Too much time spent playing video games may lead to impulsive behavior and attention problems in children, and vice versa. In other words, people who spend more time playing video games subsequently have more attention problems, and "individuals who are more impulsive or have more attention problems subsequently spend more time playing video games". This is an important finding because most research on attention problems has focused on biological and genetic factors rather than on environmental factors and now scientists have more reasons and hence are able to explain and examine the problem in a deeper way.
Maybe the problem is too much aggravated? Most people simply want to blow off steam through video games. Anyway it's better than venting one's spleen upon relatives or colleagues. So perhaps this harmless and I should say rather natural tendency doesn't have anything to do with attention and our mind on the whole? Let's take things easy...)
