What is a Model Response

Models are metaphoric representations of an object or event in an abstract form (often these are represented by pictures).

·      Models allow us to question, clarify and discover.

·      Models can oversimplify.

·      Models can cause confusion to the viewer if they do not have the correct information to decipher the chart. The viewer has to understand the metaphor that is being used in the mode of communication, if it is taken as literal, the viewer will be confused and wrong.

·      Aristotle’s Model of Communication

o   Aristotle believed that  “Rhetoric” is “the faculty of observing in any given case the available means of persuasion”

o   Quintilian (ca. 35-95 A.D), was a roman educator who affectively used Aristotle’s theory of rhetoric to create a training method for a good speaker

§  Discover the proofs, arrange with purpose, clothe the ideas in a clear and compelling form then effectively deliver the product.

·      Aristotle’s Model of Proof according to Kinneavy

a.      Logos, inheres in the content or the message itself

b.     Pathos, inheres in the audience

c.      Ethos, inheres in the speaker

·      Shannon-Weaver Mathematical Model, 1949

o   Claude Shannon designed the most influential early communication models at Bell Telephone Company.

o   He found the most efficient way to transmit electrical signals from one location to another then later created a part in the receiver that corrected differences between transmitted and received signals.

o   Entropy – how much uncertainty is within a given system.

o   Redundancy – the degree to which information is not unique in a given system.

o   Noise – the amount of information not related to the message. This goes from electrical to psychological interferences with the original message.

o   Channel Capacity – the maximum amount of information that a channel can transfer.

·      From Stephen W. Littlejohn’s Theories of Human Communication.

o   “Information is a measure of uncertainty, or entropy, in a situation. The greater the uncertainty, the more the information. When a situation is completely predictable, no information is present.”

·      Berlo’s Model of Communication

o   “the simplest and most influential message-centered model of our time” - Ehninger, Gronbeck and Monroe

o   Adapted from the Shannon-Weaver model

o   Source encodes the message, message goes to the channel and decodes to the receiver.

o   Was significant post WWII

§  Flexible system to include oral, written, electronic and other symbolic generated messages

§  Model put focus on receivers being very important to communicate

§  Weakness – implies human communication is just like machine communication

§  Stresses that most problems in human communication can be solved by simply choosing correctly

·      Schramm’s Model of Communication, 1954

o   One of first to mathematically alter the model of Shannon and Weaver

§  He decided that the sender and receiver should both decode and encode activities + started the way for a two-way message exchange

§  Main weakness was that the model was still only for two parties, no more.

·      Dance’s Helical Spiral, 1967

o   Communication is depicted as an active process. It is constantly moving forward, yet a bit dependent on the past. Thus a flexible communication process is created.

o   Mortensen: “The helix represents the way communication evolves in an individual from his birth to the existing moment.”

o    Weakness – may not be a model according to scientific standards, due to few variables

·      Westley and MacLean’s Conceptual Model, 1957

o   They realized that communication begins when an individual chooses to respond to his/her physical surroundings

o   Strength – allowed for more than simply two people to communicate directly, allowed for feedback

o   Weakness – although it accounted for more variables in typical communication, it did not account for multiple dimensions of communication

·      Becker’s Mosaic Model, 1968

o   Becker believed that most communication connected messages from more than one social situations via TV commercials, public debates, coffee-shop banter, daydreaming, etc.

o   The reference to the receiver that constantly changes cube/mosaic information. Layers of the cube respond to layers of information.

o   Strength – complexity of communication influenced by constantly changing climate

o   Weakness – does not account for more than 3 dimensions in a communication event

·      Functional model, 1951

o   Ruesch and Bateson believed that communication simultaneously functioned at four levels of analysis

§  Level 1 – basic intrapersonal process

§  Level 2 – interpersonal + focuses on overlapping fields of experience.

§  Level 3 – is group interaction, encompassing many people in one location

§  Level 4 – large groups of people

·      Barnlund’s Transactional Model, 1970

o    Most systematic functional model according to Mortensen

Strength - The way that transactions are presented, communicators give meaning to the events in ways that are clear and unique

Weakness – this chart assumes that communication and meaning are the same

·       A Systemic Model of Communication, 1972

o   A change in one part of this model would change the whole system

·      Brown’s Holographic Model, 1987

o   An argument is like a hologram because you are unable to see all sides of the argument at once – only parts of it are highlighted at once.

·      A Fractal Model

o   Benoit Mandelbrot was interested in using irregular shapes in mathematical formulas

o   Thus he created a term called “Fractual” to be a simple repeating shape that’s created by the same formula

o   This lead to a change in computer graphics, using the fractal formula natural looking virtual landscapes could be created

o   Fractual geometry is related to chaos theory (which is used in computer generated landscapes, washing machines, and the stock market)

o   In relation to communication, we are able to see the almost infinite mass that makes up a communication event
