Theory/Model

Desensitisation:-
This theory suggests that the audience's attitudes to violence can be affected by having been exposed to too much violence on screen.
Exposure too too much fictional violence is argued to amount the audience being 'desentisitised' to real life violence.

Strengths:-
It draws attention to the sheer volume of violence onscreen and raises questions about the degree of exposure audiences should have to violent and aggressive images.

Weaknesses:-
It is extremely difficult to prove how attitudes may have been affected by the single stimulus of medi. There may be many other variables involved.
