RBT Practice Questions

When an error occurs during an errorless learning procedure, the RBT must immediately interrupt or clear the materials and re-present the trial with a controlling prompt to ensure the learner emits the correct response. Delivering verbal praise and removing all of the materials from the table is incorrect because praise should only follow correct responses, not errors. Ending the session and reporting the data to the supervisor immediately is unnecessary and disrupts instructional flow, as single errors are handled directly through protocol. Recording the trial response as correct on the acquisition datasheet is improper because errors must be accurately documented as incorrect or prompted per the BCBA's instructions.

In demand fading, task demands are initially reduced to a level where problem behavior does not occur and are systematically faded back in. When the client completes the designated criterion, the RBT must immediately deliver reinforcement without presenting unexpected additional demands. Asking the client to trace an extra letter violates the established contingency and may evoke problem behavior by breaking behavioral trust. Withholding reinforcement until the entire worksheet is completed undermines the demand fading protocol completely. Requiring the client to clean up their pencil introduces an extra, unprogrammed demand prior to reinforcement, which can trigger escape-maintained property destruction.

Percentage change is calculated by finding the absolute difference between the baseline and intervention values, dividing that difference by the baseline value, and multiplying by 100. Here, the difference between 40 and 10 is 30. Dividing 30 by the baseline value of 40 yields 0.75, which equals a 75% decrease. The value 25% represents the intervention rate as a proportion of baseline (10 divided by 40), rather than the percentage decrease. The value 30 represents the raw numerical reduction in screams, not a percentage. The value 300% results from erroneously dividing the difference of 30 by the intervention value of 10 instead of the baseline value.

Maintaining client dignity requires behavior technicians to treat clients with respect, preserve privacy, and avoid unnecessary public embarrassment. When managing challenging behaviors in community settings, the RBT should implement the prescribed behavior plan calmly, quietly, and discreetly to minimize attention from onlookers. Announcing the client's developmental diagnosis to bystanders violates confidentiality and severely compromises client dignity. Calling out loud verbal reprimands is counterproductive, potentially stigmatizing, and draws excessive social focus to the client. Threatening to revoke future community outings constitutes an unauthorized, non-dignified disciplinary threat rather than adhering to objective, proactive behavioral interventions approved by the supervisor.

Documenting the odor and client distress in the objective session notes is correct because RBTs must report environmental variables that could alter client performance or behavior. Strong paint fumes are an aversive environmental event that explains task refusal and distress. Canceling all scheduled sessions for the remainder of the week immediately is incorrect because scheduling cancellations must be handled by administrative staff or the supervising behavior analyst. Implementing an extinction procedure to address the client's crying behavior is incorrect because the distress is a reaction to an aversive environmental stimulus, not a target behavior requiring an unauthorized behavior plan modification. Changing the client's skill-acquisition targets to independent indoor play is incorrect because RBTs cannot alter instructional targets without supervisor direction.

Presenting tactile, auditory, or olfactory stimuli for selection is correct because preference assessments must accommodate sensory deficits by using non-visual modalities such as textured objects, sounds, or scents that the learner can experience. Using high-contrast line drawings placed very close to the eyes is incorrect because visual stimuli remain inaccessible or frustrating for a client with severe visual impairment. Conducting a standard pictorial multiple-stimulus assessment array is incorrect because pictorially mediated choices rely entirely on visual discrimination skills that the learner lacks. Eliminating preference assessments and choosing items based on age is incorrect because assuming preferences based on chronological age denies individualized reinforcement and violates person-centered behavioral assessment standards.

Varying the instructor's physical position promotes stimulus generalization by preventing the client from responding only when directly facing the technician. Learners can become overly dependent on specific environmental cues, such as the instructor sitting squarely in front of them, if positioning is never altered. Evaluating whether the learner exhibits unexpected sensory deficits is outside the scope of an RBT and describes a diagnostic or medical evaluation. Increasing the overall physical effort required to emit the response is not a clinical objective and may decrease motivation. Eliminating the need for delivering reinforcement during later sessions relates to schedule thinning rather than instructor positioning.

In differential reinforcement during skill acquisition, independent responses receive greater reinforcer magnitude than prompted responses to motivate the learner to respond without assistance. Prompted responses should still receive lower-magnitude reinforcement rather than complete extinction so the learner remains engaged and successful. Differential reinforcement varies the quality or magnitude of the reinforcer rather than switching between continuous and intermittent schedules within the same teaching trial. Experiencing a prompted trial does not mean the target should be discontinued, but rather that the technician is providing necessary instructional support.

Calculating a percentage requires dividing the number of observed responses by a fixed, known total number of opportunities and multiplying by 100. In an unstructured setting without discrete trials, there is no predetermined ceiling or fixed maximum number of opportunities, making percentage mathematically invalid and misleading; rate or frequency should be used instead. Social greetings do not need to be measured using latency, as latency measures the time between an antecedent stimulus and the initiation of a behavior. Percentage data can be recorded regardless of whether a session is under or over one hour. Unstructured sessions do not mandate whole-interval recording, which often underestimates behavior.

According to BACB requirements, an RBT cannot provide official supervision to another RBT. Supervision must be provided by a qualified supervisor, such as a BCBA, BCaBA, or an approved licensed professional who has completed the required supervisory training. Years of clinical experience do not qualify a technician to act as a formal BACB supervisor. Periodic review of notes by a clinical director cannot substitute for direct oversight by a credentialed supervisor. Even if an individual holds a master's degree, they cannot serve as a BACB supervisor while credentialed solely as an RBT; they must hold appropriate supervisory status recognized by the BACB.

Informing the supervisor that personal stress is impairing service delivery is the best course of action because the BACB Ethics Code requires technicians to seek clinical direction when personal issues adversely impact their clinical performance. Continuing to work while attempting to handle the situation privately at home is incorrect because unaddressed burnout directly compromises client welfare and data integrity. Asking the client's parents to cancel afternoon sessions until stress subsides is incorrect because scheduling adjustments must be coordinated through agency leadership, not negotiated informally with clients. Reassigning the client's therapy cases directly to a coworker without notice is incorrect because technicians lack the administrative and clinical authority to transfer or delegate caseload assignments independently.

Recording that the client pushed the wooden chair onto the floor provides a directly observable, objective, and measurable description of the physical actions without interpreting internal mental states. Stating that the client felt frustrated is incorrect because frustration is an internal emotional state that cannot be directly observed or measured by an technician. Describing the client as becoming angry and noncompliant is incorrect because anger is an inference rather than an observable behavior. Noting that the client showed defiance is incorrect because defiance is a subjective judgment that fails to describe the specific physical topography of what the client actually did.

An auditory prompt involves using a sound or vocal cue, such as a recorded voice providing step-by-step spoken directions, to guide the learner through the steps of a behavior chain. A gestural prompt involves non-vocal physical movements, such as pointing, nodding, or motioning toward an item to signal the correct response. A physical prompt involves manually guiding the learner's body through the required motor action. A visual prompt involves graphic or written materials, such as illustrations, checklists, or written text, rather than spoken recordings. Here, the learner relies on recorded sound to complete each task step.

Mechanical restraint involves using unauthorized devices or physical equipment to restrict a client's freedom of movement. Physical restraint involves a technician using their own body to restrict a client's movement without equipment. Protective blocking involves deflecting an incoming strike or using a pad as a shield without holding the client. Response blocking involves physically preventing the completion of an action, such as blocking hand-to-mouth contact, rather than securing a client to furniture with equipment. Using unauthorized mechanical devices violates professional and ethical safety guidelines.

On a cumulative record, the vertical axis (Y-axis) displays the running total of responses accumulated across successive sessions or observation periods. Each new response adds to the previous total, meaning the line can only rise or remain flat; it can never decrease. The percentage of correct trials completed in a session is plotted on a standard line graph, not a cumulative record. The average duration of completed tasks measures time rather than cumulative count, which requires a standard duration graph. The total number of errors across conditions would also be graphed separately on a standard line graph rather than combined cumulatively with correct responses.

Behavior technicians must practice within their professional boundaries and refer administrative, financial, and billing questions to appropriate leadership. Directing the parent to the billing department or supervising BCBA ensures the family receives accurate, authorized information while keeping the technician within their defined scope of practice. Reviewing the family's insurance policy documents is inappropriate because RBTs are not trained or authorized to evaluate third-party contracts or adjudicate claims. Promising that future sessions will use different billing codes is unethical and constitutes fraudulent billing practice. Discussing hourly reimbursement rates and agency fee structures is unprofessional and involves confidential administrative details outside an RBT's operational responsibilities.

Behavior technicians implement behavior intervention plans but do not possess the clinical authority to modify them. Directing the caregiver to discuss the proposed modification with the supervising BCBA respects caregiver collaboration while maintaining proper clinical oversight. Modifying the written intervention plan immediately exceeds the technician scope of practice and violates supervision requirements. Agreeing to test the timeout procedure introduces an unapproved, unanalyzed consequence that could harm the client or worsen behavior. Informing the caregiver that timeout is strictly prohibited across all programs is factually inaccurate, as timeout can be an evidence-based intervention when properly designed and monitored by a BCBA.

During baseline skill assessments, the technician must maintain a neutral facial expression and neutral tone regardless of accuracy to evaluate true independent ability without providing inadvertent feedback. Delivering corrective feedback and modeling the correct response is incorrect because baseline probes must measure existing repertoires without teaching or prompting. Providing verbal praise for trying and repeating the prompt is incorrect because differential reinforcement or repeated prompts distort baseline accuracy measures. Offering a brief break and switching tasks right away is incorrect because altering the assessment protocol contingent on errors reinforces avoidance and disrupts standardized assessment procedures.

In an errorless learning procedure, the RBT provides a controlling prompt immediately following the instruction (discriminative stimulus) so the learner responds accurately without making an error. Waiting until after the learner attempts an incorrect word describes an error correction procedure rather than errorless teaching, which is specifically designed to preempt mistakes. Waiting five seconds for an independent answer describes a delayed prompt or least-to-most procedure, allowing room for errors to occur before assistance is delivered. Providing a prompt only when the learner vocally asks the technician for help requires prerequisite requesting skills and does not define an errorless teaching sequence.

When delivering necessary physical care during attention extinction, the RBT should remain completely silent and non-reactive to avoid accidentally reinforcing the challenging behavior with verbal attention or eye contact. Reassuring the client verbally provides adult attention, directly compromising the extinction procedure. Instructing the client to stand up engages them in verbal interaction and assumes the client can comply safely during a severe tantrum. Delivering a reprimand provides potent social attention and punishes rather than maintains extinction protocols.

In ABC data collection, the consequence component documents observable and measurable changes in the immediate environment that follow the target behavior, such as teacher reprimands or peer reactions. Perceived emotional states are internal, subjective inferences that cannot be directly observed or reliably measured by an RBT. Identifying what the teacher said before the behavior occurred describes the antecedent event, not the consequence. Summarizing why the student chose to escape assumes an unverified internal motivation and function; an RBT must record objective environmental events rather than subjective interpretations or functional hypotheses reserved for the supervising behavior analyst.

Self-monitoring procedural fidelity with an objective checklist helps the RBT evaluate their own clinical performance and identify specific areas where supervisory support or practice is needed. This practice fosters productive supervisory discussions and targeted skill acquisition. Self-monitoring does not replace the requirement for direct observation by a BCBA, which remains a mandatory component of ongoing monthly supervision. It does not authorize the technician to independently modify intervention protocols, as all treatment adjustments remain the sole responsibility of the BCBA. Furthermore, completing self-evaluations does not qualify an RBT to provide evaluative feedback to peers, which is a supervisory function reserved for qualified behavior analysts.

Session notes must objectively describe the observed physical signs and repeated requests for water, as these physiological variables directly influence client responding and well-being. Documenting that the client suffered from severe dehydration due to parental neglect at home makes unverified medical diagnoses and subjective accusations rather than recording factual observations. Recording that the client was irritable and deliberately manipulated the technician uses mentalistic, biased language that assumes intent. Omitting all physical observations to focus solely on target behaviors fails the requirement to record environmental and physiological variables that impact client performance, progress, and immediate safety during behavioral interventions.

When assessing receptivity to physical prompting, an RBT must immediately release the prompt and discontinue guidance if the client demonstrates active resistance, ensuring client safety, dignity, and voluntary assent. Applying firmer physical guidance to complete the motor movement is incorrect because forcing a client through resistance can cause injury, escalate distress, and violates ethical guidelines regarding bodily autonomy. Holding the client's hand firmly in position until resistance stops is incorrect because prolonged physical restraint is inappropriate and unsafe during skill assessments. Providing verbal redirection while continuing physical guidance is incorrect because physical pressure must not be maintained against active resistance.

Interspersing mastered maintenance tasks before presenting a challenging acquisition task creates behavioral momentum, also known as a high-probability instructional sequence, which increases compliance and reduces escape-maintained behaviors. Introducing several novel skills simultaneously is incorrect because maintenance tasks are already mastered, familiar behaviors rather than novel targets. Conducting a formal functional behavior assessment is an experimental or descriptive process conducted by a BCBA to identify behavioral function, not an instructional technique for running trials. Eliminating the requirement for reinforcement fading is incorrect because reinforcement must still be thinned systematically as the learner acquires mastery over new targets.

Protective blocking involves deflecting or creating a barrier against aggression without grasping or restraining the client. Mechanical restraint requires applying equipment or devices to limit movement, which was not used here. Physical restraint involves actively holding or grasping the client's body to restrict movement, whereas the technician merely deflected the strike without grasping. Response interruption and redirection is a proactive or reductive technique used primarily to disrupt repetitive behavior and redirect to an alternative activity, not a crisis self-defense response to an aggressive strike.

Attributing behavior to an internal mood produces circular reasoning: the client engaged in a tantrum because they were angry, and we know they were angry because they threw a tantrum. This mentalistic explanation fails to identify observable, measurable environmental antecedents and consequences that maintain the behavior. Caregivers can and should receive objective, factual updates about behaviors that occur during sessions. Internal moods are unobservable constructs and cannot be measured using whole-interval recording, which tracks observable behavioral occurrences. While BCBAs conduct functional assessments, RBTs are expected to communicate objectively about observable events rather than defaulting to mentalistic explanations.

Under BACB supervision requirements, a Board Certified Assistant Behavior Analyst (BCaBA) can serve as an RBT supervisor or requirements coordinator, but only if the BCaBA is actively supervised by a qualified Board Certified Behavior Analyst (BCBA). Requiring the BCaBA to own the clinical service agency is incorrect, as ownership has no bearing on supervision credentials. Holding a doctoral-level credential is required for a BCBA-D, not a BCaBA supervising RBTs. Finally, having five years of practice is not a BACB regulatory requirement for a BCaBA to supervise RBTs, provided the required ongoing BCBA supervision and supervisor training are maintained.

Documentation of safety devices must be precise, objective, and timely. Technicians must note the specific times and behavioral context when the helmet was utilized to provide an accurate record of safety protocol implementation and ensure regulatory compliance. Avoiding documentation of safety equipment under the guise of medical privacy violates documentation standards, as clinical notes are confidential legal records. Documenting that the client's aggressive family environment required restrictive equipment introduces subjective, unsupported speculation rather than objective data. Recording only the frequency of head-banging while omitting helmet application creates an incomplete record that obscures critical variables regarding physical restraint or protective gear utilization during sessions.

Conditioned reinforcers, such as points or tokens, derive their reinforcing value through pairing with established backup reinforcers. If they are repeatedly delivered without pairing or exchange opportunities, respondent extinction occurs and they will lose their reinforcing effectiveness. They will not become primary unconditioned reinforcers, as unconditioned reinforcers are innate biological needs like food and warmth that require no learning history. They will not significantly accelerate skill acquisition; instead, learner engagement and correct responding will decrease as the points lose value. They will not maintain compliance across all environments because an unbacked token system inevitably fails to motivate the learner over time.

Rolling their eyes and looking startled breaches attention extinction because nonverbal reactions—such as facial grimacing, gasping, or eye-rolling—function as social attention and can inadvertently reinforce the target behavior. Attention extinction requires withholding both verbal and nonverbal attention following the behavior. Continuing with the current task quietly correctly upholds the extinction protocol by avoiding social engagement. Recording the occurrence on the data sheet is an objective measurement duty that does not provide attention when conducted neutrally. Turning their body slightly away from the client is an acceptable, commonly used positioning strategy to minimize eye contact and prevent providing social feedback during planned ignoring.

When tracking total cumulative duration on a single digital timer without writing down interim numbers, resetting the device erases the running total of elapsed time recorded up to that point. Because the prior minutes of off-task behavior were not preserved elsewhere, that data is irretrievably lost for the session. An RBT cannot arbitrarily switch measurement systems to interresponse time mid-session, as IRT measures the time between consecutive behavioral episodes. Similarly, an RBT cannot retroactively convert duration into momentary time sampling, which requires recording behavior at specific preset intervals. Latency measures the delay before a behavior begins following a prompt, which was not the target measure.

RBTs must demonstrate cultural responsiveness by ensuring families receive accessible information in their primary language. However, translating clinical documents requires supervisory approval and professional accuracy; thus, the RBT must ask the supervising behavior analyst to provide translated tracking forms. Translating the written documentation independently using a free web application risks serious translation errors regarding clinical terms. Instructing the parents to use their own family interpreter places an inappropriate burden on the family and fails to provide culturally responsive service. Stopping daily tracking sheets during in-home visits is inappropriate because continuous objective data collection is required by the behavior plan.

When physical aggression occurs between clients and results in potential injury, the RBT must ensure immediate safety and promptly notify the supervising BCBA. Supervisors must be informed right away to evaluate safety protocols, document incidents, and adjust behavior support strategies. Creating a new intervention plan to prevent future peer aggression is incorrect because designing behavior intervention plans is a supervisor-level responsibility, not an RBT duty. Contacting the peer's family directly to discuss the incident violates client confidentiality guidelines and organizational communication protocols. Waiting to report the physical aggression at the weekly team meeting delays critical clinical communication, which compromises safety and prevents timely behavioral intervention.

Pairing praise with an established primary reinforcer, such as an edible, enables the neutral stimulus of praise to acquire reinforcing properties through stimulus-stimulus pairing, establishing it as a conditioned reinforcer. Reducing the total number of edible items consumed is incorrect because the primary goal of pairing during acquisition is conditioning praise, not caloric restriction. Preventing the client from becoming satiated on attention is incorrect because pairing praise with food does not prevent social satiation; rather, it conditions praise as a reward. Eliminating the need for systematic prompt fading is incorrect because reinforcer pairing affects motivational value and conditioned reinforcement, not the fading of antecedent prompts.

Speaking in a calm, neutral tone using a low volume helps de-escalate crisis situations by reducing environmental arousal and preventing behavioral contagion. Agitated clients often mirror the intensity and volume of staff. Speaking in a firm, authoritative tone with increased volume can elevate stress, escalate confrontation, and trigger aggressive defensive reactions. Repeating demands quickly overwhelms the individual and heightens agitation rather than providing space to regain self-regulation. Explaining classroom rules thoroughly using detailed logic requires complex verbal processing that an escalated client cannot effectively manage during an active crisis.

Fading prompts before a learner meets established mastery criteria removes needed guidance prematurely, causing learner errors to increase significantly. Without adequate prompt support, the client cannot consistently emit the correct response, leading to frustration and inaccurate responding. Developing prompt dependence is an incorrect choice because prompt dependence typically occurs when prompts are provided for too long or faded too slowly, not too quickly. Spontaneous generalization will not occur because the learner has not yet mastered the foundational skill. Target responses will not immediately extinguish, as extinction involves withholding reinforcement for previously reinforced behavior, which is not the procedure described here.

Participating in a social club or sports league organized by a client creates a multiple relationship that can compromise professional objectivity. RBTs must notify their supervisor about the invitation before making any commitment so that potential risks can be evaluated and appropriately mitigated. Accepting the invitation simply because games occur outside work hours ignores the inherent ethical conflict of interacting socially. Joining after securing family permission is insufficient because families cannot waive BACB ethics requirements. Refusing to speak with the client about non-clinical topics is unnecessarily rigid and damages rapport, whereas transparent supervisor communication properly resolves the ethical concern.

Changes in custody or living environments are significant contextual variables that influence client behavior, routine consistency, and service coordination. RBTs must promptly communicate custody schedule changes to the supervising BCBA so the administrative and clinical teams can verify consent, ensure consistent intervention, and update scheduling. Requesting official copies of the court custody decree directly from the mother is an administrative and legal responsibility handled by clinical leadership or agency administrators, not the technician. Creating separate behavior intervention plans for each caregiver's household is inappropriate because designing and modifying behavioral interventions is exclusively a BCBA responsibility. Advising the mother that alternating living environments disrupts therapy gains is unprofessional, judgmental, and outside the technician's role.

When validating a task analysis, technicians can perform the behavior personally to check for missing components, ensuring that every discrete step necessary for successful completion is included in the sequence. Asking the client's caregivers to complete the task analysis at home is incorrect because validation of clinical materials is the responsibility of the clinical team under BCBA supervision. Teaching the steps to an unassigned peer to evaluate their performance is incorrect because it risks confidentiality and exposes uninvolved clients to unvalidated procedures. Revising the mastery criteria independently prior to the session is incorrect because RBTs cannot alter clinical criteria or program designs without supervisor approval.

Automatic reinforcement is indicated when a behavior occurs at consistent, steady rates across all environmental conditions—including alone, play, demand, and attention—independently of social consequences. The behavior produces internal sensory stimulation that maintains it without external mediation. Social attention is ruled out because the behavior persists when social attention is absent and does not increase when attention is delivered. Task escape is ruled out because the behavior occurs equally during low-demand play conditions, not solely during academic demands. Access to tangibles is incorrect because the behavior does not depend on access to preferred items or activities.

Maintenance data assess whether a mastered behavior continues to occur at acceptable levels after formal instruction and contrived reinforcement have been discontinued. Plotting these data allows the clinical team to verify long-term retention of acquired skills. Establishing a baseline is incorrect because baseline data are collected before an intervention begins, not after mastery. Assessing performance across peers refers to stimulus generalization rather than maintenance over time. Determining reinforcer preference describes a preference assessment or reinforcer assessment, which is an unrelated procedure used to identify potential motivating items prior to or during teaching.

Practicing cultural humility involves honoring a family's cultural customs and domestic practices whenever feasible. Complying with the tradition unless doing so creates an immediate safety hazard demonstrates respect and responsiveness while protecting physical well-being. Refusing outright based on an alleged blanket prohibition is incorrect and culturally disrespectful, as no such absolute rule exists in behavior analysis. Asking the supervisor to issue a formal clinical exemption delays intervention unnecessarily over a standard home custom. Requiring the family to supply disposable shoe covers places an unfair burden on the household rather than adapting professionally to normative family practices.

An arbitrary stimulus class consists of stimuli that do not share common physical features or appearance but evoke the same functional response, such as pointing to an apple, sandwich, or milk when asked for food. A feature stimulus class is incorrect because it comprises stimuli that share common physical properties or forms, such as shape, color, or texture. A topographical stimulus class is incorrect because topography refers to the physical form of a response rather than a class of stimuli. A reflexive stimulus class is incorrect because reflexivity refers to matching identical stimuli in stimulus equivalence relations, not categorizing dissimilar stimuli under a common functional label.

Establishing the technician as a conditioned reinforcer is correct because pairing the technician's presence, voice, and instructional environment with preferred items establishes the technician as a conditioned reinforcer, building rapport before introducing demands. Assessing the client's baseline rate of challenging behavior is incorrect because pairing is an instructional rapport-building technique, not a baseline assessment phase. Conducting a formal multiple-stimulus preference assessment is incorrect because pairing involves freely sharing items, not systematically measuring item selection across structured trials. Implementing noncontingent reinforcement during academic tasks is incorrect because the technician is pairing during play and no academic demands are present.

Using conditioned reinforcers such as praise and tokens allows instruction to proceed without stopping for edible items, facilitating the fluid execution of behavioral chains like handwashing or tooth brushing. Eliminating the requirement to collect task analysis data during trials is incorrect because data collection remains mandatory regardless of reinforcer type. Guaranteeing that the client will never experience reinforcer satiation is incorrect because conditioned reinforcers can also lose effectiveness if overused, though they satiate more slowly than primary reinforcers. Preventing the learner from engaging in escape-maintained behaviors is incorrect because conditioned reinforcers do not guarantee error-free responding or completely eliminate escape-maintained behavior.

A curve that gradually flattens to horizontal is correct because on a cumulative record, data points never decrease; a flat, horizontal slope indicates zero responding, demonstrating that extinction has successfully extinguished the behavior. A line that steepens steadily upward is incorrect because an increasing slope on a cumulative record indicates an increasing rate of responding. A series of jagged vertical spikes is incorrect because cumulative lines can only rise or stay flat, never spike up and down. A line that drops steadily toward zero is incorrect because cumulative graphs never drop or have a negative slope, as responses accumulate over time.

Positive reinforcement involves the presentation of a stimulus immediately following a response, which increases the future probability or frequency of that response in similar conditions. Here, delivering a high-five increased the client placing their backpack in the cubby. Negative reinforcement is incorrect because negative reinforcement increases behavior through the contingent removal, termination, or reduction of an aversive stimulus. Positive punishment is incorrect because punishment procedures decrease the future frequency of a behavior rather than increasing it. Negative punishment is incorrect because negative punishment decreases future behavior through the contingent removal or reduction of an appetitive stimulus.

The best action is to adjust the angle of the materials to eliminate glare from the overhead lights, ensuring that environmental factors do not impede the learner's ability to clearly see the visual stimuli. Having the client wear protective sunglasses throughout the instructional session is incorrect because modifying the client's attire is unnecessary, intrusive, and does not address the environmental glare directly. Implementing an extinction procedure for incorrect responses during the matching task is incorrect because errors caused by visual obstruction require antecedent environmental modifications, not extinction. Asking the supervisor to immediately replace the matching program with vocal tacting is incorrect because technicians should resolve environmental barriers before abandoning established treatment goals.

Stimulus equivalence describes the emergence of untrained stimulus-stimulus relations following the explicit reinforcement of related conditional discriminations (e.g., if A=B and B=C, then A=C emerges without direct training). Response generalization is incorrect because it involves emitting untrained topographically different behaviors that serve the same function, rather than responding to untrained stimulus relations. Stimulus fading is incorrect because it refers to the systematic and gradual removal of physical dimensions of a prompt or stimulus. Behavioral contrast is incorrect because it describes a change in the rate of responding in one setting when the reinforcement schedule in another setting changes.
