Media analysts have developed theories and explanations of how humans take in the media texts and how it may influence or our behaviour in everyday life.
The Hypodermic Needle or Hypodermic Syringe
Dating from the 1920's, this theory was the first attempt to explain how mass audiences might react to mass media. It is a crude model, as it implies that audiences receive media texts through a forceful means of injection of the mind, hence 'hypodermic needle' without any challenge or attempt at processing the data. The most famous incident of this model being in use, was the wide spread panic of the American public from the film "War of the Worlds" in which a number of people were so influenced by the film, they believed and thought the film as becoming a reality around them.
Paul Lazersfeld and Herta Herzog challenged this and based a lot of their research from this incident, and found it was in fact quite a small majority of viewers of the film that were in panic, and Hadley Cantril showed that it diverse in reaction, and were largely determined by situational and attitudinal attributes of the viewer.
Uses and Gratification
During the 1960's, as the first generation to grow up with television became grown ups, it became increasingly apparent to media theorists that audiences made choices about what they did when consuming texts. Far from being a passive mass, audiences were made up of individuals who actively consumed texts for different reasons and in different ways. In 1948 Lasswell suggested that media texts had the following functions for individuals in society:
- Surveillance
- Correlation
- Entertainment
- Cultural Transmission
The Peoples Choice
Paul Lazarsfeld, Bernard Berelson, and Hazel Gaudet analysed the voters decision making processes during a 1940 presidential election campaign and published their results in a paper called The Peoples Choice. Their findings suggested that the information unmediated but its filtered through "opinion leaders" who then communicate it to their less active associates, over whom they influence.
The audience then mediate the information received directly from the media with the ideas and thoughts expressed by the opinion leaders, thus being influenced not by a direct process, but by a two step flow. This diminished the power of the media in the eyes of researchers, and caused them to conclude that social factors were also important in the way in which audiences interpreted texts. This is sometimes referred to as the limited effects paradigm.
Reception Theory
Extending the concept of an active audience still further, in the 1980s and 1990s a lot of work has been done on the way individuals received and interpreted a text, and how their individual circumstances (Gender, class, age, ethnicity) affected their reading. This work was based on Stuart Hall's encoding/decoding model of the relationship between text and audience - the text is encoded by the producer, and decoded by the reader, and there may be major difference between two different readings of the same code.
