Watching a 3D movie can more than double the concentration powers and cognitive(认知) processing of children, a new research claims.

    A study made by visual technology firm RealD and led by child psychologist Dr. Richard Woolfson suggests that children aged between 7 and 14 experienced twice the cognitive processing speed and performed better in testing after watching 20 minutes of a 3D film. This is despite suggestions that attention spans(时期) in children have shortened in the last decade due to unlimited to access to entertainment, including on-demand TV, gaming and social media. A 2015 study claimed that watching 3D content had a similar effect to brain-training exercises.

    Consumer psychologist Mr. Fagan said that the increased stimulation(刺激) found in watching something in 3D "exercised" the brain and improved performance in the short term. "3D films can play the role of ‘brain-training' games and help to make children ‘smarter' in the short term," he said. "The shortening of response times after watching 3D was almost three times as big as that gained from watching 2D; in other words, 3D helps children process aspects of their environment more quickly. This is likely to be because 3D is a mentally stimulating experience which ‘gets the brain's juices flowing'."

    The experiment saw children given a range of cognitive tests before watching 20 minutes of a movie in either 2D or 3D and being tested again. The results showed those who saw the 3D content reacted faster and performed bettering the second round of testing. Mental engagement also rose by 13% among 3D watchers. Child psychologist Dr. Woolfson added that “supportive parenting” and regularly listening to classical music can also aid a child's memory.

    When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer the older we get.

For kids, happiness has a magical quality. Their delight at winning a race or getting a new bike is unreserved (毫无掩饰的).

    In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy—love, marriage, birth—also bring responsibility and the risk of loss. For adults, happiness is complicated (复杂的).

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunch-box and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband come home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children, had much of either. She did have a network of close friends and family, and maybe this what satisfied her.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to—it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have , but enjoying what we do possess.

    From the very beginning of school we make books and reading a constant source of possible failure and public humiliation. When children are little we make them read aloud, before the teacher and other children, so that we can be sure they “know” all the words they are reading. This means that when they don't know a word, they are going to make a mistake, right in front of everyone. After having taught fifth-grade classes for four years, I decided to try at all costs to rid them of their fear and dislike of books, and to get them to read oftener and more adventurously.

    One day soon after school had started, I said to them, “Now I'm going to say something about reading that you have probably never heard a teacher say before. I would like you to read a lot of  books this year, but I want you to read them only for pleasure. I am not going to ask you questions to find out whether you understand the books or not. If you understand enough of a book to enjoy it and want to go on reading it, that's enough for me. Also I'm not going to ask you what words mean. “

    The children sat stunned and silent. Was this a teacher talking? One girl, who had just come to us from a school where she had had a very hard time, looked at me steadily for a long time after I had finished. Then, still looking at me, she said slowly and seriously, Mr Holt, do you really mean that?” I said just as seriously, “I mean every word of it.

    During the spring she really astonished me. One day, she was reading at her desk, From a glimpse of the illustrations I thought I knew what the book was. I said to myself, “It can't be,” and went to take a closer look. Sure enough, she was reading Moby Dick , in edition with woodcuts. I said, “Don't you find parts of it rather heavy going?” She answered, Oh, sure, but I just skip over those parts and go on to the next good part. “

    This is exactly what reading should be and in school so seldom is, an exciting, joyous adventure. Find something, dive into it, take the good parts, skip the bad parts, get what you can out of it, go on to something else. How different is our mean-spirited, picky insistence that every child get every last little scrap of “understanding” that can be dug out of a book.

    Emma and Ryan, a married couple, were driving to a friend's house when Emma turned to Ryan and asked, “Would you like to stop for lunch?”

    Ryan replied. “No, I'm not hungry yet,” and continued driving. Meanwhile, Emma sat quietly fuming (十分恼火)in the passenger seat. Ryan could not understand why Emma was unhappy. He had thought she was asking if he was hungry, but in reality, Emma was telling him that she was hungry and wanted to stop for lunch.

    Misunderstandings like this often occur between men and women, even among people from the same culture. Deborah Tannen, professor of linguistics at Georgetown University in the United States, has studied conversational rules.

    In Emma and Ryan's situation, Emma was making a request in the form of a question. Her style of talking is common for women. She needed Ryan to agree they were both hungry. So, Emma asked Ryan what he wanted. She was really telling Ryan what she wanted; however, Ryan did not understand this. If he had been hungry, he would have said something more direct, such as, “I'm hungry. Let's have lunch.”

    Tannen believes that most women grow up in a world where talk is used to express feelings. However, most men are raised differently and they tend to keep their feelings to themselves.

    Tannen says, for men, talk is often used as a situation used outside the home to gain respect, to entertain and get attention , or to exchange information. This is why men communicate by making each other laugh, or talking about sport and work. These men do not always feel it is necessary to talk to feel close or to express their feelings. Women, on the other hand, are encouraged to speak about their feelings since this is a way to build relationships.

    People who play computer games to train their brains might as well be playing Super Mario, new research suggests.

    In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.

    More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills, for at least 10 minutes a day, three times a week.

    They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet. All participants were given an "IQ test" before and after the experiment.

    Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet.

    "If you're(playing these games) because they're fun, that's absolutely fine," said Adrian Owen, assistant director at Britain's Medical Research Council. "But if you're expecting these games to improve your IQ, our data suggests this isn't the case."

    Computer games that are supposed to improve memory, reasoning and other cognitive skills are played by millions of people worldwide, though few studies have examined if the games work.

    "There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, a professor of psychology at the University of Illinois, US.

    Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can help produce new brain cells.

    Other experts said brain games might be useful, but only if they weren't fun.

    "If you set the level for these games to a very high level where you don't get the answers very often and it really annoys you, then it may be useful," said Philip Adey, a professor of psychology at King's College in London.

    If people are enjoying the brain games, Adey said they probably aren't being challenged and might as well be playing a regular video game.

    He said people should consider learning a new language or sport if they really want to improve their brain power. "To stimulate(激发) the intellect, you need a real challenge," Adey said, "Getting smart is hard work."

    One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.

    A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only one-twelfth of a tea spoon of me.

    The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.

    Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return.
