Desensitisation is a word used to describe the ways in which viewing acts of violence reduce our responsiveness (Bushman & Huesmann, 2006). Media violence may stimulate aggressive behaviour by desensitising children to the effects of violence. This means that the more violence that a child views on television, the less emotionally concerned they become and the more acceptable it seems (Cline, Croft & Courrier, 1973). Frequent viewing may cause children to be less anxious about violence and see it as more ‘normal’. Therefore, they may be more likely to engage in violence themselves.
According to Browne and Hamilton-Giachritsis (2005), there is consistent evidence that violent imagery in television, film and computer games has substantial short-term effects on arousal, thoughts, and emotions. This increases the likelihood of aggressive or fearful behaviour in younger children, especially boys. These conclusions were drawn after a search for published work was conducted, revealing five meta-analytic reviews and one quasi-systematic review, all of which were from North America. The evidence becomes inconsistent when considering older children and adolescents, and also the long-term effects upon all ages. The different levels of aggression in children were tested, resulting in difficulties with the method and problems showing causation. However, a small but significant association was found, but with only weak evidence from correlation studies that linked media violence to crime.
Disinhibition is quite similar to desensitisation, the promoting of violent behaviour leads us to believe that violence is common and acceptable. According to Suler (2005), this reduces our normal inhibitions about behaving in certain anti-social ways, and may lead to us stopping exerting conscious control over our behaviour. Josephson (1987) argues that violence on screen is very different to violence in the real world, stating that media violence is more likely to make children more ‘frightened’ than ‘frightening’. According to Huesmann and Moise (2003), there are stronger desensitisation effects for males than there are for females. They suggest that boys who watch excessive amounts of television show lower-than-average physiological arousal in response to scenes of violence.
There is not sufficient evidence to support the claim that the media desensitizes children to violence, as there is an unpredictable link between watching television and aggression. The media cannot be wholly blamed for causing desensitization and disinhibition efftecs, certain factors such as individual differences and personality types need to be taken into consideration. Results cannot be generalizable to all children, as most studies tend to be conducted on young, white males, without taking into consideration females or other cultures. There are also some methodological problems; demand characteristics are common with controlled experiments. For example, when a natural experiment was conducted in St Helena (a British Colony in the South Atlantic Ocean), where people were first introduced to televisions in 1995, the new televisions did not increase aggressive behaviour, or desensitize people to acts of aggression (Charlton & O’Bey, 1997).
