The dimensions of Applied Behavior Analysis (ABA) were first outlined in a now famous article published in the Journal of Behavioral Analysis in 1968. This article carefully described the characteristics of interventions based on ABA and distinguished it from experimental analysis of behavior. Before we discuss the dimensions of ABA in detail, however, let’s ground ourselves by exploring what we mean by behavior.
What is behavior?
Understanding human behavior is central to the science of ABA. One of the core dimensions of applied behavior analysis is that behavior must be both observable and measurable. In other words, for something to qualify as behavior, it must be something you can see, count, and objectively describe.
It’s easy to associate “behavior” with actions that are disruptive or undesirable — like yelling or hitting — but behavior encompasses much more. Smiling at a friend, tying your shoes, or asking a question are all examples of behavior, too. ABA professionals focus on all kinds of actions, whether they’re positive, neutral, or problematic, because every behavior has meaning and can be shaped through intentional strategies.
A common misconception is confusing emotional states or internal experiences with behavior. Words like “anxious” or “happy” describe how someone feels, but they are not behaviors in themselves. These states can’t be directly observed or consistently measured across different observers. For example, five people might interpret the same facial expression differently — each with their own guess about how the person feels.
Instead, ABA focuses on what can be seen and agreed upon. If someone is smiling, clapping, or pacing, those are observable behaviors. You can count how often they occur and determine whether specific interventions are effective in increasing or decreasing them.
This emphasis on observable and measurable behavior is essential to all dimensions of applied behavior analysis. It ensures clarity in defining target behaviors and evaluating the success of behavioral interventions. Without it, ABA strategies risk being vague and ineffective — leaving teams unsure if progress is being made.

7 dimensions of ABA
ABA is the science dedicated to understanding and improving human behavior. At its core, ABA applies research-based principles to change socially significant behaviors — those that impact a person’s daily life in meaningful ways. By analyzing the relationship between behavior and the environment, ABA helps identify why individuals behave in certain ways and how those behaviors can be supported or changed.
A foundational part of this science lies in the seven dimensions of applied behavior analysis. These dimensions define the essential qualities of effective ABA practice and ensure that interventions are both ethical and evidence-based. Whether you’re a seasoned professional or preparing for your Registered Behavior Technician (RBT) certification, knowing these dimensions is key to understanding how ABA works in real-world settings.
The seven dimensions include: Applied, Behavioral, Analytic, Technological, Conceptual, Effective, and Generality. For those studying for their RBT certification, the acronym GET A CAB is helpful for remembering the different dimensions of applied behavior analysis, as well.
Understanding the dimensions of applied behavior analysis gives us a framework for making sure that ABA services are purposeful, data-driven, and centered on improving quality of life. In the sections that follow, we’ll break down each dimension and explore how they come to life in everyday practice.
Generality
The intervention is designed to operate in new environments and continue after formal treatment ends.
An example is teaching someone to brush their teeth in a clinic setting for 5 weeks who then brushes their teeth at home before bed each night for years to come.
Effective
An intervention produces robust and important effects.
An example is teaching a child who engages in biting their hands behavior to bite a rubber chew stick instead.
Technological
The intervention is described well enough that it can be replicated by others and produce the same results.
An example would be a written protocol for teaching handwashing to a specific individual that is followed by multiple trainers.
Analytic
You can objectively demonstrate that the intervention caused the change in behavior.
An example would be after a child receives specific training to give a picture of a toy to receive a toy car, the child will find the picture of the toy car spontaneously and give it to an adult and wait for receipt of the toy car.
Conceptual
The intervention is based on a specific theory and not from a random collection of disassociated activities.
An example of this is a child recognizing various shapes, forms, colors, and positions of objects, called “visual discrimination.”
Applied
The intervention deals with a problem of social importance.
An example of this would be using reinforcement to increase the number of times a child responded to the request to “come here” when in a busy park.
Behavioral
The intervention and resulting behavior change can be observed and measured and thus be validated.
An example of this is when a child who would previously take an adult by the hand to the pantry for a snack can now use words to request a snack.
