As we approach the time of year when students leave home without really leaving, because they remain tethered via Facebook. That makes reports of this new study a bit more interesting than it might otherwise be. (It reportedly contradicts other studies.) What I do know, just observing, is how addicted students are to Facebook as well as the regular flow of text messages from friends. They can't even enjoy a pleasant walk across a beautiful campus! But that is only half of it. It would be great to see a study of the academic effects. The big problem I see is that they cannot concentrate in class, when doing homework, and probably when writing longer papers. I see the first two cases regularly. The short distractions of "social media" simply feed their impatience with any frustration when working unsystematically on a problem. But it must be particularly bad in the teen years, seeking social approval. I saw a truly classic example the other night when marveling at one of those stories about folks prepping for the apocalypse. You should have seen the look on the teen daughter's face when she learned that her cell phone would not work in their underground bunker where they plan to hide out while crazed, hungry, armed people rampage through the city.
