Explaining the Communication Process through Models
To understand better the process of communication, here are some
models as discussed by communication scholar Denis McQuail (2005) in
his book McQuail‘s Mass Communication Theory:
1. Transmission models. Perhaps the most popular among these is
Harold Laswell‘s representation of communication as an attempt to
answer the question ―Who says what to whom, through what
medium, and with what effect?‖
Fig. 1.1. Laswell's Communication Model
The model is relatively straightforward and tells you that communication
originates from someone and their message flows through a channel,
either through sound waves or light waves, and that someone on the other
end receives the message with a corresponding effect. Later
improvements in the model were introduced by other experts in
communication. One such revision is a model by Claude Shannon and
Warren Weaver which incorporates the concept of noise that refers to
anything that interferes with the message. The model is a more
mechanical look at communication. 2
