Why? It might have to do with what the phone represents. It's a symbol of your "larger personal network," doctoral candidate John Hunter said. It may represent all the people you'd like to reach out to when you're feeling isolated. It might not matter that the people in front of you are being inconsiderate when all your phone contacts and Facebook friends are sitting in your pocket. And while there is an argument to be made for people losing their connection to the moment by staring at their phone screens, the researchers believe this mobile blankie can be helpful by offering a "sense of security" you wouldn't otherwise have.

The study wasn't a completely comprehensive one, with 148 participants and a mean age just over 20 years old. Older people who didn't grow up with smartphones might have a different response. If this is at all close to the mark, though, you might want to keep your phone close by the next time you're talking to new coworkers or classmates.
