Behavior analysis is the systematic study of variables that influence human and non-human organisms. It emphasizes careful measurement of observed behavior, along with an appreciation of the role of environment just before and just after the response. Prediction and control of behavior are of vital interest to mankind, and behavior analysis offers the tools to accomplish this. We have learned through careful experimentation that behavior is governed by its consequences, and we have found that this seemingly simple principle is applicable in a variety of practical situations.
Applied behavior analysis (ABA) is a discipline concerned with the application of behavioral science in real-world settings such as clinics or schools with the aim of addressing socially important issues such as behavior problems and learning. Specifically, ABA refers to a systematic approach to the assessment and evaluation of behavior, and the application of interventions that alter behavior. Over the past 40 years, several thousand published research studies have documented the effectiveness of ABA across a wide range of behaviors, settings, and populations. Procedures derived from the discipline of ABA have been implemented in areas such as:
