Communication modelsCommunication models

Linear modelsTrace a one-way flow of

messages with the speaker or sender developing or encoding a message that would be sent over a channel or channels to be received by a listener or receiver

Communication models (2)Communication models (2)

Interactional modelsTake into account critical

importance of feedback—signals or messages that tell the sender what is happening at the receiving end of the process

Shannon-Weaver model Shannon-Weaver model (cont’d)(cont’d)

• Information source produces message

• Transmitter operates on the message in some way to produce a signal suitable for transmission over the chosen channel


• Channel is the medium used to transmit the signal from the transmitter to the receiver. It can be a beam of light, a band of radio frequency, etc.


• Receiver accepts and decodes signals into information

• Destination is the person or thing for whom the message is intended

InformativenessInformativeness

• The informativeness of a message is that property which reduces uncertainty in the intended recipient . . . In other words, information is concerned with the degree of change to the knowledge state of the recipient as compared with the original state prior to the exposure to the message.

Informativeness (2)Informativeness (2)

• Information is a measure of one’s freedom of choice when one selects a message.
