Behavioral therapy (ABA therapy) is the evidence-based psychological discipline that is widely used in children with various types of developmental disorders. Its technique is particularly relevant to the brain function of children with autistic spectrum disorder, which makes the learning process particularly effective in the event of this diagnosis. Behavioral therapy promotes the development of both cognitive skills and skills necessary for daily activities, replacing provocative behavior with a socially acceptable form of behavior. According to World Health Organization statistics, 50% of children with ASD who start ABA Therapy at an early stage will reach their relevant developmental level by the age 6.
