P: Carnagey provided evidence for the claim that playing violent computer games produces physiological desensitisation
E: participants played either a violent or non violent game for 20 minutes and then watched a 10 minute film clip containing scenes of real life violence while their heart rate and skin conductance response were monitored. those who played the violent computer game had a lower heart rate and skin conductance while viewing the filmed real life violence
L: this demonstrated a physiological desensitisation to violence, as predicted by this explanation
