RBT Exam Study Guide: Behavior Reduction


Overview

Behavior reduction is a core competency for Registered Behavior Technicians (RBTs), encompassing a range of ethical, evidence-based strategies to decrease problem behaviors. Effective behavior reduction requires identifying the function of a behavior, selecting the least restrictive appropriate intervention, and implementing procedures consistently under BCBA supervision. This guide covers extinction, punishment procedures, antecedent interventions, differential reinforcement, crisis procedures, and foundational concepts.

Foundational Concepts


Understanding Behavioral Function

Before any behavior reduction strategy is selected, the function of the behavior must be identified. Function refers to why a behavior occurs — the reinforcing consequence that maintains it.


The Four Functions of Behavior (SEAT):

  • • Sensory/Automatic — behavior provides internal reinforcement (e.g., rocking, hand-flapping)
  • • Escape/Avoidance — behavior removes an aversive stimulus (e.g., tantrums to avoid tasks)
  • • Attention — behavior produces social attention (e.g., acting out when ignored)
  • • Tangibles — behavior produces access to items or activities (e.g., grabbing toys)

    • > Why it matters: Interventions must be matched to the function. A function-mismatched intervention (e.g., giving attention to escape-maintained behavior) can inadvertently reinforce the problem behavior and make it worse.


    ---


    The Behavior Intervention Plan (BIP)

    A Behavior Intervention Plan (BIP) is a written document developed by a BCBA that guides the RBT's work with problem behaviors.


    A BIP typically includes:

  • • Operational definition of target behaviors
  • • Hypothesized function of each behavior
  • • Antecedent modifications
  • • Replacement/alternative behaviors to teach
  • • Consequence strategies (reinforcement and/or punishment)
  • • Crisis and safety procedures
  • • Data collection methods

    • > RBT's Role: Implement the BIP as written. Do not modify procedures independently. If a new dangerous behavior emerges that isn't addressed, ensure safety, document accurately, and report to the supervising BCBA immediately.


    ---


    The Least Restrictive Intervention Principle

    Behavior reduction procedures must follow a hierarchy from least to most restrictive:


    ```

    1. Antecedent modifications (prevent the behavior)

    2. Differential reinforcement (reinforce alternatives)

    3. Extinction (withhold the maintaining reinforcer)

    4. Punishment procedures (only after above have failed)

    ```


    Key Terms:

  • • Least restrictive intervention — using the most positive, least intrusive strategy that is effective
  • • Behavior Intervention Plan (BIP) — the written plan guiding all behavior reduction efforts
  • • Function — the purpose or reinforcer maintaining a problem behavior

    • > Watch Out For: Punishment procedures are not a first resort. The exam will test whether you know that reinforcement-based strategies must be tried and documented as ineffective before punishment is implemented.


    ---


    Extinction


    What Is Extinction?

    Extinction is the discontinuation of the reinforcer that previously maintained a behavior, resulting in a gradual decrease in that behavior over time.


  • • Extinction does not mean ignoring all behavior — it means withholding the specific reinforcer that maintains the behavior.
  • • The type of extinction used must match the function of the behavior.

    • Extinction by Function:


    | Function | Extinction Procedure | What Is Withheld |

    |---|---|---|

    | Attention | Planned ignoring | Attention |

    | Escape/Avoidance | Escape extinction | Removal of the demand |

    | Tangibles | Withhold item/activity | Access to the tangible |

    | Automatic/Sensory | Sensory extinction | Sensory input (harder to implement) |


    > Example: If a child tantrums to escape demands → use escape extinction (continue presenting the demand, do not allow escape as a result of the tantrum).


    ---


    Extinction Burst

    An extinction burst is a temporary increase in the frequency, intensity, or duration of a behavior when reinforcement is first withheld.


  • • This is a normal, expected part of the extinction process.
  • • The burst typically subsides if extinction is applied consistently.
  • • An extinction burst is not a sign that extinction is failing — it means the procedure is being applied correctly.

    • ---


    Spontaneous Recovery

    Spontaneous recovery is the reappearance of a previously extinguished behavior after a period of time has passed without the behavior occurring.


  • • This is also a normal, expected phenomenon.
  • • If the behavior reappears, continue implementing extinction consistently — it will extinguish again, typically faster than the first time.

    • ---


    Consistency in Extinction

    Inconsistent extinction creates an intermittent reinforcement schedule, which:

  • • Strengthens the behavior
  • • Makes it more resistant to future reduction
  • • Can undo progress already made

    • Key Terms:

  • • Extinction — withholding the maintaining reinforcer
  • • Extinction burst — temporary increase in behavior at the start of extinction
  • • Spontaneous recovery — reappearance of extinguished behavior after a time lapse
  • • Escape extinction — continuing the demand to withhold escape reinforcement
  • • Intermittent reinforcement — unpredictable delivery of reinforcement, increases resistance to extinction

    • > Watch Out For:

    > - Don't confuse an extinction burst with the procedure failing — it's expected.

    > - Don't confuse extinction with punishment — extinction removes the reinforcer; punishment adds or removes a stimulus to decrease behavior.

    > - Spontaneous recovery ≠ the behavior is "back for good" — keep implementing extinction.

    Antecedent Interventions


    Overview

    Antecedent interventions prevent problem behavior by modifying conditions before the behavior occurs. They are among the least restrictive and most ethical first-line strategies.


    ---


    Motivating Operations (MOs)

    A Motivating Operation (MO) is an environmental variable that temporarily:

    1. Alters the value of a reinforcer or punisher

    2. Alters the frequency of behaviors associated with that reinforcer


    Two Types:

  • • Establishing Operation (EO) — increases the value of a reinforcer (e.g., food deprivation makes food more reinforcing)
  • • Abolishing Operation (AO) — decreases the value of a reinforcer (e.g., eating a large meal makes food less reinforcing)

    • > In behavior reduction: If you can identify and modify the MO, you can reduce the problem behavior before it starts. For example, ensuring a child has had enough attention before a task can reduce attention-seeking behavior during the task.


    ---


    Non-Contingent Reinforcement (NCR)

    NCR delivers reinforcement on a fixed-time (FT) or variable-time (VT) schedule, independent of the individual's behavior.


  • • How it reduces behavior: By providing the reinforcer freely, the MO for the problem behavior is abolished (the need is already met).
  • • Best used when the function of the behavior is known.
  • • Over time, the schedule is thinned to maintain behavior reduction with less frequent delivery.

    • > Example: If a child seeks attention by hitting, deliver attention every 3 minutes regardless of behavior → the motivation to hit for attention decreases.


    ---


    High-Probability Request Sequence (High-p Sequence)

    The high-p sequence involves presenting several easy, high-compliance requests before presenting a low-probability (challenging) request.


  • • Goal: Build behavioral momentum so the client is more likely to comply with the difficult request.
  • • Reduces: Non-compliance, escape-maintained problem behaviors.

    • > Example: Before asking a child to complete a difficult math worksheet (low-p), ask them to "give me five," "stand up," and "touch your nose" (high-p requests they reliably comply with).


    ---


    Stimulus Control Transfer

    Stimulus control transfer involves changing the antecedent stimuli that occasion problem behavior so that appropriate behaviors are evoked instead.


  • • Alters the triggering conditions for problem behavior.
  • • Can involve changing the environment, the person giving instructions, or the context of the activity.

    • ---


    Stimulus Satiation

    Stimulus satiation involves providing free and continuous access to a reinforcer until it loses its reinforcing value.


  • • This abolishes the MO, reducing the problem behavior the reinforcer was maintaining.
  • • Best used with tangible-function behaviors.

    • > Example: Providing unlimited access to a preferred toy before a session → the child is less motivated to engage in problem behavior to obtain that toy.


    Key Terms:

  • • Motivating Operation (MO) — alters reinforcer value and related behavior frequency
  • • Establishing Operation (EO) — increases reinforcer value
  • • Abolishing Operation (AO) — decreases reinforcer value
  • • NCR — reinforcement delivered on time schedule, independent of behavior
  • • High-p sequence — easy requests before hard requests to build compliance
  • • Stimulus satiation — free access to a reinforcer until it loses value

    • > Watch Out For:

    > - NCR is not the same as ignoring (extinction) — NCR delivers reinforcement; extinction withholds it.

    > - The high-p sequence works by building behavioral momentum, not by tricking the client.


    ---


    Differential Reinforcement


    Overview

    Differential Reinforcement (DR) procedures reinforce a desired behavior while withholding reinforcement for the problem behavior. They are positive, function-based, and among the most recommended behavior reduction strategies.


    ---


    DRO — Differential Reinforcement of Other Behavior

    DRO delivers reinforcement when the target problem behavior has not occurred during a specified time interval.


  • • Reinforces the absence of the behavior
  • • Does not specify what behavior should occur — just that the problem behavior does not occur
  • • Uses an interval-based system (e.g., "No hitting for 5 minutes → reinforcement")

    • > Example: Deliver a token every 5 minutes that the child does not engage in self-injurious behavior.


    ---


    DRI — Differential Reinforcement of Incompatible Behavior

    DRI reinforces a behavior that is physically incompatible with the problem behavior.


  • • Both behaviors cannot occur simultaneously
  • • Reinforcement is withheld for the problem behavior

    • > Example: Reinforce "hands in lap" (incompatible with hitting) to reduce hitting. The child cannot have hands in lap AND be hitting at the same time.


    ---


    DRA — Differential Reinforcement of Alternative Behavior

    DRA reinforces a specific alternative behavior that replaces the problem behavior while withholding reinforcement for the problem behavior.


  • • The alternative behavior does not need to be physically incompatible
  • • The alternative behavior should ideally serve the same function as the problem behavior

    • > Example: Reinforce raising a hand to get attention (alternative behavior) rather than calling out (problem behavior).


    ---


    FCT — Functional Communication Training

    FCT is a specialized form of DRA in which the individual is taught to communicate their needs using an appropriate response (verbal request, sign, AAC device) that replaces the problem behavior.


  • • The communication response must serve the same function as the problem behavior
  • • FCT is highly effective because it addresses the underlying function directly

    • > Example: Teach a child who throws items to access a break to instead hand a "break card" to the teacher → same function (escape), appropriate topography.


    ---


    DRL — Differential Reinforcement of Low Rates

    DRL delivers reinforcement when a behavior occurs at or below a predetermined low-rate criterion.


  • • Used when the goal is to reduce but not eliminate a behavior
  • • The behavior is acceptable at low rates but problematic at high rates

    • > Example: Reinforce a student for raising their hand 3 or fewer times during a 30-minute class period (reduces excessive hand-raising without eliminating participation).


    ---


    Comparing DR Procedures


    | Procedure | What Is Reinforced | Goal | Notes |

    |---|---|---|---|

    | DRO | Absence of problem behavior | Eliminate | Interval-based |

    | DRI | Incompatible behavior | Eliminate | Behaviors cannot co-occur |

    | DRA | Specific alternative behavior | Eliminate/Replace | FCT is a type of DRA |

    | DRL | Behavior at/below low rate | Reduce (not eliminate) | Behavior is OK at low levels |

    | FCT | Functional communication | Eliminate/Replace | Specific form of DRA |


    Key Terms:

  • • DRO — reinforcement for the absence of behavior during an interval
  • • DRI — reinforcement for an incompatible behavior
  • • DRA — reinforcement for an alternative behavior
  • • DRL — reinforcement for behavior at low rates
  • • FCT — teaching communication to replace problem behavior (type of DRA)

    • > Watch Out For:

    > - DRI vs. DRA: In DRI, the behaviors are physically incompatible. In DRA, they are functionally alternative but can physically co-occur.

    > - FCT is a type of DRA — know this distinction.

    > - DRL does not eliminate behavior — it allows it at low rates. Use when zero rates are not the goal.

    > - For DRO, if the problem behavior occurs during the interval, the interval resets or reinforcement is withheld for that interval.

    Punishment Procedures


    Critical Ethical Note

    Punishment procedures are only used when:

    1. Reinforcement-based and antecedent strategies have been tried and found ineffective

    2. The procedure has been approved by the supervising BCBA and treatment team

    3. Appropriate consent has been obtained

    4. The least restrictive punishment option is used


    > The RBT does not design punishment procedures — they are developed by the BCBA. The RBT's role is to implement them as written in the BIP.


    ---


    Positive Punishment

    Positive punishment = Addition of a stimulus following a behavior → Decreases future probability of that behavior.


  • • The "positive" refers to adding something (not that it is pleasant)
  • • The added stimulus is aversive to the individual

    • > Example: Contingent exercise (requiring push-ups after problem behavior), verbal reprimands.


    ---


    Negative Punishment

    Negative punishment = Removal of a stimulus following a behavior → Decreases future probability of that behavior.


  • • The "negative" refers to removing something
  • • The removed stimulus is something the individual values

    • Two Common Forms of Negative Punishment:


    #### Response Cost

    Response cost = Removal of a specified amount of a reinforcer contingent on a target behavior.


    > Example: A student loses 2 tokens from their token economy for each instance of calling out in class.


    #### Time-Out from Positive Reinforcement

    Time-out = Removal of access to reinforcement for a brief, defined period contingent on problem behavior.


  • • Must be a brief, defined period (e.g., 2–5 minutes)
  • • Time-out only works if the current environment is reinforcing (you cannot remove access to reinforcement if there is no reinforcement to remove)
  • • Can be exclusionary (removed from the environment) or non-exclusionary (remains in environment but access to reinforcement is blocked)

    • > Example: A child who throws toys is moved to a chair away from the play area for 3 minutes.

    Positive vs. Negative Punishment Summary


    | | Positive Punishment | Negative Punishment |

    |---|---|---|

    | Operation | ADD a stimulus | REMOVE a stimulus |

    | Effect | Decrease in behavior | Decrease in behavior |

    | Examples | Reprimands, contingent exercise | Response cost, time-out |


    Key Terms:

  • • Positive punishment — add an aversive stimulus → behavior decreases
  • • Negative punishment — remove a valued stimulus → behavior decreases
  • • Response cost — specific amount of reinforcer removed contingent on behavior
  • • Time-out — brief removal of access to all reinforcement

    • > Watch Out For:

    > - "Positive" and "negative" refer to adding or removing a stimulus — NOT whether the procedure is good or bad.

    > - Punishment ≠ extinction. Punishment involves
