ncrease in violent crimes, but does not take any other factors into account.
Albert Bandura applied the Social Learning Theory to aggression and television violence: what people see, they tend to imitate. He found that children learn to be aggressive by observing and imitating other people who are acting aggressively; "if these individuals are rewarded for their violent behaviour, children are even more likely to imitate them".
This statement was supported by a series of studies conducted by Bandura et al. They allowed children to view an adult acting aggressively towards a bobo doll. The children were then too allowed to play with the bobo doll. The findings showed that the children who had witnessed the violent behaviour also behaved more aggressively towards the bobo doll, whereas the children who had not witnessed any aggressive behaviour played with it in a normal fashion.
However, the findings from these studies cannot be generalised to fully support the media-aggression theory, as the events in the study are not realistic to everyday viewing television or films. Additionally, the behaviour observed has little to do with realistic attacks on other people.
A further study found that "when children are put into a group exposed to a televised 'Power Rangers' episode, they committed seven times more aggressive acts in a subsequent play period than did the control group" (Boyatzis, 1995). It is also important to note that even children who are not particularly aggressive to begin with became more aggressive as the result of television violence.
Pennsylvania State University conducted a study where 100 pre-school children were observed both before and after watching television; some watched cartoons that had a lot of aggressive and violent acts in them, and the others watched shows that didn't have any kind of violence. The researchers noticed differences between the children who watched th...
