Multitasking
People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”

Speakers of different languages not only describe the world differently but think about it differently too, according to a new study.
Researchers used a cartoon cat Sylvester to study how language was reflected (反映) in the gestures people made. Dr. Sotaro Kita of the University of Bristol’s Department of Experimental Psychology (心理学), showed the cartoon to a group of native English, Japanese and Turkish speakers and then watched their gestures as they described the actions they had seen. He found speakers of the three different languages used different gestures to describe the same event, which appeared to reflect the way the structure of their languages expressed that event. For example, when describing a scene where the cat swings on a rope, the English speakers used gestures showing an arc trajectory (弧形轨迹) and the Japanese and Turkish speakers tended to use straight gestures showing the motion but not the arc.
Dr. Kita suggests this is because Japanese and Turkish have no proper verb to express the English meaning “to swing”. While English speakers use the arc gesture as their language can readily express the change of location and the arc-shaped trajectory, Japanese and Turkish speakers cannot as easily express the idea of movement with an arc trajectory so they use the straight gesture.
Dr. Kita said, “My research suggests that speakers of different languages cause different spatial (空间的) images of the same event in a way that matches the expressive possibilities of their own languages. In other words, language influences (影响) spatial thinking at the moment of speaking.”

Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.
This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.
Researchers studied groups of people from the University of Wisconsin－Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.
The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.
“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing，” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitve and Brain Science.
When our minds run out of working memory, these off－topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.
“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read，” study researcher Daniel Levinson, said in a statement.
People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.
The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.

| B．On the working memory test, people with wandering minds will get high score. |
| C．Absorbed in the mind wandering, your attention left no space for your goal. |
| D．Dealing with some easy jobs, people with higher working memory will daydream. |

| B．Daydreaming is good for the mind. |
| C．Creative moments come with working memory. |
| D．The more daydreaming, the more effectively one works. |
“Old wives’ tales” are beliefs passed from one generation to another. For example, most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.
Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic(蒜) is good for you, too. It can kill the type of virus that causes colds.
Unfortunately, not all of Mom’s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.
Even though science can tell us that some of our traditional beliefs don’t hold water, there is still a lot of truth in the old wives’ tales. After all, much of this knowledge has been accumulated(积累) from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.
【小题1】The author develops the third paragraph mainly .
| A．by cause and effect | B．by order in space |
| C．by examples | D．by order in time |
| A．Eating garlic is good for our eyes. |
| B．Carrots prevent people from catching colds. |
| C．Swimming after a meal is dangerous. |
| D．Sticky sweets are damaging to our teeth. |
| A．Objective. | B．Subjective. | C．Dissatisfied. | D．Curious. |
| A．to be valuable | B．to be believable |
| C．to be admirable | D．to be suitable |
What exactly is a lie ?Is it anything we say which we know is untrue ?Or is it something more than that ?For example, suppose a friend wants to borrow some money from you. You say “I wish I could help you, but I am short of money myself.” In fact , you are not short of money but your friend is in the habit of not paying his debts and you don’t want to hurt his feelings by reminding him of this. Is this really a lie ?
Professor Jerald Jellison of the University of southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a “white lie”, such as when a woman at a party tells another woman that she likes her dress when she really thinks it’s terrible. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise that they have no intention of carrying out. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at :the lie from which the liar hopes to profit or gain in some way.
Research has been done into the way people’s behavior changes in a number of small, unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now”. They also tend to touch certain parts of the face, particularly the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose is very sensitive to changes and the increased pressure makes it itch.
Another gesture that gives liars away is what the writer Decmond Morris in his book Man Watching calls the “mouth cover”. He says that there are several typical forms of this ,such as covering part of the mouth with the fingers, touching the upper lip or putting a finger of the hand at one side off the mouth. Such a gesture can be understood as an unconscious(未察觉的) attempt on the part of the liar to stop himself from lying.
Of course, such gestures as rubbing the nose or covering the mouth , moving about in a chair can not be taken as proof that the speaker is lying. They simply tend to happen more often in this situation. It is one gesture alone that gives the liar away but a whole number of things , and in particular the context(上下文) which the lie is told.
