Applied Behavior Analysis (ABA) is an evidence-based approach widely used to support skill development and reduce challenging behaviors, particularly in children with autism. At its foundation are three core principles—often called the ABCs of ABA—that help therapists understand and shape behavior in meaningful ways.
-
Antecedent – What happens before a behavior occurs. This can be an instruction, an event, an environmental cue, or any trigger that sets the stage for a response.
-
Behavior – The observable action or response exhibited by the individual. Behaviors can be adaptive (such as using words to request) or challenging (such as yelling or withdrawing).
-
Consequence – What happens after the behavior. Consequences—like praise, access to a preferred item, or the removal of a demand—affect whether the behavior is more or less likely to occur in the future.
By carefully observing and adjusting these three elements, ABA therapists help children learn communication, social, self-care, and learning skills in a structured yet individualized manner.
At Happy Haven ABA, we build personalized therapy plans around these proven principles to support meaningful growth, independence, and positive outcomes for each child.
Frequently Asked Questions
What is the Antecedent in ABA?
An antecedent is any event, instruction, or environmental factor that occurs immediately before a behavior. Examples include giving a direction, presenting a learning material, or a change in routine. Identifying antecedents helps therapists understand what may trigger specific behaviors.
What does Behavior mean in ABA?
In ABA, behavior refers to any observable and measurable action. This can include verbal responses, physical actions, social interactions, or emotional expressions. The focus is on understanding the purpose or function of the behavior to teach more adaptive alternatives.
What is a Consequence in ABA?
A consequence is what follows a behavior and influences its future occurrence. Positive consequences (like praise or rewards) can strengthen desired behaviors, while other consequences can help reduce unsafe or disruptive actions. Consequences in ABA are planned and delivered consistently to support learning.
