“Applied Behavior Analysis (ABA) is the design, implementation, and evaluation of environmental modifications to produce socially significant improvements in behavior. ABA includes the use of direct observation, measurement, and functional analysis of the relations between environment and behavior. Based on the findings of descriptive and functional analysis, ABA uses antecedent stimuli and consequences to produce practical change.

ABA is based on sound scientific principles and has a solid research foundation that proves its effectiveness. ABA is based on the belief that an individual’s behavior is determined by past and current environmental events in conjunction with organic variables, including genetics. Therefore, ABA focuses on explaining behavior in terms of external events (which can be manipulated) instead of internal constructs (which cannot be manipulated or controlled).” Florida Institute of Technology, (August 2002).

The Living With Autism Program acknowledges ABA as a method of instruction and service for children with Autism Spectrum Disorder (ASD). The practice of ABA promotes desired behaviors through easy to learn, step-by-step, instructions utilizing the principles of behaviorism to improve behavior for the benefit of the child with autism.

ABA can be utilized in a variety of environments and with individuals of any age or ability. ABA is commonly practiced through Discrete Trial Training (DTT) utilizing stimuli found in the child’s natural environment to teach the desired skills and behaviors.
