Understanding the Functions of Behavior in ABA Therapy

ABA Therapy

Imagine your child throws a tantrum every time you ask them to turn off their tablet. Or maybe they hit their sibling when it’s time to share toys. At first glance, these behaviors might seem random or defiant—but in reality, every behavior serves a purpose.

In this guide, we’ll answer the question, “What are the 2 main functions of behavior in ABA?” explore how they connect to the broader framework of behavior analysis, and explain why this knowledge is key to supporting growth in individuals with autism and related needs. Let’s dive in!

What is ABA Therapy?

Applied Behavior Analysis (ABA) is a science-backed approach that focuses on improving socially significant behaviors by understanding how the environment influences them. ABA therapists use data-driven strategies to teach skills (like communication or self-care) and reduce behaviors that interfere with learning or safety.

Key principles include:

  1. Positive Reinforcement: Rewarding desired behaviors to increase their frequency.
  2. Antecedent-Behavior-Consequence (ABC) Model: Analyzing triggers (antecedents), actions (behaviors), and outcomes (consequences) to identify patterns.
  3. Individualization: Tailoring interventions to each person’s unique needs.

Organizations like the American Psychological Association endorse ABA, which is widely used to support individuals with autism, ADHD, and other developmental conditions.

Why Do Behavior Functions Matter in ABA?

Before addressing a behavior, ABA therapists ask: “What purpose does this action serve?” This question lies at the heart of Functional Behavior Assessment (FBA), a process used to identify the underlying reasons for behaviors.

Understanding the function of a behavior—its “why”—allows therapists to:

  1. Replace harmful behaviors with safer, more effective alternatives.
  2. Teach skills that meet the same need (e.g., communication instead of screaming).
  3. Adjust environments to reduce triggers.

Without knowing the function, interventions risk being ineffective or even counterproductive.

What are the 2 Main Functions of Behavior ABA?

In ABA, behaviors are not random; they serve specific purposes. The two main functions of behavior can be categorized as:

  1. Escape/Avoidance
  2. Access (to Tangibles or Attention)

These functions help explain why individuals engage in certain behaviors and guide therapists in developing strategies to promote positive behavior changes.

The Two Main Functions of Behavior in ABA

1. Escape/Avoidance

Escape or avoidance behaviors occur when an individual seeks to avoid or escape from situations, tasks, or demands that they find unpleasant or challenging. This function is common among individuals who may feel overwhelmed by specific stimuli or tasks.

Characteristics of Escape Behaviors

  • Tantrums: A child may throw a tantrum to avoid completing homework or chores.

  • Aggression: Some individuals may resort to aggressive behaviors to escape uncomfortable social situations.

  • Withdrawal: A child might withdraw from a group activity to avoid participating in something they dislike.

Understanding escape behaviors is crucial because they often indicate that an individual is struggling with anxiety, frustration, or sensory overload. By identifying these behaviors, therapists can develop interventions that help individuals cope with challenging situations more effectively.

Strategies for Addressing Escape Behaviors

To manage escape behaviors effectively, ABA practitioners often employ several strategies:

  • Functional Behavior Assessment (FBA): This assessment helps identify the triggers and antecedents that lead to escape behaviors. By understanding what prompts these behaviors, therapists can create tailored interventions.

  • Gradual Exposure: Gradually exposing individuals to challenging tasks can help them build tolerance and reduce anxiety over time. For example, if a child struggles with homework, a therapist might break the task into smaller, manageable parts.

  • Teaching Coping Skills: Equipping individuals with coping mechanisms—such as deep breathing exercises or self-advocacy skills—can empower them to face challenging situations without resorting to escape behaviors.

2. Access (to Tangibles or Attention)

The second main function of behavior is access, which refers to engaging in specific actions to obtain desired items, activities, or social interactions. This function can manifest in various ways:

Characteristics of Access Behaviors

  • Tantrums for Toys: A child may throw a tantrum in a store to get a toy they want.

  • Attention-Seeking: Some children may act out in class to gain attention from teachers or peers.

  • Requesting Activities: A child might refuse to complete chores unless they are promised a favorite activity afterward.

Access behaviors highlight the individual’s desire for reinforcement—whether it’s a tangible object, social interaction, or sensory experience. Understanding this function allows therapists to create strategies that redirect these behaviors toward more appropriate means of obtaining what they want.

Strategies for Addressing Access Behaviors

To address access-related behaviors effectively, ABA practitioners often use the following strategies:

  • Teaching Alternative Communication: For children who struggle to express their needs verbally, teaching them alternative communication methods—such as sign language or picture exchange systems—can help them request what they want appropriately.

  • Reinforcement Systems: Implementing reinforcement systems can encourage positive behavior. For instance, if a child completes their chores without complaint, they might earn points toward a desired activity.

  • Social Skills Training: Teaching social skills can help children learn how to interact appropriately with peers and adults. This reduces the need for attention-seeking behaviors by providing them with healthier ways to engage socially.

The Four Basic Behaviors in ABA

While we have discussed the two main functions of behavior in ABA, it’s also essential to understand the four basic behaviors that often relate to these functions:

  1. Sensory Stimulation

  2. Escape

  3. Attention-Seeking

  4. Access to Tangibles

These categories provide additional context for understanding why individuals engage in specific behaviors.

1. Sensory Stimulation

Sensory stimulation refers to behaviors individuals engage in for sensory input. This could include actions like rocking back and forth or flapping hands—behaviors often seen in individuals with sensory processing differences.

Addressing Sensory Needs

Therapists can help individuals meet their sensory needs through various strategies:

  • Sensory Breaks: Incorporating scheduled sensory breaks into daily routines allows individuals to engage in sensory activities without resorting to disruptive behaviors.

  • Fidget Tools: Providing fidget toys can help satisfy sensory-seeking needs while allowing individuals to remain engaged in other tasks.

2. Escape

As previously discussed, escape behaviors aim to avoid unpleasant situations. Recognizing these behaviors is crucial for developing effective interventions.

3. Attention-Seeking

Attention-seeking behaviors occur when individuals engage in actions designed to gain attention from others—whether positive or negative.

Addressing Attention-Seeking Behaviors

To manage attention-seeking behaviors effectively:

  • Positive Reinforcement for Appropriate Behavior: Reinforcing positive social interactions can reduce the need for disruptive attention-seeking actions.

  • Scheduled Attention: Providing regular one-on-one time can fulfill an individual’s need for attention without resorting to negative behavior.

4. Access to Tangibles

Access-related behaviors revolve around obtaining desired items or activities. Understanding this function allows therapists to create interventions that teach appropriate ways of requesting and obtaining what one desires.

Conclusion: Take Action Towards Positive Change

Understanding “What are the 2 main functions of behavior ABA?” is crucial for anyone involved in supporting individuals with behavioral challenges. By recognizing escape/avoidance and access as fundamental behavioral functions, parents and caregivers can better understand their loved ones’ actions and responses.
