Old Truths, New Ideas: The Past, Present, and Future of ABA

Abstract

The Principles of Behavior were uncovered through meticulous laboratory experiments by a select group of scientists working with non-human subjects. These foundational studies revealed that behavior follows lawful and predictable patterns that can be influenced through the precise application of behavioral contingencies. Remarkably, when these same principles were applied to significant human behaviors in natural environments, they produced similar, reliable effects—giving rise to what we now know as Applied Behavior Analysis (ABA).

Since the 1960s, behavior analysis has transformed countless lives for the better. The scientist-practitioner model has been central to this progress, maintaining a focus on evidence-based practice and generating a robust body of research that shows ABA therapy is technical, replicable, conceptually systematic, effective, and capable of promoting generalization across contexts.

Today, behavioral science stands as a powerful and effective discipline. The past decade has seen a rapid expansion in the number of behavior analysis programs, increased funding opportunities, and rising demand for ABA services. But is this rapid growth entirely positive?

This presentation will explore that question by examining emerging ideas, approaches, and practices gaining traction in the field of behavior analysis. It will also discuss the critical questions we should ask to assess the functional value of these new treatment methods and the ongoing need for rigorous clinical practice standards to ensure we continue to advance as a true science of human behavior.
