Which intervention technique involves adjusting the value of a reinforcer?

The correct choice is motivated operations. This intervention technique is based on the principles of behavior analysis, particularly regarding how certain variables can influence the effectiveness of reinforcement and behavior. Motivating operations (MOs) refer to environmental events or conditions that alter the effectiveness of a reinforcer. They increase or decrease the desirability or value of a reinforcer, thereby impacting behavior.

For instance, if a person is deprived of a specific food item, that food may become more reinforcing due to its increased value; thus, the person is more likely to engage in behaviors that lead to the acquisition of that food. Conversely, if they have had plenty of that food recently, the reinforcing value diminishes, and they may show less interest in behaviors associated with that item.

This concept is fundamental in applied behavior analysis as it allows practitioners to understand and influence behavior based on the changing values of reinforcers within an individual's environment. Therefore, adjusting the value of a reinforcer to increase desired behaviors is an essential aspect of implementing effective interventions.
