1. Behavior:
Behavior refers to any observable and measurable action or activity exhibited by an individual.
It includes a wide range of actions, both overt (visible) and covert (internal or private), such as:
- physical movements
- vocalizations
- thoughts
- emotions
- physiological processes
Behavior can be influenced by various factors, including:
- genetics
- environment
- learning experiences
- internal states
Example:
In a social setting, behavior can include actions such as talking, listening, smiling,
shaking hands, making eye contact, or nodding.
For more on how these behaviors are analyzed, see
real-world ABA case studies
and verbal operants in ABA.
2. Response:
A response is a specific and observable behavior exhibited by an individual in reaction to a particular stimulus or situation.
It is a measurable unit of behavior that can be analyzed and described in terms of its:
- topography (physical form)
- frequency
- duration
- intensity
- other relevant dimensions
Responses can be voluntary or involuntary and may be influenced by both internal and external factors.
For examples of stimulus–response relationships, see
stimulus control in ABA.
Example:
If we are using the behaviors from the social setting in the above example, then a segment of the talking exchange is a response —
a moment where someone smiles in response to a stimulus, a specific greeting where people shake hands,
or when someone makes eye contact following their name being called.
These are instances of the behavior following a prompt.

Please note:
The terms “behavior” and “response” are often used interchangeably, and their precise definitions and usage can vary depending on the context and field of study.
Learn more in study strategies for the BCBA exam.
3. Response Class:
A response class is a set of behaviors that share similar functions or serve the same purpose in a given context.
These behaviors may differ in their topography (physical form) but have common effects on the environment.
(see related 6th Edition updates)
Responses within a response class are functionally equivalent because they:
- produce similar consequences
- serve the same goal
Example:
In the context of communication, a response class can include behaviors such as:
- speaking
- writing
- using sign language
- using gestures
Although the topography of these behaviors varies, they all serve the purpose of conveying information
or expressing thoughts.

and multiple control in verbal behavior.
An individual’s behavioral repertoire is all the skills and behaviors this individual has demonstrated over time that he is capable of performing.

In applied behavior analysis, environment refers to stimulus conditions that are internal and external to an individual.
