Today, they’re so common that researchers have devoted studies to them. For Valerie Kusler, who works on a cattle farm, the feeling is complicated by the cows. “The cows’ moo is very muffled, it kinda sounds like ... errrrrr，” she says. “So thats very similar to what my phone sounds like when it vibrates on my desk or in my purse.” Other people may not confuse cows for their phones, but research shows phantom vibration symptom is a nearuniversal experience for people with smartphones. Nearly 90 percent of college undergraduates in a 2017 study said they felt phantom vibrations. The number was just as high for a survey of hospital workers, who reported feeling phantom vibrations on either a weekly or monthly basis. “Something in your brain is being triggered (触发), that’s different than what was triggered just a few short years ago，” says Dr Larry Rosen, a research psychologist who studies how technology affects our minds. “If youd asked me 10 years ago, or maybe even five years ago if I felt an itch beneath where my pocket of my jeans was, and asked me what I would do, I’d reach down and scratch it because it was probably a little itch caused by the neurons firing(神经元刺激)，”he says. Now, of course, the itch triggers him to reach for his phone. Rosen says its an example of how our devices are changing how our brains process information. |
