Most damagingly, anger weakens a person's ability to think clearly and keep control over his behaviour. The angry person loses objectivity in evaluating the emotional significance of the person or situation that arouses his anger.

    Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels (决斗) as an appropriate expression of anger resulting from one person's awareness of insulting behaviour on the part of another.

    Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG (脑电图) measures of electrical activity show balanced activity between the right and left prefrontal (额叶前部) areas. Behaviourally this corresponds to the general even-handed disposition (意向) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren't balanced and, as a result of this, we're likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative.

    Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as of ensive anger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approach-and-confront behaviour is accompanied by a leftward prefrontal asymmetry (不对称) of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy (同感) towards the individual who is bringing forth the angry response. In defensive anger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger-inspiring situation.

    The word advertising refers to any kind of public announcement that brings products and services to the attention of people. Throughout history, advertising has been an effective way to promote(促进)the trading and selling of goods. In the Middle Ages, merchants employed "town criers" to read public messages aloud to promote their goods. When printing was invented in the fifteenth century, pages of advertisements(ads)could be printed easily and were either hung in public places or put in books.

    By the end of the seventeenth century, when newspapers were beginning to be read by more people, printed materials became an important way to promote products and services. The London Gazette was the first newspaper to set aside a place just for advertising. This was so successful that by the end of the century several companies started businesses for the purpose of making newspaper ads for merchants.

    Advertising spread quickly throughout the eighteenth century. Ad writers were starting to pay more attention to the design of the ad text. Everything, from clothes to drinks, was promoted with clever methods such as repetition of the firm's name or product, words organized in eyecatching patterns, the use of pretty pictures and expressions easy to remember.

    Near the end of the nineteenth century, companies that were devoted to the production of ads came to be known as "advertising agencies(广告商)．"The agencies developed new ways to get people to think of themselves as members of a group. Throughout the twentieth century, advertising agencies promoted consumerism(消费主义)as a way of life, spreading the belief that people could be happy only if they bought the "right" products.

    Watson entered Mr. Smith's office. The boss was a hard man. He fired people who didn't do well without giving them a second chance.

    “Watson,” said Mr. Smith, “this past year your department hasn't earned money. We're going to drop that department. It's finished. I'm sorry, —but you'll have to go.” “But, sir — if I just had a little more time. For the moment I need the job to keep my son at Riverside School.”

    “What's that!” said the boss. “Riverside! I didn't know you had a boy there. That's an expensive school for a man with your salary.”

    “I know, sir. But he likes it there so much! He's a star athlete and the best boxer in the school. The boys call him Champ there.”

    The boss sat perfectly still for a long time — a faraway (恍惚的) look in his eyes. Then, suddenly, he said, “We've got to close your department, Watson. But you'll take over a new job in another department. It means longer hours—maybe more pay. Now get out. You're here for life.”

    Watson got out, with surprise on his face. Then the boss took a letter from the top drawer of his desk. It was Herbie's last letter from Riverside School —written a few days before he died. He had read it over and over again with sick pain. The letter read:

    I can't say the boys here are any nicer to me than the others were. I guess it's the same everywhere when you're a cripple (跛脚的人). But don't worry about me, Dad, They've got a good chemistry department here. And there's one boy here who is really great. He's a track star and boxing champ (冠军) and just tops in chemistry.

    The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big — that he won't even know about.

Your son,

Herbie

    One day, I was in class, feeling fine, when all of a sudden my heart started racing. I broke out in a sweat, feeling hot and cold all over. My chest hurt, I was dizzy, and I felt like I couldn't breathe. Everything went blurry around the edges. Sure I was about to faint, I jerked up from my desk and ran from the room, terrified. I didn't care what the teacher thought, or that the eyes of the entire class were on me. I just had to get out of there.

    I ran to the nearest water fountain and drank some water. For several minutes, I just stood there holding on to the fountain. What was happening? Was I having a heart attack? Slowly, the lightheadedness went away. My heart stopped racing, and every other symptom faded too. I still had no idea what had happened but I was so glad it was over.

    Still I was really worried. I'd never felt that bad in my life. What was wrong with me? What if it came back?

    And then, an hour later, it did the pounding heart, the dizziness, the feeling that I was dying. Once again, I couldn't breathe. And this time, there was also pain throughout my entire upper body. I burst into tears and ran for the hallway again, actually afraid for my life. My teacher ran after me asking what was wrong. Panicking, I managed to choke out, "I need an ambulance: Please." I was sure I was dying.

    To my surprise, though, my teacher didn't grab her phone for help. Instead, she put her hand on my arm and told me to slow down. "Breathe, "she said." you're going to be okay. You just need to calm down. "

    I felt like I was going crazy. Here I was totally losing it, and she was acting like nothing was wrong! She kept on trying to calm me down, but I wasn't ready to listen. I was sure she didn't understand how I felt. How could she? How could anyone? Finally, my teacher explained that she was pretty sure I was having a panic attack. (They are also called anxiety attacks.) She knew, she said, because the same thing had happened to her when she was my age. She told me how she'd felt, and it was almost exactly how I was feeling now. She also explained that panic attacks are caused by anxiety (basically, excessive worry and fear that is part of your everyday life).

    I was shocked. I had no idea that there was even a name for what I was feeling let alone that it happened to other people, too! When I realized that she really did understand, I felt so relieved.

    My teacher talked to my parents, and they found me a counselor to help me deal with my anxiety. I'd been going through a tough time that year. My best friend had moved to a new school, and I wasn't sure how to fit in with the girls in my class. I'd never told anyone, though--I just kept it to myself. My counselor helped me understand that not dealing with my feelings can lead to panic attacks, and that I need to talk to someone when my life is stressful.

    Now when I start feeling overwhelmed or sad, I talk to my parents or friends and my counselor about whatever is bothering me, and they all help me sort things out. This way, I' m dealing with my anxiety and stress before it gets out of control.

    My counselor has also taught me some relaxation techniques and strategies that help me calm my body down at the first sign of a panic attack. I've learned to take deep breaths and relax my muscles. Or I'll focus on something else, or just tell myself I'm going to be okay. If one thing doesn't work, I'll try another one.

    It turns out that about one in every ten people has some kind of an anxiety disorder! Knowing that it's common and that life is stressful for a lot of girls of my age has helped me realize that I don't have to be ashamed or embarrassed about it.

    By sharing my story, I want other girls of my age to know that you're not as alone as you feel, and that talking about it really does help.

Learning New Vocabulary during Deep Sleep

    Sleeping time is sometimes considered unproductive time. This raises the question whether the time spent asleep could be used more productively, e.g. for learning a new language? Up-to-now sleep research focused on the stabilization and strengthening of memories that had been formed during wakefulness. However, learning during sleep has rarely been examined. There is enough evidence for wake-learned information undergoing a revision by replay in the sleeping brain. The replay during sleep strengthens the still weak memory and leaves the newly acquired information in the pre-existing store of knowledge.

    If re-play during sleep improves the storage of wake-learned information, then first-play, i.e. the initial processing of new information, should also be possible during sleep.

    The research group of Katharina Henke examined whether a sleeping person is able to form new semantic（语义的）associations between played foreign words and translation words during the brain cells' active states, the so-called "Up-states." It turned out to be that what they thought was reasonable. When we reach deep sleep stages, our brain cells progressively coordinate their activity. During deep sleep, the brain cells are commonly active for a brief period of time before they jointly enter into a state of brief inactivity. The active state is called "Up-state" and the inactive state "Down-state". The two states alternate（交替）about every half-second.

    New evidence for sleep-learning challenges current theories of sleep and theories of memory. The concept of sleep that we are separated from the physical environment is no longer reasonable. "It's false that complex learning be impossible during deep sleep," says Simon Ruch, co-first-author. "In how far and with what consequences deep sleep can be applied for the acquisition of new information will be a topic of research in upcoming years," says Katharina Henke.

    The research group of Katharina Henke is part of the Interfaculty Research Cooperation (IRC). Thirteen research groups in medicine, biology and psychology are part of the IRC. The aim of these research groups is to gain a better understanding of the mechanisms（原理）involved in sleep and consciousness.

    Eating out is such a pleasure ― the food, the wine, the joy of having it all brought to you by someone else—that it's a pity to ruin the experience by sharing it with other people.

    Well, I do like visiting restaurants with friends. But dining out alone has its own very special attractions. For a start you can give all your attention to the food. There's nothing worse than having to invent and deliver an opinion on school league tables or Sanchez's move to Manchester United, plus listen to everyone else's opinions, when all you really want to do is enjoy each mouthful along the way.

    A second great thing about eating out alone is the chance to combine food with one of life's other true pleasures: reading. You have to plan this carefully: Indian or Chinese restaurants are best ― you need food you can eat with just one hand, leaving the other free to hold your reading material.

    But perhaps the biggest attraction of a table for one is the chance it gives to people-watching. Restaurants and the different reasons for visiting them ― first date, business meeting, night out with friends ― produce human behaviour of surprising richness and variety. Will the man selling his business idea get any joy out of his possible investor (投资者)? Will the married couple think of anything to say to each other before their main courses arrive?

    This "human zoo" part of eating out alone is one of the reasons I'd hate to be famous: everyone would be watching you, so you wouldn't be able to watch them. The snooker player Steve Davis says this was one of the strangest consequences (后果) of becoming well-known: he got very worried about his eating in public, almost to the level of doubting whether he was "doing it right."

    So next time you're considering your eating out choices, remember the advice of the businessman Nubar Gulbenkian: "The best number for a dinner party is two ― myself and a super head waiter."
