Here at David Gregory School, we continually contribute to the body of research in autism and developmental disabilities. Our research focuses on verbal behavior, classroom applications of behavior analysis, parent training, and teacher training. These research efforts are led by Dr. Gladys Williams, an internationally renowned ABA Specialist who earned her doctoral degree in Special Education and Behavior Analysis from Columbia University in New York City.

Research articles from our program have been published in the journals of Applied Behavior Analysis, American Journal on Mental Retardation, Teaching Exceptional Children, Behavioral Residential Treatment, and Psicothema (the behavioral journal in Spain). Papers and posters have been presented by Dr. Williams around the world at symposia and the yearly conferences organized by the Association of Behavior Analysis, since 1985.

Currently we are utilizing research strategies and techniques to facilitate language emergence in non-verbal children.

The following research from David Gregory School has been used in educating and training teachers and psychologists around the world to facilitate learning and implement individualized ABA programs for children with developmental delays and autism.
