Key Behavior Functions in ABA Therapy

Understanding why certain behaviors happen is essential in Applied Behavior Analysis (ABA). Every action has a reason, or “function,” that drives it. These behavior functions explain what a person is trying to achieve through their actions, whether it’s getting attention, avoiding something unpleasant, or seeking comfort. 

Identifying the purpose behind a behavior makes it possible to create effective strategies to encourage positive actions and reduce challenging ones.

What Are Behavior Functions in ABA?

In the practice of ABA, behavior is often categorized into distinct functions, such as avoidance, access, attention, and sensory. By identifying these functions, therapists and caregivers can gain insights into why certain behaviors occur, which is instrumental in designing targeted intervention strategies for individuals with autism or other developmental disorders.

That said, here are the four functions of behavior in ABA:

Understanding these behavior functions helps in replacing maladaptive behaviors with more adaptive responses, consequently enhancing the individual’s quality of life and social interactions.

Functional Behavior Assessment

Integral to the ABA therapy process, a Functional Behavior Assessment (FBA) serves as a foundational step in understanding and addressing problematic behaviors. By systematically analyzing the antecedents, behaviors, and consequences surrounding the target behavior, clinicians can decipher the underlying function driving the behavior.

This assessment provides valuable insights into the triggers that elicit the behavior, the purpose it serves for the individual, and the potential reinforcers that maintain the behavior. 

Armed with this comprehensive understanding, therapists can tailor behavior intervention plans that are tailored to the specific function of the behavior, increasing the effectiveness of the intervention and promoting positive behavior change.

Additional Behavior Functions

Apart from the primary functions of behavior, there are also additional behavior functions that play a crucial role in shaping individuals’ actions and responses.

One of them is socially mediated positive reinforcement. This occurs when an individual exhibits behaviors like crying, hitting, biting, kicking, or screaming to receive positive reinforcement, such as obtaining something they desire. 

The reinforcement in this case usually involves interactions with others, where the behavior is reinforced through social exchange.

On the flip side, we have socially mediated negative reinforcement which involves an individual engaging in behaviors like self-injury (e.g., biting their hand) to avoid or escape from undesired tasks or situations. The behavior is reinforced by social elements, often involving interactions with others that contribute to the maintenance of the behavior.

Automatic positive reinforcement is another additional behavior function in ABA. In this case, the individual engages in behaviors like self-stimulatory behavior (e.g., rocking, verbal stimming) to self-stimulate and experience pleasure. 

Unlike socially mediated positive reinforcement, this function does not require external input or interaction with others to reinforce the behavior.

Contrary to this is the so-called automatic negative reinforcement, which is an important aspect to consider in behavior analysis. This pertains to behaviors like self-injury (e.g., biting) which could indicate distress or pain in individuals, suggesting a form of automatic negative reinforcement.

Understanding these additional behavior functions, alongside the primary functions of behavior in ABA, is crucial for developing comprehensive treatment plans and interventions that address the specific needs of individuals with autism spectrum disorders.

The Bottom Line

Understanding behavior functions in ABA is like finding the key to unlocking why people act the way they do. By identifying whether a behavior is driven by attention, escape, access to something, or sensory needs, we can help shape more positive actions and responses.
