The very fact that these children play these games for eight hours over a brief time period is alarming as it means that these children are becoming more and more desensitized to violent acts.
Recent studies carried out showed children who played these games had higher tendencies of physiological arousal. Symptoms such as heart rate and blood pressure all increased as the children got caught up with the excitement and ferocity of these games. (Van & Weigman 1997)A famous computer games around; Mortal Combat, was involved in an experiment in which the heart rate was measured without the option of “blood” being turned on and then it being turned off. It was proven, that when in fact the blood option was on, the resulting heart rate was much greater. (Kirsh 1998)
