BACB Behavior Change Procedures 1 — Questions and Answers
Question 1: Which prompting strategy fades prompts from the most intrusive to least intrusive over time?
- Most-to-least prompting (Correct answer)
- Least-to-most prompting
- Simultaneous prompting
- Time delay
Correct answer: Most-to-least prompting
Most-to-least prompting begins with the highest level of assistance and systematically reduces prompt intrusiveness as the learner acquires the skill.
Question 2: What is the key feature of a 'time delay' prompting procedure?
- Adding a pause between the SD and a controlling prompt to allow the learner to respond independently (Correct answer)
- Presenting the most intrusive prompt immediately after the SD
- Fading the physical properties of a prompt
- Using errorless teaching with no delay
Correct answer: Adding a pause between the SD and a controlling prompt to allow the learner to respond independently
Time delay inserts a brief pause between the SD and the controlling prompt, giving the learner an opportunity to respond independently before the prompt is delivered.
Question 3: Which chaining method teaches all steps of a task simultaneously, with the trainer providing assistance on each step during every session?
- Forward chaining
- Backward chaining
- Total task chaining (Correct answer)
- Interrupted chain
Correct answer: Total task chaining
Total task chaining presents every step of a task analysis in each session, with the trainer prompting steps as needed so the learner experiences the complete chain every trial.
Question 4: Backward chaining begins instruction at which step of a task analysis?
- First step
- Middle step
- Last step (Correct answer)
- Hardest step
Correct answer: Last step
Backward chaining begins teaching at the final step of the task analysis, so the learner always experiences task completion as the immediate reinforcer.
Question 5: Which differential reinforcement procedure reinforces a behavior that is physically incompatible with the problem behavior?
- DRO
- DRL
- DRI (Correct answer)
- DRA
Correct answer: DRI
Differential reinforcement of incompatible behavior (DRI) reinforces a behavior that cannot occur at the same time as the problem behavior.
Question 6: What is the primary mechanism of functional communication training (FCT)?
- Punishing problem behavior and ignoring communication
- Teaching a communicative response that produces the same reinforcement as the problem behavior (Correct answer)
- Using extinction alone to reduce problem behavior
- Providing noncontingent reinforcement to eliminate the MO
Correct answer: Teaching a communicative response that produces the same reinforcement as the problem behavior
FCT replaces problem behavior with a communicative response that contacts the same functional reinforcer, making problem behavior less efficient.
