Which procedure is MOST appropriate for teaching a learner to discriminate between the presence and absence of the SD before providing assistance?
Answer: Progressive time delay
Progressive time delay gradually increases the wait between the SD and the prompt, systematically testing whether the learner can respond independently before assistance is provided.
A BCBA includes a maintenance probe schedule after skill mastery. What is the PRIMARY purpose?
Answer: To assess whether learned skills are retained over time without active training
Maintenance probes evaluate whether skills that met mastery criteria are durable over time, and help identify if booster sessions are needed.
When using PECS (Picture Exchange Communication System), Phase I focuses on teaching the learner to:
Answer: Spontaneously approach and hand a picture to a communicative partner
PECS Phase I establishes the physical exchange: the learner is taught to pick up a picture of a desired item and hand it directly to a communicative partner to receive the item.
A practitioner wants to reduce aggression maintained by attention. They decide to implement extinction (withhold attention) AND teach a functionally equivalent replacement behavior. This combined approach is referred to as:
Answer: Differential reinforcement of alternative behavior (DRA) with extinction
DRA + extinction pairs reinforcement of the replacement behavior with withholding the maintaining reinforcer for the problem behavior, making the alternative more effective.
Which type of prompt is considered LEAST intrusive and therefore preferred as a starting point in a least-to-most hierarchy?
Answer: Indirect verbal prompt
Indirect verbal prompts (e.g., 'What do you do next?') are the least intrusive because they do not specify the response and give the learner maximum opportunity for independent responding.
An ABA practitioner graphs behavior data and notices a celeration line trending in the wrong direction. The MOST appropriate first response is to:
Answer: Conduct a plan review and consider modifying the intervention
Data showing an undesirable trend is a signal for the treatment team to review the behavior intervention plan and make data-based modifications.
Which of the following BEST describes the 'blocking' antecedent intervention?
Answer: Physically preventing a response from being completed
Response blocking involves using physical contact or proximity to prevent the completion of a problem behavior, most commonly used with self-injurious or stereotypic behavior.
