6 Free BCBA Behavior Reduction Procedures Practice Questions with Answers

Sample Question 1 — Behavior Reduction Procedures

A 7-year-old client with autism frequently engages in hand-flapping during transitions. Functional assessment suggests this is maintained by automatic reinforcement. Which intervention is MOST appropriate?

  1. A. Extinction of hand-flapping combined with positive reinforcement for appropriate transition behaviors.
  2. B. Response blocking of hand-flapping with no replacement behavior taught.
  3. C. Ignoring hand-flapping and only providing attention when the child is engaged in other activities.
  4. D. Providing a competing sensory activity to reduce the need for self-stimulatory behavior. (Correct answer)

Correct answer: D

Explanation: When a behavior is maintained by automatic reinforcement, the most appropriate intervention targets the sensory consequences produced by the behavior itself. Providing a competing sensory activity (also called a competing stimulus or matched stimulation) gives the learner access to similar or functionally equivalent sensory input, thereby reducing the motivation to engage in hand-flapping during transitions. This approach is evidence-based and commonly recommended for automatically reinforced stereotypy. Why the other options are less appropriate: A: Extinction for automatically reinforced behavior is often impractical or ineffective because the reinforcement is internally produced and cannot be easily withheld. While reinforcing appropriate transitions is good practice, extinction alone does not address the sensory function. B: Response blocking without teaching a replacement behavior is overly restrictive, may increase problem behavior, and does not address the underlying sensory need. C: Ignoring the behavior targets socially mediated attention functions, which is inconsistent with the functional assessment indicating automatic reinforcement.

Sample Question 2 — Behavior Reduction Procedures

A teenager with ADHD frequently leaves assigned tasks incomplete. Data shows that this is due to difficulty with task initiation. What strategy is LEAST likely to be effective?

  1. A. Task analysis and chaining to break down large tasks into smaller, manageable steps.
  2. B. Implementing a self-monitoring system where the teenager tracks their task completion.
  3. C. Applying immediate punishment (e.g., removal of privileges) each time an assignment is left incomplete. (Correct answer)
  4. D. Using positive reinforcement for completing smaller segments of a task.

Correct answer: C

Explanation: Option C is least likely to be effective because punishment, especially immediate and aversive punishment, is generally less effective than positive reinforcement and can lead to negative side effects such as anxiety and avoidance. Options A, B, and D focus on increasing task completion through positive reinforcement, breaking down tasks, and self-management strategies.

Sample Question 3 — Behavior Reduction Procedures

A client with intellectual disability engages in aggression when denied access to preferred items. After conducting a functional assessment, you determine the function is to gain access to the item. What intervention should you prioritize?

  1. A. Ignoring the aggression and focusing on reinforcing alternative communication strategies.
  2. B. Immediately removing the client from the environment when aggression occurs.
  3. C. Teaching the client to request the items using functional communication training (FCT). (Correct answer)
  4. D. Using punishment such as time-out contingent on aggression.

Correct answer: C

Explanation: FCT teaches the client a more appropriate way to obtain the desired item, directly addressing the function of the behavior. Ignoring (A) may not be effective if the behavior is strongly reinforced. Removal (B) does not teach an alternative behavior. Punishment (D) is less effective and may cause negative side effects.

Sample Question 4 — Behavior Reduction Procedures

A preschooler exhibits frequent tantrums in the classroom. Data shows tantrums occur most frequently when transitions are required. What is the BEST first step in addressing this behavior?

  1. A. Immediately implement a token economy to reinforce appropriate behavior during transitions.
  2. B. Conduct a functional behavior assessment (FBA) to determine the function of the tantrums. (Correct answer)
  3. C. Inform the parents that the child needs more discipline at home.
  4. D. Introduce a time-out procedure whenever a tantrum occurs.

Correct answer: B

Explanation: An FBA is crucial before selecting an intervention. It helps determine the function of the tantrums to ensure the intervention directly addresses the problem. Options A, C, and D jump to interventions without understanding the function of the behavior.

Sample Question 5 — Behavior Reduction Procedures

You're working with a client who exhibits self-injurious behavior (SIB). You've implemented a behavior intervention plan that includes extinction of SIB and differential reinforcement of alternative behaviors (DRA). The client's SIB is increasing. What is the MOST likely explanation?

  1. A. The DRA is not effective.
  2. B. Extinction bursts are occurring. (Correct answer)
  3. C. The reinforcement for SIB is too strong.
  4. D. The client is manipulative.

Correct answer: B

Explanation: An extinction burst is a temporary increase in the problem behavior when extinction is implemented. Options A, C, and D are possible, but the temporary increase in the problem behavior during extinction is a common and expected occurrence.

Sample Question 6 — Behavior Reduction Procedures

A client engages in elopement (running away) from the classroom. A functional assessment reveals the behavior is maintained by access to preferred activities in other areas of the building. Which strategy is MOST likely to be effective?

  1. A. Using punishment for elopement.
  2. B. Ignoring the elopement.
  3. C. Implementing a premack principle, where accessing preferred activities is contingent upon staying in the classroom. (Correct answer)
  4. D. Increasing demands within the classroom to reduce boredom.

Correct answer: C

Explanation: The Premack principle (first-then) directly addresses the function of the behavior by making access to preferred activities contingent on appropriate behavior. Punishment (A) might suppress the behavior temporarily but doesn't teach an alternative. Ignoring (B) is unlikely to be effective. Increasing demands (D) could worsen the problem.
