BCBA Philosophical Foundations Practice Questions
Domain A is the smallest section of the BCBA exam, but its ideas run through every other domain. Expect questions that ask you to recognize a philosophical assumption in a short scenario, spot an explanatory fiction, or match a description to one of the seven dimensions of applied behavior analysis.
What Domain A covers
The 6th Edition Test Content Outline lists 5 tasks in this domain. Baseline has practice questions mapped to every one of them.
- A.1Goals of behavior analysis as a science: description, prediction, control
- A.2Philosophical assumptions: selectionism, determinism, empiricism, parsimony, pragmatism
- A.3Explaining behavior from a radical behaviorist perspective
- A.4Behaviorism vs. EAB vs. ABA vs. professional practice
- A.5Dimensions of applied behavior analysis
What to master
- The levels of scientific understanding — description, prediction, and control — and what kind of evidence reaches each one.
- The assumptions of science (determinism, empiricism, experimentation, replication, parsimony, philosophic doubt) plus selectionism and pragmatism.
- How radical behaviorism treats private events, and why mentalistic explanations are circular.
- The seven dimensions of ABA from Baer, Wolf, and Risley: applied, behavioral, analytic, technological, conceptually systematic, effective, and generality.
Common traps
- Confusing "applied" (socially significant behavior) with "conducted in an applied setting".
- Treating radical behaviorism as if it ignores thoughts and feelings — it analyzes them as behavior.
- Mixing up parsimony (simplest adequate explanation first) with philosophic doubt (continually questioning findings).

1. A journal article describes a token economy in enough detail — token delivery rules, exchange rates, and staff scripts — that another trained practitioner could implement it exactly as written. Which dimension of applied behavior analysis does this best illustrate?
- Technological
- Analytic
- Conceptually systematic
- Generality
Show answer and explanation
Answer: A. Technological
Technological means procedures are described clearly and completely enough to be replicated. Conceptually systematic refers to linking procedures to basic principles; analytic refers to demonstrating a functional relation; generality refers to effects lasting over time or spreading to other settings and behaviors.
2. A teacher says, "Liam hits other kids because he's frustrated." From a radical behaviorist perspective, what is the main problem with this explanation?
- Frustration can't be directly observed, so the hitting itself can't be reliably measured or recorded
- It violates parsimony, because hitting is too complex to be explained by a single variable
- It is an explanatory fiction that names the behavior rather than the environmental variables that control it
- Radical behaviorism doesn't consider private events such as frustration to be behavior at all
Show answer and explanation
Answer: C. It is an explanatory fiction that names the behavior rather than the environmental variables that control it
"Frustration" is inferred from the same hitting it is meant to explain, so the reasoning is circular — an explanatory fiction. Radical behaviorism does treat private events as behavior, so the claim that they aren't behavior is incorrect; the issue is that the explanation points away from the antecedents and consequences we can actually change.
