This document discusses various aspects of non-verbal communication including body language, proxemics, chronemics, haptics, and paralanguage. It explains that non-verbal communication conveys more information than verbal communication through gestures, facial expressions, eye contact, touch, use of space, time, and other cues. Certain non-verbal behaviors can indicate feelings, attitudes, relationships, and cultural or social norms between individuals and within groups. Mastering non-verbal communication skills is important for effective interpersonal interactions.
