So, how does it happen? Researchers believe that phantom vibration syndrome may result from a misinterpretation of incoming sensory signals by the brain. 'In order to deal with the overwhelming amount of sensory input, the brain applies filters based on what it expects to find. In the case of phantom vibrations, because the brain is anticipating a call, it misinterprets sensory input'. The actual stimulus for this sensation could be the pressure from clothing, muscle contractions, or other sensory stimuli.

那么，这一状况究竟如何发生的呢？研究者认为，可能是因为大脑对所接收的感官信号产生了误读。“为了处理接受到的海量的感官信号，大脑根据自己的需求来进行筛选。在手机震动错觉中，就是因为大脑希望接到电话，所以误读了接收到的信号。”而诱发这一错觉的信号可能是服装对身体的压迫感，肌肉的震颤，或其他感官信号。

But it is still not known why some experience PVS while others don't or why some body locations are more PVS-prone than others. What is obvious is that younger generations are more susceptible to PVS. One theory is that neural plasticity (the brain's ability to reorganize itself by forming new neural connections) of younger people makes them more susceptible to imagine vibrations.

但是这还是不能解释为什么有的人或者有的情况下PVS更容易发生。比较显著的是年轻人更容易感受到这种错觉。一种理论是年轻人的神经可塑性(大脑通过构建新的神经元联系来进行重塑的能力)更强，因此也更容易产生震动错觉。
