A Chicago-based psychiatrist, Dr. Kourosh Dini, has written a definitive book called Video Game Play and Addiction: A Guide for Parents.
Dr. Dini, a long-time gamer, writes this comprehensive book with great understanding, as well as empathy -- showcasing both viewpoints of the controversy that is video games' effects -- physical and emotional health, educational and social development of a child.
He believes that parents don't always know what is an age-appropriate game for their child to be playing. Whereas one that are appropriate "[multi-player video] games can allow children to learn how other people think -- a key aspect of empathy. Games can also help a child become more comfortable with new and ever progressing technology."
"Video Game Play and Addiction" also hits upon different game genres and how video games can improve learning and communication skills, effect emotional and mental health, and have adverse affects, as well -- like aggression, motivational and withdrawal issues.
While the media has always been rash in categorically dismissing and criticizing the addictive dangers of extended video game play, we know that the American Medical Association (AMA) doesn't want to label video game addiction as a mental illness, as it believes more study and research is warranted to make that claim.
However, Dr. Dini does give a sweeping view of "problematic game play" and its warning signs, and causes and consequences for children. He also does a great job of explaining the Entertainment Software Rating Board (ESRB) various ratings, simplifying it so that parents can understand what constitutes as age appropriate when they are purchasing games for their children.
While this book may be written for parents, media, legislators and medical professionals, it's a great resource for anyone who wants to learn more about what is, and how we can maintain a level of responsibility to our children to enjoy games in a "responsible, safe, stimulating and fun" manner.
