Hundreds of academic studies have been done, and they have all resulted in the outcome that ABA is the most effective way to teach individuals with Autism Spectrum Disorder (ASD) as well as individuals with other developmental disabilities. Behavior analysis helps us to understand how behavior works, how behavior is affected by the environment, and how learning takes place. ABA therapy applies our understanding of how behavior works to real situations. The goal is to increase behaviors that are helpful and decrease behaviors that are harmful or affect learning. Applied Behavior Analysis (ABA) is an evident-based therapy that focuses on the science of learning and behavior.
