Is screen time bad for children’s brains?


A generation ago, parents worried about the effects of TV; before that, it was radio.

Now, the concern is “screen time”, a catchall term for the amount of time that children, especially preteens and teenagers, spend interacting with TVs, computers, smartphones, digital pads and video games.

This age group draws particular attention because screen immersion rises sharply during adolescence, and because brain development accelerates then, too, as neural networks are pruned and consolidated in the transition to adulthood.

It is probably both bad and good for the brain, depending on the individual and his or her viewing habits.
