Most of us experience false alarms with phones, because it is a common and unavoidable part of healthy brain function.
Sensing phantom (错觉的) phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it’s actually completely still. Almost 30% of us have also heard non-existent ringing. Are these hallucinations (幻觉) ominous (不祥的) signs of impending madness caused by digital culture?
Not at all. In fact, phantom vibrations and ringing illustrate a fundamental principle in psychology.
It’s an example of a perceptual system, just like a fire alarm, an automatic door, or a daffodil bulb that must decide when spring has truly started. Your brain has to make a perceptual judgment about whether the phone in your pocket is really vibrating. And,
analogous to
a daffodil bulb on a warm February morning, it has to decide whether the incoming signals from the skin near your pocket indicate a true change in the world.
Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Analyzing the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function.
When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn’t. Obviously you’d like to match these states in the correct way. True vibrations should go with "it’s ringing", and no vibrations should go with "it’s not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection", respectively.
But there are two other possible combinations: you could mismatch true vibrations with "it’s not ringing" (a "miss"); or mismatch the absence of vibrations with "it’s ringing" (a "false alarm"). This second kind of mismatch is what’s going on when you imagine a phantom phone vibration.
For situations where easy judgments can be made, such as deciding if someone says your name in a quiet room, you will probably make perfect matches every time. But when judgments are more difficult—if you have to decide whether someone says your name in a noisy room, or have to evaluate something you’re not skilled at—mismatches will occasionally happen. And these mistakes will be either misses or false alarms.
The experience of sensing phantom phone vibrations is________.
选项
A、an avoidable problem of brain function
B、a common brain problem
C、a sign of impending madness
D、a normal brain function
答案
D
解析
细节题。根据题干中的sensing phantom phone vibrations定位到文章前两段。由第一段it is a common and unavoidable part of healthy brain function可知经历手机带来的假警报是健康大脑功能最常见、最不可避免的一部分,同时,第二段最后一句和第三段第一句指出这种幻觉绝不是即将神经错乱的预兆,由此可知,感到手机振动的幻觉是一种正常的大脑功能,故选D。
