The addictive nature of social media has gained public attention and fear of its power to create mental disorders. Two reasons seem to underlie this concern: the widespread lack of knowledge of child psychological development; and public reluctance to confront parenting errors which I consider the proverbial Elephant in the Room.
That web activity can be addictive is undeniable but so are other activities which are obsessive-compulsive in nature since it is part of the human condition: an inborn mental mechanism designed to reduce anxiety which is its lure. An obsession is a recurring thought and a compulsion is a repeated behavior. For example, frequently worrying whether one has locked a door (the obsession) may cause the person to check this several times (the compulsion).
So when a youth is greatly involved in any such activity, video game play, web viewing, hopscotch or anything else, it indicates their excessive anxiety and need for parental and possibly professional investigation of why they are distressed rather than parental obsessing about what they are doing (unless it is potentially harmful or dangerous, of course).
As New York City's past mayor observed when an armed teenager was arrested while wandering the streets at night: where were his parents when he was behaving like this?
