MODELS OF COMMUNICATION By: Anuj Sachdev Varsha Dhankani Manish Punjabi


Communication Person’s desire to share or exchange idea, thought or feeling. Involves a sender, a message, a medium and a receiver

Models of Communication:

Models of Communication Linear model Shannon- Weaver Model TWO-WAY COMMUNICATION PROCESS

Linear Model Of Communication:

Linear Model Of Communication The earliest conceptualization of communication Given by Harold Lasswell One way process Five basic questions: Who? Says What? To Whom? Using which channel? With what effect?


Assumptions In this model it is assumed that --- While the message the is passed by any medium chosen, reaches the receiver without any distortion or change. For example: --- a letter, email, text message, lecture.



How it works:

How it works In this model, the information is passed from the sender to receiver with a proper flow and a proper medium The receiver passively receives the message And then the receiver acts as directed or desired by the sender It is a one way process so there is no feedback given by receiver to sender


Drawbacks The linear model assumes that there is a clear cut beginning and end to communication. The linear models gives a one way act usually vertical, and not cyclical two way process. This model is not interactive thus it lacks mutual understanding and collective actions. In this model there is no feedback.

Shannon- Weaver Model:

Shannon- Weaver Model In 1949 by C.E Shannon and W Weaver. First to point out that message can be changed or blocked. Weaver introduced the idea of feedback. In this model feedback is not considered to be an integral part because the model conceived the communication process as a linear act and feedback as new act of communication.

Shannon-Weaver Model:

Shannon-Weaver Model Information Source Message Encoding Process Noise Source Signal Received Signal Decoding Process Message Destination Channel Feedback

How It Works:

How It Works Source creates message Sends message Selects Channel Receiver gets message Filters: *Experience *Knowledge *Feelings Interprets message Noise Feedback

Assumptions of Shannon-Weaver :

Assumptions of Shannon-Weaver Communication breakdown is caused by ‘noise’ The model is developed to separate noise from information-carrying signals e.g. electronic media (TV, radio, print), digital online media (internet, data carrying devices) The emphasis is on physical or semantic noise Physical or Semantic Noise Distraction (thunder, roaring motorbike, barking dog, snow on TV screen, static sound on the phone, smudge on the newspaper, etc) Emphasizing the wrong part of the message Attitude towards the sender Attitude towards the message

Criticisms of Shannon-Weaver Model :

Emphasis in on the transmission of message Developed to separate noise from information-carrying signals Assumes that communication is relatively unproblematic Criticisms of Shannon-Weaver Model


TWO-WAY COMMUNICATION PROCESS Communication can be seen as a two way process. In this concept the sender also acts as a receiver & vice versa . This can be experienced in case of tele marketting or in case of call centre.

Slide 16:

Two way concept of communication is more contemporary kind of. It makes communication a reciprocal process or mutual exchange process. No distinction in the role of sender & reciever . In traditional concept only the sender was the determiner of the message but now he has to contruct the message keeping in mind the perception of the reciever . This leads to common interpretation & meaning makeing the communication effective. Also this satisfies the sender as to the completion of communication.
