BCABA Behavior-Change Procedures Sample Questions with Answers

Sample Question 1 — Behavior-Change Procedures

Noncontingent reinforcement (NCR) involves:

  1. A. Delivering a reinforcer only after the client performs a specified target behavior
  2. B. Delivering a reinforcer on a time-based schedule, independent of the client's behavior (Correct answer)
  3. C. Withholding reinforcement for the problem behavior while reinforcing an alternative
  4. D. Removing a reinforcer each time the client engages in the target problem behavior

Correct answer: B

Explanation: B is correct because NCR provides reinforcers on a fixed-time or variable-time schedule regardless of what the client is doing, which can reduce motivation for problem behavior. A describes contingent reinforcement. C describes differential reinforcement of alternative behavior with extinction. D describes negative punishment, such as response cost.

Sample Question 2 — Behavior-Change Procedures

A client's calling out is maintained by adult attention. The supervisor plans to provide attention every 2 minutes, regardless of the client's behavior. What is the main purpose of this procedure?

  1. A. To reduce the motivating operation for attention, making calling out less likely (Correct answer)
  2. B. To place calling out on extinction by never providing attention again
  3. C. To teach the client to request attention in an appropriate way
  4. D. To punish calling out by removing attention whenever the behavior occurs

Correct answer: A

Explanation: A is correct because frequent noncontingent attention decreases the value of attention as a reinforcer, which reduces the motivation to call out. B is wrong because attention is still being delivered frequently. C is wrong because no alternative response is being taught or reinforced. D is wrong because attention is delivered on a time-based schedule rather than removed.

Sample Question 3 — Behavior-Change Procedures

A client engages in problem behavior to escape difficult tasks. The supervisor plans to teach the client to request a break, honor each request at first, and then gradually require more work before breaks are given. Which BEST describes this procedure?

  1. A. Negative reinforcement of an appropriate request, combined with gradual demand fading (Correct answer)
  2. B. Noncontingent reinforcement, because breaks are provided on a time-based schedule
  3. C. Positive reinforcement of problem behavior, because the client receives breaks during sessions
  4. D. Negative punishment of problem behavior, because work is added when the client requests a break

Correct answer: A

Explanation: A is correct because the break (removal of the task) is delivered contingent on an appropriate request, strengthening that request, and work requirements are then increased gradually. B is wrong because breaks depend on the client's request, not the passage of time. C is wrong because breaks are delivered for the request rather than for problem behavior. D is wrong because requesting a break produces removal of the task, which increases requesting.

Sample Question 4 — Behavior-Change Procedures

A client does not respond to praise. Which procedure is MOST likely to establish praise as a conditioned reinforcer?

  1. A. Repeatedly deliver praise just before delivering an established reinforcer (Correct answer)
  2. B. Deliver the established reinforcer first, then deliver praise several minutes later
  3. C. Deliver praise at the end of the day, separate from any other reinforcer
  4. D. Replace all established reinforcers with praise so the client learns to value it

Correct answer: A

Explanation: A is correct because pairing praise with an effective reinforcer, with praise occurring immediately before it, can give praise its own reinforcing value. B reverses the order and delays the pairing, which reduces conditioning. C does not pair praise with established reinforcers in a way likely to condition it. D removes effective reinforcers before praise has acquired any reinforcing value.

Sample Question 5 — Behavior-Change Procedures

A BCaBA introduces a token system for a client who has never used tokens. What is the BEST way to begin?

  1. A. Allow the client to exchange tokens only at the end of each week
  2. B. Deliver tokens without any backup reinforcers until the client shows interest in them
  3. C. Require 10 tokens before any exchange, so the client learns to work for longer periods
  4. D. Allow exchange after one token at first, then gradually increase the number required (Correct answer)

Correct answer: D

Explanation: D is correct because starting with immediate exchange quickly pairs tokens with backup reinforcers, and gradually increasing the requirement helps maintain responding. A creates long delays that are unlikely to establish tokens as effective reinforcers. B fails to give tokens value, because they are never paired with backup reinforcers. C delays access to backup reinforcers before tokens have acquired value, which may weaken responding.

Sample Question 6 — Behavior-Change Procedures

Which strategy uses a motivating operation to increase a client's mands for juice during teaching sessions?

  1. A. Providing unlimited juice immediately before sessions so that the client stays calm
  2. B. Placing juice out of sight during all sessions so the client is not distracted
  3. C. Labeling juice repeatedly during sessions without giving the client any juice
  4. D. Limiting access to juice before sessions so that it is more valuable during mand training (Correct answer)

Correct answer: D

Explanation: D is correct because restricting access (deprivation) increases the value of juice as a reinforcer and makes mands for juice more likely. A produces satiation, which decreases the value of juice and mands for it. B may reduce opportunities to mand but does not increase the item's value. C may teach tacts or listener skills but does not contrive motivation to request juice.

Sample Question 7 — Behavior-Change Procedures

A client engages in escape-maintained problem behavior during math. Which antecedent strategy is MOST likely to reduce the motivating operation for escape?

  1. A. Increasing the number of difficult problems presented in each session
  2. B. Delivering a reprimand each time the client stops working on math
  3. C. Interspersing easier problems and offering choices about the order of tasks (Correct answer)
  4. D. Providing a break whenever problem behavior occurs during math

Correct answer: C

Explanation: C is correct because making tasks less aversive, such as by interspersing easier problems and offering choices, reduces the value of escape. A makes the task more aversive and may increase motivation to escape. B adds a consequence rather than changing the antecedent motivating operation. D reinforces problem behavior with escape rather than reducing motivation.

Sample Question 8 — Behavior-Change Procedures

During mand training for "ball," a client says "ball" only when the therapist holds up the ball and asks, "What do you want?" The client never says "ball" when reaching for the ball during play. Which BEST describes the problem and a solution?

  1. A. The response is an echoic, so the therapist should model the word "ball" more often
  2. B. The response is a mand under appropriate control, so continue teaching exactly as before
  3. C. It is controlled by prompts, so fade them and contrive times the ball is wanted (Correct answer)
  4. D. The client lacks motivation for the ball, so it should be removed from teaching entirely

Correct answer: C

Explanation: C is correct because a mand should be controlled by the motivating operation; fading the verbal and visual prompts while arranging situations in which the client wants the ball helps transfer control. A misidentifies the operant, because the therapist is not saying "ball" for the client to repeat. B overlooks that the response occurs only with the therapist's prompts, not when the client wants the ball. D is not supported, because the client reaches for the ball during play.

Sample Question 9 — Behavior-Change Procedures

Which is an example of a conditional discrimination?

  1. A. Raising a hand whenever a bell rings at the start of each class period
  2. B. Clapping whenever music begins to play in the classroom during circle time
  3. C. Touching a red card whenever it is placed on the table, regardless of what anyone says
  4. D. Selecting the dog or cat picture depending on which word the therapist says (Correct answer)

Correct answer: D

Explanation: D is correct because in a conditional discrimination, the correct response to comparison stimuli depends on the sample stimulus, here the spoken word. A is a simple discrimination, because the response is controlled by one stimulus. B is a simple discrimination, because clapping is controlled by one stimulus. C is a simple discrimination, because the response depends on a single stimulus.

Sample Question 10 — Behavior-Change Procedures

When teaching a client to discriminate between "cup" and "spoon" during receptive identification trials, which arrangement BEST prevents faulty stimulus control?

  1. A. Present "cup" for all trials in the first half of the session and "spoon" for the second half
  2. B. Hold the correct item slightly closer to the client on every trial
  3. C. Randomize the positions of the items and the order of the instructions across trials (Correct answer)
  4. D. Always place the correct item on the same side so the client learns where to look

Correct answer: C

Explanation: C is correct because varying item positions and instruction order ensures that correct responding depends on the spoken word rather than irrelevant cues. A allows the client to respond correctly by repeating the previous response. B adds an irrelevant cue that could control responding. D would bring responding under control of position rather than the spoken word.
