The science of human behavior—including the concepts of science, knowledge, analysis, functional relationships, causation, and control—is comprised of assumptions and terminology that are part of a unitary and comprehensive conception of human behavior. These concepts and terms rest upon the assumptions of physical determinism and scientific method.
The study, control and prediction of human behavior requires direct observation of behavior and objective specification of the environmental events that control and influence its expression. The assumptions of the science of behavior are based on empirical concepts of causation, pragmatism, and parsimony.
Behavior analysts avoid reference to mental or other events not verifiable by objective observation and measurement. Behavior analysis is best understood as a philosophy combining radical behaviorism and functional contextualism--where the evolutionary engines of variation, selection and retention within a context guide an understanding of human behavior, thought and expression. Technical developments within the science now make it possible for ABA practitioners to engineer the development of more effective and meaningful lives for individual children and their families.
