This theory believes that audiences are 'injected' with ideas, attitudes and beliefs. this theory is mostly used to describe children when they behave violently or inappropriately after watching violence on TV or at the cinema. Also children can become violent after playing video games over a period of time.
Lots of people have been affected by this and have committed crimes because of it. For example at a cinema showing of the new Batman film near Denver Colorado, where 12 people were killed and 59 wounded after a man dressed as the joker from the last film shot the people. He open fired during an action scene in the film. This reenforces the theory as from watching the other Batman films he was injected with attitudes of the villain in the Batman film.
I think that my AS film opening uses this theory as it gives the idea to women that when they are alone walking at night that they need to wary of the dangers around them like someone stalking them. By this attitude being injected into the audience it will make people more wary and will keep women of all ages safer in the future.
