Applied Behavior Analysis


Applied Behavior Analysis

Applied Behavior Analysis (ABA) is defined as the science in which the principles of the analysis of behavior are applied systematically to improve socially significant behaviors. ABA is a scientific problem-solving approach aimed at improving an individual's ability to learn, function, participate, and enjoy the social world around them. Behavior Analysis is synonymous with Behavioral Psychology, Operant Learning, and the Experimental Analysis of Behavior.

Our Approach

The ABA team at NWBHS proudly provides high quality behavior analytic services to children, adolescents, and young adults diagnosed with Autism. Our ABA team uses only researched based behavior interventions including, but not limited to: Discrete Trial Training, Incidental Teaching, Natural Environment Teaching, Pivotal Response Training, and Verbal Behavior Analysis. We maintain a small, close-knit, collaborative ABA therapy team, which allows our therapists to remain with their clients throughout the entire intervention process with little to no employee turnover. Our practice employs only highly educated therapists, which exceeds industry and national standards. Each therapist is required to have their Registered Behavior Technician certificate and must maintain it.
