What is a Contingency in Applied Behavior Analysis (ABA) Therapy?
A contingency in applied behavior analysis (ABA) therapy refers to the dependent relationship between a specific behavior and its consequence. Simply put, it describes:
- How specific behaviors are followed by certain outcomes
- How this can influence the likelihood of the behavior occurring or not occurring in the future.
Contingencies are fundamental to how ABA therapy helps children with autism learn new skills and reduce interfering behaviors. Contingencies make clear to the individual what actions will lead to which outcomes, increasing the likelihood of desired behaviors and decreasing undesired ones.
For example, in a classroom setting, a teacher might use the contingency: “If you finish your worksheet, you can have free time.”
Understanding and applying contingencies effectively is crucial in creating structured, predictable environments that support learning and development.
According to the CDC, structured behavioral interventions like those that use contingencies are evidence-based practices for children with autism.

Examples of Contingencies in ABA Therapy
Example 1: Positive Reinforcement Contingency
A child receives a sticker after saying “please” when asking for a toy. The consequence (sticker) is contingent on the desired behavior (using polite language). Over time, this increases the use of “please.”
Example 2: Negative Reinforcement Contingency
A behavior technician removes an aversive noise when a child puts on their headphones. The removal of the noise is contingent on the behavior of wearing headphones, encouraging the child to wear them again in the future.
Example 3: Response Cost Contingency
During a game, a child loses a token each time they interrupt another player. The consequence (loss of token) is contingent on the interrupting behavior, helping reduce interruptions.

Why are Contingencies Important in ABA?
Contingencies are the foundation of behavior change in ABA therapy. They:
- Clarify expectations by linking behavior to outcomes.
- Provide consistent consequences that strengthen or weaken behaviors.
- Help children with autism understand cause-and-effect relationships.
Behavior Technicians carefully design contingencies to ensure that reinforcement only occurs following appropriate behaviors. This creates an environment where children are motivated to engage in desired behaviors and learn new skills.

FAQs: What People Ask About Contingencies
What is a contingency in ABA?
A contingency is the relationship between a behavior and its consequence. It ensures that a specific outcome only occurs when a specific behavior happens (CDC).
Why are contingencies important in autism therapy?
Children with autism often benefit from clear, predictable structures. Contingencies help them understand what behaviors are expected and what outcomes they can earn or avoid.
What are examples of contingencies?
Examples include earning a break for completing work, losing a privilege for breaking a rule, or receiving praise for following directions.
How do behavior technicians set up contingencies?
They assess the child’s needs and preferences, identify target behaviors, and pair those behaviors with meaningful, consistent consequences.
Are contingencies always positive?
Not necessarily. Contingencies can involve positive reinforcement, negative reinforcement, punishment, or response cost—depending on the behavior goal and intervention plan.
Contingency Key Takeaways
- A contingency links a behavior to a consequence in a predictable way.
- It is a cornerstone of behavior modification in ABA therapy.
- Contingencies help children with autism learn skills, reduce interfering behaviors, and understand expectations.
Effective contingencies rely on consistency and meaningful consequences.
