The document discusses various models of communication, highlighting their systematic representations and functions, with a focus on the linear, transactional, and interactional models. It explores the Lasswell model, which addresses the components of communication, and the Shannon-Weaver mathematical model, detailing how noise affects the communication process. The Osgood-Wilbur Schramm model is also examined, emphasizing its circular nature and the importance of feedback.

1. MODELS OF COMMUNICATION
Dr. J. JANARDHAN

2. MODELS OF COMMUNICATION
 Comm. models are systematic representations
 Models help in understanding how works can be done
 Models shows the process metaphorically and in symbols
 It can encourage traditional thinking and stereotyping
 But, can also omit some major aspects of human
communication

3. TYPES OF MODELS COMMUNICATION
 There are three general types of communication models
Linear Model
Transactional Model
Interactional Model

4. LINEAR MODEL

5. TRANSACTIONAL MODEL

6. INTERACTIONAL MODEL

7. LASSWELL MODEL
 Western models are having origin in Aristotle’s Rhetoric
 Its made up of three elements
The Speaker
The speech
The listener
 Search of all the possible means of persuasion

8. LASSWELL MODEL
 Harold D. Lasswell describes an act of communication is
to answer to
Who
Says what
In which Channel
To whom
With what effect?

9. LASSWELL MODEL


10. FUNCTIONS
 Communication performs three functions.
i. Surveillance of the environment
ii. Correlation of components of society
iii. Cultural transmission b/w generations

11. PRIMARY GOAL
 The message flows in a multicultural society with multiple
audiences.
 The notion of transmission and transfer of information for
intended effects
 The primary goal is influence through persuasion

12. ADVANTAGES/DISADVANTAGES
ADVANTAGES
 Its easy and simple
 It suits for almost all types of communication
 The concept of effect
DISADVANTAGES
 No scope for feedback
 It doesn’t talk about noise
 Linear model only

13. SHANNON & WEAVERS’
MATHEMATICAL MODEL

14. MATHEMATICAL MODEL OF COMM.
 Shannon theory talks about ‘Signal transmission’
 He introduced Qualitative & Quantitative model
 Its develop the effective comm. b/w sender and receiver
 It also developed to improve the ‘technical comm.’
 The model talks about ‘Noise’

15. MATHEMATICAL MODEL OF COMM.
 Shannon developed model to separate noise from the
transmitter
 Shannon focused on engineering aspects
 Weaver added the ‘Philosophical aspects’
 Weaver widely applied Shannon’s model to the human
communication

16. MATHEMATICAL MODEL OF COMM.
 This model deals with various elements like
Information Source
Transmitter
Channel
Receiver
Destination and Noise

17. ADVANCES & DIS-ADVANCES
 Simplest model
 It attracts both academicians & information theorists
 It is a sender and receiver based model
 More effective in ‘Person-to-Person’ communication
 Understanding ‘Noise’ will help to solve the problems

18. LEVEL OF NOISE
 Noise finds in three level
i. Technical problem- Simple to understand
ii. Semantic problem- Hard to solve
iii. Effective problem- As manipulation or
Propaganda
 The three levels are interrelated and interdependent
 The source is seen as the decision maker

19. OSGOOD-WILBUR SCHRAMM MODEL
 Sharing of information, ideas or attitudes
-Wilbur Schramm
 Communication requires at least three elements
Source
Message
Destination

20. OSGOOD-WILBUR SCHRAMM MODEL
 It is a circular model
 Communication ends where it started off

21. WILBUR SCHRAMM MODEL
 It breaks the sender and receiver model
 It can happen within our self or two people
 Each person acts as both sender and receiver
 Semantic noise is introduced in the model
 It occurs when sender and receiver apply different
meaning to the same message

22. WILBUR SCHRAMM MODEL-Advn
 It’s a dynamic model
 It shows why redundancy is an essential part
 There is no separate sender and receiver
 Communication will be circular in nature
 Feedback-Central feature
