Do you ever pull your phone out of your pocket，thinking it is vibrating（振动），only to find that it isnˈt？This phenomenon，which scientists call"phantom（幻觉的）phone vibration"，is very common. Around 80% of people surveyed say they have imagined their phones vibrating when they were actually still.
So，what leads to this universal behavior？According to the BBC，the explanation lies in your brainˈs ability to discover signals from the outside world. When your phone is in your pocket，there are two possible states：it is either vibrating or not. Meanwhile，you also have two possible states of mind：the judgment that the phone is vibrating，or that it isnˈt. Ideally，you match the four states correctly.
However，sometimes your brain decides that the results of missing a call are more serious than a"false alarm". Therefore，you become more sensitive（敏感的） to vibrations so that you donˈt miss anything. This is just like the fire alarm in your home---it can be annoying when it goes off in response to just a tiny bit of smoke. But thatˈs a small price to pay compared to a fire really breaking out because the alarm fails to alert you. Now，you might still ask：why canˈt our brains just make every judgment correctly without being too sensitive to false signals？The answer is that your brain bears a heavy burden every day. "You get a large amount of sensory(感觉的) information thatˈs coming from your eyes，ears and skin，and you canˈt deal with all that information all the time，"Michael Rothberg，a researcher at Baystate Medical Center in Springfield，US，told Live Science.
For example，the rustling（沙沙声）of clothing or the growling（咕咕声）of your stomach may both lead your brain to believe that they come from the vibration of your phone-it is like trying to hear your name being called in a noisy room.
So，perhaps you should just check your phone whenever you think itˈs vibrating. Itˈs not too much trouble to do that，is it？

B. We should just check our phones whenever we think theyˈre vibrating.
C. We should ignore the vibration bothering when our phones are actually still.
