This document outlines the Seven Principles of Applied Behavior Analysis (ABA): 1) ABA grew out of experimental behavior analysis with animals but now focuses on real-life problems for individuals with developmental disabilities. 2) The goal of ABA is to improve behaviors through manipulating variables rather than just examining their effects. 3) ABA prioritizes social relevance and improving behaviors over theoretical importance. It assesses how important the target behavior is to the individual. 4) ABA uses measurable behaviors as targets rather than subjective interpretations, relying on observer reliability.
