Differential Reinforcement of Alternative Behavior: A Powerful Tool for Behavior Change

Differential reinforcement of alternative behavior (DRA) is a behavior modification technique that aims to replace unwanted behaviors with more desirable ones. This technique is commonly used in various settings, including clinical psychology, education, and even animal training.

How does DRA work?

The core principle of DRA is reinforcing a desired behavior while simultaneously ignoring or withholding reinforcement for the undesired behavior. This creates a clear incentive for the individual to choose the alternative behavior, as it leads to positive consequences.

Think of it like this: Imagine a child who constantly calls out in class for attention. Instead of simply reprimanding the child, the teacher implements DRA. They might:

• Reinforce the child's hand-raising behavior with verbal praise and a small reward.
• Ignore the child's calling out, effectively removing the attention that was previously reinforcing the undesired behavior.

The Key Elements of DRA

Several key elements contribute to the effectiveness of DRA:

1. Identifying the target behavior: The first step is to clearly define the behavior you want to reduce or eliminate. In our example, the target behavior is "calling out in class."

2. Choosing an appropriate alternative behavior: The alternative behavior should be socially acceptable, achievable, and something the individual is capable of performing. In our example, the alternative behavior is "raising a hand."

3. Providing consistent reinforcement: The reinforcement should be contingent upon the occurrence of the alternative behavior and should be delivered immediately following the desired action. Consistent reinforcement is crucial for establishing and maintaining the new behavior.

4. Ignoring the target behavior: Ignoring the target behavior, known as extinction, is essential to reduce its frequency. The individual should not receive any attention or reinforcement for engaging in the undesired behavior.

The Benefits of DRA

DRA offers several benefits over other behavior modification techniques:

• Focuses on positive behavior: Instead of punishing unwanted behavior, DRA emphasizes the development and reinforcement of positive alternatives.

• Builds on existing strengths: The chosen alternative behavior often builds on existing skills and abilities, making it more likely to be successful.

• Teaches new skills: DRA can be a valuable tool for teaching new behaviors and expanding an individual's repertoire of positive responses.

Real-world Applications of DRA

DRA has numerous applications in various settings:

• Education: Reducing disruptive behavior in classrooms, promoting on-task behavior, and teaching social skills.

• Clinical Psychology: Treating anxiety disorders, managing self-injurious behavior, and reducing aggression.

• Animal Training: Teaching pets new tricks, eliminating undesirable behaviors like barking or chewing, and promoting desirable behaviors like waiting patiently for a treat.

Research on DRA:

Numerous studies have demonstrated the effectiveness of DRA in reducing unwanted behaviors and promoting desired alternatives.

For example, a study by Alberto and Troutman (2009) investigated the use of DRA in reducing disruptive behavior in elementary school students. They found that DRA was significantly more effective than ignoring the disruptive behavior alone.

Dr. David H. Barlow (2013), a prominent researcher in the field of clinical psychology, emphasized the importance of DRA as a key element in effective treatment of anxiety disorders. He highlighted its role in replacing anxious avoidance behaviors with more adaptive coping mechanisms.

Challenges and Limitations:

While DRA is a powerful tool, there are potential challenges and limitations to consider:

• Initial increase in undesired behavior: Initially, the target behavior may increase in frequency or intensity before it starts to decrease. This is known as an extinction burst, and it can be frustrating, but it is often a temporary phenomenon.

• Difficulty in ignoring the target behavior: Ignoring the target behavior can be challenging, especially in situations where it is severe or disruptive.

• Finding an appropriate alternative behavior: Choosing a suitable alternative behavior that is engaging and achievable for the individual can be difficult.

Practical Tips for Implementing DRA:

• Start with a clear definition of the target behavior: Define the specific behavior you want to reduce.
• Choose an appropriate alternative behavior: Identify a behavior that is socially acceptable and that the individual can perform.
• Provide consistent reinforcement: Reward the alternative behavior immediately and consistently.
• Ignore the target behavior: Do not give any attention or reinforcement to the undesired behavior.
• Be patient and persistent: DRA takes time and patience to show results.

Conclusion

Differential reinforcement of alternative behavior is a versatile and evidence-based behavior modification technique that can effectively reduce unwanted behaviors and promote desired alternatives. Understanding the principles and applying the practical tips described in this article can help individuals, educators, therapists, and animal trainers utilize DRA effectively in various contexts.
