Nonverbal communication involves using wordless messages to convey meaning and includes facial expressions, gestures, body language, touch, use of space, and vocal cues. It plays an important role in first impressions and supports, regulates, emphasizes, and sometimes contradicts verbal communication. Nonverbal communication can be ambiguous as the same gestures may have different meanings depending on context and a single meaning may be conveyed through various nonverbal codes. It involves the study of kinesics, proxemics, chronemics, haptics, and other areas.
