This document discusses non-verbal communication and emotional perception. It covers four main areas of non-verbal communication: kinesics (body language), proxemics (personal space), paralinguistics (vocal tones), and other complementary aspects like clothing. Within kinesics, it examines facial expressions, body posture, gestures, and the meanings they can convey during interactions like job interviews. Regarding proxemics, it outlines the four zones of interpersonal distance (intimate, personal, social, public) based on distance from another person. The document emphasizes that non-verbal signals actively communicate our feelings and attitudes even when we may not be aware of them.
