BCBA Practice Questions

Master the Behavior Change Procedures Domain

Test your knowledge in the Behavior Change Procedures domain with these 5 practice questions. Each question is designed to help you prepare for the BCBA certification exam with detailed explanations to reinforce your learning.

Question 1

A client with autism is learning to use a communication device to request items. The behavior analyst notices the client is only using the device when prompted and not spontaneously. What is the best strategy to increase spontaneous use of the device?

A) Increase the number of prompts

B) Implement a time delay procedure

C) Use a physical prompt hierarchy

D) Conduct a preference assessment

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: Implementing a time delay procedure can help fade prompts and encourage spontaneous use by allowing the client time to initiate communication independently. OPTION A: Increasing the number of prompts may lead to prompt dependency. OPTION B: A physical prompt hierarchy is not relevant to increasing spontaneous communication. OPTION C: Conducting a preference assessment does not directly address spontaneous use of the communication device.

Question 2

A client often refuses to complete morning routine tasks. The behavior analyst decides to use a high-probability request sequence. Which description best fits this procedure?

A) Gradually increasing task difficulty over time

B) Presenting a series of easy requests followed by a challenging one

C) Providing choices between tasks

D) Using visual schedules to outline tasks

Show Answer & Explanation

Correct Answer: B

Explanation: A high-probability request sequence involves presenting a series of requests with a high likelihood of compliance (easy tasks) followed by a request with a lower likelihood of compliance (challenging task) to increase compliance with the challenging request.

Question 3

A behavior analyst is using a fixed-interval schedule of reinforcement to increase a client's independent work behavior. What is a common effect of this schedule on behavior patterns?

A) A steady, high rate of responding

B) A scalloped pattern of responding

C) A low, variable rate of responding

D) A burst of responding at the beginning of the interval

Show Answer & Explanation

Correct Answer: B

Explanation: CORRECT: A fixed-interval schedule often produces a scalloped pattern, where responding increases as the interval ends. OPTION A: A steady, high rate is more typical of variable-ratio schedules. OPTION C: A low, variable rate is not characteristic of fixed-interval schedules. OPTION D: A burst at the beginning is not typical; responding usually increases towards the end of the interval.

Question 4

A behavior analyst uses a procedure where a client practices desired behaviors repeatedly, followed by reinforcement. Which procedure does this describe?

A) Modeling

B) Task analysis

C) Behavioral rehearsal

D) Punishment

Show Answer & Explanation

Correct Answer: C

Explanation: Behavioral rehearsal involves practicing a behavior in a structured setting to improve performance and is often followed by reinforcement upon successful execution.

Question 5

A behavior analyst is using a DRO schedule to reduce hand flapping. The client receives a sticker for each 5-minute interval in which hand flapping does not occur. Which of the following best describes this procedure?

A) Negative reinforcement

B) Differential reinforcement of alternative behavior

C) Differential reinforcement of other behavior

D) Differential reinforcement of low rates

Show Answer & Explanation

Correct Answer: C

Explanation: DRO (Differential Reinforcement of Other behavior) reinforces the absence of a target behavior, in this case, the absence of hand flapping during specific time intervals.
