• Introduction

• Models are symbolic representations of structures, objects or operations.

• They are useful theoretical constructs that are frequently used in social sciences for explanatory purposes.

• They may be used to show the size, shape or relationship of various parts or components of an object or process.

• A model may also be useful in explaining the working of a system.

• Concepts of model

• i. It is representation of the process of communication in the same sense that a blueprint is a representation of house.

• ii. Models are symbolic representations of structures, objects or operations.

• Purpose of models

• Communication models serve three main purposes• i. they describe the process of communication • ii. they visually show relationship among the variables

involved in communication and • iii. they aid in finding and in correcting communication

problems

1. Aristotle's Model of Communication

• Aristotle’s Model of Communication (384-322 BC)The earliest model of communication was the symmetrical and simple model developed by the great Greek philosopher Aristotle. Aristotle in his model includes the five essential elements of communication, i.e., the speaker, the speech or message, the audience. This model is most applicable to public speaking.

• This model is also called as persuasive model .

. Lasswell's Model (1948) 

• Lasswell has given us another simple model. • His model belongs specifically to the area of mass

communication. • He argued that to understand the process of mass

communication one needs to study each of the stages in his mode. "Who says what, in which channel, to whom, under what circumstances , with what effect.“

• This model is called rudimentary model .

Shannon and Weaver  model  (1949)  

• The preconception of the academic field of mass communication were heavily influenced by the engineering model of Shannon and Weaver (1949) Communication was conceived as a linear act of transmission of a message from a source to a receiver via a signal producing transmitter.

• A component called 'noise' acknowledged the presence of context in the electrical engineering model.

• This model is also called as Mathematical model .

Berlo’s Model 1960

• Berlo’s Model • 1. Code is a system of signals for communication. • 2. Encode means to put the message into code. • 3. Channel means the medium through which the signals

move. • 4. Decoder means which converts the message in the code into

ordinary language which may be easily understood.

C.E. Osgood - Schramm Model (1975)

• To the circular model, we have added boxes and arrows showing the influence of noise and personality is a helix used as a model by Frank E.X. Dance.

• He felt that circular models were better than straight - lines ones like Shannon- Weaver, but that they had a built in error since they showed communication ending up where it started off.

• In fact as an act of communication goes on, the noise gets less (because the communicators get more used to handling the channel / model) and personality becomes more helpful (because, as communicators get to known each other and the subject, they adjust to each other and fill gaps in their knowledge).
