A conditioned reinforcer, also called a secondary reinforcer, is a neutral object, word, or symbol (“stimulus”) that gains the ability to motivate behavior after being repeatedly paired with an unconditioned (primary) reinforcer. Common examples include tokens, praise, and money.

Because primary reinforcers — like food or water — aren’t always practical to use every time a child demonstrates a desired behavior, ABA therapists establish conditioned reinforcers that can be delivered immediately and consistently to strengthen positive behaviors.

Reinforcement is a core strategy in Applied Behavior Analysis (ABA) because it directly drives learning and behavior change. Whether you’re preparing for the BCBA or RBT exam or brushing up on the basics, this guide will help you understand how conditioned reinforcers are established, used, and applied in everyday ABA practice.

What Makes a Reinforcer “Conditioned”?

Conditioned reinforcers must be established as motivators through learned experience since they are not innate. This is typically done by pairing primary and secondary reinforcers:

Conditioned vs. unconditioned reinforcers

The key difference between conditioned and unconditioned reinforcers is that the former is taught while the latter is biological.

For example, a delicious snack is an unconditioned motivator because it satisfies a basic biological need. In therapy sessions, a child may earn a token (conditioned reinforcer) after completing a task and later exchange it for a preferred snack (unconditioned reinforcer).

Conditioned (secondary) Unconditioned (primary)
How it gains value Learned through pairing with an existing reinforcer Innate; satisfies a basic biological need
Requires learning history Yes — varies from child to child No — effective without prior experience
Examples Tokens, praise, money, stickers Food, water, sleep

The role of pairing and learning history

ABA therapists establish conditioned reinforcers by repeatedly pairing them with a primary or other already established reinforcer. Over time, these repeated pairings teach the child that the conditioned reinforcer leads to something they value.[1]

A child’s learning history, or previous experiences with reinforcement, influences which conditioned reinforcers are most motivating. Because every child has a different learning history, conditioned reinforcers vary from child to child.

Common Examples of Conditioned Reinforcers

Conditioned reinforcers are found throughout everyday life and in therapy. Below are some common examples:

Generalized reinforcers

Unlike regular conditioned reinforcers that are associated with a single reinforcer, generalized conditioned reinforcers are associated with many different backup reinforcers — such as a toy or extra playtime. Because they can be exchanged for a variety of rewarding outcomes, they tend to remain motivating across different situations. Below are some examples:

Tokens and token economies

In ABA therapy, a token economy is a reward system that uses symbolic tokens — like stickers or plastic chips — that can be traded for backup reinforcers.

The benefit of using tokens instead of delivering the actual reward after every desired behavior is that they provide immediate reinforcement and can be delivered after every correct response. This allows therapists to reinforce positive behaviors more frequently while children work toward larger rewards.

Praise, money, and generalized reinforcers

Money is the classic example of a generalized conditioned reinforcer because it can be exchanged for countless goods and experiences. Similarly, praise is a generalized reinforcer because it’s consistently associated with other rewarding experiences, such as hugs, high-fives, celebrations, and other forms of positive social interaction.

How Conditioned Reinforcers Are Established

Conditioned reinforcers are established through pairing, a process in which a neutral stimulus is repeatedly paired with a primary reinforcer or an already established conditioned reinforcer. Over time, the neutral stimulus acquires reinforcing value and can motivate behavior on its own.

Stimulus pairing vs. response-stimulus pairing

ABA therapists commonly use two pairing techniques to establish conditioned reinforcers: stimulus pairing and response–stimulus pairing.

Stimulus pairing involves repeatedly presenting a neutral stimulus alongside an unconditioned or already established conditioned reinforcer, regardless of the child’s behavior. For example, a therapist may repeatedly pair praise with a favorite snack until praise alone becomes reinforcing.

Response–stimulus pairing involves delivering a conditioned reinforcer only after the child demonstrates a desired behavior. For example, a child may earn a sticker on their sticker card every time they correctly request help.

Avoiding satiation, fading dependency

When using conditioned reinforcers, ABA therapists regularly monitor progress to maintain their reinforcing value and gradually promote independence.

If a reinforcer is used too often, it can become less motivating — this is called satiation. To prevent satiation, therapists rotate conditioned and backup reinforcers as a child’s interests and motivations change.

As children master new skills, therapists gradually fade conditioned reinforcers so they become less reliant on external rewards. The goal is for children to use their skills independently because the behavior naturally leads to positive outcomes, such as getting what they need or enjoying social interactions.

Why This Matters for the BCBA and RBT Exams

Conditioned reinforcement is a key concept for BCBA and RBT candidates because reinforcement is one of the core strategies ABA uses to teach new skills and strengthen positive behaviors.

Candidates need to understand not only what conditioned reinforcers are, but how to establish and use them effectively in practice and exam scenarios.

Where it falls in the BACB task list

In the BCBA Test Content Outline (6th ed.), conditioned reinforcement appears in two key areas. Task B.7 covers identifying and distinguishing between unconditioned, conditioned, and generalized reinforcers, while Task G.4 covers procedures for establishing and using conditioned reinforcers, including token economies.[2]

How it shows up in exam questions

Because BACB exams use multiple-choice questions, you may need to apply the concept rather than simply recall its definition. For example, a question may ask you to:

  • Identify a conditioned reinforcer from a scenario.
  • Distinguish conditioned, unconditioned, and generalized reinforcers.
  • Recognize how a token economy establishes and uses conditioned reinforcement.
  • Determine an appropriate way to establish or maintain a conditioned reinforcer.

Putting Conditioned Reinforcers into Practice

As an RBT or BCBA, you play a pivotal role in shaping positive behaviors and skill development in children with autism. Conditioned reinforcers are just one of many strategies you’ll pull from to help motivate new skills, reinforce progress consistently, and encourage children to become more independent.

At United Care ABA (UCABA), positive reinforcement strategies shape how we help children work toward meaningful goals. These strategies are so pivotal that we support parents to incorporate them into everyday routines at home.

For BCBAs and RBTs, knowing how to establish and use conditioned reinforcers is a skill you’ll put into practice every day. Learn more about UCABA, explore our locations, or take the next step and join the UCABA team to grow your ABA career.


Frequently Asked Questions

What is an example of a conditioned reinforcer?

Tokens, praise, and money are the most common examples. Each one starts out neutral and only becomes reinforcing after repeated pairing with something the learner already values.

What are conditioned reinforcers in ABA?

They’re stimuli that gain reinforcing power through a learning history, usually by being paired with a primary reinforcer like food or a preferred activity. They’re also called secondary reinforcers.

What is a generalized conditioned reinforcer?

It’s a conditioned reinforcer that’s been paired with many different reinforcers rather than just one, which makes it less likely to lose effectiveness. Money is the textbook example.

Is praise a conditioned or primary reinforcer?

Praise is conditioned. It has no innate value on its own and becomes reinforcing only after it’s been consistently paired with positive outcomes for that individual.

Which BACB task list item covers conditioned reinforcers?

The 6th Edition BCBA Test Content Outline addresses this in B.7, identifying and distinguishing among unconditioned, conditioned, and generalized reinforcers, and again in G.4, establishing and using conditioned reinforcers like token economies.
