What dimension of ABA focuses on the application of procedures?

The correct answer is the dimension of Applied. This dimension of Applied Behavior Analysis (ABA) emphasizes the significance of using procedures to address socially important behaviors. It involves selecting interventions that are relevant to the individual's needs and that hold practical value in real-life contexts. The term "applied" indicates that the focus is on behaviors that are directly related to improving the quality of life for individuals and enhancing their functional skills within their environment.

In the context of ABA, this dimension ensures that practitioners are not just working with abstract concepts or behaviors that are of little importance but are instead committed to making meaningful changes that the client needs and benefits from. Procedures must therefore be implemented in a way that is effective and aligned with the practical, everyday challenges faced by individuals, ensuring that the interventions are not just technically sound but have a significant impact on the clients' lives.

This focus on real-world applicability distinguishes it from the other dimensions, which pertain to different aspects of implementing behavior analysis practices, such as the strategies used or the effectiveness of those strategies in producing desired outcomes.
