA Therapy
How is positive reinforcement different from bribery?
Positive reinforcement is planned, consistent, and used to teach meaningful skills. Bribery is reactive and usually occurs after a behavior has already happened. In ABA therapy, reinforcers are delivered immediately after the desired behavior, not before.
What are examples of reinforcers in ABA therapy?
Reinforcers can include social praise (“Great job!”), access to a favorite toy or activity, edible treats, tokens, or special privileges. The key is that the reinforcer must be meaningful to the individual.
Why is timing important in positive reinforcement?
Reinforcement is most effective when it happens immediately after the behavior. This helps the child connect the behavior with the positive outcome, strengthening the learning process.
Can positive reinforcement reduce interfering behavior?
Yes. By reinforcing alternative or replacement behaviors, behavior technicians can decrease the frequency of interfering behaviors. For example, teaching a child to ask for help instead of engaging in interrupting behavior.
Do reinforcers always have to be tangible?
No. Many children respond well to non-tangible reinforcers such as verbal praise, smiles, or physical gestures like high-fives. Over time, ABA programs often fade tangible reinforcers in favor of social rewards.
Key Takeaways About Positive Reinforcement in ABA Therapy
- Positive reinforcement strengthens behaviors by adding a desired outcome immediately after the behavior.
- It is a central strategy in ABA therapy used to build communication, social, and daily living skills.
- Reinforcers must be tailored to each individual and delivered consistently.
- Positive reinforcement supports long-term behavioral change and skill acquisition.
- Both tangible and social reinforcers can be effective, and programs often evolve to rely more on naturalistic rewards.
