手機，電腦已經成為我們工作和生活的必需品。然而，這些高科技的產品帶給我們的不一定只有福利。心理學家發現，使用手機或敲擊電腦鍵盤發送或接收電子信息會暫時降低使用者約十個百分點的智商。

The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana.

That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ.

This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled the fleeting phenomenon of enhanced stupidity as “infomania”.

Research on sleep deprivation suggests that the IQ drop caused by electronic obsession is also equivalent to a wakeful night.

Infomania is mainly a problem for adult workers, especially men, the study commissioned by Hewlett Packard, the technology company, has concluded.

The noticeable drop in IQ is attributed to the constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand.

Workers lose productivity by interrupting a business meeting and disrupt social gatherings because of their infirmity, the report said.

The brain also finds it hard to cope with juggling lots of tasks at once, reducing its overall effectiveness, it added. And while modern technology can have huge benefits, excessive use can be damaging not only to a person’s mind, but to their social life.

Furthermore, infomania is having a negative effect on work colleagues, increasing stress and dissenting feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believes that it is not only acceptable, but actually diligent and efficient to do so.

The effects on IQ were studied by Dr Glenn Wilson, a University of London psychologist, as part of the research project. “This is a very real and widespread phenomenon,” he said. “We have found that infomania, if unchecked, will damage a worker’s performance by reducing their mental sharpness. Companies should encourage a more balanced and appropriate way of working.”
