     The regular use of text messages and emails can lower the IQ more than twice as much

as smoking marijuana(大麻). 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 fourpoint drop in IQ

associated with smoking marijuana, according to British researchers, who have labeled(把

……称为)the fleeting phenomenon of enhanced stupidity as "infomania"．

     The noticeable drop in IQ is believed to be the result of 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 tasks in hand.

     The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its

overall effectiveness. While modern technology can have huge benefits, excessive(过度的)use

can be damaging not only to a person's mind, but to his or her social life.

     Eighty volunteers took part in clinical trials on IQ damage and 1,100 adults were interviewed.

     More than six in ten people polled admitted that they were addicted to checking their emails

and text messages so that they examined workrelated ones even when at home or on holiday.

Half said that they always responded immediately to an email and one in five would interrupt a

meeting to do so.

     Furthermore, infomania is having a negative effect on work colleagues, increasing stress and

disagreeing feelings. Nine out of ten polled thought that colleagues who answered emails or

messages during a facetoface meeting were extremely rude. Yet one in three Britons believed

that it was not only acceptable, but actually diligent and efficient to do so.
