This document summarizes and analyzes the debates surrounding Applied Behavior Analysis (ABA) as a treatment for autism. It outlines how ABA emerged from behaviorism in the mid-20th century and was pioneered by Ole Ivar Lovaas, who used aversive techniques like beatings and shocks. While Lovaas' early work was controversial due to these methods, ABA became widely accepted after Lovaas published results in 1987 showing improvements. However, the neurodiversity movement now rejects ABA, arguing that autism is a natural difference rather than a disorder needing treatment, and that ABA can be psychologically harmful. The document examines both sides of the ongoing debates around ABA.
