Communication Theory Models

• Communication is transferring information from one place, person, or group to another
• Communication theory is a proposed description of communication phenomena
• Communication theory includes the relationships among phenomena, a storyline, and an argument
• Communication theory allows for talking about and analyzing key events, processes, and commitments that form communication
• Communication has led to the formulation of many theories

Aristotle Model

• Speaker constructs messages to have persuasive effects on listeners
• The speaker's view is: Speaker --> Argument --> Speech --> Listener

Lasswell Model

• Speaker constructs messages and select a channel to have range of effects on listeners
• Lasswell's view: Who (Speaker) --> What (Message) --> Channel (Medium) --> Whom (Audience) --> Effect
• In Lasswell's model feedback may not be conveyed, transforming an effect on those involved

Shannon-Weaver Model

• Communication includes all procedures by which one mind may affect another
• Communication involves written and oral speech, music, pictorial arts, theatre, ballet, and all human behaviour
• Communication works when the source encodes a message and transmits it through a channel to a receiver

Schramm Model

• Communication works when the source encodes a message and transmits information through a channel to a receiver, given they have a shared field of experience
• The directional flow is one way

Katz-Lazarsfeld Model

• The source encodes messages and transmits information through mass media to opinion leaders, who then relay it to the public
• Information flows in two steps
• Step 1: From Media to Opinion Leaders
• Step 2: From Opinion Leaders to Masses

Westley-MacLean Model

• The source selectively encodes messages
• Information is transmitted in a modified form to a receiver
• The receiver decodes and encodes
• Information is then transmitted to other individuals with feedback at every step

Dance Model

• Individuals encode and decode messages based on previous communication experiences
• In 1967 it may be seen as an interesting development of the Osgood and Schramm circular model

Watzlawick-Beavin-Jackson Model

• Individuals exchange messages through behaviour
• The meaning of these messages vary with each person based on the communication relationship between them

Thayer Model

• Individuals generate and disseminate, as well as acquire and process information in an ongoing, dynamic process
• Thayer's Organisational Communication Model includes technological, organizational, inter-personal and personal steps

De Vito Model

• Individuals send and receive messages which are distorted in context
• Those messages have some effect and provide opportunities for feedback
• Joseph A. DeVito created the 6-Stage Model of Relationships
• The six-stage model focuses on basic design of each stage and analyses movement between stages
• This model assumes awareness of principles/assumptions of stage models and a basic understanding of other stage models

The lesson explores different communication theory models, including Aristotle, Lasswell, and Shannon-Weaver. It describes communication as the process of transferring information and examines the relationships. These models allow analysis of events, processes, and commitments that form communication.
