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.
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.
Poole's multiple sequence model states that different groups make decisions through the applications of different sequences. This model rejects the idea that decision making occurs in separate, succinct phases, as other rational phase models suggest. [1] Rather, Poole theorized that decision making occurs in clusters of linking communication.
Communication theories vary substantially in their epistemology, and articulating this philosophical commitment is part of the theorizing process. [1] Although the various epistemic positions used in communication theories can vary, one categorization scheme distinguishes among interpretive empirical, metric empirical or post-positivist, rhetorical, and critical epistemologies.

One of the subelements of the message is its code. [8] In communication theory, a code is a sign system to express information or a system of rules to convert information from one form into another. [49] Berlo defines code as "any group of symbols that can be structured in a way that is meaningful to some person".
Communicology is the scholarly and academic study of how people create and use messages to affect the social environment. Communicology is an academic discipline that distinguishes itself from the broader field of human communication with its exclusive use of scientific methods to study communicative phenomena.
As one of the earliest models of communication, Lasswell's model has been very influential in the field of communication studies. In 1993, the communication scholars Denis McQuail and Sven Windahl referred to Lasswell's model as "perhaps the most famous single phrase in communication research."
D. Lawrence Kincaid (born 1945) is an American communication researcher who originated the convergence theory of communication. He was a senior advisor for the Research and Evaluation Division of the Center for Communication Programs and an associate scientist in the Faculty of Social and Behavioral Sciences at the Johns Hopkins Bloomberg School of Public Health.
