Psychologist Dr Aric Sigman has caused controversy by saying that under-three's should have almost no exposure to television. While it would be difficult to argue the opposite, many may be surprised that Dr. Sigman recommends virtual banishment for the very young. Furthermore, he recommends limiting up-to-seven year olds to a maximum of an hour and a half of TV or computer exposure per day, and a maximum of two hours up to the age of 18.
Dr. Sigman's recommendations are based on a number of research observations. One concern is that sitting in front of screens leads to a sedentary lifestyle and is largely responsible for the explosion in diabetes and heart disease in the population. Another concern is that the acts of watching television and playing computer games have an affect on brain development. While brain scans of computer gamers showed different brain patterns, his research does not conclusively prove that gaming alters the brain, or whether people with gaming patterns are predisposed to playing games. His research does suggest that gamers are more prone to addiction and develop a dependency on screen technology.
We probably aren't that surprised to hear all of this; we all remember our own grandparents talking about the perils of television and the harm it would do in modern society, but back then it was pure conjecture and fear of the unknown. That their fears are being realised at a time when screens are appearing in every room of the house and even in our pockets gives us more to think about. We really have entered the information age, and we don't know where this is going!
