Mentalism in Applied Behavior Analysis (ABA)
Mentalism refers to explaining behavior by assuming the existence of internal mental states or processes as the root cause of that behavior. Unlike radical behaviorism, which addresses private events within a behavioral framework, mentalism relies on concepts that are not directly observable or measurable.

Key Forms of Mentalism
Hypothetical Constructs
Hypothetical constructs are theoretical concepts based on internal processes that cannot be observed or measured directly. These ideas often include abstract qualities such as free will, self-esteem, pride, dedication, and intelligence. While commonly used to explain behavior, these constructs lack empirical validation.
(Top BCBA study materials)
Example:
Saying someone acted on “intuition” suggests an internal, unmeasurable process that influenced the behavior.
Explanatory Fictions
Explanatory fictions are circular explanations that rename the behavior being observed without offering a functional cause. They often rely on vague or abstract terms like “intelligence” or “cognitive awareness,” which do not contribute to identifying environmental variables responsible for behavior.
(ABA case studies)
Example:
Zoe gets high grades because she’s intelligent.
This explanation does not account for measurable conditions such as study time, reinforcement, or instructional quality.
Circular Reasoning
Circular reasoning occurs when the cause and effect are defined in terms of each other. The explanation loops without identifying external, functional variables affecting behavior.
(Lessons from behavior analysis)
Example:
John is a good man because he follows his intuition.
We know he follows his intuition because he is a good man.
Why It Matters in ABA
In Applied Behavior Analysis, explanations of behavior must be based on observable, measurable, and verifiable data. Mentalistic explanations fail to meet this standard and may hinder the development of effective interventions.
