Behavior Reduction

19% of the RBT exam · blueprint 3rd edition (2026)

Short answer

Domain D is 14 of 75 scored questions (19%). It covers identifying the common functions of behavior (attention, escape, access to tangibles, automatic), antecedent interventions such as NCR, high-probability request sequences and demand fading, differential reinforcement (DRO, DRA, DRI, DRL, FCT), extinction and its secondary effects (burst, resurgence), punishment procedures and their side effects, and crisis or emergency procedures.

Why it matters on this exam

Reduction questions are where candidates most often pick the "right-sounding" procedure for the wrong function. Every reduction procedure is chosen because of function, so start there.

Key concepts (tasks D.1–D.7)

Functions: social positive (attention, tangibles), social negative (escape/avoidance), automatic (sensory).
Antecedent interventions change conditions before behavior: noncontingent reinforcement (NCR), high-probability request sequence (behavioral momentum), demand fading, choice.
Differential reinforcement: DRO (other behavior/absence), DRA (alternative), DRI (incompatible), DRL (lower rate), FCT (teach a communicative replacement).
Extinction withholds the reinforcer that maintained the behavior — escape extinction looks very different from attention extinction. Expect an extinction burst, response variation, resurgence, and emotional responding.
Punishment (positive: add; negative: remove, e.g., time-out) can produce emotional responses and escape/avoidance; it is used only as written in the plan.
Crisis/emergency procedures: follow the written protocol, protect safety, document, and report to the supervisor.

Common mistakes

Using planned ignoring (attention extinction) for escape-maintained behavior — you would be reinforcing it.
Calling a token loss "extinction" (it is negative punishment).

Worked example

A learner screams when handed a worksheet; screaming reliably ends the task. Function: escape. Escape extinction means the demand stays in place; FCT teaches "break please"; a high-p sequence before the demand is an antecedent strategy. Removing attention would not address the function.

Original practice questions

Behavior ReductionDifficulty 2/5

A student throws materials during independent seatwork. Each time, the teacher removes the worksheet and the student sits quietly. The most likely function of throwing is:

AEscape from the task
BAutomatic reinforcement
CAccess to a tangible item
DAccess to attention

Show answer and rationale

Correct: A. The consequence that reliably follows the behavior is removal of the demand. Behavior that ends a task is maintained by negative reinforcement (escape). Identifying the function is task D.1 and drives the choice of intervention.

D — Attention is not what changes after the behavior; the demand is.
B — Automatic reinforcement would occur regardless of the social consequence.
C — No item is delivered after throwing.

Behavior ReductionDifficulty 3/5

An RBT begins escape extinction for task refusal exactly as the plan describes. During the first two sessions refusal becomes louder and more frequent before decreasing. What is this pattern called, and what should the RBT do?

AResurgence; stop the procedure and return to the previous plan until the supervisor reviews it
BExtinction burst; continue as written and report to the supervisor
CSpontaneous recovery; switch to attention extinction for the remainder of the session
DSatiation; change the reinforcer

Show answer and rationale

Correct: B. A temporary increase in frequency or intensity when reinforcement is first withheld is the extinction burst, a known secondary effect (task D.6). The RBT continues the procedure with fidelity and reports; stopping would reinforce the escalated behavior.

A — Resurgence is the return of a previously extinguished behavior when a newer behavior stops being reinforced.
C — Spontaneous recovery is reappearance after extinction, not an initial increase.
D — Satiation lowers behavior maintained by a reinforcer, not increases it.

Behavior ReductionDifficulty 3/5

A plan says: 'Deliver praise and a token every 2 minutes in which no hand-flapping occurs. If hand-flapping occurs, restart the interval.' This is:

ADRA
BDRI
CDRO
DDRL

Show answer and rationale

Correct: C. Reinforcement is delivered for the absence of the target behavior over an interval, and the interval resets on occurrence: differential reinforcement of other behavior (DRO). No specific alternative or incompatible response is required.

A — DRA reinforces a specific alternative behavior.
B — DRI reinforces a behavior that cannot occur at the same time as the target.
D — DRL reinforces a lower rate of the behavior, not its absence.
