In many scientific and technological products, smart phones control the user's attention to an unprecedented extent, and it also has a huge impact on our thinking and behavior. So what influence does it have on our mind when we allow a single tool to have such a high degree of control over our own opinions and perceptions? Scientists have begun to explore this problem. Our mobile phones not only shape our minds in a profound and complex way, but even when we don't use mobile phones, that's going on.Research showsAs the brain becomes more dependent on technology, intelligence is weakened accordingly. More and more evidence suggests that the use of smart phones, or even just hearing the ringing or shaking of the phone, will distract attention and cause people to concentrate on a difficult problem or work harder. Distraction is a hindrance to people's reasoning ability and performance.
