Why do people use gestures and facial expressions?

Posted on Friday 23 November 2012 | No Comments


From research it has been established that most of the communication i.e. at least 70% is done in non-verbal ways like gestures, postures, facial expressions, body language, etc.
Using gestures, postures, body language is an automatic habit of human beings to make more meaningful emphasization and to gain support and strength within himself or herself. Non-verbal features of communications are used to modify the verbal communication. That is exactly why we add non-verbal communication to our words knowingly or unknowingly when we interact using word with other individuals or people.


When communication takes place without words and language it is considered as non-verbal communication. This form of communication includes the internal stimuli of human beings. Other than spoken language using words, communication in writing, gestures, body language comprise the non-verbal category of communication.



Although verbal and non-verbal communication are inter-related and inter-dependent. There are 6 ways in which verbal and non-verbal features of communication overlap. They are mentioned below.


- repeating
- contradicting
- substituting
- complimenting
- accenting
- regulating

Repeating is when non-verbal behavior are sometimes repeated after what has been said. For example, asking a person to get out and then pointing the finger at the door.


Contradicting occurs when sometimes non-verbal features contradict what has been said.
Substituting is when non-verbal can be used in place of verbal communication. For example, just a stare into your lover’s eyes can substitute for the words ‘I love you’.


Complimenting is when non-verbal features of communication can elaborate or modify verbal behavior. For example, a student may show nervousness or tension before taking a test or appearing an exam but relaxes as he/she gets the question paper in hand.


Accenting is when non-verbal accents verbal behavior. It is when for example the hand and the head emphasize what is being said in words.


Regulating is when non-verbal behavior regulates the flow of verbal conversation. For example, eye contact and head nods may signal who is or not paying attention.


Hence it is seen that people mostly use non-verbal forms of communication in order to express better and emphasize what they are saying in words.
