This particular concept of communication gradually got narrowed down to various categories of which the very common are mass communication, intrapersonal communication and interpersonal communication. These categories became subjects of interest in fields of both communication and psychology and the one that the masses can identify themselves with, is interpersonal communication.
The concept of interpersonal communication is not as difficult as it sounds. It is as simple as having a conversation! Yes! That is what it is. When two people communicate with each other, we call it 'interpersonal communication'. You call it a conversation, psychology calls it interpersonal communication. That is because psychology views it as not just a conversation, but your way of exchanging ideas, your body language, your ability to maintain eye contact and your grip on the topic. It is not just words that get communicated! Your eyes, your body language and your way of speaking to the other person speak more than mere words.
Well, to simplify, if while talking, you are unable to maintain eye contact and show restlessness then there are chances that you are either lying or hiding something even if you do not say it out! Technically, it's a message sending and message receiving process but I would rather go for the simpler version.
The concept may be new but its roots can be traced back to prehistoric times. Even if we were devoid of a civilized society and a script, we did know to communicate! We chose to communicate through sounds and actions, couples had to express after all! Thus, interpersonal communication found itself divided into two. One is the verbal communication and the other is non-verbal. As the name suggests, verbal communication is communication through words injected with sense and grammar. This is where communication became easy. What I find interesting is non-verbal communication. Non-verbal communication came with choices. People used their own way to communicate. Some used the sign language, while some used symbols on paper.
There is another interesting side to interpersonal communication. People show more willingness to talk to a person who is well dressed and impressive. Certain people make their choices based on their background, life instances, character and the like. When you are comfortable with your partner or you share similarities, communication becomes easier and vice versa.
So, next time you step out and have a conversation with someone, you will know there is a lot more to those words that they speak. Happy conversing!
