What is a Response in Applied Behavior Analysis (ABA) Therapy?
In applied behavior analysis (ABA), a response refers to a specific instance of behavior that occurs following a particular stimulus. It is the observable reaction a person has to an environmental event or instruction. Responses can be verbal or physical, simple or complex, and are essential to how ABA professionals assess, teach, and reinforce behaviors.
Responses are often measured by:
- Topography (what the behavior looks like)
- Latency (how long it takes to start the behavior after a cue)
- Duration (how long the behavior lasts)
- Frequency (how often the behavior occurs)
In ABA programs, Behavior Analysts define target responses clearly to ensure consistency and accuracy in data collection. For example, a response to the instruction “Give me high five” might be defined as the child raising their hand and making palm-to-palm contact within 5 seconds.
Understanding and shaping responses is a core component of ABA therapy and plays a critical role in supporting children with autism.
According to the BACB Task List (5th ed.), identifying and defining behavior and responses is a fundamental skill required of behavior analysts.

Examples of Response in ABA Therapy
Verbal Response to a Question
A behavior technician asks, “What color is the apple?” The child answers, “Red.” This is a correct verbal response, which can be reinforced with praise or a preferred activity.
A Response to a Prompt
The behavior technician presents a visual cue of a toothbrush and says, “Show me how to brush.” The child mimics brushing teeth. This modeled motor response is part of teaching self-care skills.
Response Chain
During a hand-washing routine, the child turns on the water, applies soap, rubs hands, and rinses. Each step is a separate response within a behavior chain. Behavior technicians may teach or reinforce each response individually before chaining them together.

FAQs: What People Ask About Response in ABA
What is a response in ABA?
In ABA, a response is a specific behavior that occurs following a stimulus or instruction. It is what the individual does in reaction to a cue or event.
How is a response measured in ABA?
Responses are measured using dimensions like frequency, latency, duration, and accuracy. This helps determine progress and effectiveness of interventions.
What is the difference between stimulus and response?
A stimulus is an event or cue that precedes behavior, while the response is the action that follows. For example, a teacher’s instruction is the stimulus; the student’s behavior is the response.
Why is identifying a response important in ABA?
Clearly defining and observing responses ensures that ABA programs are consistent, data-driven, and goal-oriented. It also allows behavior technicians to reinforce appropriate behaviors and reduce interfering or interrupting behaviors.
Can a response be a chain of behaviors?
Yes. Some responses, like tying shoes or brushing teeth, involve multiple actions performed in a sequence. These are known as response chains and are often taught step-by-step in ABA.
Response in ABA Key Takeaways
- A response in ABA is any observable behavior that follows a stimulus.
- Responses can be verbal, physical, simple, or part of a behavior chain.
- Measuring responses helps Behavior Analysts track progress and shape behavior.
- Responses are critical in teaching new skills and reducing interfering behaviors.
- Clear response definitions support consistency in ABA program delivery.
