Working with a group of baboons (狒狒）in the Namibian desert, Dr. Alecia Carter of the Department of Zoology，Cambridge University set baboons learning tasks involving a novel food and a familiar food hidden in a box. Some baboons were given the chance to watch another baboon who already knew how to solve the task, while others had to learn for themselves. To work out how brave or anxious the baboons were, Dr. Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake.

    She found that personality had a major impact on learning. The braver baboons learnt, but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did. In effect, despite being made aware of what to do, they were still too shy to do what the experienced baboon did.

    The same held true for anxious baboons compared with calm ones. The anxious individuals learnt the task by observing others while those who were relaxed did not, even though they spent more time watching.

    This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals, something that has previously been ignored in studies on how animals learn to do things. The findings are significant because they suggest that animals may perform poorly in cognitive (认 知的）tasks not because they aren't clever enough to solve them，but because they are too shy or nervous to use the social information.

The findings may impact how we understand the formation of culture in societies through social learning. If some individuals are unable to get information from others because they don't associate with the knowledgeable individuals，or they are too shy to use the information once they have it，information may not travel between all group members, preventing the formation of a culture based on social learning.

    The new study shows that we spend more time using the mobile Internet reading newspapers or magazines or doing some other things. According to the European Interactive Advertising Association(EIAA), the average European spends 4.8 hours reading newspapers and magazines but 1.6 hours more using the mobile Internet a week.

    The EIAA questioned 15,000 people in 15 European countries, looking at how people are using the Internet and its influence on their everyday lives. It found that the mobile Internet is increasingly finding its way into the public awareness. Over 71 million Europeans now have Internet access on their mobile phones. In the UK, 10 million people now access the Internet through their mobile phones and spend 6.3 hours doing so in a week.

    Unsurprisingly, younger generations in the UK are leading the way, with nearly half of the country's 16-to 24-year-olds and a quarter of 25- to 34-year-olds using the Internet, spending 6.5 and 6.2 hours online each week.

     Entertainment plays a main role in our mobile Internet lives, with one in five British people using their phones for online games, a third listening to the online radio and 39 percent watching films, TV or other videos at least once a week. One third of those using an Internet phone said they received videos, images or other multimedia on their mobile, and 61 percent said they passed on contents they received.

    From a communication point of view, 80 percent of those questioned agreed that the Internet had made it easier for them to stay in touch with friends and family.

    Alison Fennah, director of the EIAA, said the mobile Internet use had come to the point that marketers should be looking to develop strategies (策略) that connect with consumers more effectively. “Better devices as well as improved consumer motivation that start coming together in 2011 can make a great difference to extending the online experience.” Fennah said.

    What do you think of cats? Some people think very lovely. But not all people love cats. Compared with dogs, cats seem to be very lazy and unfriendly. Besides, cats are not known for acts of selflessness (无私). But maybe we're wrong about them. Don't believe it? Then meet Pippa, a very unusual cat.

    The black-and-white cat was left in a box outside a shop and taken by the British RSPCA to the Jansa family in Whitstable, Kent. They really loved her character (性格) and decided to adopt (收养) it，but they never guessed she'd become a lifesaver.

    Eight-year-old Mia Jansa had diabetes and had become good at testing her blood during the day, as well as having something to eat or drink to bring her blood sugar levels back. But the danger was at night. Mia could easily experience hypoglycemic (低血糖症的) situations when she was asleep, which could cause even death.

    Soon after she was adopted, Pippa went into Mia's bedroom in the middle of the night and woke her up. When the child tested her blood sugar levels, she found they were dangerously low. Ever since, Pippa always visits Mia at night. If she can't get her to wake up, she raises the alarm.

    “Pippa does this of her own accord,” says Mia's mother Laura. “We don't make a request for caring because we don't want to encourage wrong alarms. She gets plenty of hugs. It gives me peace of mind and I know someone else is keeping an eye on Mia.”

    Now the family is so happy that they've chosen to adopt it in the first place.

    The following children's books are our top picks to read together every year on Christmas Eve.

    Snowden written by Nancy Carlson

    This book is aimed at pre-school to the third-grade children, but can be enjoyed by many older children as well. Snowden is the story of a little girl and the snowman she makes that magically comes to life. Together, the two learn to ice-skate and discover that “a little magic and a lot of practice” can make all the difference in the world. The story is heart-touching and sweet.

    The Polar Express written by Chris Van Allsburg

    A young boy cannot sleep on Christmas Eve and is swept away by a steam engine on a trip to the North Pole. During the adventure, the message is that believing will keep you young at heart. The bell that the boy receives and his belief are both touching. The illustrations leave enough to the imagination to make it easy to fall into the story yourself.

    A Snowman Named Just Bob Written by Mark Kimball Moulton

    This book shares a tale of lasting friendship and teaches the lesson that friendship is always in your heart. The illustrations are beautiful and the text is eye-catching. The lessons are taught in such a way that they do not overshadow (使失色) the actual story. I tear up every time I read this book to my children.

    At times my mom has been uncomfortable seeing some quality in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

    But despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn, even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away, she was supportive and excited for me.

    One big thing I realized during my senior year, as my mom granted me more freedom, was that she actually believes in me and trusts me. That means a lot. Most of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards: getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's.

    I know that her high standards have helped me stay focused on what's important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

Being a good parent requires providing a child with the gifts of love, attention, energy, and resources unstintingly over a long period of time. It involves developing a small body, but it also involves growing a child's soul.

Parents are an enormously powerful force in the lives of children. Whether Johnny can read, whether Johnny knows right from wrong, whether Johnny is a happy, well-adjusted kid, or sad and self-destructive, has a whole lot to do with the kind of parenting Johnny has received. If Johnny's mom and dad have been able to come through with lasting, loving attention, the chances are that Johnny is on track to become a productive, compassionate (富有同情心的) person. If they have not, Johnny is in trouble.

Thirty years ago Chicago professor James S. Coleman showed that parental involvement mattered far more in determining school success than any quality of the formal education system. Across a wide range of subject areas, in literature, science and reading, Coleman estimated that the parent was twice as powerful as the school in determining achievement at age fourteen. Psychologist Lawrence Steinberg, who recently completed a six-year study of 20,000 teenagers in nine different communities, confirms the importance of parents. Steinberg shows that one out of three parents is "seriously disengaged" from his or her adolescent's education, and this is the primary reason why so many American students perform below their potential and below students in other rich countries.

A weight of evidence now demonstrates obvious links between absentee parents and a wide range of behavioral and emotional problems in children. A 1997 study of 90,000 teenagers — the Add Health Project undertaken (承担) by the Carolina Population Center and the Teenage Health Program at the University of Minnesota found that youngsters are less likely to get depressed, use drugs or become involved in crime when they spent significant time with their parents. This study found that the mere physical presence of a parent in the home after school, at dinner and at bedtime significantly reduces the incidence of risky behavior among teenagers.
