Differential Reinforcement, Extinction and Punishment
Candidates must distinguish DRA, DRI, DRO, DRL, FCT, extinction, punishment, and secondary effects.
How to study for the BACB RBT exam
Treat each question as an implementation decision: follow the written plan, collect objective data, protect dignity and confidentiality, and seek qualified supervision when needed.
Core concepts
Concept 1
Differential Reinforcement, Extinction and Punishment questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
DRA
Differential reinforcement of alternative behavior reinforces an appropriate replacement response.
DRI
Differential reinforcement of incompatible behavior reinforces a response that cannot occur with the target behavior.
DRO
Differential reinforcement of other behavior reinforces the absence of target behavior during a period.
DRL
Differential reinforcement of low rates reinforces reduced rates of behavior.
FCT
Functional communication training teaches communication that accesses the same function as problem behavior.
Extinction
Extinction withholds the maintaining reinforcer for a behavior.
Extinction Burst
An extinction burst is a temporary increase in behavior after extinction begins.
Punishment
Punishment decreases future behavior and requires strict ethical and supervisory safeguards.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
