RBT® Terminology Glossary (A–Z)

ABA stands for Applied Behavior Analysis. It refers to the field of behavioral science in which individuals learn to apply the principles of behavioral theory to provide behavioral assistance to improve the societal living standards.

For example – an RBT works to implement the ABA-specific theories to analyze and determine behavioral patterns of at-risk clients so that they might arrange for interventions and use positive reinforcement to guide them.

The full form of ABC is Antecedent – Behavior – Consequence.

These three concepts make up the 3-term contingency. Antecedent drives the behavior in discussion. This behavior, in turn, drives the consequence.

ABC Recording refers to a narrative method of noting down the Antecedent, Behavior, and Consequence as they happen during observation. It helps the RBT and BCBA identify the function behind a behavior.

Abolishing Operation refers to when there's a decrease in reinforcer effectiveness. When there's an overlap in various procedures or reinforcements, the positive effect can reduce due to the multiplicity.

The term acquisition itself refers to the subject that's being coached/taught.

For instance – to teach a child how to write alphabets, identify vowels, etc. Here, the act of teaching these materials is the acquisition in action.

Acquisition Task refers to the RBT's task or target at hand.

For example – an RBT assists a kid with ADHD to spell properly. Here, the acquisition task is to help the child with his vocabulary and spelling.

Active Listening refers to fully focusing on, understanding, and responding to what others communicate. It strengthens the RBT's collaboration with both clients and supervisors.

The literal meaning of antecedent is something that existed previously. As in, the previous condition of the current event or precedence.

In the RBT world, it can refer to the environmental condition, stimulus status, or any change of stimulus just prior to the behavior/emotion of interest.

For example – a child throws a hysterical fit right after his mother takes away the TV remote from him. Here, the antecedent is the action of taking away the remote that leads to the surge of strong emotions in the child.

Antecedent interventions refer to the identification of relevant environmental factors that lead to toxic/problematic behavior. These factors are considered as triggers. Necessary interventions are then arranged to reduce the amount of these triggers or to eliminate them entirely.

For instance – if a child is bothered by the presence of a certain image of a person, animal, etc. due to past trauma, then the necessary antecedent intervention is to ensure a complete erasure of that image from their life.

Assent refers to a client's voluntary willingness to participate in a session or activity, even when they can't legally give consent. RBTs should always watch for signs of assent withdrawal and respect them.

Automatic Reinforcement refers to reinforcement that a behavior produces on its own, without anyone else being involved. For instance – a child hums to themselves because the sound feels soothing.

Backward chaining refers to the process of teaching a program by starting from the last step and then making your way to the top.

Baseline refers to the initial data collected before any intervention takes place. It acts as a reference point to measure progress later on. For instance – recording how often a child hits before starting a behavior plan.

BCBA stands for Board Certified Behavior Analyst and BCaBA for Board Certified Assistant Behavior Analyst. They design and supervise the treatment plans that RBTs implement in the field.

In RBT, behavior refers to observable and measurable behavior. That is, anything that a person does falls under the category of behavior, as long as it can be observed and measured by behavioral analysts.

In RBT, behavior serves four major functions. Firstly, it provides automatic and sensory relief via self-stimulation. Secondly, it provides a sense of escape from problematic and undesirable situations. Thirdly, it's a form of attention that people seek for validation. And lastly, it allows people access so that they can want and secure a preferred item or objective.

BIP or Behavior Intervention Plan is curated based on antecedent strategies. This plan involves identification of maladaptive behavior and implementation of replacement behavior. Interventions can be both verbal and physical.

BST or Behavior Skills Training primarily covers four areas of training – 1) Instruction, 2) Modeling, 3) Behavior Rehearsal, and, 4) Feedback. These are used to introduce or teach new behavior or skills to at-risk individuals.

Behavioral Contract refers to a written agreement between the subject and the RBT/caregiver that outlines the expected behaviors and the rewards tied to them. It's also called a contingency contract.

Behavioral Contrast refers to when a change in reinforcement in one setting causes an opposite change in behavior in another setting.

Behavioral Cusp refers to a behavior that, once acquired, opens the door to new opportunities and environments. For instance – learning to read unlocks countless new skills down the line.

Chaining refers to when a procedure contains multiple steps and they are all interconnected. Each step forms a bond with one another. Completing all of the steps forms a proper chain. Chaining can be both forward and backward.

Client Dignity refers to treating every client with respect, compassion, and consideration regardless of their behavior or circumstances.

Collaboration refers to working effectively alongside supervisors, caregivers, and other professionals to support the client's progress as a team.

Competence refers to providing only those services that an RBT has been properly trained to deliver. Working beyond one's competence violates ethical guidelines.

Conditioned Punisher refers to a stimulus that becomes punishing only after being paired with an already established punisher. For instance – the word "no" said sternly.

Conditioned Reinforcer refers to a stimulus that becomes reinforcing through repeated pairing with an already established reinforcer. For instance – money or tokens.

Confidentiality refers to the RBT's duty to keep all client information private and share it only with authorized individuals.

Conflict of Interest refers to a situation where an RBT's personal interests could interfere with their professional duties or the client's well-being.

Consequence refers to the event that comes after behavior. In RBT, consequences are often problematic and have a negative connotation.

For instance – due to overstimulation, a child breaks the TV remote. Here, the action of breaking the TV remote is the consequence while the aggressive behavior beforehand is the resultant of the overstimulation/antecedent.

Contingency refers to the dependent relationship between a behavior and its consequence. The consequence only occurs if the behavior happens first.

In continuous measurement, every single occurrence of a behavior is measured for data analysis. It involves frequency, duration, rate, etc.

Reinforcement, whether positive or negative, is continuously enforced to implement the target behavior after every occurrence. For instance – every time a child starts to get overwhelmed, they are reminded to implement a self-soothing technique as a form of continuous reinforcement.

Crisis Procedures refer to the predetermined steps an RBT follows to keep everyone safe during a behavioral emergency. RBTs must always follow the BCBA-approved protocol rather than improvising.

Cultural Humility refers to an ongoing, self-reflective approach where the RBT acknowledges their own biases and respects each client's cultural background. It's a continuous process rather than a one-time achievement.

Cultural Responsiveness refers to the RBT's ability to adjust their behavior and services to respect the cultural values, beliefs, and needs of the client and their family.

Cumulative Record refers to a graph where data is continuously added on top of the previous total. The line never goes down — it only rises or stays flat — showing total responses over time.

Data Privacy refers to protecting client information from unauthorized access or disclosure. RBTs must store and share data only through secure, approved channels.

De-escalation refers to the strategies used to safely calm a subject and reduce the intensity of a crisis or an escalating behavior.

Deprivation takes place when the subject is unable to have a certain thing with ease. So, when that particular thing is (ethically) used as a reinforcer, it usually raises the effectiveness of the reinforcement strategies.

In Differential Reinforcement, RBTs extinguish other forms of reinforcement to actively implement one particular type of reinforcement for effectiveness.

Direct Measurement refers to recording a behavior as it actually happens, in real time, while the RBT observes the subject directly. It's considered highly accurate since it doesn't rely on memory or secondhand reports. For instance – tallying each time a child leaves their seat during the session itself.

DISC is an acronym used to remember the four factors that determine how effective a reinforcer will be – Deprivation, Immediacy, Size, and Contingency.

Deprivation means the client hasn't had access to the reinforcer recently, so they're more motivated to earn it. Immediacy means the reinforcer is delivered right after the target behavior so the client links the reward to the action. Size (or magnitude) means the reward is big enough to be worth it, but not so big that it causes satiation. And Contingency means the reinforcer is given if and only if the target behavior occurs, so the client can't access it for free.

In Discontinuous Measurement, RBTs measure some instances of behavior specifically instead of all parameters. Relevant parameters include – partial Interval recording, whole interval recording, momentary time sampling, etc.

In a Discrete Trial, the RBT or the reinforcer employs the 3 contingencies of ABC to ensure and initiate learning opportunities for the patient. At the same time, he controls the outcomes by only registering the correct responses.

For instance – the child isn't presented with a reward until they showcase positive behavior or complete the desired task.

In Discrimination Training, the RBT allows the presence of multiple stimuli so that the patient learns to adapt to the uncertainties of their surroundings.

SD, or Discriminative Stimulus refers to the cue or signal that indicates that it's time for reinforcement based on particular responses of the subject.

For instance – a subject that struggles with loud noise is slowly exposed to such an environment. His rash/rude behavior indicates that it's time to bring in a reinforcement to subside his emotional outburst.

DRA stands for Differential Reinforcement of Alternative Behaviors. Here, RBTs ensure that the patient replaces the undesirable behavior with an acceptable or a positive one. For instance – a child has a bad habit of biting the mouth caps of the pens. So, the RBT reinforces him to stop chewing unhealthy items by replacing the behavior with something else such as chewing gums.

DRH stands for Differential Reinforcement of High Rates. Here, the subject is reinforced for increasing the frequency of a desirable behavior. For instance – answering more questions during a lesson.

DRI stands for Differential Reinforcement of Incompatible Behaviors. Here, RBTs encourage patients to complete the desired task/behavior by guiding them/nudging them in the right direction.

For instance – an RBT reinforces a child to complete their homework instead of being engaged in unproductive leisurely activities. Here, RBTs work on incompatible behaviors to ensure they're focusing on desirable behaviors.

DRL stands for Differential Reinforcement of Low Rates. Here, the subject is reinforced for reducing the frequency of a behavior rather than eliminating it entirely. For instance – raising a hand fewer times in class.

DRO stands for Differential Reinforcement of Other Behaviors. If the previous two forms of reinforcement fail to take effect, RBTs work to engage the patient in any other form of behavior other than the undesirable one.

For instance – every 10-15 minutes, the RBT gives a small piece of sugar-free chocolate or gummy bear to the kid so that he doesn't throw a fit or cry.

Dual Relationship refers to when a doctor shares multiple relationships with the patient/client/subject or their parents/social caregivers. Usually, dual relationships come into existence via roleplay sessions with the subject.

Duration refers to the particular amount of time that a person engages in a certain behavior. For instance – the outburst of a subject lasts for around 40 seconds. Here, 40 seconds is the duration of the behavior.

Echoic here refers to its literal meaning. When the RBT i.e. the behavioral therapist repeats the subject's words, it's deemed as echoic. Usually, it's conducted so that the subject realizes the gravity of his own words/actions.

The full form of ECTER is Error, Connection, Transfer, Expand, and Return. It's a continuous process where the therapist reorganizes a trial to ensure that the subject is able to realize his mistakes on his own without extra interventions.

Error refers to the mistake or undesirable stimulus itself, Connection refers to the therapist's attempt to represent the SD or Discriminative Stimulus with prompt, Transfer refers to when the therapist can do it without a prompt, Expand refers to the therapist can place easy or already mastered demands/activities in lieu of the Error, and lastly, Return takes effect when the subject is reinforced to complete the desirable task instead of the Error one.

Errorless Teaching takes place when the subject is not even given a chance to make a mistake. As soon as the prompt is given, the therapist also provides or redirects the subject to the correct response instantaneously.

Establishing Operation or, EO, refers to when deprivation is employed to increase the effectiveness of a certain reinforcement strategy.

In RBT, Ethics refers to the BACB's ethical code of conduct or code of ethics. Mismanagement of these ethical guidelines can directly result in loss of employment and RBT certification for the Technician.

Expressive language refers to the ability of effective communication. When a subject is able to express their feelings, emotions, etc. in a healthy and accurate manner, it's said that he/she is capable of expressive language.

Extinction refers to the process of reducing a previously reinforced behavior by no longer providing reinforcement. Over time, the behavior decreases or stops.

Example: If a child throws tantrums to gain attention and the RBT consistently ignores the tantrum, the behavior may eventually diminish.

An extinction burst is a temporary increase in the frequency, intensity, or duration of a behavior after extinction has been implemented.

Example: A child may initially scream louder or throw objects when their tantrums are ignored before the behavior decreases.

A systematic process to identify the causes and functions of a behavior.

Example: An FBA may reveal a child bites peers to gain attention.

A schedule of reinforcement where the first response is reinforced after a fixed amount of time has passed.

Example: A child receives praise for checking their homework every 10 minutes.

Fluency refers to performing a skill both accurately and quickly. It indicates that the subject has truly mastered the behavior, not just learned it.

Teaching a behavior by starting with the first step and then adding subsequent steps once mastery is achieved.

Example: Teaching handwashing: first the child learns to turn on the tap, then soap, then rinse, step by step.

Four-Term Contingency refers to the ABC model plus the Motivating Operation that sets the stage for it. It adds the "why now" element to Antecedent-Behavior-Consequence.

A schedule of reinforcement where a response is reinforced only after a specific number of responses.

Example: A child earns a sticker after completing 5 math problems.

In a Free-Operant Preference Assessment, the subject is allowed to freely interact with available items without any restrictions. The RBT simply observes which items they engage with the most and for how long.

The number of times a behavior occurs within a given observation period.

Example: A child raises their hand 10 times in a 30-minute class session.

Functional Analysis refers to the systematic process of manipulating antecedents and consequences to directly identify the exact function of a behavior. Note – RBTs may assist with this, but they don't conduct it independently.

FCT refers to teaching the subject an appropriate communication response to replace a problem behavior. For instance – teaching a child to ask for a break instead of screaming.

A connection between a behavior and its controlling variables, showing how changes in antecedents or consequences affect behavior.

Example: Removing a preferred toy (antecedent) leads to tantrums, showing a functional relationship between the antecedent and behavior.

Behaviors generally serve four primary functions: Attention, Escape, Access to Tangibles, Automatic/Sensory.

Example: A child may hit to gain attention (social function) or engage in hand-flapping for sensory satisfaction (automatic function).

The ability of a learned behavior to occur across different settings, people, or stimuli.

Example: Teaching a child to say "hello" with one therapist, and the child also says it to their teacher and parent.

Generalized Conditioned Reinforcer refers to a conditioned reinforcer that has been paired with many different reinforcers. For instance – tokens or money, which can be exchanged for a wide range of items.

Gestural Prompt refers to a cue given through gestures such as pointing, nodding, or motioning. It guides the subject without any physical contact or words.

Gift-Giving refers to the exchange of gifts between an RBT and a client or their family. To maintain professional boundaries, RBTs generally avoid giving or accepting gifts.

Also called behavioral momentum, this refers to presenting a series of easy requests the subject is likely to comply with before introducing a harder one. It builds compliance momentum.

Health Insurance Portability and Accountability Act. RBTs must protect client confidentiality and comply with HIPAA regulations.

Copying another person's behavior. It is a critical skill in teaching language and social behaviors.

Example: A child claps after seeing the therapist clap.

Learning that occurs naturally during daily routines or play rather than in structured lessons.

Example: Teaching the child to request "ball" when playing fetch.

Informed Consent refers to the formal permission given by a client or guardian after fully understanding the services involved. It's both a legal and an ethical requirement.

The ability of the RBT to establish a learning environment where the client responds appropriately to instructions.

Example: The client completes tasks consistently when given clear, structured instructions.

Reinforcing behavior only some of the time.

Example: Praising a child occasionally for raising their hand, rather than every time, helps maintain behavior long-term.

IOA refers to the degree to which two or more independent observers report the same values after measuring the same behavior. It's used to confirm that the collected data is reliable and accurate.

The time between two consecutive responses of a behavior.

Example: A child taps the desk twice, with 5 seconds between each tap.

Interspersal Training refers to mixing already-mastered tasks in with new ones to keep the subject motivated and reduce frustration during learning.

A type of verbal behavior where a response is controlled by a verbal stimulus with no point-to-point correspondence.

Example: Therapist asks, "What's your name?" and the child says, "John."

The time between the presentation of a stimulus and the initiation of the response.

Example: Time from "clap your hands" to when the child actually starts clapping.

In Least-to-Most Prompting, the RBT begins with the least intrusive prompt and only increases the level of assistance if the subject struggles to respond.

Level refers to the value of the data on the vertical axis of a graph. It indicates the average amount of behavior within a particular phase.

Line Graph refers to the most common way ABA data is displayed. Individual data points are plotted and connected to show behavior change over time.

Responding appropriately to someone else's verbal instruction or question.

Example: Child touches the "ball" when asked, "Show me the ball."

A systematic way to teach and assess verbal skills: Labeling objects, Receptive identification, and Feature, Function, Class categorization.

The intensity or force of a behavior.

Example: Soft vs. hard hitting when a child throws an object.

Maintaining Certification refers to the ongoing requirements — like supervision, renewal, and ethics compliance — that an RBT must meet to keep their credential active.

Maintenance refers to the ability of a subject to retain and perform a learned skill even after the formal teaching has ended.

Maladaptive Behavior refers to any behavior that interferes with a subject's learning, safety, or daily functioning. These are the behaviors typically targeted for reduction.

Mand refers to a type of verbal behavior where the subject requests something they want or need. It's motivated by deprivation or desire. For instance – a child says "water" because they're thirsty.

Mandated Reporter refers to an RBT's legal obligation to report any suspected abuse or neglect of a client to the appropriate authorities.

Mass Trial refers to presenting the same target repeatedly until the subject responds correctly and consistently. It's often the first step in teaching a brand-new skill.

Mastery Criteria refers to the predetermined standard a subject must meet to be considered as having learned a skill. For instance – 90% accuracy across three consecutive sessions.

Model Prompt refers to when the RBT demonstrates the desired behavior so that the subject can imitate it. For instance – showing the child how to stack blocks before they try.

Momentary Time Sampling refers to recording whether a behavior is occurring at the exact end of a specific interval. The RBT isn't required to observe the behavior throughout — just at that precise moment.

In Most-to-Least Prompting, the RBT starts with the most intrusive prompt and gradually reduces the level of assistance as the subject improves.

Motivating Operation refers to any factor that temporarily alters the effectiveness of a reinforcer and the behavior linked to it. It includes both establishing and abolishing operations.

MSWO stands for Multiple Stimulus Without Replacement. Here, multiple items are presented at once, and once the subject picks one, that item isn't replaced. The process repeats to create a ranking of preferences.

Multiple Exemplar Training refers to teaching a skill using a variety of examples so the subject can generalize it across different situations.

Multiple Relationships refer to situations where an RBT holds more than one type of relationship with a client. These can blur professional boundaries and should be avoided.

NET refers to teaching skills within the subject's natural surroundings and daily routines instead of a structured table setting. Learning happens through play and real-life situations.

Negative Punishment refers to removing a preferred stimulus after a behavior to reduce it. For instance – taking away screen time after a tantrum.

Negative Reinforcement refers to removing an unpleasant stimulus after a behavior to increase its future occurrence. For instance – turning off a loud alarm once a task is completed.

NCR refers to delivering reinforcement based on time rather than behavior. The reinforcer is given regardless of what the subject does, often to reduce problem behavior.

Operational Definition refers to a clear, objective, and measurable description of a behavior. It removes any room for assumption so that anyone can identify the behavior the same way.

In a Paired Stimulus Preference Assessment, items are presented two at a time so the subject can choose between them. By repeating the pairs, the RBT figures out the most preferred item. It's also called a forced-choice assessment.

Pairing refers to the process of associating the RBT or the learning environment with preferred items and positive experiences. It builds rapport and makes sessions enjoyable.

Partial Interval Recording refers to a discontinuous measurement where the RBT notes whether a behavior occurred at any point during an interval. It doesn't matter how many times it happened, as long as it occurred once. It tends to overestimate the behavior.

Permanent Product refers to the tangible outcome or evidence left behind after a behavior takes place. The RBT measures the result instead of watching the behavior directly. For instance – counting the number of completed worksheets.

Personal Bias refers to the unconscious assumptions or preferences an RBT might hold. Recognizing and managing these biases is essential to delivering fair and ethical services.

PHI stands for Protected Health Information. It includes any identifiable client health data that RBTs are legally required to keep confidential under HIPAA.

Physical Prompt refers to physically guiding the subject to complete a task. It can be full (hand-over-hand) or partial (a light nudge), depending on the level of help needed.

Pivotal Behavior refers to a key behavior that, once learned, leads to improvements across many other behaviors. For instance – building motivation can boost overall learning.

Positional Prompt refers to placing the correct item closer to the subject to increase the chances of them choosing it correctly.

Positive Punishment refers to adding an unpleasant stimulus after a behavior to reduce it. For instance – assigning extra chores after misbehavior.

Positive Reinforcement refers to adding a pleasant stimulus after a behavior to increase its future occurrence. For instance – giving praise after a child shares a toy.

Preference Assessment refers to the process of identifying which items, activities, or stimuli a subject prefers the most. These preferred items are then used as potential reinforcers during sessions.

Premack Principle refers to using a high-probability (preferred) activity to reinforce a low-probability (less preferred) one. For instance – "finish your homework, then you can play."

Probe refers to a quick test or check to assess whether a subject has acquired or retained a particular skill. It's usually conducted without any prompts or reinforcement.

Professional Boundaries refer to the limits that keep the RBT-client relationship strictly professional. Crossing them — through gifts, friendships, or favors — is discouraged.

Professional Demeanor refers to maintaining appropriate behavior, appearance, and communication while representing oneself as an RBT.

Prompt refers to a cue or assistance provided by the RBT to help the subject produce the correct response. It increases the chances of success during learning.

Prompt Dependency refers to when a subject relies too heavily on prompts and struggles to respond independently without them. It's something RBTs actively work to avoid.

Prompt Fading refers to the gradual removal of prompts over time so that the subject can respond independently. The goal is to prevent prompt dependency.

Prompt Hierarchy refers to the structured order of prompts arranged from most to least intrusive, or vice versa. It guides the RBT on how much help to provide and when.

Punishment refers to any consequence that decreases the likelihood of a behavior occurring again. It can be either positive or negative.

Random Rotation refers to presenting multiple targets in an unpredictable order to confirm that the subject has truly mastered each one.

Rate refers to the number of times a behavior occurs within a specific time frame. Unlike frequency, it always accounts for the time element. For instance – a child claps 12 times in 4 minutes, so the rate is 3 claps per minute.

Receiving Feedback refers to an RBT's ability to accept input from supervisors gracefully and use it to improve their practice. It's a key professional skill emphasized in the 3rd Edition outline.

Receptive Language refers to the ability to understand and respond to the language of others. For instance – a child points to the correct picture when asked "Where is the apple?"

Reinforcement refers to any consequence that increases the likelihood of a behavior occurring again in the future. It can be either positive or negative.

Reinforcer refers to the actual stimulus or event that strengthens a behavior. If it increases the behavior, it qualifies as a reinforcer.

Reinforcer Assessment refers to the process of confirming whether a particular item or activity actually increases the target behavior. It goes a step beyond preference by testing real effectiveness.

Reinforcer Sampling refers to giving the subject a small taste or preview of a reinforcer to boost their motivation to work for it.

Replacement Behavior refers to an appropriate behavior taught to take the place of a problem behavior. It usually serves the same function as the undesired one.

Response refers to a single instance of a behavior. It's one occurrence of the action being observed or measured.

Response Blocking refers to physically preventing the subject from completing an undesired or harmful behavior. For instance – blocking a child's hand to stop them from hitting.

Response Cost refers to removing a specific amount of a reinforcer following an undesired behavior. For instance – losing a token each time a rule is broken.

Response Generalization refers to when a subject uses different responses to achieve the same outcome after learning one. For instance – a child learns to say "hi" and then also begins to wave or say "hello."

Response Prompt refers to the assistance given directly to the subject's response, such as verbal, gestural, model, or physical prompts.

Resurgence refers to the reappearance of a previously reinforced behavior when a newer behavior stops being reinforced.

Satiation refers to a state where a reinforcer loses its effectiveness because the subject has had too much of it. For instance – snacks stop working as a reward right after a big meal.

Scatterplot refers to a data recording tool used to identify patterns in behavior across time. It helps spot when a behavior is most likely to occur.

Schedule of Reinforcement refers to the rule that determines how and when a behavior gets reinforced. It can be continuous or intermittent.

Scope of Practice refers to the specific tasks and responsibilities an RBT is authorized to perform. Stepping outside this scope is an ethical violation.

Session Notes refer to the written record an RBT completes after each session. They document what happened, the data collected, and the client's response to interventions.

Setting Event refers to a condition or event that happens before the antecedent and increases the likelihood of a problem behavior. For instance – poor sleep making a child more irritable.

Shaping refers to the process of reinforcing small steps that gradually get closer to the desired target behavior. Each successful approximation is rewarded until the full behavior is achieved.

Social Media Boundaries refer to the professional limits an RBT must maintain online. For instance – not connecting with clients on personal accounts or sharing any client information.

Social Validity refers to how acceptable, meaningful, and useful the goals, procedures, and outcomes of an intervention are to the client and their caregivers.

Spontaneous Recovery refers to the sudden reappearance of a previously extinguished behavior after some time has passed. It usually happens without any new reinforcement.

Stakeholder refers to anyone invested in the subject's progress, such as parents, caregivers, teachers, or other professionals involved in their care.

Stimulus Control refers to when a particular behavior reliably occurs in the presence of a specific stimulus. The stimulus essentially signals when the behavior should happen.

Stimulus Generalization refers to when a learned behavior occurs in the presence of stimuli similar to the original one. For instance – a child taught to identify one dog recognizes other dog breeds too.

Stimulus Prompt refers to altering the stimulus itself — through size, color, or position — to make the correct answer more obvious.

Successive Approximations refer to the small, incremental steps that lead towards the final target behavior during the shaping process. Each step is slightly closer to the goal than the last.

Supervision Requirements refer to the BACB's rule that RBTs must work under ongoing supervision for a set percentage of their service hours. RBTs can never practice independently.

Tact refers to a verbal behavior where the subject labels or names something in their environment. It's driven by contact with the stimulus rather than a need. For instance – a child says "dog" upon seeing a dog.

Tangible refers to a function of behavior where the subject acts in order to gain access to a preferred item or activity. For instance – a child cries to get a toy.

Target Behavior refers to the specific behavior selected for observation, measurement, or intervention. It can be a behavior to increase or one to decrease.

Task Analysis refers to the process of breaking down a complex skill into smaller, teachable steps. These steps are then taught one by one. For instance – breaking down "brushing teeth" into individual actions.

Textual refers to a verbal behavior where the subject reads written words out loud. There's point-to-point correspondence but no need for comprehension. For instance – reading the word "cat" aloud from a flashcard.

Three-Term Contingency refers to the relationship between Antecedent, Behavior, and Consequence (ABC). It forms the foundation of understanding behavior in ABA.

Time Delay refers to inserting a planned pause between the instruction and the prompt. It gives the subject a chance to respond independently before help is offered.

Time-Out refers to removing the subject from a reinforcing environment for a brief period following undesired behavior. It reduces the behavior by cutting off access to reinforcement.

Token Economy refers to a reinforcement system where the subject earns tokens for desired behaviors. These tokens are later exchanged for a preferred item or activity.

Topography refers to the physical form or appearance of a behavior — basically what it looks like. For instance – describing a tantrum as kicking, screaming, and falling to the floor.

Total Task Presentation refers to a chaining method where the subject is guided through every step of a task in each session. Prompts are provided wherever necessary until mastery.

Transcription refers to a verbal behavior where the subject writes or spells words in response to a spoken word. It's essentially the written counterpart of an echoic.

Treatment Integrity refers to the degree to which an intervention is carried out exactly as the BCBA designed it. Also called procedural fidelity, it's crucial since RBTs must never modify a plan on their own.

Trend refers to the overall direction in which the data is moving on a graph over time. It can be increasing, decreasing, or flat. RBTs use it to gauge whether an intervention is working.

Trials to Criterion refers to the number of attempts a subject needs before they finally master a particular skill or task. It helps the RBT measure how quickly learning takes place. For instance – a child takes 8 trials to correctly identify all the colors.

Unconditioned Punisher refers to a stimulus that is naturally punishing without any learning. For instance – extreme heat, pain, or a sudden loud noise.

Unconditioned Reinforcer refers to a stimulus that is naturally reinforcing without any prior learning. For instance – food, water, or sleep.

Variability refers to how much the data points differ from one another on a graph. High variability means the behavior is inconsistent, while low variability indicates stability.

Verbal Behavior refers to any behavior that is mediated by another person and reinforced socially. It covers communication forms like mands, tacts, echoics, and intraverbals.

Verbal Operant refers to the individual units or categories that make up verbal behavior. Each operant — mand, tact, echoic, etc. — serves a different communicative function.

Verbal Prompt refers to a spoken cue or instruction that helps the subject produce the correct response. For instance – saying "say thank you" to remind the child.

VI refers to a reinforcement schedule where the first response is reinforced after varying amounts of time. The unpredictability keeps the behavior steady.

Visual Analysis refers to the process of examining graphed data to make sense of trends, levels, and variability. It helps determine whether an intervention is working.

Visual Prompt refers to using pictures, charts, or written cues to guide the subject toward the correct response.

VR refers to a reinforcement schedule where a behavior is reinforced after an unpredictable number of responses. For instance – slot machines work on a VR schedule.

In Whole Interval Recording, the RBT records the behavior only if it lasts for the entire duration of the interval. If the behavior stops midway, it isn't counted. This method usually underestimates the behavior.
