Multitasking is part of daily life. But humans remember and learn differently when their attention is divided. Russel Poldrack, a UCLA psychology professor, speaks with Lynn Neary about what occurs in the brain during multitasking.

the best way to know you have a mind is to change it

if you worry about what others think of you, you will be living their version of your life and not yours.

大脑就是一台三磅重的超级计算机。它是身体运行的命令和控制中心。它几乎涉及你所做的每一件事。你的大脑决定你如何思考，如何感觉，如何行动，以及如何与他人相处。你的大脑甚至决定你是哪一类的人。它决定了你有多善解人意；你有多友善或是有多粗鲁。它决定了你思维有多敏捷，这还涉及到你工作完成的如何以及你的家庭。你的大脑还影响你的情感活动，以及你如何对待异性。

Could a mainland paper run a satirical opinion piece saying that Hu Jintao was doing a bad job? "No, because it would be untrue," he said. "But what if the article was all factually true? There were no false statistics, no misspelled names, no wrong dates. But an opinion that Hu was handling things badly?" "But he IS doing a good job," my Chinese friend said. The point was not whether he or I personally thought Hu was doing a good job; but whether someone could express the opinion that he wasn't. "No," my Chinese friend said. "If, hypothetically, Hu really did something factually, provably wrong -- like he was being tried for corruption -- that could be reported."

Cindi Rigsbee, for example, makes sure her students know when text language is appropriate and, more important, when it's not. She talks frequently in class about types of writing, the intended reader, and the evolution of language. At the beginning of each school year, she introduces a discussion about the way English has transformed over time. "We look at Old English, Middle English, and what was contemporary English in the time of Jane Eyre. Then I show them a MySpace page."

The government now faces a tricky predicament: Having loosened its restraints on information flow this time, a return to its old ways at the next sign of difficulty could backfire. “The government should learn a positive lesson: When it allows freer information flow it is better for its image and legitimacy,” Mr. Xiao said. “But this will not always be a case, especially if the next crisis is man-made

China’s online censors can be merciless in their deletion of blog postings or forum comments that are deemed “too sensitive,” particularly involving anything to do with the so-called “Three T’s”: Tiananmen, Tibet and Taiwan. Post-earthquake negativity, though, has been tolerated. “Nine billion yuan [$1.3 billion] has been raised but how much will actually get to the disaster zone?” one skeptical commenter asked on a forum on Baidu, China’s leading search engine. Discussions focusing on discrepancies between the amount of donations declared by the Chinese Red Cross and the corresponding numbers issued by the Ministry of Civil Affairs also have met with minimal interference, Mr. Kennedy said. However, the government has not turned a blind eye. More than a dozen people have been arrested for “spreading rumors” online, and political blogger Guo Quan was detained for questioning the risks posed by cracked dams and damaged nuclear facilities.

In July, 2001, after arriving in Beijing, Adelson and Weidner saw Olympic banners flying along the streets. They soon learned that the country was waiting to find out whether it would be selected as the site for the 2008 Summer Games. In addition to seeing the Vice-Premier, Adelson and Weidner met with the mayor of Beijing, who asked Adelson for help with a matter pending in the U.S. House of Representatives, which he believed was threatening China’s chance to host the Olympics. (In the United States, China was widely perceived as the frontrunner, and it is not clear that Congress’s position would have had any impact on its chances.) Adelson said in court that he immediately made calls on his cell phone to Republican friends in Congress—including Tom DeLay, then the majority whip—who had received generous support from Adelson. DeLay told him that there was indeed a resolution pending about China and the Olympics. (Representative Tom Lantos, then the highest-ranking Democrat on the House International Relations Committee, had introduced a resolution opposing China’s Olympic bid, saying, “China’s abominable human rights record violates the spirit of the games and should disqualify Beijing from consideration.”)

Learning how to turn a flashlight into a laser is not a top priority for most people. Yet Kip Kedersha’s step-by-step instructional video that teaches how to do just that has been seen online by more people (1.88 million) than live in Manhattan (about 1.6 million).

Message on the Twentieth Anniversary of Tiananmen SquareHillary Rodham Clinton Secretary of State Washington, DC June 3, 2009On this the 20th anniversary of the violent suppression of demonstrations in Tiananmen Square by Chinese authorities, we should remember the tragic loss of hundreds of innocent lives and reflect upon the meaning of the events that preceded that day. Hundreds of thousands of protesters took to the streets for weeks, in Beijing and around the country, first to honor the late reformist leader Hu Yaobang and then to demand basic rights denied to them.A China that has made enormous progress economically, and that is emerging to take its rightful place in global leadership, should examine openly the darker events of its past and provide a public accounting of those killed, detained or missing, both to learn and to heal. This anniversary provides an opportunity for Chinese authorities to release from prison all those still serving sentences in connection with the events surrounding June 4, 1989. We urge China to cease the harassment of participants in the demonstrations and begin dialogue with the family members of victims, including the Tiananmen Mothers. China can honor the memory of that day by moving to give the rule of law, protection of internationally-recognized human rights, and democratic development the same priority as it has given to economic reform.

Suppose scientists could erase certain memories by tinkering with a single substance in the brain. Could make you forget a chronic fear, a traumatic loss, even a bad habit.

Researchers in Brooklyn have recently accomplished comparable feats, with a single dose of an experimental drug delivered to areas of the brain critical for holding specific types of memory, like emotional associations, spatial knowledge or motor skills.

The drug blocks the activity of a substance that the brain apparently needs to retain much of its learned information.

What can Facebook and Western social networks learn, if anything? If monetizing a social network is so easy, then why hasn’t Facebook opened up its payment API to third party developers? While the aggressive and intrusive hyper-viral aspects of the apps in China may not be replicable in a Western Market, the problems for creating a more viable business model run deeper. Western companies cannot innovate in the same way due to institutional problems stemming from their own struggle for an identity and revenue. Facebook has just recently announced a “credits” system, but it seems to miss the mark. The new system demonstrates little incentive for users to shell over money, and does not speak to the same need as paying for a social application that all your friends are already on and talking about. Facebook may be afraid to become a marketplace for applications, because they are reluctant to be labeled as a social gaming network or a social app store. Instead, they are a self-styled guru of dynamic human interaction. If they opened up their platform to become an apps store, their major revenue streams would put them into a pigeonhole, calling their $15 billion valuation into question. They obviously don’t want to be labeled as a “gaming platform” either, and don’t want to fully depend on selling digital trinkets. Like during the American gold rush in 1849, where Chinese merchants prospered while most prospectors went bust in search of striking gold, it appears that building viable, scalable businesses for Social Networking sites may still be an ancient Chinese secret for Westerners.
