Communication Theories: Shannon, Lasswell and Eco
Fichas del conjunto (3)
- 1MATHEMATICAL THEORY (Shannon and Weaver model)Its aim is to control the efficiency in the transmission of information with the emphasis on the contents being a lineal, vertical, authoritarian, traditional, unidirectional (one-way), informative, transmissive, and rigid communicative model, where a sender presents an idea to a passive receiver with no direct feedback.
- 2Funcionalist Theory (Laswell)LasweII is considered to be the maximum referent who raised the study of communication from his questions "Who says what, through which channel, to whom and with what effect?" The sender only controls the message and its distribution, but not its interpretation on or reception.
- 3Semiotic Theory (Eco)It goes around the concept of coding and decoding from the receiver, as well as the importance of the context and the relationships between the sender and the receiver for the correct interpretation of the message. This theory corresponds to a two-way model (bidirectional) where there is a sender that transmits a message through a channel to a receiver, which receives this information and responds by sending a negative feedback. According to Kaplun (1988), the main purpose is to persuade, control and manipulate the receiver's behavior. It emphasizes on the effects. Aparici (2010) calls this communicative model as "false democracy", as that feedback is confused with participation.
