Behavioral Momentum: What It Is and How to Use It Effectively in ABA
In the fast-paced world of applied behavior analysis (ABA), we’re often looking for tools that are effective, easy to implement, and rooted in solid behavioral science. Behavioral momentum is one of those tools—and when used correctly, it can make sessions smoother and more successful for both the client and the behavior technician.
Whether you’re an RBT just starting out or a BCBA mentoring a supervisee, this post breaks down what behavioral momentum is, why it works, and how to use it. Plus, I’ve created a free downloadable visual you can use to train RBTs or hang in your therapy room.
What Is Behavioral Momentum?
Behavioral momentum is a strategy that uses the momentum of high-probability (easy) tasks to increase the likelihood that a client will complete a low-probability (more difficult or non-preferred) task.
Think of it like rolling a ball downhill—once you’ve got it moving, it’s easier to keep it going. We build momentum with easy, fast, and reinforced responses, and then slide in a more challenging instruction while the client is “on a roll.”
The Formula:
- Identify 2–3 high-probability demands (things the learner is almost always compliant with)
- Deliver them quickly, with reinforcement or praise after each success
- Immediately follow with a low-probability demand (a task that is often refused, avoided, or completed with low motivation)
- Reinforce the low-p behavior when completed
Why Does It Work?
Behavioral momentum is grounded in the same principles as Newtonian momentum—objects in motion tend to stay in motion. When applied behaviorally, we capitalize on:
- Increased responding from successful, quick interactions
- Positive reinforcement stacking
- Reduced avoidance since the transition to the harder task is smoother and less abrupt
This technique is especially useful:
- During transitions
- When re-engaging after problem behavior
- With demand-sensitive learners or those with a history of escape-maintained behavior
Example in Practice
Let’s say you’re working with a learner who often resists writing their name.
High-P sequence:
- “Touch your nose.”
- “Clap your hands.”
- “Give me a high five!”
Then immediately:
- “Write your name.”
Now, the learner is primed with three quick successes, reinforcement is flowing, and you’ve increased the odds that they’ll follow through with the harder demand.
Tips for RBTs
- Keep the pace fast
- Use enthusiastic tone and strong praise
- Don’t pause too long between high-p and low-p tasks
- Reinforce that low-p response like it’s gold!
For BCBAs: Training Your Team
Behavioral momentum is a great strategy to teach in supervision or team meetings. I recommend modeling it in session, followed by roleplay and feedback. Provide examples that are specific to the learner’s current skill level and preferences.
To help you do just that, I’ve created a FREE printable visual guide you can use with your team!

Final Thoughts
Behavioral momentum isn’t just a fancy term—it’s a simple, powerful way to build cooperation and reduce problem behavior through positive interactions. When RBTs understand how and why it works, they’re more likely to use it consistently and effectively.
Use this post (and the visual!) to support your team in implementing this strategy with confidence.
