Why texting harms your IQ
The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 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 described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.
It is concluded that too much use of modern technology can damage a person’s mind. It can cause a 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. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.
Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.
The effects on IQ were studied by Dr Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

的功能成了建筑被突出强调的社会功能。历代都有相应的规制法典，对城制等级、组群等级、间架做法等级、装修装饰等级都有着严格的规定。例如《礼记.冬官考工记》中将城市分为天子的王城、诸侯的国都和宗室与卿大夫的都城三个级别，规定王城的城墙高九雉（每雉为一丈），诸侯城楼高七雉，而都城城楼只能高五雉。 《礼记.礼器》中讲:“礼有以多为贵者。天子七庙，诸侯五，大夫三，士一。”“有以高为贵者。天子之堂九尺，诸侯七尺，大夫五尺，士三尺。”唐朝的《营缮令》中规定:都城每座城门可以开三个门洞，大州的城正门开两个门洞，而县城的门只能开一个门洞。在中国古代建筑中，“间”指的是房屋的宽度，两根立柱中间算一间，间数越多面宽越大。“架”指的是房屋的深度，架数越多，房屋越深。《明会典》中规定:公侯，前厅七间或五间，中堂七间，后堂七间；一品、二品官，厅堂五间九架；三品至五品官，后堂五间七架；六品至九品官，厅堂三间七架。等级制对内外檐装修、屋顶瓦兽、梁枋彩绘、庭院室内陈设也都有严格规定。甚至对门上的零件——门环也硬性规定了铜环、锡环、铁环三级，按等级采用。对建筑物的装饰色彩也有等级划分，总的说以黄色为尊，其下依次为:赤、绿、青、蓝、黑、灰。宫殿用金、黄、赤色调，而民居却只能用黑、灰白为墙面及屋顶色调。
楼只能高五雉。
