(Original title: Popular science: the mobile phone will affect the brain's cognitive function)
Xinhua News Agency, Beijing, July 8th. Do you leave your mobile phone for 24 hours? Researchers recently discovered that when smart phones are within easy reach, even if they are turned off, they can affect the cognitive ability of the brain.
To test the extent of this effect, researchers at the University of Texas at Austin campus conducted a series of experiments on nearly 800 smart phone users.
In one experiment, the researchers asked the respondents to complete a set of questions in front of the computer that required high concentration to achieve high scores to assess their effective cognitive ability, that is, the brain to obtain and process data within a specified time Ability. Before the test, the participants needed to mute the smartphone and were randomly asked to put their phone in their pocket or bag, face down on the table, or in another room.
The results showed that people who put the phone in another room performed significantly better than those who placed the phone on the table and were slightly better than those who put the phone in the bag. The researchers said that a linear trend can be observed in this experiment, that is, the more prominent the position of the mobile phone, the lower the person's effective cognitive ability.
Researchers believe that as long as the phone is within sight or within reach, it will cause people to lose their attention. It is not the mobile phone's push or notification that distracts people's attention. Instead, people subconsciously do not "consider" the mobile phone, but the process of issuing this instruction by itself will consume limited cognitive resources and cause brain drain.
Therefore, as long as the mobile phone is around, it will reduce people's cognitive ability.
