[Media and children's well-being].

Watching television, video and computer games, and internet constitute a significant part of children's leisure time. High media exposure, however, increases the risk of psychosocial symptoms in children, such as aggressions, difficulties of behavioral regulation and concentration. In particular, media violence is thought to be harmful for children's well-being.
