1. During natural environment training with bubbles, Maya eagerly requested 'bubbles' for the first ten minutes. Now she looks away when the RBT holds up the wand, drops the bubble container, and walks over to the window.
What do Maya's behaviors MOST likely indicate?
Answer: C
Looking away from the item, dropping the materials, and leaving the play area after a stretch of eager requesting are classic signs of satiation: the bubbles have temporarily lost their value as a reinforcer, so the RBT should follow Maya's lead to a different preferred activity. Deprivation is the opposite condition; a learner who has gone without an item shows more approach and requesting, not turning away. An extinction burst is a temporary increase in behavior when reinforcement is withheld, yet Maya's requests were being honored and her engagement decreased. Prompt dependence describes a learner who waits for prompts before responding, which does not explain abandoning the activity altogether.
2. During a receptive identification program, an RBT says 'Touch dog' with three picture cards on the table. The supervisor notices the RBT's hand hovering near the correct card, and the learner's accuracy drops whenever the RBT's hands rest in their lap.
What should the RBT do on future trials?
Answer: D
The hovering hand has become an unplanned gestural cue: the learner is responding to the RBT's hand rather than to the spoken instruction, which is why accuracy collapses when the hand is absent. Keeping hands stationary and away from the materials ensures the instruction itself controls responding. Pointing toward the correct card on each trial turns the accidental cue into a prompt that is not in the program and builds prompt dependence. Glancing at the correct card simply swaps one inadvertent cue for another, since many learners follow eye gaze. Sliding the correct card closer adds a position cue, so the learner can be correct without discriminating the pictures at all.
3. During a scheduled grocery store session, an RBT runs natural environment training with Priya, whose plan targets requesting preferred items, following one-step directions, and handing money to a cashier.
Which activity BEST fits natural environment training in this setting?
Answer: A
Natural environment training uses the opportunities that occur in a learner's real environments, and a grocery store gives Priya genuine chances to request the apples she wants and pay a real cashier, with getting the apples as the natural reinforcer. Practicing adaptive skills where they are needed supports generalization. Running fruit picture flashcards on a bench simply moves contrived discrete-trial teaching into the store; the location alone does not make teaching naturalistic. Saving the paying target for the clinic's mock store gives up a real opportunity the plan scheduled and delays generalization. Doing the shopping for Priya removes every learning opportunity and may reinforce passive waiting.
4. Liam has been taught to match pictures of farm animals to their printed names, but he has never been taught identity matching. His supervisor asks the RBT to probe whether Liam shows reflexivity.
Which probe trial should the RBT present?
Answer: B
Reflexivity means a learner matches a stimulus to an identical copy of itself without direct teaching, so the probe gives Liam a horse picture and an identical horse picture. Matching the horse picture to the printed word HORSE is the relation he was already taught, so it measures maintenance, not a derived relation. Matching the printed word HORSE to the horse picture reverses the trained relation, which is a symmetry probe. Saying horse aloud and asking him to touch the picture tests receptive identification, a different auditory-visual relation that does not involve identical stimuli. Only the identical-picture trial tells the supervisor whether reflexivity is present.
5. Ava has used a token board for completing classroom routines for six months. Her supervisor tells the RBT that the board will be gradually faded, with more routines required for each token and fewer exchanges each day.
What is the main purpose of this fading?
Answer: C
Token economies are a bridge, not a permanent arrangement. Fading thins the token schedule so that Ava's routines come under the control of naturally occurring contingencies, such as teacher praise, peer approval, and access to the next activity. Offering a larger backup reinforcer at each exchange moves in the opposite direction by making the artificial system richer. Switching to edible reinforcers replaces one contrived consequence with another and does not build independence from it. Expecting Ava to need no reinforcement at all misunderstands fading; behavior that contacts no reinforcement tends to extinguish, so the goal is to shift maintenance to the natural reinforcers already present in the classroom.
6. During natural environment training on counting and colors, Noah ignores the plain wooden blocks the RBT has set out. His recent preference assessment showed that he loves a particular cartoon dog and talks about it often.
What should the RBT do to BEST increase Noah's motivation?
Answer: D
Naturalistic teaching works best when it follows the learner's interests, so building counting and color targets around cartoon dog figures turns the preferred character into the teaching material and makes each response more motivating. Giving a cartoon dog sticker when the session ends delays the preferred item and leaves the unappealing blocks in place during the actual teaching. Moving the targets to the table for flashcard trials abandons the naturalistic format rather than fixing the motivation problem. Putting the cartoon dog toys out of sight treats a powerful motivator as a distraction and removes the very interest that could drive Noah's engagement during natural environment training.
7. Sofia is learning to say 'cat' only when shown a cat picture. When the RBT shows a dog picture, Sofia also says 'cat,' and the RBT praises her for trying so that she stays engaged.
What should the RBT change to teach this discrimination?
Answer: A
Discrimination training requires differential reinforcement: the response in the presence of the discriminative stimulus, the cat picture, is reinforced, and the same response in the presence of the S-delta, the dog picture, is not. Praising 'cat' for both pictures reinforces the word regardless of the stimulus, so the picture never gains control over the response. Praising 'cat' for the dog picture on every other trial puts the error on an intermittent schedule, which can make it even more persistent. Reprimanding Sofia adds a punishment procedure that is not in the plan and can make teaching aversive; the missing ingredient is simply withholding reinforcement when she responds to the S-delta.
8. An RBT is running a mystery motivator system with Ethan. He earns stars on a card for completed tasks, and the reward for a full card is sealed in an envelope on the RBT's clipboard.
When should the RBT reveal the reward in the envelope?
Answer: B
In a mystery motivator system, the backup reinforcer stays hidden until every required token is earned; the uncertainty about what is inside is part of what keeps the learner working. Revealing it before the first task turns the system into an ordinary token board and removes the mystery the plan relies on. Showing it halfway through the card delivers part of the payoff early and may weaken effort on the remaining tasks if Ethan does not care for the reward. Revealing it whenever Ethan asks makes the reveal contingent on asking rather than on completing tasks, which can reinforce repeated questioning instead of work.
9. Chloe's natural environment training goals include the prepositions in, on, and under. She is sitting on the playroom floor with a toy barn, plastic farm animals, and a small fence, happily moving the animals around.
How should the RBT BEST teach a preposition at this moment?
Answer: C
Prepositions are easy to teach naturally because the play materials themselves create the concept: asking Chloe to put the cow in the barn uses her current interest, requires a response, and lets her play continue as the natural consequence. Moving her to the table for picture flashcards replaces natural environment training with contrived discrete trials and pulls her away from a motivating activity. Waiting until free play is finished wastes the opportunity created by her engagement with the barn and animals. Describing where each animal is provides models, but Chloe is never asked to respond, so there is no opportunity to practice or reinforce the target.
10. During receptive labeling trials, an RBT has been saying 'Touch shoe' two or three times whenever Mia does not respond within a second or two. Mia now responds only after hearing the instruction repeated.
How should the RBT present the instruction from now on?
Answer: D
Repeating the instruction before the learner has a chance to respond teaches that the first instruction does not matter, so Mia has learned to wait for repetitions. The fix is to present the discriminative stimulus once, wait the response interval specified in the program, and then prompt according to the planned prompting procedure. Giving the instruction three times on every trial makes the problem the new standard rather than correcting it. Saying it louder each time still repeats the instruction and adds volume as one more cue Mia may come to depend on. Repeating until she responds and adding extra praise reinforces the very delay the RBT is trying to eliminate.
11. Marcus's plan states that two tokens are removed each time he throws materials. He has nine tokens when he throws a book during reading, and his teacher urges the RBT to take all of them to make the point stick.
How should the RBT respond to this throw?
Answer: A
Response cost must be implemented exactly as written, so the RBT removes the two tokens the plan specifies for throwing, continues the activity, and can share the teacher's concern with the supervisor. Removing all nine tokens because the teacher requests it changes the procedure without supervisor approval and can leave Marcus with nothing to lose, which often increases problem behavior. Removing four tokens because a book seems more serious substitutes the RBT's own judgment for the plan's fixed amount. Removing no tokens and giving a warning skips the planned consequence entirely, which makes the response cost inconsistent and can teach Marcus that throwing sometimes costs nothing.
12. Ben's incidental teaching target is requesting with a color and a noun. Toy cars sit on a high shelf; Ben reaches toward them and says 'car.' The RBT asks, 'Which car?' and Ben repeats 'car' while still reaching.
What should the RBT do next?
Answer: B
In incidental teaching, the learner initiates, the RBT asks for the target elaboration, and if the learner does not produce it independently, the RBT prompts it and then delivers the requested item after the prompted response. Modeling 'red car' and giving the car when Ben echoes it keeps the opportunity successful and reinforces the longer request. Handing over a car right away reinforces the one-word request the program is trying to expand. Putting the cars away wastes a moment of high motivation and may frustrate him. Asking 'Which car?' again and again without a prompt adds repeated demands, risks problem behavior, and gives Ben no model of the correct response.
13. When Grace's RBT holds up the sticker chart and says 'Clean up time,' putting toys in the bin earns Grace a sticker. At other times during the session, cleaning up does not produce a sticker.
What does the RBT's instruction with the chart signal to Grace?
Answer: C
The RBT's instruction with the chart is a discriminative stimulus: it signals that a specific behavior, cleaning up, will be reinforced with a sticker now. Grace's history of earning stickers only when the chart is shown is what gives it that function. Saying she has already earned a sticker describes a consequence that has been delivered, not an antecedent that signals availability. Saying stickers are suddenly more valuable describes a motivating operation, which changes how much a reinforcer is worth rather than whether it is available. Saying cleaning up will not produce a sticker describes an S-delta, the condition at other times when the chart is not shown.
14. Lucas, age 12, now reliably completes his after-school homework routine using a physical token board. His supervisor has approved fading the token system as he starts middle school.
Which change BEST represents fading the token system?
Answer: D
Fading can move a learner from physical tokens toward more natural, age-appropriate tools, and a checklist Lucas marks on a phone app is a more natural tool that looks like what other middle schoolers use. Adding more backup reinforcers enriches the artificial system instead of reducing reliance on it. Giving a token for every step thickens the schedule, which is the opposite of fading. Removing all tokens on the first day of school is abrupt withdrawal rather than gradual fading, and it risks a sharp drop in homework completion right when Lucas faces a new setting; fading works by changing the system in small, planned steps.
15. Zoe's plan includes mand, tact, and intraverbal targets, and she loves playing pretend picnic with a toy kitchen set. The RBT is about to begin natural environment training while Zoe sets out her picnic.
How should the RBT BEST address these targets?
Answer: A
A single play routine can naturally contain many verbal operants: Zoe can request the juice (mand), label the foods on her plate (tact), and complete a picnic song or answer questions about it (intraverbal), all within pretend picnic play. Embedding them keeps motivation high and mirrors how language is used in everyday life. Targeting only mands during play assumes naturalistic teaching is just for requests and misses easy tact and intraverbal opportunities. Teaching one operant per day is not required and slows progress. Pausing the picnic for massed blocks interrupts the activity that is supplying Zoe's motivation and turns the session back into contrived drill.
