• there are methodological problems in studying media influences for aggression, for instance, livingstone (1996) found most research is American and has used unrepresentative samples such as male students, limiting the generalisability of findings supporting media influences on aggression
• Ferguson et al (2009) claim that research rarely controls for variables that increase aggression
• artificial measures of aggressive behaviour such as delivery noise blasts two other participants are typically used as the dependent variable, this does not reflect real life aggression and how the media influences it, lacks eco validity, criticises anderson and dill
