RBT Behavior Assessment Questions and Answers

A is correct. MSWO presents an array, removes the selected item, and re-presents the smaller array. The order of selection produces a ranked hierarchy of preference, which is why MSWO is so widely used before sessions.

B is wrong because paired-stimulus presents exactly two items at a time and works through every possible pair. C is wrong because with replacement the chosen item is returned to the array, so the array size never shrinks. D is wrong because free-operant involves no presentation at all — the RBT simply watches what the client engages with when everything is freely available.

C is correct. Free-operant observation requires no items to be taken away — the client has open access and the RBT records what he engages with and for how long. That avoids evoking the very behavior the question describes.

A is wrong because MSWO removes the selected item after every trial, which is exactly the situation that upsets this client. B is wrong because paired-stimulus also involves repeatedly removing items between trials. D is wrong for the same reason as A, and a larger array means more removals, not fewer.

B is correct. Satiation is an abolishing operation: it momentarily decreases the value of food as a reinforcer and therefore decreases behavior that has produced food in the past. The reinforcer has not stopped working permanently — its value has temporarily dropped.

A is wrong because an establishing operation increases reinforcer value, which is what deprivation does. C is wrong because extinction means the reinforcer is being withheld after responding; here it is still being delivered, it simply no longer motivates. D is wrong because stimulus generalization concerns responding to similar stimuli, which is unrelated to motivation.

B is correct. ABC stands for antecedent, behavior, consequence. Recording all three lets the supervisor look for patterns that suggest what is maintaining the behavior.

A is wrong because those are client characteristics, not a description of an event sequence. C is wrong because it substitutes unrelated terms for B and C; baseline and mastery criteria belong to program design, not descriptive assessment. D is wrong because a time-blocked count is a measurement procedure that captures how often the behavior happened but nothing about what surrounded it.

D is correct. The behavior reliably follows a demand and reliably produces removal of that demand. Termination of the task is negative reinforcement, which makes escape the most likely function.

A is wrong because although the RBT interacts with Talia, the consistent consequence is removal of work rather than delivery of social attention. C is wrong because no preferred item is delivered — a break is not a tangible. B is wrong because automatic reinforcement is produced by the behavior itself, independent of anyone's response; here the behavior clearly depends on what the RBT does next.

A is correct. Preferences shift, which is exactly why preference assessments are repeated. The RBT reports what she found and follows her supervisor's direction on how to use it.

B is wrong because older data do not describe what the client values today, and reinforcer effectiveness is a present-tense question. C is wrong because inventing a merged list is a clinical decision outside the RBT's role. D is wrong because re-running an assessment until it produces a desired answer is manipulating the result rather than measuring preference.

B is correct. The attention condition tests whether problem behavior is maintained by social attention. The RBT appears busy, withholds attention, and delivers a brief statement of concern only when the target behavior occurs.

A is wrong because that is the demand (escape) condition. C is wrong because free access with no demands is the control or play condition, which serves as the comparison. D is wrong because being alone with no materials is the alone condition, used to test automatic reinforcement.

A is correct. Interpreting assessment results and speaking to diagnosis or severity is outside the RBT scope of practice. Redirecting the question to the supervisor, warmly and without deflecting the parent, is the correct action.

B is wrong because an impression about diagnostic severity is a clinical interpretation an RBT is not qualified or authorised to give. C is wrong because it is false and needlessly cold — RBTs communicate with families constantly, just within their scope. D is wrong because handing over raw scores pushes the interpretation onto the parent and can cause real harm.

C is correct. Each item must appear opposite every other item exactly once. With four items that is 4 × 3 ÷ 2 = 6 unique pairs.

A is wrong because 4 is the number of items, not the number of pairings. B is wrong because 8 does not correspond to any standard pairing calculation for four items. D is wrong because 12 counts each pair twice — that is 4 × 3 without dividing by two, which would present AB and BA as separate trials.

A is correct. Going without juice for the length of the session is deprivation, an establishing operation that momentarily raises the value of juice as a reinforcer and increases behavior that has produced it.

B is wrong because juice is an unconditioned reinforcer, and in any case conditioning would not explain a within-session change in effectiveness. C is wrong because generalization concerns responding spreading to new stimuli or settings, not changes in motivation. D is wrong because schedule thinning describes requiring more responses per reinforcer, which is a procedural change nobody made here.

C is correct. Descriptive assessment observes what naturally co-occurs with the behavior. Because nothing is manipulated, it can suggest a likely function but cannot establish that a consequence is actually maintaining the behavior.

A is wrong because the natural environment is precisely where ABC data are collected — that is its advantage. B is wrong because descriptive assessment is used across behaviors of every severity. D is wrong because RBTs routinely collect ABC data under supervision; it is the interpretation that belongs to the BCBA.

B is correct. Assisting means administering the portions the supervisor assigns and recording responses faithfully. The RBT contributes accurate data; the supervisor does everything that requires clinical judgement.

A is wrong because instrument selection is a clinical decision made by the BCBA. C is wrong because interpreting results and authoring the report are supervisor responsibilities. D is wrong because goal selection follows from interpretation of the assessment, which is again outside the RBT role.

C is correct. A preference assessment identifies likely reinforcers. Something is only a reinforcer if delivering it contingently actually increases the behavior it follows — the data determine that, not the assessment.

A is wrong because "definitely" overstates it; motivating operations and satiation can undo a preference within minutes. B is wrong because the assessment says nothing about whether the item's value was learned or unlearned. D is wrong because preferences shift, which is why assessments are repeated frequently, often before each session.

D is correct. Behavior that persists when no one is available to deliver a consequence is most likely producing its own reinforcement — the sensory outcome of the behavior itself maintains it.

A is wrong because nobody is present to provide attention, so attention cannot be the maintaining consequence. B is wrong because no demands are being placed, so there is nothing to escape. C is wrong because no tangible items are available to be accessed. The defining feature of the scenario is precisely the absence of any social consequence.

C is correct. The antecedent column records what actually happened in the environment immediately before the behavior — an instruction delivered, an item removed, a peer approaching. "Bad mood" is an interpretation that another observer could not verify.

A is wrong because the entry is vague rather than overly detailed. B is wrong because the antecedent and consequence columns are distinct by design. D is wrong because moving an unobservable inference to a different column does not make it observable; the fix is to describe what was seen.

D is correct. In a free-operant assessment the client has open access to an array and the RBT records duration of engagement with each item. Longer engagement suggests higher preference.

A is wrong because first selection from a pair describes the paired-stimulus format. C is wrong because trials-to-criterion is a teaching measure, not a preference measure. B is wrong because free-operant does not involve offering items one at a time, so refusal is not the unit being recorded.

B is correct. Assessments are administered as designed so results are comparable and interpretable. The RBT's observation is genuinely useful — she reports it, and the supervisor decides what it means.

A is wrong because skipping items without authorisation creates a gap the supervisor cannot interpret. C is wrong because prompting during an assessment measures prompted performance instead of independent skill, which invalidates the item. D is wrong because substituting items changes what the assessment measures and is a clinical decision outside the RBT role.

C is correct. Skipping breakfast is food deprivation — an establishing operation that raises the momentary value of crackers and increases behavior that produces them. That is the definition of an MO in action.

A is wrong because differential responding to red versus blue is stimulus control from discrimination training. B is wrong because responding dropping when reinforcement stops is extinction, a consequence-based effect. D is wrong because performing across a new therapist is generalization. Only B involves a change in how valuable a consequence is.

B is correct. Descriptive assessment depends on catching the behavior as it happens. When the behavior is rare, the RBT may observe for weeks before enough instances accumulate to suggest a pattern.

A is wrong because ABC data are routinely collected on aggression. C is wrong because there is no such fixed threshold. D is wrong because the choice of assessment method is the supervisor's decision and depends on many factors; a functional analysis of dangerous behavior carries its own risks and requirements.

B is correct. MSWO requires one selection per trial to produce a valid ranking. Blocking the extra reach and re-presenting keeps the procedure intact and yields a scorable trial.

A is wrong because two simultaneous selections break the ranking logic the procedure depends on. C is wrong because recording a choice the client did not make substitutes the RBT's guess for data. D is wrong because a single ambiguous trial is a routine, easily corrected event, not a reason to abandon the assessment.

A is correct. The behavior occurs specifically when a preferred item is removed and reliably results in the item being returned. Access to the tangible is the maintaining consequence.

B is wrong because the screaming does not occur during work demands, which is the opposite of what an escape function would predict. C is wrong because although a peer is involved, the consistent outcome is return of the tablet rather than social attention. D is wrong because the behavior depends entirely on what the peer does next, so it is socially mediated rather than automatically reinforced.

C is correct. The RBT's contribution to assessment is accurate, faithful data collection under the supervisor's direction. That contribution is essential, but it stops short of interpretation.

A is wrong because designing and interpreting assessments requires the analytic training a BCBA has. B is wrong because determining function is exactly the interpretive step reserved for the supervisor. D is wrong because deciding the assessment is complete is a clinical judgement based on interpreting the data so far.

C is correct. Reinforcer value is momentary. A client who is satiated on an item, or newly deprived of another, will respond very differently — so a fresh assessment keeps teaching sessions effective.

A is wrong because although choice is a genuine benefit, it is not the reason the assessment's timing matters. B is wrong because the BACB sets no such rule; assessment frequency is a clinical decision. D is wrong because running assessments more often increases the data the RBT collects, not decreases it.

A is correct. Functional analysis protocols include predefined safety and termination criteria precisely because behavior can escalate. Following them and alerting the BCBA is both the safe and the procedurally correct action.

B is wrong because client safety always outranks data integrity; no analysis is worth an injury. C is wrong because changing conditions on her own initiative is a clinical decision outside her role, and it contaminates the analysis. D is wrong because it abandons the protocol rather than following the escalation procedure the protocol already specifies.
