Types of Non-verbal communication :-

Body Language :

A simple rule of thumb is that simplicity, directness, and warmth convey sincerity. And sincerity is key to effective communication. A firm handshake, given with a warm, dry hand, is a great way to establish trust. A weak, clammy handshake conveys a lack of trustworthiness. Gnawing one’s lip conveys uncertainty. A direct smile conveys confidence.


Eye gaze :

Looking at another person can indicate a range of emotions like anger, grudge and danger, a dangerous look can tell you someone is unhappy and not comfortable.

Facial Expressions :

The human face can produce thousands of different expressions. These expressions have been decoded by experts as corresponding to hundreds of different emotional states.Our faces convey basic information to the outside world. Happiness is associated with an upturned mouth and slightly closed eyes; fear with an open mouth and wide-eyed stare. Flitting (“shifty”) eyes and pursed lips convey a lack of trustworthiness. The effect of facial expressions in conversation is instantaneous. Our brains may register them as “a feeling” about someone’s character.

Posture :

The position of our body relative to a chair or another person is another powerful silent messenger that conveys interest, aloofness, professionalism—or lack thereof. Head up, back straight (but not rigid) implies an upright character. In interview situations, experts advise mirroring an interviewer’s tendency to lean in and settle back in her seat. The subtle repetition of the other person’s posture conveys that we are listening and responding.

Touch :

The meaning of a simple touch differs between individuals, genders, and cultures. In Mexico, when doing business, men may find themselves being grasped on the arm by another man. To pull away is seen as rude. In Indonesia, to touch anyone on the head or touch anything with one’s foot is considered highly offensive. In the Far East, according to business etiquette writer Nazir Daud, “it is considered impolite for a woman to shake a man’s hand.” Americans, as we have noted, place great value in a firm handshake. But handshaking as a competitive sport can come off as needlessly aggressive, at home and abroad.

Space :

The term proxemics to denote the different kinds of distance that occur between people. These distances vary between cultures. The figure below outlines the basic proxemics of everyday life and their meaning.

Standing too far away from a colleague (such as a public speaking distance of more than seven feet) or too close to a colleague (intimate distance for embracing) can thwart an effective verbal communication in business. 

Paralanguage :      

Attributes of speaking which include the pitch, the tone, the volume, tempo, rhythm, articulation, resonance, nasality and even the accent of the speaker collectively known as paralanguage, we can understand mood and the situation by paralanguage expressions.

Chronemics :

A call at 2 a.m. indicates some kind of emergency.
You reached in a party on time shows you are punctual.
