Lasswell's model is one of the earliest and most influential models of communication. [3]: 109 It was first published by Harold Lasswell in his 1948 essay The Structure and Function of Communication in Society. [4] Its aim is to organize the "scientific study of the process of communication".
Gerhard Maletzke applied the SMCR model to mass communication in his 1978 book The Psychology of Mass Communication. He sees communication as a form of persuasion. He discusses factors influencing the behavior of the communicators and the outcome of the communication, like the image source and receiver have of each other.
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.
They may be a form of self-mimicry, to draw a predator's attention away from the prey's most vulnerable body parts. Or they may serve to make the prey appear inedible or dangerous. Eyespot markings may play a role in intraspecies communication or courtship; a well-known example is the eyespots on a peacock's display feathers.
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.
The eyespot apparatus (or stigma) is a photoreceptive organelle found in the flagellate or (motile) cells of green algae and other unicellular photosynthetic organisms such as euglenids. It allows the cells to sense light direction and intensity and respond to it, prompting the organism to either swim towards the light (positive phototaxis ...
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.
One key activity in communication theory is the development of models and concepts used to describe communication. In the Linear Model, communication works in one direction: a sender encodes some message and sends it through a channel for a receiver to decode. In comparison, the Interactional Model of communication is bidirectional. People send ...
