children from low-income families spend more time handling technology -- across platforms -- than their wealthier counterparts, and across class, kids mainly use their "handling skills" for entertainment. They play games, watch videos, and visit social networking sites.

there's scant evidence that anyone but the companies who make, sell, and advertise on these new technologies benefit from the time young children spend with them, there's plenty of reason to be worried about it.

studies showing that the bells and whistles of electronic books actually detract from reading comprehension.

I'm worried that screen-based reading, with omnipresent hyperlinks, interferes with comprehension and memory, and that heavy Internet use appears to encourage distractedness and discourage deep thinking, empathy, and emotion.

fast-paced video games trigger dopamine squirts in our brains -- kind of like cocaine.

here's what worries me most: We're turning to the companies that profit from these technologies to help parents manage their kids' relationship with screens. While it's great that the Federal Communications Commission is launching a campaign to promote digital literacy, the fact that companies like Best Buy and Microsoft are funding it make it unlikely that weaning kids from their products will be a priority.

the skills they will always need to thrive -- deep thinking, the ability to differentiate fact from hype, creativity, self-regulation, empathy, and self-reflection -- aren't learned in front of screens. They are learned through face-to-face communication, hands-on exploration of the world, opportunities for thoughtful reflection, and dreams.
