A study sponsored by the National Institutes of Health released in December 2018 found that kids who spent on average more than 7 hours a day in front of their screens had a thinning in the outer layer of the cerebral cortex. The thinning in the cerebral cortex has been associated with lower “crystalized” intelligence, which refers to the accumulation of knowledge, facts, and skills that are acquired throughout life, such as reading comprehension and vocabulary.
This region of the brain is responsible for executive functioning, which deals with our higher order thinking, i.e., data consolidation, problem-solving and planning. It also helps us regulate our impulses and emotions. It is among the last areas of the brain to fully mature. So it’s vital that parents help their children make healthy choices regarding the media they consume and the amount of time they spend consuming it.
Because of the pervasiveness of today’s technology, enacting tech rules on kids can be a challenge for many parents. Fortunately, they are not alone. Partnering with the school's technology coaches, Concordia administrators recently hosted a screening of the celebrated educational documentary, Screenagers, in which filmmaker and physician Dr. Delaney Ruston reveals the negative effects too much screen time has on children. The film seeks to increase understanding and inspire communities to work together to better manage screen time in our homes and schools. Talking openly about solutions gives parents the confidence to set appropriate tech limits.
Screenagers emerged directly from Dr. Ruston’s own experience with the challenge of “raising teenagers whose attention was increasingly consumed by screen-based activities.” As a physician, she was curious to know how our new tech world was affecting the development of our children. Researching the impact of video gaming and social media on self-esteem, social skills and academics, she began to understand the necessity of better managing her teenagers’ screen time.
Our new lives with kids and tech is challenging and we can’t always know if we’re parenting the “right” way, says Ruston. “But I can know that I am parenting with integrity…by following my belief that I have a responsibility to provide my kids with the most diverse type of experiences as possible.”
