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.
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.
Schramm's model of communication was published by Wilbur Schramm in 1954. It is one of the earliest interaction models of communication. [1] [2] [3] It was conceived as a response to and an improvement over earlier attempts in the form of linear transmission models, like the Shannon–Weaver model and Lasswell's model.
The Shannon–Weaver model is one of the first models of communication. Initially published in the 1948 paper "A Mathematical Theory of Communication", it 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.
[2] [10] [12] For example, Greenberg and Salwen state: "Although Lasswell's model draws attention to several key elements in the mass communication process, it does no more than describe general areas of study. It does not link elements together with any specificity, and there is no notion of an active process."
Decoding has both verbal and non-verbal forms of communication: Decoding behavior without using words, such as displays of non-verbal communication. There are many examples, including observing body language and its associated emotions, e.g. monitoring signs when someone is upset, angry, or stressed where they use excessive hand/arm movements ...
One of the more common barriers in communication is the inappropriate use of jargon. Jargon is a fictive language invented by and for the group as a verbal shorthand. It also syllabifies group membership when used properly. The problem with jargon is that it can make words confusing and can be used to conceal the truth.
Contents of communication can be for example photography, data, graphics, language, or texts. Means of communication in the narrower sense refer to technical devices that transmit information. [ 5 ] They are the manifestations of contents of communication that can be perceived through the senses and replace the communication that originally ran ...
