This document discusses proxemics, which is the study of how humans use space in communication. There are four types of personal spaces: intimate space (touching), personal space (1-4 feet), social space (4-12 feet), and public space (12+ feet). Different cultures have different standards for personal space. Proxemics also examines physical space arrangement and how it conveys power and status. Personal territory refers to one's immediate space, while primary, secondary, and public territories describe increasingly larger social spaces.
