单选题 Poverty and the all-consuming worry that comes with it require so much mental energy that the poor have little brain power left to devote to other areas of life, according to the findings of an international study published on Thursday. Harvard economist SendhilMullainathan finds that the mental strain could be costing poor people up to 13 IQ (Intelligence Quotient) points, which means they are more likely to make mistakes and bad decisions that increase and keep their financial worries. 'The results suggest that when you are poor, money is not the only thing in short supply. Cognitive (认知的)capacity is also stretched thin,' he said. In a series of experiments, researchers from Harvard, Princeton and other universities in North America and from Britain's University of Warwick found that urgent financial worries had an immediate impact on poor people's ability to perform well in cognitive and logic tests. Far from signaling that poor people are stupid, the results suggest those living on a tight budget have their effective brain power, or what the researchers called 'mental bandwidth,' highly limited by the stress of making ends meet. On average, someone weighed down by money worries showed a drop in cognitive function in one part of the study that was comparable to a 13-point drop in IQ, and similar to the performance deficit expected from someone who has missed a whole night's sleep. 'Previous views of poverty have blamed it on personal failings, on an environment that is not helpful to success,' said Jiaying Zhao, an assistant professor of psychology. 'We are arguing that the lack of financial resources itself can lead to less active cognitive function,' she said. Professor EldarShafir said it was not stress in general, but financial worries in particular, that led to a reduced ability to make sound decisions. 'The poor are often highly effective at focusing on and dealing with urgent problems,' he said. 'But they don't have leftover bandwidth to devote to other tasks. So, if you live in poverty, you're more likely to make errors and errors cost you more dearly—it's hard to find a way out.'

单选题 They say that sticks and stones may break your bones, but words will never hurt you. Yet childhood bullying really can damage your long-term health. Gone are the days when bullying was considered an inevitable and ultimately harmless part of growing up—just last month we learned that childhood bullying can lead to poorer mental health even into middle age. Now William Copeland at Duke University in Durham, North Carolina, and his colleagues have shown that it can have lingering physiological effects too. They tracked 1420 9-year-olds right through their teens. Each child was seen up to nine times during the study and quizzed about bullying. The team then measured levels of C-reactive protein in their blood. CRP is a marker of inflammation (炎症) linked to higher risk of cardiovascular disease (心血管疾病) and problems like diabetes. 'Because we were collecting biological samples throughout, we were able to look at CRP levels in subjects prior to their bullying involvement,' says Copeland. 'This really gives us an idea of the changes bullying brings about.' Although CRP levels naturally rise in everyone during adolescence, levels were highest in children who reported being tormented by bullies. Even at the ages of 19 and 21, children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither perpetrators nor victims. In a cruel twist, the bullies had the lowest levels of all, suggesting they didn't suffer the same health risks. They may even see a benefit from their behavior, though Copeland stresses it doesn't vindicate (辩护) their actions. 'The goal would instead be to find other ways to produce this protective effect without it being at someone else's expense,' he says. Andrea Danese at King's College London has previously shown that maltreatment during childhood can lead to high levels of inflammation in adult life. 'This new study is a helpful addition in showing that these effects extend to another important childhood stressor,' he says. He suggests that care workers could monitor levels of CRP in children having psychotherapy to see if it is helping to soothe the stress of being bullied.

单选题 When families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma's generation. Their tables will be set with the good dishes and silver, and the dress code will be Sunday best. But in many other homes, this china-and-silver elegance has given way to a stoneware (粗陶) and stainless informality, with dresses assuming an equally casual-Friday look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it spells economic hard times. Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is eliminating 1,000 jobs—one-fifth of its total workforce. That brings to more than 4,000 the number of positions lost in 18 months in the pottery (陶瓷) region. Wedgwood and other pottery factories made cuts earlier. Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts. A spokesman for Royal Doulton admitted that the company 'has been somewhat slow in catching up with the trend' toward casual dining. Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television. Even dinner parties, if they happen at all, have gone casual. In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it's better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a 'real' dinner party. Too often, the perfect moment never comes. Iron a fine-patterned tablecloth? Forget it. Polish the silver? Who has time? Yet the loss of formality has its down side. The fine points of etiquette (礼节) that children might once have learned at the table by observation or instruction from parents and grandparents ('Chew with your mouth closed.' 'Keep your elbows off the table.') must be picked up elsewhere. Some companies now offer etiquette seminars for employees who may be competent professionally but clueless socially.

单选题 When companies consider their benefits mix, coverage for medical care is often top-of-mind. Yet there may be another, even more powerful concern driving employee coverage preferences: vision care. Roughly 75% of adults in the United States require some type of vision correction, and 84 percent of adults believe that vision benefits are somewhat or very important to them. As a result, vision assistance is moving higher and higher on the list of sought-after employee benefits. What's driving the trend? One factor is the increasing power of eye examinations to detect systemic illness. In addition to identifying nearsightedness, farsightedness and astigmatism, routine eye exams now play a role in diagnosing conditions such as diabetes, brain aneurysms (脑动脉瘤), liver disease and stroke risk. Early identification, in turn, translates into markedly lower expenditures for employers. In 2014, eye problems will cost companies an estimated $8 billion in reduced productivity. Making sure employees get the right eye care helps employers reduce these losses. At the same time, it boosts their ability to retain loyal workers. So what's the best way to get patients into the exam chair? One way is to provide a vision plan that lowers out-of-pocket (自己付费的) expenses. Indeed, research shows that out-of-pocket expense—not premiums—is the number-one factor employees consider when choosing a vision plan. 'And that's just smart,' says independent insurance broker Shannon Enders. 'Premiums make up only about 30 percent of total out-of-pocket expenses. So it pays to look beyond the premium and see the real cost of a plan.' A study conducted by Service Excellence Group Inc., a leading market research company, shows how the right vision insurance plan can result in across-the-board (全面的) savings for employees. The study compared the prices customers with different insurance plans paid for the same popular pair of eyeglasses at independent doctors and retail chains. It found that customers with insurance plans that were most successful at keeping out-of-pocket expenses low saved hundreds of dollars. With eyeglasses becoming as much of a fashion accessory (装饰品) as a vision aid, forward-thinking companies are beginning to take note. Enders says more of his clients are saying yes to vision care plans. 'Employees care about their eyes,' he says. 'And offering benefits packages with the features employees care most about will become an even more important corporate strategy going forward.'

单选题 Most people can remember a phone number for up to thirty seconds. When this short amount of time elapses, however, the numbers are erased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows stimuli that is of immediate interest to pass on to the STM, also known as the working memory. There is much debate about the capacity and duration of the short term memory. The most accepted theory comes from George A. Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or name rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking, or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage. When making a conscious effort to memorize something, such as information for an exam, many people engage in 'rote rehearsal'. By repeating something over and over again, we are able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, you might attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before you get the opportunity to make your phone call, you will forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice 'elaborate rehearsal'. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories. Encoding information semantically also makes it more retrievable. Retrieving information can be done by recognition or recall. Humans can recall memories that are stored in the long term memory and used often. However, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization.
