The principles of ABA allow us to select target behaviors to increase (i.e. adaptive behaviors), or decrease (i.e. maladaptive behaviors), to maintain current levels of adaptive skills, to teach new skills, and to program for maintenance and generalization of skills that have been taught. These principles are grounded in years of scientific research, and replicated studies. The application of these principles to the teaching of individuals with ASD has been scientifically validated through applied research.
Early research by D. Baer, M. Wolf, T. Risley, and I. Lovaas, demonstrated that with early and intensive intervention, children with ASD can learn new skills and concepts, and generalize what they have learned across people, and environments (eg: new places and situations), and maintain skills over time.
ABA is a science that allows us to systematically implement basic principles of behavior (e.g: reinforcement, shaping, and chaining etc...) to help individuals learn how to learn. It is important to note that it is not a single specific instructional methodology. Sometimes "ABA" becomes confused with different types of instructional methods, such as "Lovaas-type ABA" or "Verbal Behavior ABA". There are many different instructional methodologies that are all based in the science of ABA. Some examples include: Discrete Trial Teaching, Verbal Behavior, Fluency Based Instruction, Natural Environment Teaching, and Video Modeling. Each of these instructional methods incorporates the basic principles of ABA into their instructional designs, however, each may place an emphasis on different aspects of learning.
