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 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.
[8] [36] Berlo sees thought or reasoning as an additional communication skill relevant both to encoding and decoding. [37] The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8]
The above-mentioned criticisms often lead to another objection: that Lasswell's model is outdated and therefore lacks usefulness in comparison to more modern models. However, despite being one of the oldest models of communication, Lasswell's model is still being used today.
Medium theory is a mode of analysis that examines the ways in which particular communication media and modalities impact the specific content (messages) they are meant to convey. It Medium theory refers to a set of approaches that can be used to convey the difference in meanings of messages depending on the channel through which they are ...
Barnlund's model of interpersonal communication. The orange circles represent the communicators. The other colored areas symbolize different types of cues. Communication takes place by decoding cues (orange arrows) and encoding behavioral responses (yellow arrows). Barnlund's model is an influential transactional model of communication. It was ...
A common objection is based on the fact that it is a linear transmission model: it conceptualizes communication as a one-way process going from a source to a destination. Against this approach, it is argued that communication is usually more interactive with messages and feedback going back and forth between the participants.
Buller and Burgoon discount the value of highly controlled studies – usually one-way communication experiments – designed to isolate unmistakable cues that people are lying. Therefore, IDT is based on two-way communication and intended to describe deception as an interaction communicative process. [14]
