Which of the following is a dimension of ABA outlined by Baer, Wolf, and Risley?

The dimension of Applied Behavior Analysis (ABA) as outlined by Baer, Wolf, and Risley refers to the focus of ABA interventions on socially significant behaviors. The term "applied" emphasizes that the practices within this field should be aimed at issues that are relevant and meaningful to individuals and society. This means that interventions should target behaviors that have practical significance and can lead to meaningful changes in the individual's quality of life.

By focusing on applied behaviors, practitioners ensure that their efforts contribute positively to the clients' functioning in real-world contexts, addressing challenges that individuals face in their daily lives. This dimension is crucial because it aligns the goals of behavioral analysis with the personal and social needs of those being supported, ensuring that the interventions are not just theoretically sound but also impactful in a practical sense.

The other dimensions identified by Baer, Wolf, and Risley, while important, do not represent the same focus on social significance as the applied dimension. The emphasis on practicality and relevance is what truly characterizes the notion of "applied" within the context of ABA.
