Applied Behavior Analysis (ABA) has transformed from its early behaviorist roots into a versatile, evidence-based therapy supporting individuals with Autism Spectrum Disorder (ASD) and beyond. Evolving with feedback and ethical advancements, modern ABA emphasizes neurodiversity, individuality, and person-centered goals to improve communication, social skills, and quality of life. By valuing self-expression and autonomy, ABA fosters meaningful growth while celebrating unique identities, marking it as a cornerstone in behavioral therapy.
