Which procedure involves blocking or masking sensory stimulation from a behavior?

The procedure that involves blocking or masking sensory stimulation from a behavior is sensory extinction. This approach is specifically designed to reduce or eliminate behaviors that are maintained by sensory reinforcement. For example, if a child engages in a behavior because it provides them with sensory input (like spinning or rocking), masking or blocking that sensory stimulus would diminish the occurrence of the behavior over time. Sensory extinction directly addresses the need for the sensory feedback that reinforces the action, making it a key strategy for behavior modification in situations where the behavior is primarily driven by sensory experiences.

In contrast, other procedures such as escape extinction or attention extinction focus on different forms of reinforcement, such as avoiding demands or seeking social interaction, rather than targeting the sensory aspects of behavior. Behavior interference generally refers to actions taken to disrupt a behavior rather than to reduce its sensory reinforcement. Thus, sensory extinction is the most appropriate answer for this question.
