Applied Behavior Analysis and Functional Analysis: A Comprehensive Overview

Updated: Jan 17



Functional Analysis, applied behavior analysis

Applied Behavior Analysis (ABA) and Functional Analysis are two critical concepts in behavioral psychology that have significantly influenced therapies and interventions for individuals, particularly those with a diagnosis of Autism Spectrum Disorder (ASD). Let's delve into these two concepts and explore their significance.


What is Applied Behavior Analysis (ABA)?

Applied Behavior Analysis (ABA) is a type of therapy rooted in the principles of behaviorism and learning theory. It is most commonly known for treating individuals with a diagnosis of ASD, but its applications extend to various other areas as well (source: WebMD).


ABA therapy applies our understanding of how behavior works to real situations with the aim to increase behaviors that are helpful and decrease behaviors that are harmful or affect learning (source: Autism Speaks). The therapy focuses on improving specific behaviors, such as social skills, communication, reading, and adaptive learning skills like fine motor dexterity, hygiene, grooming, domestic capabilities, punctuality, and job competence (source: Psychology Today).


One of the critical aspects of ABA is its focus on socially significant behaviors. This means that the therapy aims to help individuals perform behaviors that will enhance their quality of life and those around them.


What is Functional Analysis?

Functional Analysis, on the other hand, is a specific methodology within ABA that aims to identify the function or purpose of a person's behavior to develop a more effective behavior intervention plan (source: ThinkPsych).


A functional analysis involves the direct manipulation of antecedents (what happens before a behavior occurs) and consequences (what happens after the behavior) to determine why a specific behavior occurs (source: Association for Science in Autism Treatment). This process allows for a deeper understanding of the behavior in question and ensures that the intervention is tailored to the individual's specific needs.


For example, if a child shows a particular behavior when they want attention, the functional analysis would identify this motivation (attention-seeking) as the function of the child's behavior. This information would then be used to develop an intervention strategy that teaches the child more appropriate ways to seek attention (source: Autism Parenting Magazine).


The Connection Between ABA and Functional Analysis

ABA and Functional Analysis are intrinsically linked, with Functional Analysis being a key component of ABA. By understanding the function or purpose behind an individual's behavior through Functional Analysis, ABA therapists can develop targeted strategies to promote positive behavior change.


ABA and Functional Analysis together provide a powerful toolset for understanding and shaping behavior, contributing to improved social interactions, learning new skills, and maintaining positive behaviors for individuals, particularly those with a diagnosis of Autism Spectrum Disorder (ASD) (source: APA).


These therapeutic approaches are grounded in scientific research and evidence-based practice, underscoring their effectiveness and the significant role they play in behavioral psychology. They offer a beacon of hope for many individuals and families, illuminating the path towards improved communication, learning, and overall quality of life.
