This document discusses several models of communication: - Aristotle's model from 300 BC focused on oratory and effective delivery. - Laswell's 1948 model examined who communicates what through which channel to whom with what effect. - Shannon and Weaver's 1949 model focused on information theory and the transmission and reception of messages. - Schramm's 1954 model stated communication requires common experiences between sender and receiver. - Berlo's 1960 model identified factors controlling the elements of communication like source, message, channel and receiver. - Dance's 1967 model viewed communication as evolving over time based on past experiences.

7. Harold Laswell Communication
Model

8. • “ Who says what in which channel to
whom with what effect?”
• The use of medium is very crucial in
this model. (Examples are radio,
Television and other gadgets).

Model

9. Shannon and Weaver
Communication Model

10. • This model is focused of information
theory; The Transmission and
Reception of message.
• Transmitter and Receiver - used by the
sender and receiver during the act of
communication.
Shannon and Weaver
Communication Model

11. • Noise maybe in:
1. Static Sources (Example: Solar
Flares.)
2. Unusual weather conditions.
3. Electronic Equipment that interferes
with the signal.
4. Environmental Phenomena.
Shannon and Weaver
Communication Model

12. Willbur Schramm Communication
Model

13. • “If there is no commonality in
the sender and receiver field of
experience. Then,
communication does not takes
place.”
Willbur Schramm Communication
Model

14. Willbur Schramm Communication Model

15. • In this model, Communication
becomes a continuous process of
message and feedback.
• It allows interaction.

16. David Berlo Communication Model
( A Model of The Ingredients of Communication)

17. • The model identifies the
controlling factors for the major
elements of communication (
Source, Message, Channel and
Receiver)

18. Frank Dance Communication Model

19. • Communication evolves from the very first
day (origin) until the existing moment.
• Communication is largely dependent on its
past.
• Concept of time.
• Communication process is the product of
what we learnt.
