When Gretchen Baxter gets home from work as a New York City book editor, she checks her Blackberry at the door. “I think we are attached to these devices in a way that is not always positive,” says Baxter, who’d rather focus at home on her husband and 12-year-old daughter. “It’s there and it beckons(召唤). That’s human nature (but)…we kind of get crazy sometimes and we don’t know where it should stop.”

Americans are connected at unprecedented(前所未有的) levels—93% now use cell phones or wireless devices; one third of those are “smart phones” that allow users to browse the web and check e-mails, among other things. The benefits are obvious: checking messages on the road, staying in touch with friends and family, efficiently using time once spent waiting around. The downside: often, we’re effectively disconnecting from those in the same room.

That’s why, despite all the technology that makes communicating easier than ever, 2010 was the year we stopped talking to one another. From texting at dinner to posting on Facebook from work or checking e-mails while on a date, the connectivity revolution is creating a lot of divided attention, not to mention social anxiety. Many analysts say it’s time to step back and reassess (再评价).

“What we’re going to see in the future is new opportunities for people to be plugged in and connected like never before,” says Scott Campbell. “It can be a good thing, but I also see new ways the traditional social construction is getting somewhat torn apart.”

Our days are filled with beeps and pings—many of which pull us away from tasks at hand or face-to-face conversations. We may feel that the distractions(干扰) are too much, but we can’t seem to stop posting, texting or surfing. “We’re going through a period of adjustment and rebalancing, ” says Sherry Turkle and she wants to remind people that technology can be turned off. “Our human purposes are to really have connections with people,” she says. “We have to reclaim it. It’s not going to take place by itself.”
