This document discusses paralanguage, which refers to nonverbal communication through means other than language such as facial expressions, tones of voice, gestures, eye contact, and spatial arrangements. It notes that paralanguage includes both intentional and unintentional messages and may be complementary, unconscious, or learned. Some behaviors are universal while others are culturally specific. The functions of nonverbal communication include repeating, complementing, contradicting, and regulating verbal communication. Nonverbal communication is divided into kinesics, the study of body language and gestures, and proxemics, the study of use of space and touch. Cultural contexts are important for understanding nonverbal cues.
