不时要摸摸兜里的手机振了没？但拿出来看又发现并没振过，这是不是患上了强迫症？这种误解是源于大脑错误诠释轻微的肌肉痉挛。别担心，这不是幻听或幻觉，而是一种文明病，心理学将它称之为"信号发觉"(signal detection theory)，也可以称之为“幻觉振动综合症”(phantom vibration syndrome)。
Do you ever think your mobile phone is ringing or vibrating when it's not? That's called "phantom vibration syndrome."
你曾经听到手机铃声响起，或感到手机在振动，事后又发现没有么？这被称之为“幻觉振动综合症”。
Phantom vibration syndrome isn't really harmful -- in the study of college students, more than 90 percent said they considered phantom vibrations to be "only a little" or "not at all" bothersome.
“幻觉振动综合症”不见得有害，在针对大学生的一项调查中，超过90%的受访者认为这“仅有一点儿”或者“根本不”让自己烦恼。
But some believe it's a warning sign that too much technology may be hazardous to human interaction.
但也有些人认为，这提醒人们，过多的依赖科技或许对人们之间的交流有坏处。
