The latest research shows that playing violent computer games more often may reduce the sensitivity of the brain to violence.
The researcher selected 30 boys aged 13 to 15 years old, and divided them into two groups, one group of boys who need to play violent games for more than three hours a night, another group of boys can only play violent games less than an hour every night. Then researchers will track and compared two groups of boys in the game and their response after two hours.
The study result was published in May, "The journal of psychosomatic medicine biological behavioral medicine", which says that the group that often playing violent computer games are all with a badly sleep quality, and their heart rate are faster than others, which reflected that they are very anxious. While the other group of boys, after playing violent games, will increase their own sadness.
Researchers at the University of Stockholm, Sweden, Malena Ivarsson said that violent games bring more pressure to the players, and make them feel very nervous, and then affect the sleep. And the difference in two groups of boy’s may prove that violent games produced "desensitization effect" to the people.
