ABA Differential Reinforcement Glossary: Essential Terms for RBTs and BCBAs

Differential reinforcement plays a vital role in ABA therapy. It reduces challenging behaviors while building new skills. For RBTs and BCBAs, this ABA differential reinforcement glossary covers key terms like DRA and DRO. These align with Task D-4 on the BACB RBT Task List (2nd Edition).

Here are 5 key takeaways from this ABA differential reinforcement glossary:

• Differential reinforcement pairs reinforcement of desired actions with extinction of undesired ones.
• DRA replaces problem behaviors with function-matched alternatives.
• DRI targets physically incompatible behaviors for easy limits.
• DRO rewards absence of the problem behavior over set intervals.
• Use DRL and DRH to shape low or high response rates precisely.

What Is Differential Reinforcement in ABA?

Differential reinforcement delivers reinforcement for desired behaviors. At the same time, it withholds reinforcement for undesired ones through extinction. This ethical method shapes behavior without punishment. It forms a core part of behavior intervention plans (BIPs), particularly in autism therapy.

The Behavior Analyst Certification Board (BACB) requires RBTs to implement these under BCBA supervision. The approach focuses on the function of problem behaviors, such as attention or escape. It promotes suitable alternatives. Common benefits include faster skill acquisition and reduced problem behaviors THE EFFECTS OF DIFFERENTIAL REINFORCEMENT OF ... - NIH. Check our guide to ABA reinforcement and punishment definitions for more on basics.

DRA: Differential Reinforcement of Alternative Behavior

In this ABA differential reinforcement glossary, Differential Reinforcement of Alternative Behavior (DRA) stands out. You reinforce a specific, appropriate behavior that serves the same function as the problem one. This replaces the undesired action. It does not demand incompatibility.

Picture a child who yells for a teacher's attention. That's an attention-seeking function. Reinforce hand-raising instead. Give praise or a token right after it happens.

Start by identifying the behavior's function through assessment. Next, teach the alternative with clear instruction. Reinforce continuously at first, then fade the schedule. DRA excels at skill-building, like better communication or compliance. Studies back its strength when paired with extinction PMC/NIH (2010).

DRI: Differential Reinforcement of Incompatible Behavior

Differential Reinforcement of Incompatible Behavior (DRI) reinforces a behavior that cannot happen at the same time as the problem one. This physical impossibility limits the undesired action naturally.

Think of a learner rocking aggressively during lessons. That might serve a self-stim function. Reinforce sitting still with hands on the desk. Rocking just can't occur then Magnet ABA.

First, pick an incompatible and appropriate behavior. Model it and use prompts. Reinforce every time it occurs. Ignore the problem behavior completely. DRI fits motor stereotypies well. It offers flexibility since it skips exact function matching.

DRO: Differential Reinforcement of Other Behavior

Differential Reinforcement of Other Behavior (DRO) delivers reinforcement if the problem behavior stays absent for a set time. Any other behavior counts. No specific alternative is required.

For a client who elopes from the table during homework—that's escape-motivated—set a timer. Reset it on elopement. Deliver a break after 5 minutes without it.

Begin with short intervals from baseline data. Use a timer or chart for tracking. Increase the time gradually as success builds. DRO works for low-rate behaviors. It avoids teaching specifics and appears on BACB RBT tests BACB RBT Task List (2020).

DRL and DRH: Low and High Rates

Differential Reinforcement of Low Rates (DRL) reinforces the target only below a set rate. This cuts excessive responding.

A talkative student interrupts class often. Reinforce if interjections drop under 3 per 10 minutes Vanderbilt IRIS.

Differential Reinforcement of High Rates (DRH) reinforces above a high criterion. It boosts skill fluency.

Reinforce math responses over 20 per minute for speed-building EBIP differential reinforcement.

First, collect baseline rates. Set criteria 20-50% above or below baseline. Thin the schedule as rates stabilize. These methods target rate goals, such as tics for DRL or academics for DRH. DRD (Diminishing Rates) shows up rarely. It's a DRL type for steadily lower rates without a standard BACB definition Differential Reinforcement of Diminishing Rates (DRD).

Implementing and Documenting Differential Reinforcement

RBTs follow BCBA plans for these procedures. Track data on interval successes or rates. Always document IOA and fidelity.

Visual timers help with DRO sessions. Pair reinforcement with antecedent strategies like prompts. Fade them step by step for independence.

In BIPs, adjust based on data trends. See our post on data-driven BIP revision triggers. Note the shift in RBT 3rd Edition starting January 2026. It emphasizes antecedents but keeps core principles BACB (2023).

Quick-Reference Table: ABA Differential Reinforcement Glossary

Procedure	Definition	Key Feature	Example
DRA	Reinforces alternative serving same function	Function-matched replacement	Hand-raising vs. yelling for attention
DRI	Reinforces physically incompatible behavior	Mutual exclusivity	Hands-folded vs. rocking
DRO	Reinforces absence in time interval	Any other behavior OK	No elopement for 5 minutes
DRL	Reinforces low-rate occurrences	Frequency criterion (low)	Fewer than 3 interruptions/10 min
DRH	Reinforces high-rate occurrences	Frequency criterion (high)	More than 20 responses/min
DRD	Reinforces progressively lower rates	Diminishing DRL variant	Research further for specifics

Exam Prep for RBTs and BCBAs

Differential reinforcement appears on RBT exams (14 behavior reduction questions) RBT Test Content Outline (3rd ed.) | BACB. Practice spotting differences: DRA matches functions; DRO skips alternatives.

Review BACB Task D-4 examples closely. Role-play each procedure in mock sessions. Quiz yourself on contrasts, like DRI versus DRO.

BCBAs should detail schedules in plans. These steps build mastery for certification.

Frequently Asked Questions

What are the main differences between DRA and DRO?

DRA targets a specific alternative that matches the problem's function. It teaches a replacement skill. DRO reinforces any behavior except the problem one over an interval. No specifics needed. DRA builds skills; DRO suppresses quickly Magnet ABA.

How does DRI differ from DRO in implementation?

DRI picks one incompatible behavior to reinforce. It relies on physical opposition. DRO times absence of the problem behavior. It allows various alternatives. Use DRI for motor issues and DRO for general reductions.

What are examples of behaviors for DRH?

DRH targets low rates like slow academic responses. Reinforce over 15 answers per minute. Or weak manding. It's key in fluency training, not reduction EBIP differential reinforcement.

How does differential reinforcement compare to punishment?

It relies on positive reinforcement ethically. This avoids side effects like aggression. Punishment suppresses but skips teaching. Differential reinforcement builds alternatives PMC/NIH (2010).

What are common challenges in differential reinforcement?

Watch for extinction bursts or tough schedule thinning. Thin gradually. Use high-value reinforcers. Monitor data closely.

Can differential reinforcement be used at home?

Yes. Parents can reinforce quiet requests over tantrums. Try short DRO intervals. Consult BCBAs for tailored plans Autism Parenting Magazine.
