A scientific approach to understanding and modifying behavior through systematic observation, measurement, and manipulation of environmental variables.

Applied Behavior Analysis (ABA)

Applied Behavior Analysis is a systematic approach to understanding and changing behavior based on the principles of behaviorism and learning theory. It focuses on the relationship between environmental events and behavior, using data-driven methods to promote meaningful behavioral change.

Core Principles

ABC Model

The fundamental framework of ABA consists of:

Antecedent: Events that occur before a behavior
Behavior: The observable action or response
Consequence: What follows the behavior

This model helps practitioners understand the functional analysis factors that maintain specific behaviors.

Key Components

Applications
