Finding the Real You

    Psychometric testing—personality testing—has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.

    The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality type which stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.

    Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “People who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprung up. “It's possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”

    So can we change our personality? “Your basic personalities fixed by the time you're 21,”says Gill, “but it can be affected by motivation and intelligence. If you didn't have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it's why we're seeing this trend for downshifting—too many people trying to fit into a type that they aren't really suited for.”

    Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you'll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.

    Three-quarters of the world's coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides (杀虫剂) and chemicals that poison the environment. When forests disappear, migratory (迁徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification.

    Bird Friendly coffees are shade-grown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shade-grown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more complex flavor. Bird Friendly certified coffees grow under bio-diverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet.

    Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional income. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat.

    Buying Bird Friendly supports the Smithsonian Migratory Bird Center's conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.

    A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion (万亿) connections in the brain of a three-year-old child.

    Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern "A-B-B". Another order was mu-ba-ge. This is the pattern "A-B-C". The images showed that the part of the brain responsible for speech was more active during the "A-B-B" pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

    Gervain is excited by these findings because the order of sounds is the building block of words and grammar. "Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference: 'John caught the bear.' is very different from 'The bear caught John.' "

    Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones－no matter how educational－doesn't appear to be enough for children's brain development. They carried out a study of nine-month-old American babies. They expected the first group who'd watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies－regardless of whether they had watched the video or listened to the audio－learned nothing.

    Monthly Talks at London Canal Museum

    Our monthly talks start at 19:30 on the first Thursday of each month except August. Admission is at normal charges and you don't need to book. They end around 21:00.

    November 7th

    The Canal Pioneers, by Chris Lewis. James Brindley is recognized as one of the leading early canal engineers. He was also a major player in training others in the art of canal planning and building. Chris Lewis will explain how Brindley made such a positive contribution to the education of that group of early "civil engineers".

    December 5th

    Ice for the Metropolis, by Malcolm Tucker. Well before the arrival of freezers, there was a demand for ice for food preservation and catering, Malcolm will explain the history of importing natural ice and the technology of building ice wells, and how London's ice trade grew.

    February 6th

    An Update on the Cotsword Canals, by Liz Payne. The Stroudwater Canal is moving towards reopening. The Thames and Severn Canal will take a little longer. We will have a report on the present state of play.

    March 6th

    Eyots and Aits-Thames Islands, by Miranda Vickers. The Thames had many islands. Miranda has undertaken a review of all of them. She will tell us about those of greatest interest.

If you've ever seen elephant seals (象海豹) lying on a beach, you might think that they're always. sleeping. But in fact, they spend about seven months of the year in the ocean. So how do they sleep while they're in the ocean?

Even though elephant seals are large animals, they have to be careful in the ocean. Near the surface, some dangerous animals like sharks might attack(攻击)them. So elephant seals spend most of their time diving (下潜) deep underwater, looking for food.

To find out how they sleep in the deep, a scientist named Jessica Kendall-Bar created a special cap. She and her team put the caps on thirteen female young elephant seals. The caps recorded the elephant seals brain activities. They also collected information on the elephant seals' heart rates (心率), how their bodies were moving, and how deep they were.

The scientists learned that elephant seals sometimes sleep for a short time while they are diving. They only sleep for about 10 minutes at a time. As they begin to sleep, the elephant seals can control their bodies. But when they are deeply asleep, they simply begin to fall, spinning (快速旋转) in a circle "like a falling leaf". The elephant seals wake up in time to go up for more air. In shallower (较浅的) areas, the elephant seals sometimes wake upon the seafloor.

Using the information they collected from the cap-wearing elephant seals, the scientists created a computer program to study older records of elephant seal trips. The scientists found that elephant seals only sleep for about two hours a day when they're in the ocean. That means that the rest on land is very important for them. Back on land, they sleep for about 10. 8 hours a day.

The scientists hope that their work will help to protect the places where elephant seals sleep when. they're on land.
