"Reports from Philippine capital say former police officer has been killed"

News or entertainment? Or is there no longer a difference? Was there ever?

"Earlier this year, AC360°, with the help of a seasoned team of researchers, conducted a pilot study based on the 1940's doll test. In this pilot study, more than 130 kids were asked a series of questions about five cartoon dolls with varying skin tones. Half of the children were African-American and half were white, half were in the north and half in the south. The results were surprising: white children have an overwhelming white bias, and black children also have a bias toward white. "

Where does racism come from...nature or nurture?

"Professor Philip Zimbardo conveys how our individual perspectives of time affect our work, health and well-being. Time influences who we are as a person, how we view relationships and how we act in the world."

"While there is no precise count, some experts believe New York is home to as many as 800 languages - far more than the 176 spoken by students in the city's public schools or the 138 that residents of Queens, New York's most diverse borough, listed on their 2000 census forms.\n\n"It is the capital of language density in the world," said Daniel Kaufman, an adjunct professor of linguistics at the Graduate Center of the City University of New York. "We're sitting in an endangerment hot spot where we are surrounded by languages that are not going to be around even in 20 or 30 years." "

"In recent decades, the study of language acquisition and instruction has increasingly focused on "chunking": how children learn language not so much on a word-by-word basis but in larger "lexical chunks" or meaningful strings of words that are committed to memory. Chunks may consist of fixed idioms or conventional speech routines, but they can also simply be combinations of words that appear together frequently, in patterns that are known as "collocations." In the 1960s, the linguist Michael Halliday pointed out that we tend to talk of "strong tea" instead of "powerful tea," even though the phrases make equal sense. Rain, on the other hand, is much more likely to be described as "heavy" than "strong." "

Part 1 of a 4-part series examining what happens when science is used for marketing (using brain-training software as the central example). Almost all of the programs that tout their ability to train your brain are limited in scope. Most train your ability to perform simple cognitive tasks by having you perform them repeatedly, often adapting the difficulty of the task over time to keep it challenging. Some determine which tasks you perform well and which need improvement and adjust the tasks based on your ongoing performance. The simplest ones, though, simply track how much you improve and inform you that such improvements have made increased the fitness of your brain. Such task-specific training effects can be really useful-if you want to enhance your ability to do Sudoku, by all means practice doing Sudoku. But what pitches for those programs regularly imply is that playing their videogame or using their training will enhance your ability to do other tasks that weren't specifically trained. For example, this advertisement for Nintendo's Brain Age implies that by using their game, you will be better able to remember your friend's name when you meet him on the street. The idea that playing games can improve your brain is pervasive, and it taps what Chris Chabris and I have called the "illusion of potential." A common myth of the mind is that we have vast pools of untapped mental resources that can be released with relatively minimal effort. This common intuitive belief underlies the pervasive myth that we only use 10% of our brains, that listening to Mozart can increase our IQ [pdf], and even the belief that some people have "discovered" psychic abilities. We devote the last main chapter of The Invisible Gorilla to this belief and its ramifications, and we recently wrote a column for the NY Times discussing how popular self-help books like The Secret and The Power capitalize on this mistaken belief. The marketing for some brain training programs

"As people have become more and more dependent on the Internet, some have concerns that all that information (and the devices that help us connect to it) could be doing seriously damage to the way we think, interact and learn. But Nick Bilton, lead writer for the New York Times Bits Blog, explains in his new book that he's lived his whole life connected and managed to turn out just fine. He says scientific research backs up his experience."

Indianapolis Public Schools retained 8.4% of its kindergarten students last year, and some educators are debating the effectiveness of having students repeat kindergarten. Some say tougher standards are trickling down to the lower grades and that students need to master certain skills to move on to first grade. But others say there are few long-term benefits of holding back kindergartners and that the practice increases negative attitudes about school as well as the likelihood that a student will eventually drop out.

"About this time every year, with the fall marathon season at its zenith, racers in training begin to hear the refrain, ''You are going to ruin your knees.''"

"Babble is increasingly being understood as an essential precursor to speech, and as a key predictor of both cognitive and social emotional development. And research is teasing apart the phonetic components of babble, along with the interplay of neurologic, cognitive and social factors. "

"Why do economists argue at all? Given that Fed members and economists are looking at the same data, and given the reams of evidence accumulated over decades - not to mention a few centuries of great minds, great theories and thick books that preceded this crisis - why isn't a right answer self-evident? "

From sociology to mathematics, the academic world as viewed through the lens of "purity."

Thanks to Catherine T. (Oberlin Class of 2014) for this one.

"The economic forecasts are in for 2010, and there are mixed views about whether the economy will turn the corner this year. The consensus among leading economists is for 2.7 percent growth this year. A lot goes in to forecasting the economy and getting the math right is only one of them."

"THE Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association, is the bible of diagnosis in psychiatry, and is used not just by doctors around the world but also by health insurers. Changing any such central document is complicated. It should therefore come as no surprise that a committee of experts charged with revising the manual has caused consternation by considering removing Asperger syndrome from the next edition, scheduled to appear in 2012. The committee argues that the syndrome should be deleted because there is no clear separation between it and its close neighbor, autism. "

"There are lots of expectations and assumptions about how birth order may shape our adult lives, and many of them go back ages. Centuries ago, the oldest son had huge incentives to stay on track and live up to family expectations - that's because, by tradition, he was set to inherit almost everything. "Historically the practice of primogeniture was very common in Europe," says Frank Sulloway, a visiting scholar at the Institute of Personality and Social Research at the University of California, Berkeley. "So firstborns had every reason to preserve the status quo and be on good terms with their parents. Now you may think any "first born" effect would have completely disappeared in modern times. But not so, say experts who study birth order. Researchers first examined the status of firstborns among Washington power brokers in 1972."

"Separating anatomy from what it means to be a man or a woman, New York City is moving forward with a plan to let people alter the sex on their birth certificate even if they have not had sex-change surgery. Under the rule being considered by the city's Board of Health, which is likely to be adopted soon, people born in the city would be able to change the documented sex on their birth certificates by providing affidavits from a doctor and a mental health professional laying out why their patients should be considered members of the opposite sex, and asserting that their proposed change would be permanent. Applicants would have to have changed their name and shown that they had lived in their adopted gender for at least two years, but there would be no explicit medical requirements."

"Economics aspires to be a science. But in this it does not succeed. Neither does finance. This despite the fact that there is an annual, optimistically named Nobel Prize in "Economic Sciences." Financial crises keep happening-the list is long. Could they be avoided if economics and finance were science? To paraphrase financial observer James Grant: science is progressive, but finance is cyclical. But why should this be? Do we not learn from experience? Does economic knowledge not increase? And how about having computers, vast amounts of data and information, and new mathematical models to guide lending and investing decisions?"

"As a fitness coach in Grand Rapids, Mich., Doreen Bolhuis has a passion for developing exercises for children. The younger, it seems, the better. "With the babies in our family," she said, "I start working them out in the hospital." Ms. Bolhuis turned her exercises into a company, Gymtrix, that offers a library of videos starting with training for babies as young as 6 months. There is no lying in the crib playing with toes. Infant athletes, accompanied by doting parents on the videos, do a lot of jumping, kicking and, in one exercise, something that looks like baseball batting practice. "We hear all the time from families that have been with us, 'Our kids are superstars when they're in middle school and they get into sports,' " Ms. Bolhuis said. Future Robinson Canos and Sidney Crosbys are getting their start in sports earlier than ever. Kindergartners play in soccer leagues and at an annual T-Ball World Series in Milton, Fla. But now children are being groomed as athletes before they can walk. The growing competition in marketing baby sports DVDs includes companies with names like athleticBaby and Baby Goes Pro. Even experts in youth sports seem startled that the age of entry has dipped so low. "That's really amazing. What's next?" said Dr. Lyle Micheli, an orthopedic surgeon and founder of the first pediatric sports medicine clinic in the United States at Children's Hospital in Boston. Dr. Micheli said he did not see any great advantages in exposing babies to sports. "I don't know of any evidence that training at this infancy stage accelerates coordination," he said. One of his concerns, he said, is "the potential for even younger ages of overuse injury." Bob Bigelow, a former National Basketball Association player and a critic of competitive sports for young children, is also skeptical. "This is Baby Mozart stuff; you play Mozart for the baby in utero and it comes out some sort of fine arts major," he said. â€
