Cultivation Theory
George Gerbner tried to determine the influence of television on viewers" ideas of the environment they lived in. He found that dominance of TV created a common view of the world and that it homogenized different cultures. TV portrayed the society as a bad place to live in leading to people becoming distrustful of the world. Over time, particular symbols, images, messages, meanings become dominant and are absorbed as the truth. Cultural stereotypes, ways of assessing value and hierarchies are established.
Watching television may influence viewers' ideas of what the everyday world is like. Cultivation research is in the 'effects' tradition. Cultivation theorists argue that television has long-term effects which are small, gradual, indirect but cumulative and significant.
They emphasize the effects of television viewing on the attitudes rather than the behaviour of viewers. Heavy watching of television is seen as ‘cultivating’ attitudes which are more consistent with the world of television programmes than with the everyday world. Watching television may tend to induce a general mindset about violence in the world, quite apart from any effects it might have in inducing violent behaviour.
Hypodermic Model
The theory suggests that the mass media could influence a very large group of people directly and uniformly by ‘shooting’ or ‘injecting’ them with appropriate messages designed to trigger a desired response.
Both images used to express this theory (a bullet and a needle) suggest a powerful and direct flow of information from the sender to the receiver.
The bullet theory graphically suggests that the message is a bullet, fired from the "media gun" into the viewer's "head". With similarly emotive imagery the hypodermic needle model suggests that media messages are injected straight into a passive audience which is immediately influenced by the message. They express the view that the media is a dangerous means of communicating an idea because the receiver or audience is powerless to resist the impact of the message. There is no escape from the effect of the message in these models.
The population is seen as a sitting duck. People are seen as passive and are seen as having a lot media material "shot" at them. People end up thinking what they are told because there is no other source of information.
