Behavioral Definitions and Classification Systems

• Subjective versus Objective Behavioral Definitions:
  • Subjective Definition: Characterized by internal emotional states, non-observable descriptions, or vague labels.
  • Subjective Example: Describing a client as "getting frustrated" when yelling and crying.
  • Objective Definition: Defined strictly by measurable, observable physical acts and measurable parameters with explicit inclusionary and exclusionary criteria.
  • Operational Example: Any instances in which the client engages in $2$ or more of the following behaviors: yelling, crying, and/or dropping to the floor for at least $1\,\text{min}$.
  • Exclusionary Conditions: Does not include yelling while playing games or sitting on the floor for activities or games.
• Overt versus Covert Behaviors:
  • Overt Behaviors: Actions that are directly observable by an outside observer (e.g., opening a bag of peanuts).
  • Covert Behaviors: Internal behaviors or private events that cannot be directly observed by others (e.g., thinking about how peanuts will taste).
• Target Behavior Standards:
  • Definition: The specific behavior selected for modification, reduction, or skill acquisition within a behavioral intervention program.
  • Objective: Refers only to observable characteristics of the behavior and translates to unambiguous clinical descriptions.
  • Clear: Unambiguous and easily understood so that an unfamiliar observer could read the definition and consistently identify the occurrence.
  • Complete: Outlines the exact boundaries of what constitutes an instance of the behavior, explicitly detailing both inclusions and exclusions.
  • Observable: Involves actions or events that can be detected through sensory modalities (e.g., seen or heard).
  • Measurable: Can be quantified using standard dimensions such as frequency, duration, rate, latency, or inter-response time.

Functions of Behavior and the ABC Contingency Framework

• The Four Functions of Behavior:
  • Automatic / Sensory Behaviors:
  • Underlying Purpose: Self-reinforcing behavior that generally does not require access to or assistance from others, maintained by internal sensory input.
  • Manifestations: Repetitive motor movements, such as rocking, hand flapping, and related stereotypies.
  • Escape Behaviors:
  • Underlying Purpose: Carried out to avoid or delay an undesired or non-preferred task, person, activity, or location.
  • Common Manifestations: Elopement, tantrums, and dropping to the floor.
  • Attention-Maintained Behaviors:
  • Underlying Purpose: Carried out to gain attention, social reaction, or acknowledgment from others.
  • Common Manifestations: Throwing objects, hitting, crying, and spitting.
  • Tangible-Maintained Behaviors:
  • Underlying Purpose: Carried out to gain physical access to preferred items, activities, locations, or people.
  • Common Manifestations: Tantrums, physical aggression, and yelling.
• The ABC Contingency Framework:
  • Antecedent ($A$): Environmental conditions, stimuli, or events that happen immediately before the behavior occurs.
  • Behavior ($B$): What the behavior looks like; the topography, physical form, and observable action exhibited by the client.
  • Consequence ($C$): Environmental modifications, stimuli, or events that happen immediately after the behavior occurs.
  • Worked Clinical Scenario:
  • Antecedent: Clinician instructs the client to go potty.
  • Behavior: Client dropped to the floor and yelled, "I want to go outside!!".
  • Consequence: Clinician tells the client to go potty first, then outside; the client subsequently goes potty.

Operant Principles of Reinforcement and Punishment

• Core Behavioral Definitions:
  • Reinforcement: An environmental contingency designed functionally to increase or maintain the future probability, frequency, or intensity of a target behavior.
  • Punishment: An environmental change occurring immediately following a behavior that functions strictly to decrease the future frequency, rate, or likelihood of that behavior.
• The Four Operant Contingencies:
  • Positive Reinforcement: The addition or presentation of a stimulus following a response, resulting in an increase or maintenance of the behavior in the future.
  • Negative Reinforcement: The removal, reduction, or termination of a stimulus following a response, resulting in an increase or maintenance of the behavior in the future.
  • Positive Punishment: The addition or presentation of a stimulus immediately following a response, which decreases the likelihood of that behavior occurring in the future.
  • Negative Punishment: The removal or withdrawal of a stimulus immediately following a response, which decreases the likelihood of that behavior occurring in the future.
• Core Behavioral Rule of Separation:
  • A stimulus and a behavior cannot be the same entity.
  • A stimulus is an external or environmental event, condition, or change.
  • A behavior is the observable, measurable physical act executed by an organism.
• Reinforcer Specificity and Dynamism:
  • Individual Specificity: Reinforcers are strictly specific to the individual; an item, event, or stimulus that functions as a potent reinforcer for one individual may serve as an aversive or neutral stimulus for another.
  • Preference Dynamism: Preferences are dynamic and may change over time due to external environmental conditions, biological states, or developmental progression, requiring systematic ongoing assessment.
  • The Matching Principle (Demand vs. Reinforcer Magnitude): Reinforcers must match the level of the demand.
• Ethical Mandates and Supervisory Safeguards for Punishment Procedures:
  • Intervention Tiering (Rule of Last Resort): Punishment must always be utilized as a last resort.
  • Formal Behavior Plan Requirement: Punishment procedures should only be utilized if explicitly written into the individual's formalized behavior plan.
  • Consent: Any implementation of a punishment protocol strictly requires prior written parent consent.
  • Supervision: Punishment must be carried out under the close supervision of the Board Certified Behavior Analyst (BCBA).

Motivating Operations and Schedules of Reinforcement

• Motivating Operations (MOs):
  • Definition: Variables that alter the reinforcing or punishing efficacy of a stimulus, object, or event.
  • Driving Factors: Environmental context, physiological deprivation, and biological satiation.
  • Establishing Operations (EO): An environmental or biological variable that makes a stimulus more desirable and more effective as a reinforcer; associated directly with states of deprivation, heightened want, or unfulfilled need; increases the momentary value of the reinforcer and evokes behaviors historically reinforced by that stimulus.
  • Abolishing Operations (AO): An environmental or biological variable that makes a stimulus less desirable and less effective as a reinforcer; associated with states of satiation where needs are already fulfilled or the stimulus is currently not wanted; decreases the momentary reinforcing effectiveness of the stimulus and abates behaviors historically reinforced by it.
• Foundational Schedules of Reinforcement:
  • Continuous Reinforcement (CRF): Reinforcement is delivered every single time the target behavior occurs; typically utilized during the initial acquisition of novel skills.
  • Intermittent Reinforcement: Reinforcement is given only some of the time that the behavior occurs; utilized for maintaining established behaviors and building resistance to extinction.
• Work-to-Break Ratio Systems:
  • Fixed Interval ($\text{FI}$): Reinforcement is delivered for the first correct response occurring after a set, exact period of time has elapsed; followed by the exact amount of time that must pass before reinforcement becomes available.
  • Formulaic Notation: $\text{FI } 2 = 2\,\text{minutes}$, indicating that an exact duration of $2\,\text{minutes}$ must elapse before an emitted response produces reinforcement.
  • Applied Example: Receiving a cup of coffee at an exact set period of every $2\,\text{hours}$.
  • Fixed Ratio ($\text{FR}$): Reinforcement is delivered following the completion of a set, exact number of responses; requires a rigid, non-varying count of behavioral outputs before the contingency is fulfilled.
  • Applied Example: Receiving a cookie for every set number of $5\,\text{burpees}$ completed.
  • Variable Interval ($\text{VI}$): Reinforcement is delivered for the first response emitted following a variable, unpredictable period of time; the interval requirement fluctuates around a specified mean temporal value.
  • Applied Example: Receiving an unpredictable goodnight "gorgeous" text across varying, non-fixed intervals of time.
  • Variable Ratio ($\text{VR}$): Reinforcement is delivered following a variable number of responses; the number of required responses changes unpredictably from one reinforcer delivery to the next, revolving around a designated average number of responses to generate high, steady response rates without post-reinforcement pauses.
• Non-Contingent Reinforcement (NCR):
  • A behavior reduction strategy where reinforcement is delivered completely independently of the individual's behavior.
  • Reinforcers are delivered on a time-based schedule (fixed or variable) regardless of whether the target behavior occurs.
  • Functions by disassociating the functional contingency between problem behavior and access to the reinforcing stimulus, reducing problem behavior via an abolishing operation effect.
• Token Economies:
  • An organized behavioral system where individuals receive tokens immediately after displaying a desirable target behavior.
  • Tokens function as immediate, generalized conditioned reinforcers contiguously paired with the emission of appropriate behavior, designed for subsequent exchange for primary or backup reinforcers.

Behavioral Measurement Procedures and Graphing Conventions

• Continuous Measurement Procedures:
  • Purpose: Records every single instance of a target behavior throughout the entire observation period.
  • Duration: A measurement of the total extent of time in which a behavior occurs; captures the temporal extent of a behavioral episode from its onset to its offset.
  • Frequency: The total number of occurrences of a behavior; also termed count or event recording.
  • Rate: A ratio of count per observation time, calculated as:     $\text{Rate} = \frac{\text{Frequency}}{\text{Duration}}$
  • Latency: A measurement of temporal locus; specifically, the elapsed time from the presentation or onset of a stimulus (such as a spoken cue or instructional prompt) to the initiation of a response.
  • Inter-Response Time (IRT): A measurement of temporal locus; defined as the elapsed time between two successive responses.
• Discontinuous Measurement Procedures:
  • Whole Interval Recording: The observer only records the behavior if it occurs continuously throughout the entire duration of the interval; underestimates behavior, as the behavior is scored as a non-occurrence if it stops for even a fraction of a second within the interval.
  • Partial Interval Recording: The observer records the behavior if it occurs at any point or for any amount of time during the observation interval; overestimates behavior, as a brief single instance triggers a positive score for the entire interval.
  • Momentary Time Sampling: The observer records whether the behavior is occurring specifically at the precise moment when an interval ends; allows the observer to engage in other activities or instruction without continuous visual monitoring until the timer expires.
  • Permanent Product Recording: A behavioral recording method in which durable products or physical outcomes of a behavior are assessed after the behavior has occurred; relies on tangible evidence left behind (e.g., completed worksheets, assembled items, damaged property) rather than direct real-time behavioral observation.
• Graphing Conventions in Behavior Analysis:
  • Function and Utility: Visual depictions of collected data that provide an organized visual representation of a child's behavior over time; enables behavior analysts to track progress, evaluate intervention efficacy, and make data-driven clinical decisions.
  • $\text{X-Axis}$: The horizontal axis; represents the passage of time, designated as the date or session number.
  • $\text{Y-Axis}$: The vertical axis; represents the quantitative dimension of the behavior, such as number of responses or frequency.
  • Phase Change Line: A vertical boundary line placed on a graph to indicate a significant change in the environment or treatment condition; marks distinct intervention conditions to allow comparison of behavioral data before and after the change.
  • Baseline: The measurement phase conducted before treatment or intervention is implemented; serves as the starting point or reference against which the effects of an intervention are judged.
  • Treatment: The phase implemented after baseline data collection, representing the introduction of an active treatment or intervention protocol.
  • Trend Line: Indicates the overall direction in which the data path is progressing (e.g., upward/increasing, downward/decreasing, or flat/zero trend).
  • Variability: Shows how consistent or inconsistent a behavior is across repeated measurements.
  • Low Variability: Data points are positioned close together, indicating consistent and steady performance.
  • High Variability: Data points are widely spread out, indicating erratic, unstable, or inconsistent behavior.
  • Scatter Plot: A data display that plots two variables together to identify temporal distributions, patterns, or correlations between environmental events and behavioral occurrences.

Behavior Intervention Plans, Environmental Contexts, and Antecedent Strategies

• Behavior Intervention Plan (BIP) Core Components:
  • Measurable and Observable Definitions: Must describe the target behavior strictly in terms that can be seen, heard, counted, or timed.
  • Non-Examples: May explicitly describe what the behavior does not look like to avoid subjective interpretation and false positives.
  • Counting Criteria: Specifies boundary criteria required to count multiple behavioral responses as separate occurrences versus a single ongoing behavioral episode.
  • Function of the Behavior: States the specific reason, motivation, or environmental cause maintaining the behavior.
  • Multiple Functions: A single topography of behavior may serve multiple functions simultaneously across different contexts.
  • Treatment Selection: The identified function dictates how clinicians address, intervene, and respond to behavioral data; interventions that do not match the behavioral function risk reinforcing the problem behavior.
• Environmental Contexts:
  • Antecedent Events: Immediate stimulus changes or occurrences that precede a behavior; state possible environmental events that may trigger or cause the target behavior to occur.
  • Setting Events: Broader contextual or physiological conditions that temporarily alter the value of consequences and make the target behavior significantly more likely to occur (e.g., being tired, being cold, or being present at a particular parent's home).
  • Precursor Behaviors: Sub-escalatory behaviors that reliably precede and may lead directly to the primary behavior targeted for reduction; serve as observable early warnings signaling staff to implement de-escalation protocols immediately.
• Antecedent Strategies Framework:
  • Definition: A specific intervention tool utilized proactively to prevent a target behavior or crisis event from occurring, implemented consistently throughout the entire session.
  • Premack Principle (Behavior Momentum): Often formulated as "First/Then" statements; contingently pairing a lower-probability task (non-preferred activity) before providing access to a high-probability behavior or reward (preferred activity).
• Preventative Antecedent Strategies Checklist:
  • Changes to the Physical Environment: Modifying furniture arrangement, lighting, seating, or proximity to distractions to eliminate potential triggers.
  • Increase Predictability: Establishing explicit structures and routines so expectations are clearly understood in advance.
  • Pre-Activity Preparation: Priming the learner before introducing complex tasks, instructional changes, or environmental transitions.
  • Visual Supports for Receptive Language: Employing visual aids, photographs, or icon boards to reinforce and facilitate receptive language comprehension.
  • Visual Schedules and Transition Warnings: Utilizing visual daily agendas and offering systematic warnings prior to ending an activity or transitioning to a new environment.
  • Provide Choices Proactively: Embedding multiple forced-choice opportunities throughout tasks (e.g., choosing materials, seating, or the sequence of activities) to promote learner autonomy before escape-maintained behaviors emerge.
  • Noncontingent Reinforcement (NCR): Delivering functional reinforcers on a fixed or variable time schedule completely independent of client behavior to reduce the motivating operation for problem behavior.
  • Social Narratives: Reading individualized narrative descriptions to prepare the individual for upcoming changes, novel experiences, or social expectations.
  • Modify or Accommodate Demands: Adjusting task difficulty, shortening required task lengths, or dividing large tasks into manageable instructional units.
  • Modify Presentation of Demands: Altering instructional tone, delivery speed, phrasing, or modality when delivering directions.
  • Pacing and Activity Interspersal: Altering instructional pacing, inserting regular work-break intervals, and embedding highly preferred activities within challenging routines.
  • Exercise Breaks: Providing structured physical activity or gross motor breaks to support regulation and alleviate behavioral tension.

Applied Behavior Analysis Principles, Rapport Building, and Discrete Trial Teaching

• Applied Behavior Analysis (ABA) Core Principles:
  • Systematic application of behavioral principles to improve socially significant behaviors.
  • Instructional and intervention targets are designed to create meaningful, functional changes in the client's everyday environment.
• Prerequisite Relationship Building:
  • Therapeutic Relationship: Prior to implementing any direct teaching skills or instructional trials, a strong therapeutic relationship must be established between the clinician and the client.
  • Happy, Relaxed, and Engaged (HRE): Denotes the optimal internal emotional and motivational state required for a client before presenting demands or instructional tasks, supporting learning receptivity and minimizing challenging behaviors.
  • Building Rapport: The deliberate process of creating a positive relationship with the client and earning their trust; forms the bedrock of client-therapist cooperation and instructional efficacy.
  • Pairing: The systematic procedure of pairing oneself with established, highly preferred reinforcers; conditions the therapist's presence as a conditioned reinforcer—becoming someone who is inherently fun, safe, and reinforcing to the client.
• Preparation Protocol Before Working with a Client:
  • Review the client's individualized cheat sheet thoroughly to remain informed on current programs, targets, and behavior protocols.
  • Ensure all needed instructional materials, stimuli, data-collection tools, and primary/secondary reinforcers are fully prepared and accessible prior to initiating sessions.
• Discrete Trial Training / Teaching (DTT):
  • Definition: A systematic method of teaching skills characterized by breaking down complex or harder target skills into simpler, discrete, and manageable steps.
  • Measurement: Progression and skill acquisition are quantitatively measured by collecting continuous trial-by-trial data.
  • Discriminative Stimulus ($\text{SD}$): An antecedent stimulus that signals the availability of reinforcement for a specific, corresponding behavior or response.
• Attending Protocol Prior to Delivering the $\text{SD}$:
  • Secure the child's active attention before presenting the discriminative stimulus.
  • Remove competing environmental distractions from the instructional setting.
  • Avoid repeatedly stating the child's name to gain attention, preventing the name from losing its instructional saliency or becoming paired with aversive task demands.
  • Incorporate playfulness and be silly to build natural engagement.
  • Utilize behavioral momentum (high-probability request sequences) to establish compliance before delivering the target $\text{SD}$.
  • Make funny noises to redirect visual and auditory attention to the clinician.
  • Engage in physical, playful motor actions such as "spaghetti arms" to establish clear visual orientation.
• Standardized Rules for Presenting the $\text{SD}$:
  • Neutral Voice: Maintain an even, calm, neutral vocal tone without emotional valence or inflections that distort stimulus clarity.
  • Simplified Language: Use concise, minimal, and direct wording suited to the client's receptive language capabilities.
  • Consistent $\text{SD}$: Deliver the exact predetermined prompt or verbal phrase consistently across trials without arbitrary variation.
  • Avoid Pairing Name with the $\text{SD}$: Refrain from attaching the client's name directly to the instruction (e.g., say "Touch red," not "[Name], touch red").
  • Refrain from Repeating the $\text{SD}$: Do not repeat the discriminative stimulus multiple times within a single trial.
  • Do Not Present During Problem Behavior: Cease presentation of the $\text{SD}$ if the client is actively engaged in problem behaviors to avoid reinforcing or pairing demands with maladaptive responses.
  • Latency Window: Implement a mandatory $3\,\text{second}$ pause following presentation to allow the client sufficient processing latency to respond independently before prompting.
• Augmentative and Alternative Communication (AAC):
  • A dedicated tablet communication device must be placed within direct, unhindered reach of the client.
• Replacement Behaviors:
  • Functional Equivalence: Replacement behaviors must serve the exact same function as the target maladaptive behavior (attention, escape, access to tangibles, automatic/sensory).
  • Teaching and Prompting: Clinicians must state and outline precise instructional strategies used to teach and prompt the alternative response.
  • Program Alignment: Replacement behaviors are frequently documented as Ensora goals within the client's individualized programming.
  • Proactive Precursor Prompting: Clinicians should prompt replacement behaviors at the earliest observable signs of precursor behaviors before escalation into severe problem behavior occurs.
  • Reinforcement Schedule: Replacement behaviors must always be reinforced immediately upon occurrence, unless specifically instructed otherwise by the BCBA.
• Response Strategies and Safety Safeguards:
  • Reactive Protocol: Clear, step-by-step strategies implemented when target problem behavior is actively occurring.
  • Withholding Functional Reinforcement: Response strategies must never reinforce the maintaining function of the behavior (implementing extinction principles).
  • Individualization: Every response strategy is uniquely tailored and individualized to the specific client's behavioral profile.
  • Safety Priority: All strategies must always be executed with fidelity to ensure physical and emotional safety.
  • Emergency Escalation: If safety is compromised or ever at risk, staff must immediately reach out for immediate assistance.
  • Restraint (Not Allowed): Defined as physically restricting or impeding the bodily movements of an individual for a duration of $3\,\text{seconds}$ or longer; strictly prohibited within standard instructional and behavioral programming.
  • Seclusion (Not Allowed): Defined as involuntarily removing the child from the setting and isolating him or her away from others; strictly prohibited across all behavioral clinical operations.

Error Correction Protocols and Prompting Frameworks

• Systematic Error Correction Overview:
  • Implemented systematically to increase learner motivation within educational and therapeutic environments.
  • Prevents mistakes during learning trials, directly creating a higher density of opportunities for positive reinforcement.
  • Reduces frustration and error perseveration, establishing a fluent and successful learning history.
• Errorless Learning Framework:
  • Core Definition: An instructional methodology engineered to minimize or entirely prevent a student from committing errors while acquiring a new skill or behavior; instruction is structured so that only correct responding occurs.
  • Response Blocking: A learner's incorrect response is actively blocked before or as it occurs.
  • Immediate Prompting: The correct response is immediately prompted following the block or stimulus presentation, ensuring immediate access to reinforcement.
  • Prompting Hierarchy: Typically relies on a most-to-least prompting hierarchy; prompts begin at the highest level of assistance necessary to guarantee success and are systematically faded over successive learning trials to transfer stimulus control.
  • Applied Example (Teaching a Child to Wave):
  • Step $1$: "Wave" instruction delivered $+$ Full Physical Prompt (e.g., hand-over-hand guidance to complete the wave).
  • Step $2$: "Wave" instruction delivered $+$ Partial Physical Prompt (e.g., guiding the learner at the wrist or forearm).
  • Step $3$: "Wave" instruction delivered $+$ Model Prompt (e.g., instructor models the waving action visually for the learner to imitate).
  • Step $4$: Independent Responding; the learner waves independently when greeted without requiring any supplemental prompts.
• Prompt Fading and Stimulus Fading Techniques:
  • Prompt Fading: The deliberate system utilized to move up and down the prompting scale based on client performance and mastery criteria; systematic prompt fading allows the learner to become independent and avoids prompt dependency.
  • Stimulus Fading: The process of gradually removing, altering, or diminishing an artificial prompt so that the learner continues to respond correctly, ultimately executing the behavior without assistance under the natural discriminative stimulus.
  • Dimensional Adjustment: Involves decreasing the intensity, salience, or magnitude of the prompt while intentionally staying within the exact same prompt level (e.g., gradually reducing the physical pressure of a touch or reducing the opacity of a visual cue).
• The Four-Step Error Correction Protocol:
  • Step $1$ (Model): The instructor immediately demonstrates the correct target response for the client to observe, providing an unambiguous reference of the desired behavioral topography.
  • Step $2$ (Prompt): The instructor presents the stimulus and uses an effective prompt from the prompting hierarchy to help the client evoke the correct response, ensuring active performance immediately following the modeled demonstration.
  • Step $3$ (Distract): The instructor distracts the client by presenting an intermediate, mastered, and simple task to clear working memory and ensure the subsequent test trial is not simply an immediate echoic or imitative copy of the prompt.
  • Distractor Examples: Directing the client to "touch nose", presenting a quick social interaction such as "hi $+$ wave", or presenting other simple, rapid, high-probability motor or verbal compliance tasks.
  • Step $4$ (Repeat): The instructor restates the original instruction or re-presents the initial task to evaluate whether the client can emit the target response independently or with reduced prompting following the distractor.

Preference Assessments, Extinction, and Verbal Operants

• Preference Assessment Procedures:
  • Purpose: Systematic methods that help determine potential reinforcers for a learner, critical for designing effective behavior intervention plans and skill acquisition programming.
  • Indirect Preference Assessments: Gathering preference data through informant report rather than direct observational interaction with stimuli.
  • Learner Self-Report: Asking learners directly about their preferences.
  • Interview and Checklist Assessments: Structured, formal checklists or interview formats completed by parents, teachers, caregivers, or independently by the client.
  • Single Stimulus Preference Assessment: Also referred to as a successive choice assessment; presents one item at a time to observe whether the client engages with it; if the client approaches and engages, it is identified as preferred; if not, the item is removed and the next item is presented; tracks the exact duration of engagement to gauge preference hierarchies.
  • Paired Choice / Forced Choice Assessment: Involves presenting two options simultaneously to the learner and recording which single item they choose.
  • Multiple Stimulus Without Replacement (MSWO): Multiple stimuli are presented in an array simultaneously; when an item is selected by the learner, it is removed from the array and not replaced for subsequent trials, ranking remaining items in a clear hierarchy.
  • Multiple Stimulus With Replacement (MSW): Multiple stimuli are presented in an array simultaneously; when an item is selected by the learner, it remains in the array or is replaced back into the array alongside the remaining options for subsequent trials.
  • Free Operant Assessment: Allowing the client unrestricted access to a variety of options and stimuli within a designated environment; the observer records total engagement duration for each item without presenting formal demands or removing chosen stimuli.
• High-Probability Request Sequence (Behavior Momentum):
  • Definition: An antecedent strategy used to increase the likelihood that a learner will follow through with a low-probability request.
  • Mechanism: The practitioner presents a rapid sequence of $2\text{ to }5$ easy, high-probability requests (tasks with a high compliance history) paired with immediate reinforcement, followed immediately by the delivery of the target low-probability request.
• Rules for Delivering Reinforcement:
  • Do not reinforce wrong behaviors; only reinforce the behavior targeted for increase.
  • Ignore problem behaviors; reinforcing unwanted behavior can strengthen maladaptive responses.
  • Use reinforcers the child likes, identified via preference assessments.
  • Systematically track progress over time using consistent data collection.
  • Be patient; behavior change takes time and consistent execution.
  • Concrete Reinforcement Example: Claps given for closing a book demonstrates a positive reinforcement paradigm where delivery of social praise (clapping) occurs contingent upon the completion of a targeted response (closing the book).
• Extinction Dynamics and Differential Reinforcement:
  • Extinction Burst: An immediate, temporary increase in the frequency, duration, or intensity of the targeted behavior immediately following the withdrawal of reinforcement.
  • Spontaneous Recovery: The sudden reappearance of a previously extinguished behavior after a period of time has elapsed without any recent reinforcement.
  • Differential Reinforcement of Alternative Behavior (DRA): Reinforcing a specific, desirable, and functionally equivalent alternative behavior while withholding reinforcement (extinction) for the problem behavior.
  • Differential Reinforcement of Other Behavior (DRO): Delivering reinforcement contingent upon the complete absence (omission) of the problem behavior throughout a specified interval of time.
  • Differential Reinforcement of Low Rates of Behavior (DRL): Delivering reinforcement only when the target behavior occurs at or below a predetermined rate or frequency threshold; used to reduce the frequency of behaviors that are acceptable in low quantities but problematic when excessive.
• Extinction Procedures and Contraindications:
  • Definition: Withholding reinforcement for a behavior that has been reinforced in the past, resulting in a reduction or elimination of that behavior over time.
  • Critical Safety Limitation: Extinction should not be used for behaviors that cause harm to oneself or others (e.g., severe self-injurious behaviors, severe physical aggression, or dangerous property destruction).
  • Sensory Function Extinction: Remove sensory input (e.g., masking, blocking, or neutralizing the sensory feedback that automatically reinforces the behavior).
  • Escape Function Extinction: Follow through with demand (not permitting the learner to avoid, delay, or escape the instructional request or task).
  • Attention Function Extinction: Planned ignoring (withholding all verbal reprimands, physical reactions, and social eye contact contingent on the behavior).
  • Tangible Function Extinction: Denied access (withholding access to the desired item, food, toy, or activity following the problem behavior).
• Functional Breaks, Token Economies, and Verbal Behavior Operants:
  • Token Boards: Deliver generalized conditioned reinforcers (tokens) contingent on desired behaviors, exchanged for backup reinforcers according to specific clinical policies.
  • Functional Breaks: The systematic implementation of breaks, whether used non-contingently, as functional communication training (manding for breaks), or within escape extinction procedures.
  • Verbal Behavior Operants: Classifies language into functional operants defined by their environmental controlling variables and consequences rather than grammatical structure.
  • Mand: A request for an object or action.
  • Tact (Labeling): Labeling an object, person, or action.
  • Echoic: Repeating a vocal behavior; characterized as "parroting".
  • Intraverbal: Social interchanges that involve explaining, discussing, or describing an item or situation that is not present or not currently happening.
