For Schramm, communication is about sharing information or having a common attitude towards signs. His model is based on three basic components: a source, a destination, and a message. The process starts with an idea in the mind of the source. This idea is then encoded into a message using signs and sent to the destination.
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
A model of communication is a simplified presentation that aims to give a basic explanation of the process by highlighting its most fundamental characteristics and components. [16] [8] [17] For example, James Watson and Anne Hill see Lasswell's model as a mere questioning device and not as a full model of communication. [10]
The Shannon–Weaver model is one of the first and most influential models of communication. It was initially published in the 1948 paper "A Mathematical Theory of Communication" and explains communication in terms of five basic components: a source, a transmitter, a channel, a receiver, and a destination. The source produces the original message.
Barnlund's model is based on a set of fundamental assumptions holding that communication is dynamic, continuous, circular, irreversible, complex, and unrepeatable. Cues are of central importance in Barnlund's model. A cue is anything to which one may attribute meaning or which can trigger a response.
The source–message–channel–receiver model is a linear transmission model of communication. It is also referred to as the sender–message–channel–receiver model, the SMCR model, and Berlo's model. It was first published by David Berlo in his 1960 book The Process of Communication. It contains a detailed discussion of the four main ...
Four-sides model. The four-sides model (also known as communication square or four-ears model) is a communication model postulated in 1981 by German psychologist Friedemann Schulz von Thun. According to this model every message has four facets though not the same emphasis might be put on each. The four sides of the message are fact, self ...
The encoding/decoding model of communication emerged in rough and general form in 1948 in Claude E. Shannon 's "A Mathematical Theory of Communication," where it was part of a technical schema for designating the technological encoding of signals. Gradually, it was adapted by communications scholars, most notably Wilbur Schramm, in the 1950s ...
