Applied Behavior Analysis (ABA) is a therapeutic approach rooted in the science of learning and behavior. It focuses on understanding how behavior works, how it is affected by the environment, and how learning takes place. It is most commonly associated with supporting individuals, particularly children, on the autism spectrum or with other developmental disorders.

ABA relies on a framework called the "A-B-Cs" to analyze and modify behavior:
  Antecedent: What occurs immediately before a behavior (e.g., a verbal request from a teacher or a sound in the environment).
  Behavior: The individual’s response or action.
  Consequence: What happens immediately after the behavior (e.g., a reward for a positive action or a lack of response for an undesired one).

The core philosophy is that behavior followed by positive reinforcement is more likely to be repeated, while behavior that does not receive reinforcement is less likely to recur.

ABA is widely recognized as an evidence-based practice by major organizations such as the American Psychological Association. Decades of research have supported its effectiveness in improving outcomes related to socialization and communication.

However, the field has evolved significantly. While early versions of ABA in the mid-20th century were sometimes criticized for being rigid or using punitive measures, modern "safe" ABA is:

• Strengths-based: Focused on building existing skills and respecting neurodiversity.

• Play-based: Designed to feel natural and engaging rather than strictly clinical.

• Focused on Quality of Life: Emphasizing skills that are meaningful and functional for the individual's daily life.
