BCBA scenario questions usually test what to do next, what variable matters most, and which answer fits behavior-analytic reasoning under practical constraints.
A BCBA reviews data showing an increase in aggression after a new intervention began. Direct observation shows staff rarely prompt the replacement response and deliver reinforcement inconsistently. What should the BCBA do next?
Key explanation: The data cannot be interpreted as intervention failure until the plan is implemented correctly. The next step is staff retraining and integrity monitoring.
A caregiver asks a BCBA to treat severe feeding refusal. The BCBA has no training or supervised experience with feeding disorders. What is the most appropriate response?
Key explanation: The ethical priority is practicing within competence. The BCBA should refer, collaborate, or obtain appropriate supervision before providing services.
A teacher reports that a learner screams during independent work. No data have been collected and the function is unknown. What should the BCBA do first?
Key explanation: Intervention selection should be guided by assessment. The BCBA needs data about antecedents, consequences, and patterns before choosing procedures.
A learner answers correctly only when the instructor gives a full verbal prompt. The goal is independent responding. What should the BCBA adjust?
Key explanation: Prompt dependence is addressed by systematic fading and reinforcement for more independent responses.
Replace personality labels or internal-cause explanations with observable behavior, measurable context, and behavior-environment relations.
Open conceptMotivating operations alter reinforcer value and momentary response frequency; discriminative stimuli signal reinforcement availability.
Open conceptClassify consequences by whether behavior increases or decreases and whether a stimulus is added or removed.
Open conceptSelect measurement based on the dimension of behavior and the decision the team needs to make.
Open conceptInterpret graphs by considering level, trend, variability, overlap, immediacy, and implementation context before changing intervention.
