Differential Reinforcement – A Powerful Tool for Positive Change

Managing and shaping behavior, especially for individuals with special needs, is a complex but essential aspect of education and caregiving. In this blog post, we will delve into a valuable behavior management strategy: Differential Reinforcement. This technique, which involves rewarding desired behaviors while ignoring or redirecting undesired ones, can be a powerful tool for promoting positive change. Let’s explore how it works and how you can apply it effectively.

What is Differential Reinforcement?

Differential Reinforcement is a behavior management strategy rooted in the principles of Applied Behavior Analysis (ABA). It focuses on encouraging and reinforcing positive behaviors while minimizing or eliminating unwanted behaviors. The core idea is to “differentiate” your response to various behaviors to encourage the desired ones. 

All that means is encourage the behavior you want to see more of and respond in a manner that causes the unwanted behavior to decrease. Although it seems simple, there are five different ways to use this strategy.

Types of Differential Reinforcement

1. Differential Reinforcement of Other Behavior (DRO): In DRO, you reward the individual when they do not engage in the target undesirable behavior for a specified period. For example, if a student is prone to aggressive behavior, you might reward them when they manage to remain calm for a set duration. This is most successful when starting off in small increments of time.

2. Differential Reinforcement of Incompatible Behavior (DRI): DRI involves rewarding behaviors that are incompatible with the undesirable behavior. That means that the behavior you are reinforcing cannot be done at the same time as the unwanted behavior.  For example, if a student is constantly picking their skin during lessons, you can give them a fidget to hold on to and reinforce that behavior. Then when he is holding the fidget, he cannot pick his skin at the same time.

3. Differential Reinforcement of Alternative Behavior (DRA): In DRA, you encourage an alternative behavior to replace the unwanted one.  What is key about this one is that the alternative behavior must serve the same function as the unwanted behavior.This means recognizing and reinforcing a more appropriate behavior that gets the student exactly what they were trying to get through the unwanted behavior. For example, if a student often disrupts class and you have decided that the function is attention, you could give praise and attention to them when they raise their hand to ask questions.

4. Differential Reinforcement of Low Rates of Behavior (DRL): DRL focuses on reducing the frequency of an undesirable behavior. You reward the individual when they exhibit the unwanted behavior less frequently. For example, if a student frequently shouts out answers in class, you might reward them for speaking out less often. For this one, you need to start with a baseline. If the student in this example calls out currently 20 times a lesson- it would be challenging to go to 0. That is why you can set a goal of only calling out 18 times, and rewarding that behavior.

5. Differential Reinforcement of High Rates of Behavior (DRH): DHL focuses on increasing the frequency of the wanted behavior. This behavior already has to be in the student’s repertoire to use.

Differential Reinforcement is a versatile and effective strategy for behavior management, particularly in special education settings. By understanding its principles and applying them thoughtfully, you can help individuals make positive changes, develop new skills, and lead more fulfilling lives.

A great tool to help with some of these differential reinforcement strategies is using behavior charts. You can set the target behavior and the criteria needed to earn the reward. Check them out here.

Remember that patience, consistency, and empathy are your greatest allies in the process of behavior change. It may take time, but the rewards in terms of personal growth and improved quality of life are immeasurable.
