For example, people may nod their heads vigorously when saying “yes” to emphasise that they agree with the other person, but a shrug of the shoulders and a sad expression when saying “I’m fine thanks,” may imply that things are not really fine at all. Non-verbal communication tries to make other people sure about what you are actually feeling or what you actually want to say. Non-verbal communication also helps people to provide feedback to the other person, define and reinforce the relationship between people, convey information about their emotional state and regulate the flow of communication. For example, by signalling to others that they have finished speaking or wish to say something.
There are many different types of non-verbal communication. They include:
1. Body Movements (Kinesics), for example, hand gestures or nodding or shaking the head
2. Para-language, or aspects of the voice apart from speech, such as pitch, tone and speed of speaking
3. Posture, or how people stand or sit, whether your arms are crossed, and so on
4. Closeness or Personal Space (Proxemics), which determines the level of intimacy
5. Eye Contact, where the amount of eye contact often determines the level of trust and trustworthiness
6. Facial Expressions, including smiling, blinking and frowning
7. Physiological Changes, for example, sweating or blinking more when
