Desitisation - When people observe the results of extreme aggression, they usually experience feelings of disgust and anxiety. However, repeated exposure to aggression, desensitises, reducing the strong reaction, potentially making it easier for people to be aggressive
Disinhibition - ~people often have a strong desire not to be aggressive so aggressive acts are inhibited. This inhibitions comes from socialisation, what we are taught from a young age. However, repeated exposure to justified aggression in the media, and from committing aggressive acts in computer games is thought to disinhibit the avoidance of aggression in real life
Cognitive priming - We have mntal scripts, schemes for how to respond in certain sitautions. We can learn schemas from tv and computer games. We may see hero's acting aggressively when threatened with a gun or knife and these become cues or priming stimuli. We are then cognitively primed when exposed to these cues in real life to act in a similar manner
