Screens like tablets and phones have a huge impact on the growing brain of a child. At young ages, their brains need real experiences in order to develop properly but screens do change that “MRI scans found significant differences in the brains of some children who reported using smartphones, tablets, and video games more than seven hours a day.”Children who reported more than two hours a day of screen time got lower scores on thinking and language tests.” This proves that screens have negative effects on the brain while being used over long periods of time. It’s changing their way of thinking because they have so much access to the screens, by making them lazy and not prompting them to learn real things.
