Screen Test: The Danger of Digital Fixation


When it comes to the dangers of the digital age, most parents worry about what is on the screen of the computer. Recent research indicates that the screen itself just might be a very real danger.

Writing in The New York Times, physician Perri Klass warns that many parents are unaware of the risks posed by the digital screen. She tells of parents who tell the pediatrician that their child cannot have attention problems because he can watch a digital screen for hours on end. The child may have attention issues elsewhere, but not in front of a screen.

Dr. Klass writes:

In fact, a child’s ability to stay focused on a screen, though not anywhere else, is actually characteristic of attention deficit hyperactivity disorder. There are complex behavioral and neurological connections linking screens and attention, and many experts believe that these children do spend more time playing video games and watching television than their peers.

Dr. Christopher Lucas of the New York University School of Medicine explains that the kind of attention demanded by the digital screen is very different from that required, for example, by a classroom or a book. The child in the classroom has to pay attention without immediate reward and learn to maintain that attention. When reading, a child has to supply the reward by means of imagination.

But, when focused on a digital screen, the child’s attention is rewarded by “frequent intermittent rewards” in the form of hormones released into the brain. The child may grow dependent on these rewards and lose the ability to maintain attentiveness without the pleasurable charges to the brain.
