Exam Set 1
Question 1
Joan is a BCBA who works in a preschool classroom for children with autism and related
developmental disabilities. While getting a manicure, she reads a tabloid article claiming that
classroom hamsters improve children's social skills. Without reviewing any peer-reviewed
,research, Joan purchases a hamster and immediately incorporates daily hamster-interaction
activities into all students' treatment plans.
Which scientific attitude did Joan fail to demonstrate?
A. Philosophical doubt
B. Parsimony
C. Empiricism
D. Experimentation
Correct Answer:
C. Empiricism
Expert Rationale:
Empiricism refers to relying on objective observation and scientific evidence when making
decisions. Joan based her intervention on information from a tabloid rather than data obtained
through systematic research or direct observation.
Behavior analysts are expected to make treatment decisions using evidence-based practices
supported by scientific literature and data collection.
Why the other options are incorrect:
• A. Philosophical doubt involves questioning findings and maintaining healthy
skepticism. Although Joan also failed to question the claim, her primary violation was
implementing an intervention without evidence.
• B. Parsimony involves selecting the simplest explanation before assuming complex
causes.
• D. Experimentation refers to manipulating variables to demonstrate functional relations.
BCBA Exam Tip: Whenever an intervention is selected based on opinion, anecdotes, social
media, or popular media instead of scientific evidence, empiricism is typically the best answer.
Question 2
During a supervision meeting, a trainee asks which philosophical approach to behavior science
acknowledges that thoughts, feelings, and other private events can influence behavior even
though they cannot be directly observed.
, Which approach should the BCBA identify?
A. Radical behaviorism
B. Experimental analysis of behavior
C. Ontogeny
D. Methodological behaviorism
Correct Answer:
A. Radical behaviorism
Expert Rationale:
Radical behaviorism, developed by B. F. Skinner, recognizes both observable behavior and
private events (thoughts, emotions, sensations) as legitimate subjects of behavioral analysis.
Private events are considered behavior that occurs within the skin and are influenced by the same
environmental variables that affect public behavior.
Why the other options are incorrect:
• B. Experimental analysis of behavior (EAB) is a research methodology.
• C. Ontogeny refers to behavioral development across an individual's lifetime.
• D. Methodological behaviorism generally excludes private events from scientific study.
BCBA Exam Tip: Questions involving thoughts, emotions, and feelings as behavioral
phenomena often point toward radical behaviorism.
Question 3
Jessica routinely places her dog, Lucky, in his crate before leaving for yoga class. One day,
Jessica picks up her yoga mat, and Lucky immediately walks into his crate independently.
Jessica praises him and delivers a treat. After several similar occurrences, Lucky consistently
enters his crate whenever Jessica picks up the yoga mat.
Which concept best explains Lucky's behavior?
A. Generality
B. Pragmatism
