Communication Theory

In this first lecture some basic facts about Communication were introduced to our little minds. In order to obtain the necessary base to start talking about Communication in a deeper way, we saw the cientific basis in which Communication began to be reproduced in. In this terms, we talked about the different Models of Communication in history.

Shannon & Weaver Model (1948):

According to Shannon and Weaver's model (as seen above), a message begins at an information source, which is relayed through a transmitter, and then sent via a signal towards the receiver. But before it reaches the receiver, the message must go through noise (sources of interference). Finally, the receiver must convey the message to its destination.

Advantages

This Model had some advantages like simplicity, generality, or quantifiability, which made it attractive to several academic disciplines. It also drew serious academic attention to human communication, leading to further theory and research.

Weaknesses

However, this model needs some reframing when it comes to the study of media and and communication, since it leaves a lot of issues outside.

Lasswell Model (1948):

This model was the enriching of the Shannon & Weaver Model. It states that a good way to describe an act of communication is to answer the following questions:

• Who

• Says What

• In Which Channel

• To Whom

• With what effect?

Jacobson´s Paradigm (1963):

Jakobson's model of the functions of language distinguishes six elements, or factors of communication, that are necessary for communication to occur: (1) context, (2) addresser (sender), (3) addressee (receiver), (4) contact, (5) common code and (6) message. This model states that we can use the same code but in different context.
