2. Aristotle’s Model of Communication
The Aristotle’s communication model is a speaker
centered model as the speaker has the most important role
in it and is the only one active. It is the speaker’s role to
deliver a speech to the audience. The role of the audience
is passive, influenced by the speech. This makes the
communication process one way, from speaker to receiver.
While exploring the human nature scientifically,
Aristotle developed a linear model of
communication for oral communication known as
Aristotle’s Model of Communication. This is
considered as the first model of communication
and was proposed before 300 B.C . It is also the
most widely accepted among all communication
models.

3. ● Aristotle Model is mainly focused on speaker and
speech. It can be broadly divided into 5 primary
elements: Speaker, Speech, Occasion, Audience
and Effect.

4. There are few criticisms around this model. Some
of them are:
● There is no concept of feedback, it is one way
from speaker to audience.
● There is no concept of communication failure
like noise and barriers.
● This model can only be used in public
speaking.

5. Lass Well's Model of Communication
Though Lasswell’s model was developed to analyze
mass communication, this model is used for
interpersonal communication or group communication
to be disseminated message to various groups in
various situations.
Lasswell's communication model was
developed by communication theorist Harold
D. Lasswell (1902-1978) in 1948. Lasswell’s
model of communication (also known as
action model or linear model or one way
model of communication) is regarded as one
the most influential communication models.

7. ● The major criticism of Lasswell’s Model is that it does
not include feedback and it ignores the possibility of
noise. Without feedback, a communication process
can not be fruitful. Lasswell’s model is very linear and
does not consider barriers in the communication
process.
● The model is also criticized for being very general and
only including very traditional topics. The model is very
simplistic. The model is said to be propaganda based
as it is more focused on the resulting outcome and
generally used for media persuasion.

8. Shannon and Weaver Model of
Communication
● In 1948, Shannon was an American mathematician,
Electronic engineer and Weaver was an American
scientist both of them join together to write an article in
“Bell System Technical Journal” called “A
Mathematical Theory of Communication” and also
called as “Shannon-Weaver model of communication”.
● This model is specially designed to develop the
effective communication between sender and receiver.
Also they find factors which affecting the
communication process called “Noise”. At first the
model was developed to improve the Technical
communication. Later it’s widely applied in the field of
Communication.

9. ● The model deals with various concepts like
Information source, transmitter, Noise, channel,
message, receiver, channel, information destination,
encode and decode.

10. Example of Shannon-Weaver model
communication process
A businessman sends a message
via phone text to his worker about
a meeting happening about their
brand promotion. The worker does
not receive the full message
because of noise. It goes like this:
Businessman: We have a
meeting at the office ("at 8 am"
goes missing due to phone
network disruption or noise)
Worker (feedback) : At what
time?
1.Sender : Businessman
2.Encoder : Telephone
network company
3.Channel : Mobile
network
4.Noise : Distraction in
voice (workplace noises)
5.Decoder: Mobile phone
6.Receiver : Worker

11. Advantage of Shannon-Weaver model of
communication
● Concept of noise helps in making the
communication effective by removing the noise
or problem causing noise.
● This model takes communication as a two way
process. It makes the model applicable in
general communication.
● Communication is taken as quantifiable in
Shannon Weaver model.

12. ● It can be applied more for interpersonal
communication than group communication and mass
communication.
● Receiver plays the passive part in the communication
process as sender plays the primary role that sends
messages.
● Feedback is taken as less important in comparison to
the messages sent by the sender.
● The model is taken by some critics as a "misleading
misrepresentation of the nature of human
communication" as human communication is not
mathematical in nature.
