What is the Difference Between Contingent & Noncontingent Reinforcement in ABA?

difference between contingent and noncontingent reinforcement

In our ABA practices, we know the importance of shaping behaviors. One of the key tools we use is reinforcement.

The goal of all extrinsic reinforcement should always be to fade it eventually (move towards praise and intrinsic motivation). However, there are many situations, especially with beginner learners and with newer skills, we need a little extra motivation to assist with learning.

Terms such as contingent and noncontingent reinforcement are used a lot in ABA, but did you ever stop to consider the difference between them? Today, we’ll dive into these two types of reinforcement, explore their differences, and talk about how to choose the best strategy for different situations.

What is Reinforcement in ABA?

Reinforcement, simply put, is a way to increase the likelihood of a behavior. In ABA, we use it to shape behaviors and encourage desired responses. It’s a powerful tool to encourage skill acquisition and cultivate positive habits.

Let’s consider a real-life example. Imagine you’re teaching a learner who has a knack for avoiding math worksheets. How can we motivate him to complete it every time? One way could be to offer a point or token each time he finishes a problem. This is what we call contingent reinforcement because the reward is contingent on the completion of the task.

But there is also something called noncontingent reinforcement, which occurs regardless of task completion. Now, this might raise a question – what’s the difference between contingent and noncontingent reinforcement, and when should we use each?

Let’s dive deeper into both concepts and explore how they can help your students and your ABA practice!

Our reinforcement checklist can help you identify the most preferred reinforcers for your learners. Get it below!

What is Noncontingent Reinforcement?

Noncontingent reinforcement, or NCR, is life’s simple pleasures that just happen, regardless of what you do or don’t do. It’s the unearned good things we get to do – the spontaneous joys that just happen without us having to lift a finger.

Take a student’s art class, for example. No matter how their day is going, they still get to dip their brushes into colorful palettes and create their masterpiece. It’s their sanctuary of creativity and self-expression.

And what about recess? That’s another noncontingent given! Kids shouldn’t have to work to earn their playtime – it’s their right to have fun and get some wiggles out!

Noncontingent reinforcement is unique because it’s often scheduled and always unchanging or unaffected by behavior. It’s like a refreshing pause button that helps reset someone’s mood. Think of NCR as the magnet that draws students into the learning environment, opening doors for more structured activities.

Examples of Noncontingent Reinforcement

Let’s take a moment to think about our own lives. You can probably think of your own version of NCR. It might look like sinking into your couch at the end of the day and losing yourself in your favorite TV show – no strings attached!

Meanwhile, your learners might need regular movement breaks. If a student’s plan includes a sensory break every 20 minutes, those breaks are non-negotiable, regardless of whether their assignments are done or not.

Or consider an upcoming family trip. You wouldn’t cancel it just because your kid had a rough day, right? These NCR breaks might actually help reset behavior and lift spirits.

How to Integrate Noncontingent Reinforcement in Your ABA Practice

Here’s a little secret: we all need fun things in our lives. That’s the essence of NCR. It’s the fun factor that brings everyone to the table. It could be recess or lunchtime for kids, or that first cup of morning coffee for adults.

You can cleverly integrate these tools into the classroom routine. Perhaps ask kids to lend a hand in a task or set a timer for noncontingent activity time. It’s all about making the learning environment more inviting and exciting!

And remember, movement or sensory breaks should always be noncontingent. They’re as essential as breathing and should never be taken away.

What is Contingent Reinforcement?

Contingent reinforcement, as the name suggests, is all about dependencies. It’s the classic, “If you do this, then you get that” scenario. This type of reinforcement involves a reward, but to earn it, a task must be completed to a certain standard.

Contingent reinforcement is where the real magic happens. It’s like a motivating engine that powers students to acquire the skills they need.

Let’s bring this concept to life with an example. Imagine a student who loves collecting special stickers. To add one to their collection, they have to complete all their math problems. Here, the sticker is the contingent reinforcement.

The heart of contingent reinforcement lies in clear expectations. It’s crucial to ensure these expectations remain consistent throughout the task. Students need to know precisely what they’re working towards and the steps they need to take to get there.

When choosing rewards, think of things that are “extra” – access to a favorite activity, tech time, small treats, and so on. But remember, never turn noncontingent items into contingent ones.

Examples of Contingent Reinforcement

Contingent reinforcers could range from simple stickers or stamps to fun activities, snacks, or even an extra special silly break. As adults, we often set our own contingencies, don’t we? We might treat ourselves to a preferred activity after wrapping up work or household chores.

It’s important to strike the right balance. You don’t want the tasks to be so challenging that they lead to frustration. It is important to meet the student where they are at (i.e., think baselining). When teaching math, we don’t start with calculus. We start with the basics and then build from there. With toilet training, we start with reinforcing for simply traveling to the bathroom. Eventually, we only provide reinforcement for eliminating on the toilet.

Now, let’s examine a teaching example that we see all too often. Let’s pretend an instructor has set up a contingency that the student has to earn 10 tokens to earn their favorite toy. If the instructor provides tokens after each correct response, this is contingent reinforcement.

However, what if the instructor gave the student tokens even when she was not responding, slouching in her chair, and engaging in off-task behavior? It can be argued that this is actually noncontingent reinforcement, as the student got the tokens anyway, regardless of behavior. In the latter situation, what is the student learning? That they can tune out and still earn the end prize. Be careful!

How to Integrate Contingent Reinforcement in Your ABA Practice

Contingent reinforcements can significantly enhance learning and task awareness. The trick is to identify what motivates your learners and then weave those rewards into their tasks as incentives for effort or achievements.

What rewards will they eagerly work for? A fantastic way to uncover this is through preference assessments.

Remember to keep the contingency closely tied to the task at hand. Be immediate, specific, and consistent. Prompt if necessary to ensure success (but don’t forget those transfer trials!) Continue to maintain this approach, prioritizing clarity for both yourself and your students.

Contingent reinforcement is essentially a trade-off – a little effort for a delightful reward. It’s a strategy that can truly revolutionize the learning journey!

Contingent vs. Noncontingent Reinforcement: What’s the difference?

While both contingent and noncontingent reinforcement can be effective tools in ABA, they have distinct differences. Contingent reinforcement is based on specific behaviors, while noncontingent reinforcement is delivered on a set schedule, regardless of behavior.

Imagine you’re working with a learner who struggles with disruptive behaviors during class time. Using contingent reinforcement, you might provide a reward when the student stays focused for a certain period. With noncontingent reinforcement, you’d provide regular breaks or rewards at set intervals, regardless of their behavior. (Also remember to teach replacement behavior when managing challenging behavior!)

Which Reinforcement Strategy Should You Choose?

Choosing between contingent and noncontingent reinforcement depends on several factors – including the individual’s needs, the behavior being targeted, and the context. It’s important to remember that each individual is unique, and what works for one may not work for another.

When implementing contingent reinforcement, consistency is key. Ensure the reinforcement immediately follows the behavior and is meaningful to the individual. And remember, it’s always essential to monitor and adjust your strategies based on the individual’s progress.

What’s more: keep in mind that certain reinforcement should never be contingent. Take recess, for instance. We firmly believe it should stay in the noncontingent zone – it’s a right, not a reward that needs to be earned.

Drawing the distinction between contingent and noncontingent in our minds can be a game-changer, helping our kids grasp the difference between what they need to work for versus what they’re entitled to, just because!

Stay Aware & Affirmative

It’s crucial to maintain a clear understanding of the tools and strategies we use, including contingent and noncontingent reinforcement. Of course, it’s easy to confuse the two, especially when we’re managing challenging behavior in the moment.

As therapists, teachers, and parents, our first impulse might be to withhold certain privileges, like recess or playtime. However, it’s important to remember that these are noncontingent reinforcers. Taking them away can disrupt the consistency of positive experiences they provide and may inadvertently reinforce negative behaviors.

It’s also vital to stay affirmative! Don’t threaten to remove reinforcement. State, “Only 5 more and you get ____” instead, “If you don’t do these 5 questions, you won’t get____.”

Also remember that each child is unique. Their motivations, interests, and responses can change daily, needing a flexible approach from us as ABA therapists. It may sometimes feel like a balancing act, trying to find the sweet spot between contingent and noncontingent reinforcement. But with time, patience, and an unwavering belief in the child’s potential, you’ll discover a harmonious blend that effectively motivates and encourages positive behavior.


Understanding the difference between contingent and noncontingent reinforcement can significantly impact our effectiveness as ABA professionals. We can better shape behaviors and support our learners’ progress by choosing the appropriate reinforcement strategy.

So, whether you’re rewarding a child for completing a task or providing regular breaks to a student, remember the power of reinforcement in your practice.

  2. This is not a good description of “noncontingent reinforcement.” The example of accessing art class without regard to prior behavior is not noncontingent reinforcement. Noncontingent reinforcement (sic) is the presentation of a stimulus which has been identified through a functional analysis to be the maintaining reinforcer for a problem behavior. That stimulus is then presented on a time-dependent schedule with the frequency of delivery ideally being determined by being shorter than the IRT of the undesired behavior. By presenting the reinforcing stimulus independent of behavior, the contingency between the undesired behavior and the reinforcing stimulus is broken. The reinforcing stimulus is presented on a set time and therefore reinforces other behaviors, though those behaviors are not specified. (Yes, like a DRO). The example of gaining access to art class independent of behavior through the day prior to the class is far different.

    There are many who object to the term “noncontingent reinforcement” because reinforcement by definition is a contingency. One could say the reinforcement is following other behaviors and is therefore contingent on those behaviors, but there is no measurment of an increase in those other behaviors, so that part of the definition of reinforcement is not met.

    1. Hi Mark! You’re technically right about the oxymoron nature of the term “non-contingent reinforcement”. And while you describe one application of NCR in the treatment of problem behavior, that is not the only use. We try to put things into simple, layman’s terms and it would be very common to use the term non-contingent reinforcement in reference to getting something good that you don’t have to earn. It also helps teachers and other professionals understand how to react and why it’s important not to turn these kinds of activities into “rewards” or “punishments”. But, yes, it would only be reinforcement if it changes future likelihood of behavior 🙂
