Applied Behavior Analysis: A Branch of Psychology or a Field of its Own?

ABA and Psychology: The Common Ground

ABA finds its roots in behaviorism, a school of psychology that focuses on the observable and measurable aspects of behavior. Many principles used in ABA, such as reinforcement, conditioning, and stimulus control, are directly borrowed from classic psychological theories. ABA utilizes these principles to bring about meaningful change in behavior, much like various psychological therapies.

The Divergence: Why A Separate Field? 

While ABA's origins lie in psychology, several factors have contributed to its evolution into a distinct field:

  1. Specialized Methodology: ABA adopts a highly systematic and data-driven approach that requires specific expertise. This methodology sets it apart from more generalized psychological practices.
  2. Target Audience: ABA has become particularly associated with autism spectrum disorders and developmental disabilities. Its emphasis on these areas has carved a unique niche that sometimes diverges from broader psychological concerns.
  3. Professional Recognition: With specialized certification and regulatory bodies like the Behavior Analyst Certification Board (BACB), ABA professionals have sought to define and regulate their practice independently from psychology.
  4. Ethical Considerations: ABA, at times, has been viewed as controversial, with debates over its methods and goals. These discussions might have driven a need to distinguish it from broader psychological practices.

Bridging or Breaking the Gap?

So, is ABA's divergence from psychology a means of breaking away or merely a way of highlighting its unique methodology and application? This question seems to have no straightforward answer.

On one hand, ABA's specialized focus justifies its distinction from general psychology. Its practitioners often undergo specific training, and the methodologies employed can be quite different from those used by psychologists. On the other hand, the foundational principles of ABA are steeped in psychology, and the goals of understanding, explaining, and altering behavior align closely with those of psychology. Some may argue that separating ABA from psychology risks losing the rich context and integrated understanding that psychology offers.


The relationship between ABA and psychology is complex and nuanced. While ABA may be seen as a specialized branch of psychology, its unique focus, methods, and regulatory landscape have also given it a distinct identity. This poses essential questions for both professionals and recipients of ABA services. Should ABA continue to forge its own path, or should there be a concerted effort to reconnect it with the broader field of psychology? How can the benefits of specialization be balanced with the integrative understanding that psychology offers?

These are questions worth exploring, and the answers may have profound implications for the future of ABA and the individuals it serves. Perhaps the debate itself, fostering dialogue and reflection, is what will ultimately lead to the most meaningful insights and progress.
