The model’s aim is specially designed to develop effective communication between the sender and receiver. At first the model was developed to improve the communication through telephone and other technologies which could be implemented. Not only does it serve to aid technologies at that point in time but it also aims to target in the future inventions and developments.
Breakdown Of Model
In this model there are various keywords like transmitter, message, receiver, destination, encode and decode.
The originator of message or the information source or known as the person initiating the conversation.
The transmitter which converts the message sent into signals.
Basically a reverse process of an encoder.
The destination of the message from the sender.
Flow Of Model
Through various research, I realised that this model is effective in serving its purpose without much thinking. To make it easier to understand, basically the sender will prepare the information he wants to transmit to the receiver. He will then encode it to a transmitter and the message will be passed through a channel. Over there, there are many factors which can affect the flow of this conversation. The main factor that would cause this disruption is noise pollution which comes in many different forms. Be it a car honking in the middle of the streets to the subtle cries of a baby, noise is something that one cannot avoid. Once the receiver receives the encoded message, he will then decode it and give his feedback of the message received, continuing the flow of this model.
Changes To the Model
However, there was an issue in the original version of this model. The model only shows that conversation only goes one way and there was no way the receiver could respond or acknowledge. That’s where American mathematician, Norbert Wiener suggested the inclusion of a feedback in the loop which connects the receiver to the original sender therefore, completing the loop.
Completed Vs Uncompleted Model
If the completed model is being used, the receiver can provide the sender with an acknowledgment or response saying that the message has been received and decoded. It can even lead to clarifications that the received message has the correct information. Therefore, this continues the flow of the conversation.
If the uncompleted model is being used, any factors affecting the process of the message being sent over will result in the message being incomplete or distorted. The receiver will have no way of requesting the message to be sent again, resulting in the end of the conversation.
For even further understanding, I have created this simple mind map to show how the model works in a real world scenario. As you can see, the father’s message was transmitted to his daughter but as a result of the noise generated by the television, the daughter could not decipher his message. Her feedback would be received by the father and then he will then repeat his message which will continue this conversation.
Advantages & Disadvantages
Of course in everything there are always its good and bad sides. Lets discuss them!
- The model identifies the factor that causes the message to be disrupted during the process.
- The model shows that communication is a two way process.
- Explains about effective communication.
- The model was originally used to be applied to telecommunication rather than human communication.
- Feedback feels like is less important compared to the message being sent out.
Despite it being an idea that originated in 1954, the Shannon & Weaver’s Model is still relevant in our current society. From us communicating with our loved ones, it even shaped how technology works today. The Shannon-Weaver model of course isn’t flawless. Many criticised that the model makes communication too simple and it being a one way thing. With that being said, nothing changes the fact that the principles of this model laid the foundation of many modern models and theories.
