Games change, but parents still rule

Computer games are a blessing and a curse for parents. We know exactly where children are when playing them, but worry that what is on the screen is too violent or trivial, wastes too much time or is taking precedence over homework and physical activity. It is even more troubling when suggestions to get out of the house and meet friends or go to the park for exercise are ignored or done reluctantly; our reaction is to think of addiction and associated disorders like anxiety and depression. Then we read that gaming can improve problem-solving skills and sharpen alertness and reflexes, and we get confused.

Part of the problem is that times have changed since today's parents were growing up. Computers were not as widespread then, and typical after-school activities for us beyond watching television involved going somewhere - maybe to the shopping mall to hang out with friends, perhaps to the soccer pitch, bicycle riding or fishing. Technology is also ever changing and we may not realise that games are getting increasingly sophisticated, to the point that they are multi-player and span the world. A child sitting alone in a room is usually anything but; with a webcam and headphones, he or she can see and talk to friends, perhaps dozens of them at the same time.

Researchers disagree about whether games are good or bad. It depends on the game and how much time is spent playing it. Some studies show that they can improve minds and creativity, but others indicate links to mental health problems, and if violent images are involved they could be desensitising. It is all a matter of what to believe.

But on one issue there is no doubt: moderation. Too much of anything, whether food or computer games, is bad. It is up to parents to step in when we think that enough is enough. That may seem difficult in an online, wireless world, where the internet and games are accessible at any place and time. If our children are unable to control themselves, it is up to us to set guidelines.
