Applied Behaviour Analysis (ABA)

ABA is a type of therapy based on behaviorist principles of learning and motivation that aims to increase positive behaviors and reduce challenging ones using principles of reinforcement, punishment, extinction, and generalization. Rewards are given consistently to reinforce desired behaviours and make them more likely to continue. Undesired behaviours may be ignored (extinction) or have rewards removed (punishment).

Through systematic observation, evaluation, and intervention, applied behaviour analysis (ABA), a scientific approach within the discipline of behaviour analysis, aims to comprehend and change human behaviour. With the intention of fostering constructive behavior change and skill development, it focuses on recognizing the connection between a person's behavior and the environment.

Applied Behaviour Analysis (ABA)


Applied Behavior Analysis (ABA) is a comprehensive and evidence-based therapeutic approach rooted in the principles of behaviorism. Its origins can be traced to the early 20th century when psychologists such as Ivan Pavlov and John B. Watson were pioneering the study of behavior and its environmental influences. However, ABA as a distinct field of study and therapy gained prominence in the 1960s and 1970s. Psychologist B.F. Skinner, known for his work on operant conditioning, made significant contributions to the theoretical foundations of ABA, emphasizing the importance of observable and measurable behaviors.

The development of ABA as a therapeutic approach primarily focused on individuals with autism and developmental disorders. Psychologist Ivar Lovaas, in the 1960s, conducted groundbreaking research that demonstrated the effectiveness of ABA-based interventions in improving behaviors and skills among children with autism. This laid the foundation for early intervention programs, such as the Lovaas Model, which emphasized the principles of ABA to teach language, social, and adaptive skills.

Focus theme / core-concept

The core concept of Applied Behavior Analysis (ABA) centers on the systematic and data-driven examination of observable behavior and the environmental factors that influence it. ABA is rooted in the understanding that behavior is learned, and its focus lies in identifying functional relationships between behavior and the consequences that maintain or modify it. This approach emphasizes the use of evidence-based strategies, such as positive reinforcement and behavior modification techniques, to promote positive, adaptive behaviors, reduce problematic behaviors, and enhance the overall quality of life for individuals by systematically applying behavioral principles to various contexts, including education, therapy, and daily living.


Improved Behavior: ABA often leads to positive changes in behavior, making it a highly effective therapy for various populations.

Skill Development: Clients acquire essential life skills, which can improve their quality of life and independence.

Enhanced Quality of Life: ABA can significantly enhance an individual's overall well-being and functioning.

Promotion of Independence: Many individuals experience increased self-sufficiency and independence, particularly those with developmental disorders.

Better Social Interaction: ABA can lead to improved social relationships and communication skills, promoting a more fulfilling and connected life.


Behavior Modification: To change or improve specific behaviors by utilizing evidence-based strategies.

Skill Acquisition: To help individuals develop new skills and adaptive behaviors.

Reduction of Problem Behaviors: To decrease or eliminate problematic behaviors.

Enhanced Independence: To promote greater independence and self-sufficiency in daily life.

Effective Communication: To improve communication skills and social interactions, especially for individuals with autism or communication disorders.
