2 Communication Models

The Transmission Model

This model was created by Claude Shannon. He was able to predict the decay of a message over a long distance by working out a mathematical formula. Warren Weaver saw that Shannon's model had broader implications. This model is very easy to understand. It puts the communication process in a straight line. The sender encodes a message, which is sent through the channel, interfered by noise. David Berlo recognized that the Shannon-Weaver model describes more than a telephone transmission. One can use this model for nearly all verbal interaction. Basic components of this model include: Sources and receivers (speaker and listener), Encoding and decoding (people encode messages by putting converting thoughts into their message, and they decode when they convert messages back into thought), Messages (names the substance of communication, what is being said, it can be verbal or non-verbal), Channel (the medium which the message circulates, the air which the message passes or electronic signals which converts the message), Noise (static in the phone line, or anything that hinders the communication process).

The Transactional Model

This model transfers the basics of the Shannon-Weaver model and focuses more on the heart of the communication process. It focuses more on the theory that we are always sending messages even if they are non-verbal, unintentional or quite explicit. The Shannon-Weaver model's heart is the transmission of the communication process, but the transactional model's heart is shared meaning.
