ABA is a well-developed scientific discipline that focuses on the analysis, design, implementation, and evaluation of social and other environmental modifications to produce meaningful changes in human behavior.
ABA includes the use of direct observation, measurement, and functional analysis of the relations between environment and behavior. ABA uses changes in environmental events, including antecedent stimuli and consequences, to produce practical and significant changes in behavior. These relevant environmental events are usually identified through a variety of specialized assessment methods.
ABA is based on the fact that an individual’s behavior is determined by past and current environmental events in conjunction with organic variables such as their genetic endowment and physiological variables. Thus, when applied to ASD, ABA focuses on treating the problems of the disorder by altering the individual’s social and learning environments.
