French neuroscientist Michel Desmurget, in his book “The Digital Cretin Factory,” explores how digital devices are negatively affecting the mental development of children and teenagers. According to him, the primary reason today’s generation is less intelligent than their parents is due to the amount of time spent on screens.
Effects of Screens on the Brain
In an interview with BBC News Mundo, Desmurget explained how screen time impacts the development of different parts of the brain in children. The brain’s development relies on experiences and the environment, and spending too much time on screens for entertainment purposes delays the development of areas related to language and attention.
Essential Mental Activities
Desmurget emphasized that activities like studying, music, art, sports, and intellectual work are crucial for the healthy development of the brain. Time spent in front of screens replaces these essential activities, weakening brain development.
Harmful Effects of Different Types of Screens
Desmurget pointed out that not all screens are equally harmful. Using computers and the internet for educational purposes can be beneficial, provided it is part of a structured educational plan. However, when screens are used for entertainment, the negative effects are more pronounced. The most harmful uses are watching television, playing video games (especially action and violent ones), and using social media.
Average Screen Time Duration
According to Desmurget, two-year-old children spend approximately three hours a day in front of screens, eight-year-olds spend around five hours, and teenagers spend more than seven hours. By the age of 18, children have spent as much time in front of screens as a full-time worker spends in 16 years. This is both insane and irresponsible.
Conclusion
Michel Desmurget’s research indicates that digital devices and screen time are severely impacting the mental development of children and teenagers, making today’s generation less intelligent than their parents. Furthermore, excessive screen time is taking the place of educational and intellectual activities, which are necessary for healthy brain development.
Desmurget’s findings highlight the urgent need for parents, educators, and policymakers to rethink how children and teenagers engage with digital devices. Limiting screen time and encouraging activities that promote intellectual growth are crucial steps in ensuring that the upcoming generation can reach their full potential.
