Nonverbal communication can be referred to as a process or method of passing information without the use of words, either written or spoken. Nonverbal communication is also known as manual communication. It was introduced in 1956 by psychiatrist Jurgen Ruesch and author Weldon Kees in the book Nonverbal communication. There are several nonverbal languages. However, Judee Burgoon recognizes six different nonverbal dimensions, which include:
1. Kinesics or body movement - involves facial expressions, eye contacts, body language, gesture, posture, nodding, and behavior.
2. The vocalic includes volume, rate, and message. A perfect example of this is sarcasm in which the tone of what a person says is different from what they mean.
3. The personal appearance.
4. Our environment and its component.
5. Our personal space - people are very sensitive to their personal space, which is normally reserved for intimacy; this passes a message to a stranger without been said that the other party should keep off.
6. Haptics or touch and chronemics or time.
