Nonverbal communication (NVC) between people is communication through sending and receiving wordless clues. It includes the use of visual cues such as body language (kinesics), distance (proxemics) and physical environments/appearance, of voice (paralanguage) and of touch (haptics).
1. Facial Expressions
Facial expressions are responsible for a huge proportion of nonverbal communication. Consider how much information can be conveyed with a smile or a frown. The look on a person's face is often the first thing we see, even before we hear what they have to say.
While nonverbal communication and behavior can vary dramatically between cultures, the facial expressions for happiness, sadness, anger, and fear are similar throughout the world.
2. Gestures
Deliberate movements and signals are an important way to communicate meaning without words. Common gestures include waving, pointing, and using fingers to indicate numeric amounts. Other gestures are arbitrary and related to culture.
In courtroom settings, lawyers have been known to utilize different nonverbal signals to attempt to sway juror opinions.
An attorney might glance at his watch to suggest that the opposing lawyer's argument is tedious or might even roll his eyes at the testimony offered by a witness in an attempt to undermine his or her credibility. These nonverbal signals are seen as being so powerful and influential that some judges even place limits on what type of nonverbal behaviors are allowed in the courtroom.
3. Paralinguistics
Paralinguistics refers to vocal communication that is separate from actual language. This includes factors such as tone of voice, loudness, inflection, and pitch. Consider the powerful effect that tone of voice can have on the meaning of a sentence. When said in a strong tone of voice, listeners might interpret approval and enthusiasm. The same words said in a hesitant tone of voice might convey disapproval and a lack of interest.
Consider all the different ways simply changing your tone of voice might change the meaning of a sentence. A friend might ask you how you are doing, and you might respond with the standard "I'm fine," but how you actually say those words might reveal a tremendous amount of how you are really feeling. A cold tone of voice might suggest that you are actually not fine, but you don't wish to discuss it.
