The concept of physical proximity is associated with which of the following types of behavior modification?

Prompting refers to providing cues or hints to encourage a desired behavior but does not specifically entail physical closeness. It can occur verbally or through gestures from a distance. The key aspect of prompting is the guidance provided, rather than the physical proximity of the teacher to the student.

Person-to-person dialogue emphasizes verbal communication between individuals. While it may involve being physically close, it primarily focuses on the exchange of spoken words. This type of interaction does not inherently relate to the nonverbal cues that physical proximity embodies in behavior modification.

A reactive approach involves responding to behaviors after they occur, rather than proactively using physical presence to modify behavior. This method can be important in behavior management but lacks the emphasis on physical closeness and proactive nonverbal engagement that characterizes nonverbal teacher interaction.
