Types of Extinction in ABA Therapy

Leave a Comment / By Staff / June 23, 2024

In the field of Applied Behavior Analysis (ABA), extinction is a powerful technique used to decrease or eliminate undesirable behaviors while promoting the development of more appropriate ones. By understanding the definition and importance of extinction, parents and caregivers can gain insight into how this technique can be effectively implemented to support individuals with autism and other behavioral challenges.

Definition of Extinction

Extinction, within the context of ABA, refers to the strategic and intentional process of ceasing to reinforce a behavior that was previously reinforced. It is essential to note that extinction is not simply ignoring a behavior; it involves actively withholding the reinforcer that previously maintained the behavior. This deliberate change in reinforcement is aimed at reducing or eliminating the targeted behavior over time.

For example, if a child engages in tantrum behavior to gain attention, extinction would involve no longer providing attention as a consequence for the tantrum. By consistently not reinforcing the behavior, the child learns that the tantrum no longer leads to the desired outcome.

Importance of Extinction

Extinction is an important technique in ABA because it helps to reduce or eliminate behaviors that may interfere with learning, social interactions, and daily functioning. By removing the reinforcing consequences associated with unwanted behaviors, individuals are motivated to seek alternative, more appropriate behaviors that can fulfill their needs.

Extinction can also promote the development of new skills and behaviors. When an undesired behavior is no longer effective in producing the desired outcome, individuals are encouraged to explore and engage in alternative behaviors that may lead to more positive reinforcement.

It is crucial to remember that while extinction can be an effective strategy, the physical, psychological, and emotional safety of learners must always be a priority. ABA practitioners emphasize the need to respond to emotional needs first and ensure that actions convey understanding and respect. Extinction should be implemented thoughtfully and in conjunction with other behavior modification techniques, such as positive reinforcement and teaching replacement behaviors.

By understanding the definition and importance of extinction in ABA, parents and caregivers can make informed decisions about its application and actively support the development of more adaptive behaviors in individuals with autism and other behavioral challenges.

Types of Extinction Techniques

In the field of Applied Behavior Analysis (ABA), there are three main types of extinction techniques used to reduce or eliminate previously reinforced behaviors. These techniques include positive reinforcement extinction, automatic reinforcement extinction, and negative reinforcement extinction.

Positive Reinforcement Extinction

Positive reinforcement extinction involves removing the reinforcing stimulus that previously maintained a behavior. This means that the behavior is no longer followed by a positive consequence, such as praise, attention, or a desired item. By withholding the positive reinforcement, the behavior becomes less likely to occur in the future.

For example, if a child engages in tantrums to gain attention from a parent, using positive reinforcement extinction would involve not providing attention during the tantrum. Over time, if the tantrum no longer leads to attention, the child may learn that the behavior is ineffective and gradually decrease its occurrence.

Automatic Reinforcement Extinction

Automatic reinforcement extinction focuses on reducing behaviors that are self-reinforcing. These behaviors are maintained by the sensory or physical consequences they produce, rather than by external reinforcement from others. In this case, the goal is to eliminate or reduce the availability of the sensory or physical reinforcement associated with the behavior.

For instance, if a child engages in repetitive hand-flapping behavior to produce sensory stimulation, employing automatic reinforcement extinction would involve preventing or reducing the availability of the sensory stimulation. This could be done by redirecting the child’s attention to alternative activities or providing sensory input in more appropriate ways.

Negative Reinforcement Extinction

Negative reinforcement extinction targets behaviors that are maintained by the removal or avoidance of aversive stimuli. In negative reinforcement, the behavior leads to the termination or avoidance of something unpleasant. With negative reinforcement extinction, the aversive stimulus is no longer removed or avoided when the behavior occurs, thereby reducing the behavior’s likelihood.

For example, a child engages in escape-maintained behaviors to avoid participating in academic tasks. In this scenario, the child might display behaviors such as crying, refusing to comply, or physically leaving the learning area when presented with academic demands. These behaviors are negatively reinforced because they allow the child to escape or avoid the aversive task, such as completing math problems or reading assignments.

To address this behavior using negative reinforcement extinction, ABA therapists would implement a systematic approach where the child is required to complete the academic task without allowing escape or avoidance. For instance, the therapist may prompt the child to begin the task and provide minimal attention or reaction to any escape attempts (e.g., crying, attempting to leave). Over time, as the child learns that engaging in escape-maintained behaviors no longer results in the removal of the academic task (the aversive stimulus), the frequency and intensity of these behaviors should decrease.

It’s important to note that extinction should not be used as a standalone intervention. Instead, it should be complemented with positive approaches to create a comprehensive behavior modification plan. Additionally, for individuals with self-injurious behaviors or aggressive behaviors, other strategies may be more appropriate than extinction. Consulting with an ABA professional or ABA center for autism can provide further guidance on implementing extinction techniques effectively.

Considerations for Implementing Extinction

When implementing extinction as part of Applied Behavior Analysis (ABA), it is crucial to consider the emotional safety of the learner and engage in strategic planning. Ignoring a learner’s needs, especially those who may have experienced trauma or struggle with effective communication, can lead to feelings of neglect and potentially increase challenging behaviors. Therefore, it is important to prioritize the physical, psychological, and emotional safety of learners throughout the process.

Learner's Emotional Safety

The emotional well-being of the learner should always be a top priority when considering the application of extinction in ABA. It is essential to respond to the emotional needs of the learner and ensure that interactions convey understanding and respect. Each learner is unique, and their emotional reactions to extinction procedures may vary. ABA professionals should strive to create a supportive and nurturing environment that fosters trust and promotes emotional safety.

Instead of solely focusing on extinguishing unwanted behaviors, it is important to shift the focus towards understanding the underlying needs of the learner. By identifying these needs, ABA practitioners can develop strategies to teach replacement skills that allow learners to access what they seek in a more appropriate manner. This approach promotes positive reinforcement and helps address the root causes of challenging behaviors.

Strategic Planning for Extinction

Implementing extinction thoughtfully requires strategic planning. It involves carefully considering the specific behaviors targeted for extinction and developing a comprehensive plan to address them. It is important to reflect on the outcomes of the extinction process and adjust strategies as needed, always prioritizing the learner’s well-being.

Strategic planning for extinction includes two key components: the gradual removal of reinforcers and the teaching of replacement behaviors. Gradual removal of reinforcers involves reducing or eliminating the reinforcement that previously maintained the targeted behavior. This process helps to weaken the association between the behavior and the desired outcome.

Simultaneously, teaching replacement behaviors is crucial to ensure that the learner has alternative strategies to obtain the desired outcomes. By teaching appropriate and functional replacement behaviors, ABA practitioners empower learners to engage in more adaptive and socially acceptable actions.

By approaching extinction with careful consideration for the learner’s emotional safety and implementing strategic planning, ABA professionals can effectively address problematic behaviors. It is important to remember that extinction should not be used alone and should be combined with positive approaches. For children with self-injurious behaviors and aggressive behaviors, extinction may be less likely to be suggested in ABA practices. By combining extinction with other techniques, such as reinforcement and shaping, ABA therapy can promote the development of more adaptive and appropriate responses in individuals with developmental disabilities and other disorders.

Prioritizing the emotional well-being of learners and maintaining a thoughtful strategic approach ensures that extinction is implemented in a manner that is both effective and respectful of the individual’s needs.
