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.
Osgood's ideas influenced Schramm in two important ways: (1) he posited a field of shared experience acting as the background of communication and (2) he added the stages of encoding and decoding as internal responses to the process. [3] Because of these influences, some theorists refer to Schramm's model as the "Osgood–Schramm model". [2] [5]
Charles Egerton Osgood (20 November 1916 – 15 September 1991) was an American psychologist and professor at the University of Illinois. [ 1 ] [ 2 ] He was known for his research on behaviourism versus cognitivism , semantics (he introduced the term " semantic differential "), cross-culturalism , psycholinguistic theory, and peace studies .

The SMCR model is usually described as a linear transmission model of communication. [4] [17] Its main focus is to identify the basic parts of communication and to show how their characteristics shape the communicative process. In this regard, Berlo understands his model as "a model of the ingredients of communication". [24]
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.
Wilbur Schramm is considered the founder of the field of Communication Studies. He was the first individual to identify himself as a communication scholar; he created the first academic degree-granting programs with communication in their name; and he trained the first generation of communication scholars.

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 four-sides model also known as communication square or four-ears model is a communication model described in 1981 by German psychologist Friedemann Schulz von Thun. [2] [3] It describes the multi-layered structure of human utterances.
