Negative effects of video games

1. 
   Aggressiveness: children are increasingly exposed to growing physical and sexual violence present in all media. The violent content of these media may cause childhood aggression (Anderson 2007).
   
2. 
   Violence and pornography: video games such as “Grand Thief Auto” and “Call of Duty” for over 18 years, are training children to shoot and kill in a virtual world in which the values ​​of life are lost.
   

Online multiplayer games are not recommended for children under 13 years because it is in this environment where unhealthy habits (rudeness, bullying , addiction, pornography ) develop, says Andrew Doan, medical PhD, author of “Hooked on Games”.

3. 
   Attention problems: high speed media content can contribute to attention deficit disorder, as well as decreased concentration and memory (Christakis 2004 , Small 2008). Elementary school children who play video games more than two hours a day were 67 % more likely to develop attention problems, according to a study published in Pediatrics magazine.
   
4. 
   Impatience: “New technologies make us more impatient and decrease frustration tolerance. They also relax a part of our brain that has to be worked”, said Alvaro Bilbao, neuropsychologist.
   
5. 
   Addiction: the player’s immediate response to stimuli game generates a mini-reward in the form of release of dopamine (pleasure hormone).
   

These rewards are small injections of energy feeding the engine of compulsion and continuously create a powerful effect, says Dr. Judith Donat (MIT).

6. 
   Sleep Deprivation: Exceeding exposure to entertainment screens produces sleep problems. Day and night overexposure generates (very vivid) hypnagogic images that usually produce nightmares.
   
7. 
   Emission of radiation: in May 2011 , the World Health Organization classified mobile phones and other wireless devices as a class 2B risk (possible carcinogen) due to the emission of electromagnetic radiation.
   

These are the main advantages and disadvantages of video games. Again:
What matters is the relationship that the child establishes with the technology under adult supervision.
