The article discusses the various dimensions of applied behavior analysis, which include the applied, behavioral, analytic, technological, conceptual systems, effectiveness, and generality dimensions. The applied dimension focuses on socially important issues rather than theory. The behavioral dimension examines measurable behavior changes. The analytic dimension demonstrates that stimuli are responsible for behavioral changes. The technological dimension provides detailed descriptions to allow for replication of results. The conceptual system dimension requires that studies be theoretically based. The effectiveness dimension applies to socially significant behavioral changes that are obvious. The generality dimension concerns whether behavioral changes persist across environments.
