When an RBT presents a handwriting worksheet, Jordan swipes the materials off the table. The RBT silently picks everything up, which takes about two minutes, and Jordan sits quietly during that time. The worksheet is then re-presented, and the swiping happens again. Which function is most likely maintaining the swiping?

Functions of behavior, antecedent interventions, differential reinforcement, extinction, punishment and crisis procedures.
What the RBT exam tests in Behavior Reduction
- Identify common functions of behavior (attention, escape, tangible, automatic)
- Use antecedent interventions: noncontingent reinforcement, high-probability request sequence, demand fading
- Use differential reinforcement: DRO, DRA, DRI, DRL, functional communication training
- Use extinction
- Use positive and negative punishment, e.g. time-out
- Describe side effects of extinction (burst, response variation, resurgence, emotional responding) and of punishment (emotional responses, escape and avoidance)
- Carry out crisis/emergency procedures
High-yield behavior reduction facts
- Antecedent interventions change what happens BEFORE the behavior.
- Noncontingent reinforcement (NCR): deliver the maintaining reinforcer on a time schedule regardless of behavior (e.g., attention every 2 min). This lowers the motivation to misbehave.
- High-probability request sequence: give 3 to 5 easy requests the learner reliably follows, then immediately give the low-probability request.
- Demand fading: temporarily reduce demands, then raise them gradually.
- Other antecedent strategies: choices, visual schedules, priming, transition warnings, environmental changes.
- During differential reinforcement, the problem behavior is usually placed on extinction at the same time.
| Procedure | Reinforce | Example |
|---|---|---|
| DRA | A specific alternative behavior | Praise hand-raising instead of calling out |
| DRI | A behavior physically incompatible with the problem behavior | Reinforce hands in lap instead of hand-flapping |
| DRO | ABSENCE of the problem behavior for a set interval | Token per 5 min with no spitting |
| DRL | A lower, acceptable rate of a behavior that is OK in moderation | Reinforce 3 or fewer questions per lesson |
| FCT | A communication response that gets the SAME reinforcer | 'Break please' instead of throwing materials (escape) |

Common behavior reduction traps
- DRO reinforces absence, DRA reinforces a specific replacement, and DRI requires physical incompatibility.
- DRL is for behaviors acceptable at low rates, never for dangerous behavior.
- Ignoring an escape-maintained behavior while removing the task is NOT extinction.
- Spontaneous recovery (the same behavior returns after a pause) vs resurgence (an earlier behavior returns when the replacement stops paying off).
- NCR is time-based and not contingent on behavior; DRO is contingent on the absence of behavior.
- An RBT never adds, changes or drops a reduction procedure on their own.
- Time-out for escape-maintained behavior can increase the behavior.
Free RBT behavior reduction practice questions
Question 1
A functional assessment shows that Ava's tantrums during math worksheets are maintained by escape from the work. The BCBA is writing a functional communication training (FCT) plan. Which replacement response is most appropriate to teach Ava?
- ASaying "play with me" to get an adult to interact with her
- BHanding the adult a "break" card to get a short break from the worksheet
- CAsking for a snack when she feels frustrated with the worksheet
- DSitting quietly for 5 minutes to earn a sticker on her chart
Show answer and explanation
Answer: B. FCT teaches a communication response that produces the same reinforcer as the problem behavior, which here is a break from the task.
Why not A: This mand produces attention, which does not match the escape function. The tantrums would still be the way she gets out of work.
Why not C: This mand produces a tangible item, not relief from the task. It does not give her an appropriate way to get the same outcome as the tantrum.
Why not D: This is closer to DRO than FCT. It does not teach a communication response that produces the maintaining reinforcer.
Remember: In FCT, the communication response must produce the same reinforcer that maintains the problem behavior.
Question 2
Leo grabs the RBT's arm to get attention. His plan calls for DRA: withhold attention for grabbing and reinforce tapping the RBT's shoulder while saying "excuse me." Leo grabs the RBT's arm, and the RBT does not respond. One minute later, Leo taps her shoulder and says "excuse me." What should the RBT do?
- ARemind Leo not to grab before turning to give him attention
- BTurn and give Leo attention right away for the tap and "excuse me"
- CWait several minutes before responding so the grabbing is not reinforced
- DIgnore the tap, because grabbing happened only a minute earlier
Show answer and explanation
Answer: B. DRA requires reinforcing the alternative behavior promptly, so the replacement becomes more effective than grabbing at producing attention.
Why not A: The reminder gives attention linked to the grabbing. It also delays and dilutes reinforcement for the correct response.
Why not C: Delaying reinforcement weakens the link to the replacement behavior. The grabbing was already put on extinction when it happened.
Why not D: DRA has no rule that cancels reinforcement after a recent problem behavior. Ignoring the replacement response would put it on extinction and weaken it.
Remember: In DRA, reinforce the replacement behavior immediately every time while withholding reinforcement for the problem behavior.
Question 3
Jordan screams during math worksheets, and his functional assessment shows the screaming is maintained by escape from tasks. A new staff member suggests sending Jordan away from the work table for time-out each time he screams. What is the most likely result?
- AScreaming undergoes extinction, because no attention is given during time-out.
- BScreaming decreases, because Jordan loses access to the worksheet.
- CScreaming decreases, because time-out is a punishment procedure by definition.
- DScreaming increases, because time-out removes the task and acts as negative reinforcement.
Show answer and explanation
Answer: D. For escape-maintained behavior, leaving the table removes the demand, so time-out would likely strengthen screaming.
Why not A: Withholding attention would only be extinction if the behavior were maintained by attention. Jordan's screaming is maintained by escape.
Why not B: For a learner trying to escape, losing access to the worksheet is what he wants, not a loss of reinforcement.
Why not C: A procedure counts as punishment only if the behavior decreases. A procedure's name does not guarantee its effect.
Remember: Time-out works only when the time-in setting is reinforcing, so it can reinforce escape-maintained behavior.
Question 4
During a clinic session, a client slips, strikes her head on a table, and becomes unresponsive. What should the RBT do first?
- AComplete an incident report while the details are still fresh.
- BGently prompt the client to sit up and resume the session.
- CActivate the emergency protocol and get emergency medical help.
- DCall the supervisor and wait for instructions before taking any action.
Show answer and explanation
Answer: C. In a medical emergency, the first priority is the client's safety, which means following the emergency protocol and contacting emergency services. Notifying the supervisor and documenting come afterward.
Why not A: Documentation is required, but it comes after the client's immediate safety and medical needs are addressed.
Why not B: An unresponsive client after a head injury needs emergency medical attention, and moving or prompting her could cause further harm.
Why not D: A medical emergency requires immediate action under the emergency protocol, and waiting for supervisor guidance delays care.
Remember: In a medical emergency, get help and follow the emergency protocol first, then notify the supervisor and document.
Question 5
A client's plan uses a 5-minute resetting DRO for spitting. Three minutes into the interval, the client spits. What should the RBT do?
- ADeliver the reinforcer at the 5-minute mark because only one spit occurred
- BWithhold the reinforcer and restart a new 5-minute interval from that point
- CShorten the DRO interval to 2 minutes so the client can earn reinforcement
- DGive a verbal reprimand and let the original interval continue running
Show answer and explanation
Answer: B. In a resetting DRO, the behavior cancels the current interval and a fresh full interval begins immediately.
Why not A: Any occurrence of the target behavior means the interval was not met. Delivering the reinforcer would reinforce an interval that contained spitting.
Why not C: Changing interval length is a programming decision for the supervising BCBA. The RBT should implement the plan as written.
Why not D: A reprimand is not part of the DRO procedure, and in a resetting DRO the timer does not keep running after the behavior occurs.
Remember: In a resetting DRO, any instance of the target behavior restarts the full interval with no reinforcer delivered.
