Applied Behavior Analysis is a method of teaching based on the premise that speech, academics and life skills can be taught using scientific principles.  

ABA is based on the 20th-century work of B.F. Skinner. In 1938, Skinner published The Behavior of Organisms, which described the process of learning through the consequences of behavior. Later applications of his approach to education and socially significant behavior led to what we now call Applied Behavior Analysis.

ABA rewards, or reinforces, appropriate behaviors and responses because children are less likely to continue those behaviors that are not rewarded. Over time, reinforcement is reduced so that the child can learn without constant rewards.

Research shows that children with autism respond to ABA intervention (Lovaas, 1987; Sallows & Graupner, 2005). Skills are disassembled into their smallest components, so that the children learn to master simple skills, then build toward more complicated skills.

Skinner’s 1957 book, Verbal Behavior, focused on the functional analysis of verbal behavior, and led to significant research by Applied Behavior Analysts, including Dr. Jim Partington. This research can be found in the journal, The Analysis of Verbal Behavior, and serves as the foundation for teaching Verbal Behavior as part of an ABA program.

Applied Verbal Behavior is ABA with a focus on Verbal Behavior, and the application of ABA in teaching verbal behavior.

Early Intervention

There is no known cure for autism, and thus no “treatment” in the traditional medical sense, but intervention can and does elicit substantial improvement. A child with a diagnosis of Autism Spectrum Disorder (ASD) is delayed in their development of language and social interaction skills. Research indicates the need for, and the effectiveness of, early intensive behavioral intervention for children diagnosed with autism spectrum disorder.
