昆明市西山区脸部去痣价格昆明省妇保医院整形科As I write this I’m ending a frantic week trying to get everything together before we go on holiday (vacation) to Gozo. As you this (if its around 27th July) I should be totally chilled (but also very hot!) as I relax on holiday. So with that in mind I thought I’d write a quick checklist of things you can do if to keep stress at bay and feel more relaxed.Stress is a bit of a fashionable buzz word. There are similarities and links between stress and anxiety - both can lead to unpleasant, disabling symptoms. When we feel stressed we often feel out of control of the situation - which undermines our self confidence.So try these ten easy relaxation tips to feel more relaxed and in control.1. Take a short break and leave a stressful situation. If you are at work, offer to run an errand or go for a short walk. A few minutes away can help you think clearly and the walk will get rid of some of the tension in your body.2. Take a break from the activity you are working on and do something different. Sometimes it helps to come back to a stressful task later when you feel more relaxed instead of persevering. If you are at home with small children it is often better to stop when they, and you, become frustrated and take some time out to do something else so everyone can calm down.3. Listen to relaxing music while you work. Listening to classical or nature music has been shown to lower heart rate and slow breathing. People often report feeling calmer after listening to calming music. Develop the habit of playing music in the background while you work for easy relaxation.4. Take regular breaks during the day. Spend 5-10 minutes to something uplifting or humorous, or chat with a friend. Small breaks help to prevent your mind and body from becoming fatigued, a major source of stress.5. Practice mindfulness. Mindfulness is the ability to be fully aware of the present moment. It is a skill that helps to reduce stress and depression. Learning relaxation techniques is a good way to start learning mindfulness. As you gradually become more aware of your body and subtle changes that occur with relaxation your ability to notice small changes will improve. Start by spending 5 minutes a day just sitting in the quite noticing the sights, sounds and bodily sensations you are having. You can also learn mindfulness through meditation techniques.6. Change your focus. As people feel more stressed their attention becomes focused on what they believe to be the cause of their stress and they ignore other information. Write down the things that were good about the day. Keep a gratitude journal.7. Have a hot bath or shower. This will help to get rid of the tension in your muscles which is a normal result of stress.8. Write down the things that are worrying you. If you are worried it is very difficult to relax easily. Once you have written them down then see how much control you have over them. Can you take any action to solve the problem or are you worrying about things that are out of your control. Worry is a habit that can be helped by learning effective relaxation techniques.9. Keep things in perspective. Ask yourself ‘how important is it?’ ‘How important will it be in a year’s time?’ Many of the things that cause stress are not important when we look at the big picture.10. Slow your breathing and purposefully relax your body for quick results. This will be easier if you have learned easy relaxation methods that you can use when you need them. I’ll add more relaxation techniques in a future post. 我写这篇文章,以此在去Gozo度假之际,结束之前试图收拾好一切的疯狂一周。读这篇文章时(如果时间是在7月27日左右),我应该完全处于休假地的寒冻之中(但其实也很热)。所以想来想去我觉得该写一个快速一览表,教你如何远离压力,体验轻松。压力是个挺流行的术语。它和焦虑既有相同点又有某些联系--它们都会导致令人不快的能力丧失综合症。当我们倍感压力时通常也会感到自己对场面失去了控制--这会打击我们的自信心。所以试试以下十条简单的放松小贴士吧,放松一下自己,控制好自己的情绪。1. 休息一会儿放松下紧张的神经。倘若你正在工作,让自己也当回跑腿,或者去散会儿步吧。只要离开几分钟就能促使你思维清晰,而散步还能让你摆脱身体的疲劳。2. 放下你手头的工作去做些别的。有时松弛的状态比起死命的蛮干更有助于你稍后再回到紧张的工作中。倘若你正和孩子们呆在家里,最好在你们都感到情绪低落时,出去做些其他的,让每个人都平静下来。3 .工作时听听轻音乐。听古典乐或自然音乐已被实能够降低心率和减缓呼吸频率。人们总是觉得在听过舒缓的音乐后感到自己心平气和。记得在你工作时听听音乐以获得放松,把它培养成习惯吧。4. 白天工作时进行有规律的休息。花5到10分钟时间读些振作精神的或幽默搞笑的东西,抑或和朋友聊聊天。短时间的休息能防止你身心俱疲,这也是压力的重要来源。5. 要多关注身边的一切。关注你周围是一种认清现状的能力,是一种有益于减轻压力和抑郁的技能。学习放松技巧是开始学习关注的好方法。随着你越来越注意自己的身体以及自己放松时的细微变化时,你观察细小变化的能力也增强了。开始时每天花5分钟仅仅静坐着注意自己的视觉、听觉和身体的感觉,你也可以通过一些冥想的技巧来学习关注。6. 转移注意力。人们愈加感到压力巨大,却把注意力集中在他们所认为的压力根源上,而忽视了其他信息。写下一天中感到还不错的事,拥有自己的感谢杂志吧。7. 洗个热水澡吧。它会帮你摆脱通常由于压力而造成的肌肉痉挛。8. 写下你认为正在困扰你的事。如果你真的很担忧,想要立刻放松下来就很难了。一旦写下后看看自己对它们有多少控制力。你能够采取一些措施来解决问题 呢还是担心事态的发展会超出你的控制范围呢。担忧是一种习惯,通过学习有效的放松技巧对其有一定的帮助。9. 以正确的眼光看待事物。问问你自己‘它到底有多重要?’‘一年后它又有多重要?’从大局来看许多导致我们压力的事并不很重要。10. 调整你的呼吸,有意放松身体以获得速效。如果你学习了简单的可以随需随用的放松小方法,这就会简单很多。在以后的信件中我会提供更多的放松技巧。 /200810/53818云南吸脂哪家好 Love your work so it can be fun, interesting, and challenging. Here is how to do it.爱你的工作吧,这样它就会变得可爱,有趣而且富有挑战。下面就谈一下怎么个爱法。Start with a positive attitude. Developing the right attitude towards work makes it much easier to accept and do it. It minimizes fatigue because your mind and your heart is set into it. Convince yourself, nothing good will come out if you fret and do nothing about it.首先得有个积极的态度。培养一种正确的工作态度能让人更容易接受工作并做好它。由于你的整个身心都投入到工作中,因而不容易感到疲乏。说你自己,如果你偷懒或无所事事就不会有任何好结果。Put interest into it. Once you have the enthusiasm, it becomes easy to start things. Then everything will follow smoothly. Remember, interest can always be cultivated. Start thinking that it is something worth doing. Think that you can do it and learn from it.注入自己的兴趣。一旦你有了热情,那么干任何事就变得很容易了。记住,兴趣总是可以培养出来的。开始设想这件事值得去做,然后想你能做而且能从中受益。Create the right ambiance when you do the work. Perhaps you can do it in a place where you are most comfortable, in a clean and refreshing surrounding. Or you can have a friend or family member to help you. This keeps you from being bored. It can also be fun. Or you can have music to inspire you as you work.工作时创造良好的氛围。你可以在一个自己感到非常舒的,干净整洁的环境里做事。或者你可以找一个朋友或亲戚帮你做事。这能让你摆脱枯燥,而且也很有意思。或者你可以在工作时听听音乐来调节气氛。Be creative. You can think of work as play. Plan on how it can be in the form of play that is not fun be a challenge as well.富有创造性。你可以把工作当成玩乐。想一下怎么把工作像玩乐一样完成,这不仅有趣而且也很有挑战性。Always think that at the end of the work, there is something that you have accomplished. This makes you feel proud that you are worth not only as a person but a responsible member of your family.工作结束后始终想着你已经取得了些成果。这样可以让你觉得很自豪,因为你不仅是个有价值的人,而且是个有责任心的家庭中的一员。 /200908/82212读懂美国人的幽默(二) 美国人的笑话有很多都是关于嘲笑不同种族的。美国人怎么开犹太人的玩笑? 问: Why do Jews have such big noses? (为什么犹太人都有大鼻子?)答: Because air is free. (因为空气是免费的)你得知道两个文化点才能明白这个笑话:1. 美国人眼中的犹太人都有个大大的鹰钩鼻。2. 犹太人又精明、又小气。我们很多中国人都有这样一个概念:犹太人是绝顶聪明的。事实上呢?我不知道是不是全部如此,但是我在美国的犹太人的朋友们都是非常聪明的,而且特别有生意头脑。从达芬奇《最后的晚餐》中塑造的犹太人形象开始,犹太人就给人西方人留下了这样的印象:长着一个大大的鹰钩鼻。莎士比亚的《商人》又强化了人们对犹太人“精明、算计、贪婪”的印象。所以在这个笑话里,“空气是免费的”的背后文化含义就是犹太人的精明和小气。 记得有一次一个朋友带我去酒吧喝酒。他告诉我说那里的酒是免费的,于是我高兴得都要跳起来了。他于是对我说:“Are you Jewish or something? (你是犹太人还是怎么着?)”。大家不要轻易开关于别的种族的玩笑,在美国,一般,只有自己开自己种族的玩笑才是安全的,无害的。那你问,那你那个朋友怎么可以开关于犹太人的玩笑。是,我的那个朋友就是个犹太人。^_^好了,考你一个笑话,看你看懂没有: 问: What's "Jewish dilemma?" (什么能够让犹太人进退两难?)答: Free Pork. (免费的猪肉)文化点:1. 犹太人小气 2. 犹太人因为宗教愿意是不应该吃猪肉的。 Get it? 再给大家来一则关于犹太人的笑话:问: What's the difference between Jews and canoes? (犹太人和独木舟的区别在哪里?)答: Canoes tip. (独木舟能倾倒而犹太人不会倾倒) 你一头雾水吧!什么乱七八糟的?在英语里的很多笑话,都用了双关语 (pun). 在英文里,tip不仅表示“倾斜、倾倒”,还表示“给小费”的意思。所以这则笑话又是在指桑骂槐说犹太人小气,不给消费。说到这,给来美国旅游的国人提个醒。在美国餐馆用餐是要给小费的。消费的数量是在用餐结帐数字的 15% 到 20%。大家别忘了。 好了,下面这个笑话是关于犹太妈妈 (Jewish mother) 的。你说,啊?关于犹太人的妈妈还有说法,对! 没错!Q: What did the waiter ask a group of Jewish mothers? (侍应生问了一帮犹太妈妈一个什么问题?)A: "Is anything all right?" (有没有任何事情令您满意的?) 在这个笑话里展示出来的犹太妈妈的形象是斤斤计较,非常不通情理,很难伺候。因为在英文里,侍应生在餐馆招待顾客的时候,问的问题往往是:“Is everything alright?” 一切都还好吧!一般也就是那么一问,不会指望你来真的挑错。但是在这个笑话里,把“everything”变成了“anything”,表示有没有一样事情是你不会挑出错来的?关于 Jewish mother, 还有另外一些说法: 犹太妈妈有点像咱们的中国家长,从儿女出生来到儿女成年、结婚、生子都要亲历亲为,参政议政感极强。她们对儿女婚事的过问、参与程度绝对不会亚于我们的中国家长。这也是美国人对犹太妈妈的一些看法。关于美国黑人的文化背景 在美国,对黑人政治上正确的的说法(politically correct)是African American。(非洲裔美国人)。这么来形容黑人,的确是尊敬他们了,但是少了些亲切感。所以我平常听到的形容黑人的说法是这样的。“That cute black guy, that hot black girl (那个帅气的黑人男孩,那个性感的黑人女孩。)。瞧,在black前面加上“cute” 和“hot”这个两个词,一下子,black就不是什么问题了。但你说,如果我想形容的人既不帅,也不性感怎么办?在中国我们现在不是流行无论管睡都叫靓女吗?美国也可以这么干。好听话不会有人介意的。关于美国人有种族歧视的观念我在这里不想提,以免将错越描越黑。在美国人眼里,黑人通常是擅长各式运动的,尤其是篮球。这和黑人在篮球以及田径上的霸主地位十分不开的。此外对黑人的stereotype还包括黑人,尤其是女孩子很会跳舞。此外,有一个观点是怎么中国人也有的,那就是黑人女孩子的屁股特别的漂亮,又挺又翘又结实。这也是黑人女孩子们自己引以为自豪的。这里我想提几个国人不知道的,但是,我再次重申,不要知道了一点赶快就去向外国友人炫耀,我下面要提到的是黑人们自己都不喜欢听的,觉得这种偏见带有种族歧视成分。 我也不清楚这种说法是怎么来的,但是许多黑人被认为是喜欢吃炸鸡和西瓜。有没有任何事实根据,我也不清楚,但是在有些电影电视里你会看到这样的文化隐喻。黑人们自己并不喜欢这样的说法。我有一个黑人朋友,他告诉我说他曾经到一家类似咱们中国远郊边县的餐馆用餐,他叫了一杯冰水喝,但是侍应生却端来了一个大西瓜。全餐馆的白人都在哈哈大笑。我这个朋友告诉我说那是他一生中所受到的最大的耻辱。黑人也许和你开玩笑,提到他们自己喜欢吃西瓜和炸鸡,但是那不意味着你也可以开同样的玩笑。这就像妈妈可以说自己家的孩子有多么不好,但是别人的妈妈如果说自己孩子的不是,那么这个妈妈心里才叫一个赌气呢。同样的道理,给大家将这些事情的目的是让大家了解,然后能够听得懂,这就够了。要开种族的玩笑,就先拿自己开涮吧!美国人对英国人的“成见” 美国人对英国人的固有印象很多,但是有一点是特别有趣的。美国媒体特别喜欢嘲笑英国人的牙齿,觉得"Brits (British people) have bad teeth (英国人的牙齿都不怎么好)。我也不清楚这种讲法来自何处,我想其实在美国人眼里,只有他们自己的牙齿才是最齐、最白、最完美的。大家一笑而过吧! /200909/83529昆明医科大学第二附属医院治疗痘坑多少钱

昆医二附院做双眼皮开眼角手术多少钱德国作曲家巴赫“旧貌换新颜”Experts have digitally rebuilt the face of 18th century German composer Johann Sebastian Bach -- and say the results may surprise his fans.Using his bones and computer modeling, they have come up with an image of athick-setman with closely-shorn white hair.The new Bach face, the creation of Scottish forensic anthropologist Caroline Wilkinson, will go on display at the Bachhaus museum in the eastern German town of Eisenach, Bach's birthplace, next month.Eighteenth century portraits show him very differently. "For most people, Bach is an old man in a wig, it is a stylized image, we have no realistic portrait of him," Joerg Hansen, managing director of the museum said."We know he was a physical man, that he danced, that he stamped his feet when he played, that he sang. He was a very dynamic man -- with this reconstruction you can see it."Bach's bones were excavated in 1894 and sculptors first used them to help create a bust in 1908.But it was mainly based on a portrait of the composer and contemporary critics said it was so inaccurate that it might as well have been the composer Handel."It's not really that important to know what he looked like, we love Bach through his music, that is why people come to the museum, but they are also interested in the man," Hansen said. 近日,有关专家利用数字技术还原出18世纪德国著名作曲家约翰·塞巴斯蒂安·巴赫的容貌,并称这个新形象可能会让他的乐迷们大吃一惊。专家们利用巴赫的颅骨和计算机建模技术合成出了他的新形象。从新形象可以看出,巴赫体格健壮,留着一头短短的白发。巴赫的“新颜”出自苏格兰法医人类学家凯罗琳·威尔金森之手,并将于下月在巴赫出生地——东德小镇埃森纳赫的巴赫故居物馆展出。这个新形象与18世纪的巴赫画像差别很大。巴赫故居物馆馆长乔格·汉森说:“在多数人心目中,巴赫是一个戴着假发的老人,这是一个程式化的形象,其实我们并没有他的真实画像。”“我们知道,巴赫体格健壮,能唱能跳,演奏的时候还会跺着脚。他活力四射——这从他的新形象可以看出来。”巴赫的遗骨于1894年被掘出。1908年,雕塑家们首次利用这些遗骨塑造出了巴赫的半身雕像。但这尊塑像主要还是以巴赫的一副画像为样本,现代批评家们认为这尊塑像不够逼真,看上去倒是更像作曲家亨德尔。汉森说:“其实知道巴赫长什么样并不是那么重要,我们热爱巴赫主要是因为他的音乐,这也是人们来物馆参观的原因,不过人们对巴赫本人还是很感兴趣的。” /200803/30365昆明哪些美容院可以点痣 Mom and Dad: Thank you for everything this holiday season!爸爸妈妈:值此佳节,感谢您们所给予的一切。I'll be home to enjoy this Christmas with you.我将回家与你们共度佳节。A present from me is on the way.

安宁晋宁县激光去除雀斑费用你“Google”过自己吗?Have you ever "Googled" youself?More Americans are Googling themselves — and many are checking out their friends, co-workers and romantic interests, too.In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher."Yes it's doubled, but it's still the case that there's a big chunk of Internet users who have never done this simple act of plugging their name with search engines," she said.Americans under 50 and those with more education and income were more likely to self-Google — in some cases because their jobs demand a certain online persona.Meanwhile, Pew found that 53 percent of adult Internet users admit to looking up information about someone else, celebrities excluded.Often, it's to find someone they've lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.In many cases, the search is innocuous, done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies and divorce proceedings. A similar number have searched for someone else's photo.Few Internet users say they Google themselves regularly — about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate.Pew also found that teens were more likely than adults to restrict who can see their profiles at an online hangout like Facebook or News Corp.'s MySpace. 如今,越来越多的美国人在Google上搜索自己,还有很多人通过Google查找朋友、同事或约会对象的信息。Pew互联网和美国生活项目在上周日发布的一份调查报告中称,47%的美国成年互联网用户通过Google或其它搜索引擎查找过有关自己的信息。这一比例比2002年的22%增长了一倍多,但Pew调查中心的高级研究员玛丽#8226;麦登认为增幅还不够大。她说:“在Google上搜索自己的网民比例确实翻了一番,但调查同时显示,目前仍有很多网民从未用搜索引擎搜索过自己的名字。”年龄在50岁以下的美国人以及受教育程度和收入较高的人在Google上搜索自己的几率更大,这是因为他们的工作有时需要在网上公开个人信息。此外,Pew调查中心发现,53%的成年网民承认自己曾在Google上查找过除名人以外的其他人的信息。在很多情况下,人们这样做只是为了寻找失去联系的人,但也有很多人通过Google查找朋友、亲戚和邻居的信息。男性和女性网民在Google上搜索自己的人数比例差不多,但女性更爱在网上搜索约会对象的信息。在很多情况下,在网上搜索别人纯粹是为了找到此人的联系方式。但有三分之一的人这样做是为了了解别人的公共纪录,如破产及离婚纪录等。另有相同比例的人曾搜索过别人的照片。多数网民并不经常在Google上搜索自己——约四分之三的人称,他们仅搜索过一两次。多数人认为他们搜索到的有关自己的信息是正确的。该调查还发现,与成年人相比,青少年更希望限制别人在Facebook或Myspace等社交网站查看自己的个人信息。 /200803/32072 The brain can store a vast number of memories, so why can't we find these memories when we need to? A new study provides insights into this question.By Edward K. Vogel and Trafton DrewOur brains are crammed with a massive amount of memories that we have formed over a lifetime of experiences. These memories range from the profound (who am I and how did I get here?) to the most trivial (the license plate of the car at a stoplight). Furthermore, our memories also vary considerably in their precision. Parents, for instance, often know the perils of a fuzzy memory when shopping for a birthday gift for their child: remembering that their son wanted the G.I. Joe with Kung Fu Grip rather than the regular G.I. Joe could make an enormous difference in how well the gift is received. Thus, the “fuzziness” of our memory can often be just as important in our daily lives as being able to remember lots and lots of information in the first place.Different Levels of Detail for Different Types of Memory?In the past several decades, cognitive psychologists have determined that there are two primary memory systems in the human mind: a short-term, or “working,” memory that temporarily holds information about just a few things that we are currently thinking about; and a long-lasting memory that can hold massive amounts of information gained through a lifetime of thoughts and experiences. These two memory systems are also thought to differ in the level of detail they provide: working memory provides sharp detail about the few things we are presently thinking about, whereas long-term memory provides a much fuzzier picture about lots of different things we have seen or experienced. That is, although we can hold lots of things in long-term memory, the details of the memory aren’t always crystal-clear and are often limited to just the gist of what we saw or what happened.A recently published study by Timothy F. Brady, a cognitive neuroscientist at the Massachusetts Institute of Technology, and colleagues suggests that these long-term memories may not be nearly as fuzzy as once thought, however. In their work, the researchers asked subjects to try to remember 3,000 pictures of common objects—including items such as backpacks, remote controls and toasters—that were presented one at a time for just a few seconds each. At the end of this viewing phase, the researchers tested subjects’ memory for each object by showing them two objects and asking which one they had seen before. Not surprisingly, subjects were exceptionally good (more than 90 percent correct) even though there were thousands of objects to remember. This high success rate attests to the massive storage ability of long-term memory. What was most surprising, however, was the amazing level of detail that the subjects had for all of these memories. The subjects were just as good at telling the difference between two pictures of the same object even when the objects differed in an extremely subtle manner, such as a pair of toasters with slightly different slices of b.If It’s Not Fuzzy, Why Do We Still Forget Things?This new work provides compelling evidence that the enormous amount of information we hold in long-term memory is not so uncertain after all. It seems that we actually hold representations of things we’ve seen in a fairly detailed and precise form.Of course, this finding raises the obvious question: if our memories aren’t all that fuzzy, then why do we often forget the details of things we want to remember? One explanation is that, although the brain contains detailed representations of lots of different events and objects, we can’t always find that information when we want it. As this study reveals, if we’re shown an object, we can often be very accurate and precise at being able to say whether we’ve seen it before. If we’re in a toy store and trying to remember what it was that our son wanted for his birthday, however, we need to be able to voluntarily search our memory for the right answer—without being prompted by a visual reminder. It seems that it is this voluntary searching mechanism that’s prone to interference and forgetfulness. At least that’s our story when we come home without the Kung Fu Grip G.I. Joe.Are you a scientist? Have you recently a peer-reviewed paper that you want to write about? Then contact Mind Matters editor Jonah Lehrer, the science writer behind the blog The Frontal Cortex and the book Proust Was a Neuroscientist. 大脑能够储存巨大数量的记忆,那么为什么在需要的时候我们会回忆不起来呢? 一项新的研究为这一问题提供了见解。作者Edward K. Vogel and Trafton Drew我们的大脑里填满了在我们整个人生经历中形成的大量记忆。 这些记忆可以很深奥(我是谁还有我怎么来到这的?)也可以是最琐碎的(红灯停车时看到的某辆车的牌照)。 此外,我们记忆的准确度在相当程度上也存在着分别。 打个比方,父母们大多都明白在给他们的孩子买一份生日礼物时,如果记忆不清楚会有什么不良后果。 记得他们的孩子更想要的是耍功夫把式的G.I. Joe(眼镜蛇部队),而非普通的G.I. Joe,会显著影响孩子接受礼物的乐意程度。 因此,在日常生活的大多数情况下,我们记忆的“模糊性”与一开始就能够记住很多很多信息是同等重要的。不同类型的记忆有不同的细节水平?过去的几十年中,认知心理学家们已经确定,在人类大脑中主要存在着两种记忆系统。 一种短期的,或者“工作”的记忆短暂地储存了我们正在想着的少数事情的信息;另一种长期的记忆能够储存通过一生思考和经历得到的海量信息。 在提供细节的水平上,这两种记忆也被认为是不同的。 工作记忆给出的是有关我们当前正在思考的少数事情的清晰细节,而长期记忆给出的则是有关我们曾经见过或经历过的大量事情的,更加模糊的图像。 这就是说,虽然我们在长期记忆中储存了很多东西,但其记忆细节并不总是清晰透彻,而是经常只限于我们所见或已发生事情的要点梗概。然而,在最近发表的一项研究中,麻省理工学院认知神经学家蒂莫西·布莱迪及其同事们提出,这些长期记忆并非如之前所认为的那么模糊。 研究中,研究人员要求实验者们尝试记住3000幅普通物件的图片——包括如背包、遥控器和烤面包片机等物品——一张每次就看几秒钟。 观看环节结束时,研究人员考察了实验者的记忆:向他们展示了两个物品,并问哪一个是之前见过的。 毫无意外,实验者们的表现格外优秀(超过90%正确),尽管要记住的有数千件物品。 如此高的成功率应了长期记忆的巨大存储能力。 然而,最出乎意料的是,实验者们的这些记忆中表现出来的令人惊异的细节水平。 实验者们在区分两张同种物品的图片之间的差别上做的相当不错,即便这种区别极其细微,例如两个只在所放面包薄片上差别微小的烤面包片机。如果并不模糊,为什么我们仍然忘记事情?我们在长期记忆中储存的大量信息归根到底并不是那么不确定的,这项新研究为此提供了引人注目的据。 看起来,我们对曾见过事情的再现实际上是相当详细和精确的。当然,这项发现也提出了显而易见的问题。 如果我们的记忆并非都那么模糊,那为什么我们老是忘记我们所要记住事物的细节呢? 一个解释是,尽管大脑保存了大量不同事件和物品的细节表象,但我们并不是总能在需要的时候把那信息找出来。 就如这次研究所显示的,如果给我们看一个物品,我们大多能够非常精确、准确无误地说出我们之前是否见过它。 然而如果当我们身在玩具店,试着记起儿子想要的生日礼物是什么样的时候,我们就需要能够自动地在记忆中搜索正确——而不是受到视觉上能提醒你的物品的推动。 看来,似乎是这个自动的搜索机制使我们易于受到干扰和健忘。 至少这也是我们没有带着耍功夫的眼镜蛇部队回家的一个借口。 /200811/55456昆明哪个医院可打廋脸针石林寻甸禄劝唇部激光脱毛价格
