The Creativity Crisis


For the first time, research shows that American creativity is declining. What went wrong—and how we can fix it.


Back in 1958, Ted Schwarzrock was an 8-year-old third grader when he became one of the “Torrance kids,” a group of nearly 400 Minneapolis children who completed a series of creativity tasks newly designed by professor E. Paul Torrance. Schwarzrock still vividly remembers the moment when a psychologist handed him a fire truck and asked, “How could you improve this toy to make it better and more fun to play with?” He recalls the psychologist being excited by his answers. In fact, the psychologist’s session notes indicate Schwarzrock rattled off 25 improvements, such as adding a removable ladder and springs to the wheels. That wasn’t the only time he impressed the scholars, who judged Schwarzrock to have “unusual visual perspective” and “an ability to synthesize diverse elements into meaningful products.”

The accepted definition of creativity is production of something original and useful, and that’s what’s reflected in the tests. There is never one right answer. To be creative requires divergent thinking (generating many unique ideas) and then convergent thinking (combining those ideas into the best result).

In the 50 years since Schwarzrock and the others took their tests, scholars—first led by Torrance, now his colleague, Garnet Millar—have been tracking the children, recording every patent earned, every business founded, every research paper published, and every grant awarded. They tallied the books, dances, radio shows, art exhibitions, software programs, advertising campaigns, hardware innovations, music compositions, public policies (written or implemented), leadership positions, invited lectures, and buildings designed.
Nobody would argue that Torrance’s tasks, which have become the gold standard in creativity assessment, measure creativity perfectly. What’s shocking is how incredibly well Torrance’s creativity index predicted those kids’ creative accomplishments as adults. Those who came up with more good ideas on Torrance’s tasks grew up to be entrepreneurs, inventors, college presidents, authors, doctors, diplomats, and software developers. Jonathan Plucker of Indiana University recently reanalyzed Torrance’s data. The correlation to lifetime creative accomplishment was more than three times stronger for childhood creativity than childhood IQ.

Like intelligence tests, Torrance’s test—a 90-minute series of discrete tasks, administered by a psychologist—has been taken by millions worldwide in 50 languages. Yet there is one crucial difference between IQ and CQ scores. With intelligence, there is a phenomenon called the Flynn effect—each generation, scores go up about 10 points. Enriched environments are making kids smarter. With creativity, a reverse trend has just been identified and is being reported for the first time here: American creativity scores are falling.

Kyung Hee Kim at the College of William & Mary discovered this in May, after analyzing almost 300,000 Torrance scores of children and adults. Kim found creativity scores had been steadily rising, just like IQ scores, until 1990. Since then, creativity scores have consistently inched downward. “It’s very clear, and the decrease is very significant,” Kim says. It is the scores of younger children in America—from kindergarten through sixth grade—for whom the decline is “most serious.

The potential consequences are sweeping. The necessity of human ingenuity is undisputed. A recent IBM poll of 1,500 CEOs identified creativity as the No. 1 “leadership competency” of the future. Yet it’s not just about sustaining our nation’s economic growth. All around us are matters of national and international importance that are crying out for creative solutions, from saving the Gulf of Mexico to bringing peace to Afghanistan to delivering health care. Such solutions emerge from a healthy marketplace of ideas, sustained by a populace constantly contributing original ideas and receptive to the ideas of others.

It’s too early to determine conclusively why U.S. creativity scores are declining. One likely culprit is the number of hours kids now spend in front of the TV and playing videogames rather than engaging in creative activities. Another is the lack of creativity development in our schools. In effect, it’s left to the luck of the draw who becomes creative: there’s no concerted effort to nurture the creativity of all children.

Around the world, though, other countries are making creativity development a national priority. In 2008 British secondary-school curricula—from science to foreign language—was revamped to emphasize idea generation, and pilot programs have begun using Torrance’s test to assess their progress. The European Union designated 2009 as the European Year of Creativity and Innovation, holding conferences on the neuroscience of creativity, financing teacher training, and instituting problem-based learning programs—curricula driven by real-world inquiry—for both children and adults. In China there has been widespread education reform to extinguish the drill-and-kill teaching style. Instead, Chinese schools are also adopting a problem-based learning approach.

Plucker recently toured a number of such schools in Shanghai and Beijing. He was amazed by a boy who, for a class science project, rigged a tracking device for his moped with parts from a cell phone. When faculty of a major Chinese university asked Plucker to identify trends in American education, he described our focus on standardized curriculum, rote memorization, and nationalized testing. “After my answer was translated, they just started laughing out loud,” Plucker says. “They said, ‘You’re racing toward our old model. But we’re racing toward your model, as fast as we can.’ ”

Overwhelmed by curriculum standards, American teachers warn there’s no room in the day for a creativity class. Kids are fortunate if they get an art class once or twice a week. But to scientists, this is a non sequitur, borne out of what University of Georgia’s Mark Runco calls “art bias.” The age-old belief that the arts have a special claim to creativity is unfounded. When scholars gave creativity tasks to both engineering majors and music majors, their scores laid down on an identical spectrum, with the same high averages and standard deviations. Inside their brains, the same thing was happening—ideas were being generated and evaluated on the fly.

Researchers say creativity should be taken out of the art room and put into homeroom. The argument that we can’t teach creativity because kids already have too much to learn is a false trade-off. Creativity isn’t about freedom from concrete facts. Rather, fact-finding and deep research are vital stages in the creative process. Scholars argue that current curriculum standards can still be met, if taught in a different way.

To understand exactly what should be done requires first understanding the new story emerging from neuroscience. The lore of pop psychology is that creativity occurs on the right side of the brain. But we now know that if you tried to be creative using only the right side of your brain, it’d be like living with ideas perpetually at the tip of your tongue, just beyond reach.

When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions.

Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with.

Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.

Is this learnable? Well, think of it like basketball. Being tall does help to be a pro basketball player, but the rest of us can still get quite good at the sport through practice. In the same way, there are certain innate features of the brain that make some people naturally prone to divergent thinking. But convergent thinking and focused attention are necessary, too, and those require different neural gifts. Crucially, rapidly shifting between these modes is a top-down function under your mental control. University of New Mexico neuroscientist Rex Jung has concluded that those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better. A lifetime of consistent habits gradually changes the neurological pattern.

A fine example of this emerged in January of this year, with release of a study by University of Western Ontario neuroscientist Daniel Ansari and Harvard’s Aaron Berkowitz, who studies music cognition. They put Dartmouth music majors and nonmusicians in an fMRI scanner, giving participants a one-handed fiber-optic keyboard to play melodies on. Sometimes melodies were rehearsed; other times they were creatively improvised. During improvisation, the highly trained music majors used their brains in a way the nonmusicians could not: they deactivated their right-temporoparietal junction. Normally, the r-TPJ reads incoming stimuli, sorting the stream for relevance. By turning that off, the musicians blocked out all distraction. They hit an extra gear of concentration, allowing them to work with the notes and create music spontaneously.

Charles Limb of Johns Hopkins has found a similar pattern with jazz musicians, and Austrian researchers observed it with professional dancers visualizing an improvised dance. Ansari and Berkowitz now believe the same is true for orators, comedians, and athletes improvising in games.

The good news is that creativity training that aligns with the new science works surprisingly well. The University of Oklahoma, the University of Georgia, and Taiwan’s National Chengchi University each independently conducted a large-scale analysis of such programs. All three teams of scholars concluded that creativity training can have a strong effect. “Creativity can be taught,” says James C. Kaufman, professor at California State University, San Bernardino.

What’s common about successful programs is they alternate maximum divergent thinking with bouts of intense convergent thinking, through several stages. Real improvement doesn’t happen in a weekend workshop. But when applied to the everyday process of work or school, brain function improves.

So what does this mean for America’s standards-obsessed schools? The key is in how kids work through the vast catalog of information. Consider the National Inventors Hall of Fame School, a new public middle school in Akron, Ohio. Mindful of Ohio’s curriculum requirements, the school’s teachers came up with a project for the fifth graders: figure out how to reduce the noise in the library. Its windows faced a public space and, even when closed, let through too much noise. The students had four weeks to design proposals.

Working in small teams, the fifth graders first engaged in what creativity theorist Donald Treffinger describes as fact-finding. How does sound travel through materials? What materials reduce noise the most? Then, problem-finding—anticipating all potential pitfalls so their designs are more likely to work. Next, idea-finding: generate as many ideas as possible. Drapes, plants, or large kites hung from the ceiling would all baffle sound. Or, instead of reducing the sound, maybe mask it by playing the sound of a gentle waterfall? A proposal for double-paned glass evolved into an idea to fill the space between panes with water. Next, solution-finding: which ideas were the most effective, cheapest, and aesthetically pleasing? Fiberglass absorbed sound the best but wouldn’t be safe. Would an aquarium with fish be easier than water-filled panes?

Then teams developed a plan of action. They built scale models and chose fabric samples. They realized they’d need to persuade a janitor to care for the plants and fish during vacation. Teams persuaded others to support them—sometimes so well, teams decided to combine projects. Finally, they presented designs to teachers, parents, and Jim West, inventor of the electric microphone.

Along the way, kids demonstrated the very definition of creativity: alternating between divergent and convergent thinking, they arrived at original and useful ideas. And they’d unwittingly mastered Ohio’s required fifth-grade curriculum—from understanding sound waves to per-unit cost calculations to the art of persuasive writing. “You never see our kids saying, ‘I’ll never use this so I don’t need to learn it,’ ” says school administrator Maryann Wolowiec. “Instead, kids ask, ‘Do we have to leave school now?’ ” Two weeks ago, when the school received its results on the state’s achievement test, principal Traci Buckner was moved to tears. The raw scores indicate that, in its first year, the school has already become one of the top three schools in Akron, despite having open enrollment by lottery and 42 percent of its students living in poverty.

With as much as three fourths of each day spent in project-based learning, principal Buckner and her team actually work through required curricula, carefully figuring out how kids can learn it through the steps of Treffinger’s Creative Problem-Solving method and other creativity pedagogies. “The creative problem-solving program has the highest success in increasing children’s creativity,” observed William & Mary’s Kim.

The home-game version of this means no longer encouraging kids to spring straight ahead to the right answer. When UGA’s Runco was driving through California one day with his family, his son asked why Sacramento was the state’s capital—why not San Francisco or Los Angeles? Runco turned the question back on him, encouraging him to come up with as many explanations as he could think of.

Preschool children, on average, ask their parents about 100 questions a day. Why, why, why—sometimes parents just wish it’d stop. Tragically, it does stop. By middle school they’ve pretty much stopped asking. It’s no coincidence that this same time is when student motivation and engagement plummet. They didn’t stop asking questions because they lost interest: it’s the other way around. They lost interest because they stopped asking questions.

Having studied the childhoods of highly creative people for decades, Claremont Graduate University’s Mihaly Csikszentmihalyi and University of Northern Iowa’s Gary G. Gute found highly creative adults tended to grow up in families embodying opposites. Parents encouraged uniqueness, yet provided stability. They were highly responsive to kids’ needs, yet challenged kids to develop skills. This resulted in a sort of adaptability: in times of anxiousness, clear rules could reduce chaos—yet when kids were bored, they could seek change, too. In the space between anxiety and boredom was where creativity flourished.

It’s also true that highly creative adults frequently grew up with hardship. Hardship by itself doesn’t lead to creativity, but it does force kids to become more flexible—and flexibility helps with creativity.

In early childhood, distinct types of free play are associated with high creativity. Preschoolers who spend more time in role-play (acting out characters) have higher measures of creativity: voicing someone else’s point of view helps develop their ability to analyze situations from different perspectives. When playing alone, highly creative first graders may act out strong negative emotions: they’ll be angry, hostile, anguished. The hypothesis is that play is a safe harbor to work through forbidden thoughts and emotions.

In middle childhood, kids sometimes create paracosms—fantasies of entire alternative worlds. Kids revisit their paracosms repeatedly, sometimes for months, and even create languages spoken there. This type of play peaks at age 9 or 10, and it’s a very strong sign of future creativity. A Michigan State University study of MacArthur “genius award” winners found a remarkably high rate of paracosm creation in their childhoods.

From fourth grade on, creativity no longer occurs in a vacuum; researching and studying become an integral part of coming up with useful solutions. But this transition isn’t easy. As school stuffs more complex information into their heads, kids get overloaded, and creativity suffers. When creative children have a supportive teacher—someone tolerant of unconventional answers, occasional disruptions, or detours of curiosity—they tend to excel. When they don’t, they tend to underperform and drop out of high school or don’t finish college at high rates.

They’re quitting because they’re discouraged and bored, not because they’re dark, depressed, anxious, or neurotic. It’s a myth that creative people have these traits. (Those traits actually shut down creativity; they make people less open to experience and less interested in novelty.) Rather, creative people, for the most part, exhibit active moods and positive affect. They’re not particularly happy—contentment is a kind of complacency creative people rarely have. But they’re engaged, motivated, and open to the world.

The new view is that creativity is part of normal brain function. Some scholars go further, arguing that lack of creativity—not having loads of it—is the real risk factor. In his research, Runco asks college students, “Think of all the things that could interfere with graduating from college.” Then he instructs them to pick one of those items and to come up with as many solutions for that problem as possible. This is a classic divergent-convergent creativity challenge. A subset of respondents, like the proverbial Murphy, quickly list every imaginable way things can go wrong. But they demonstrate a complete lack of flexibility in finding creative solutions. It’s this inability to conceive of alternative approaches that leads to despair. Runco’s two questions predict suicide ideation—even when controlling for preexisting levels of depression and anxiety.

In Runco’s subsequent research, those who do better in both problem-finding and problem-solving have better relationships. They are more able to handle stress and overcome the bumps life throws in their way. A similar study of 1,500 middle schoolers found that those high in creative self-efficacy had more confidence about their future and ability to succeed. They were sure that their ability to come up with alternatives would aid them, no matter what problems would arise.

When he was 30 years old, Ted Schwarzrock was looking for an alternative. He was hardly on track to becoming the prototype of Torrance’s longitudinal study. He wasn’t artistic when young, and his family didn’t recognize his creativity or nurture it. The son of a dentist and a speech pathologist, he had been pushed into medical school, where he felt stifled and commonly had run-ins with professors and bosses. But eventually, he found a way to combine his creativity and medical expertise: inventing new medical technologies.

Today, Schwarzrock is independently wealthy—he founded and sold three medical-products companies and was a partner in three more. His innovations in health care have been wide ranging, from a portable respiratory oxygen device to skin-absorbing anti-inflammatories to insights into how bacteria become antibiotic-resistant. His latest project could bring down the cost of spine-surgery implants 50 percent. “As a child, I never had an identity as a ‘creative person,’ ” Schwarzrock recalls. “But now that I know, it helps explain a lot of what I felt and went through.”

Creativity has always been prized in American society, but it’s never really been understood. While our creativity scores decline unchecked, the current national strategy for creativity consists of little more than praying for a Greek muse to drop by our houses. The problems we face now, and in the future, simply demand that we do more than just hope for inspiration to strike. Fortunately, the science can help: we know the steps to lead that elusive muse right to our doors.

Friday 9 July 2010

A sophisticated new analysis of team tactics predicts a Spanish win in Sunday's FIFA World Cup final and also shows why England were beaten by Germany.
Mathematicians and football supporters Dr Javier López Peña and Dr Hugo Touchette from Queen Mary, University of London have collected ball passing data from all of the FIFA World Cup games and analysed it to reveal the nations' different styles of play.
Using the mathematical technique called Graph Theory, they have revealed the gaping holes in England's tactics against Germany game and made predictions about the Netherlands-Spain final that could rival the psychic octopus.
For each national side, Drs López Peña and Touchette have drawn up a 'network' of passes between players throughout the tournament and analysed how these networks compare between teams. Dr Touchette explains: "Each player in the network is given a score called centrality which measures how vital they are to the network. The higher the centrality score, the bigger the impact if that player wasn't there. This method is most commonly used to make computer networks more robust, but it can also be used to plan football strategy."
Graph Theory is used to analyse different types of network, most commonly to investigate computer networks - such as the internet - and to model what would happen if different parts of the networks were suddenly removed. This type of research, which takes place in Queen Mary's School of Mathematical Sciences, can make computer networks more robust and less susceptible to disruption.

The networks reveal Spanish players have made a strikingly high number of passes this tournament, almost 40 per cent more than Germany and twice as many as the Dutch. "The team relies on swift passes that are well distributed among all players, especially between those playing mid-field," said Dr López Peña.
David Villa, the tournament's highest goal scorer, has received an average of 37 passes per game, more than any other forward from all the teams. Dr López Peña said: "Villa's performance has been impressive compared with Fernando Torres, who has not scored any goals this tournament. This was reflected in the successful Spanish tactics, with Torres only receiving an average of 13 passes per match, and 37 to Villa."
Conversely, the Dutch gameplay is clearly offensive, involving a very low number of passes between players, most of which are aimed at the strikers. Dr López Peña said: "The low number of passes shows the Dutch prefer quick attacks and counterstrikes rather than intricate playing. Their goals are often scored from set pieces such as free kicks and they use their physical presence to beat their opponents."

The analysis shows the English squad to have a balanced line-up with no single player more important than the team as a whole. Dr López Peña said: "The good midfield work of Frank Lampard, Steven Gerrard and Gareth Barry doesn't appear to transfer very well to the forwards, with Wayne Rooney receiving on average three times more passes than Jermain Defoe. This makes the English attack very predictable and easily stoppable by blocking Rooney, who is usually forced to give the ball back to Gerrard."
The German network appears even more balanced than the English one, with a higher number of passes, suggesting more circulation of the ball. "Particularly relevant are the passes between Philipp Lahm and Bastian Schweinsteiger and most of the German attacks are built up from the defenders. Mesut Oezil makes good work connecting both sides of the field on the attack, making the German offensive game very effective and hard to defend against. The key player in the German strategy remains Schweinsteiger, who was effectively blocked by the Spanish midfielders' characteristic fast circulation in their semi-final defeat," said Dr López Peña.

iPhone is "Eye-Phone" for Pediatric Eye Surgeons in India

Narayana Nethralaya Pilots Breakthrough Telemedicine on iPhone in Quest to End Blindness in Children

Narayana Nethralaya Postgraduate Institute of Ophthalmology, Bangalore has helped evolve a unique tele-medicine software which allows screening of rural and semi-urban infants for a potentially blinding condition called Retinopathy of Prematurity along with other common conditions including ocular cancers.

The Condition
Retinopathy of Prematurity is the leading cause of preventable infant blindness worldwide. In India, over 8% of 27 million births each year are at risk of this potentially blinding condition. Roughly if 100 ‘at-risk’ infants are screened, 15-20% may require treatment that can prevent blindness. This requires a fast and efficient system of screening infants especially in the peripheral rural areas where expertise is lacking”, said Dr Anand Vinekar, Project Co-Ordinator & Pediatric Retinal Surgeon, Narayana Nethralaya, Bangalore.

"ROP requires treatment after diagnosis within 48 to 72 hours to prevent blindness. The problem in India is that the country has about 15 to 20 doctors trained to diagnose and treat patients with ROP, and they are located in the cities," Vinekar added.

The Solution
Laboratory assistants take pictures of the retinas of prematurely born babies and transmit them via broadband to pediatric eye surgeons, who could be hundreds or thousands of miles away.

These surgeons, using iPhones, enlarge the images and using the iPhone's graphics capabilities determine whether the baby needs immediate help.

"We wanted a standard platform and the iPhone proved to be the best. With other (GSM) handsets you find that different models have different features. With a Nokia for instance, you have many models which do or do not have all the features we need. So it was easy to standardize on the iPhone. The iPhone's large screen, resolution, graphics capabilities and features offered the good picture quality doctors require, and security in the form of easy-to-publish Adobe software -- which also helps to upload patient records immediately and securely," Vinekar said.

In addition to the graphics processing capabilities that the chip industry has provided through the iPhone, it is chipping in with the software used in treating RoP. This comes from i2i Telesolutions, a startup launched by an ex-Texas Instruments India executive, Sham Banerji.

"The iPhone's pinch-and-drag capabilities, apart from its amazing resolution, are unrivaled in other phone models and the surgeons therefore decided that this is best-suited for this kind of application," Banerji said. 

In India alone, thousands of children go blind every year. These numbers could fall as a result of efforts by Vinekar and others like him, along with the help of the government.

Currently, Vinekar, with surgeons such as Anna Ills of Calgary, Canada, are joining with regional governments and non-governmental bodies to use the broadband and the iPhone to fight blindness in newborns everywhere in the world.

Real World Heroes



The man in this picture is 32 year-old Dr Shiva, an eye surgeon living in the state of Orissa in India. The woman is ophthalmologist Dr Lucy Mathen from the London-based charity Second Sight. The boys are 9 year-old Subala Suna and 12 year-old Ranjit Bariha. Both were blind and had their sight restored by cataract surgery.

Earlier this year, Lucy met Dr Shiva and discovered that: - He had single-handedly cured 6,000 blind people in the past year - He had offered all the surgery free of charge - He took no salary and sleeps on the floor of his office - He works from 4.30am till midnight most days. Why?

Because the state of Orissa has at least half a million people unnecessarily blind from cataract. And he can restore sight in just three minutes (perhaps five minutes when it comes to children like the two in this picture).

Shiva comes from a poor family himself. So he has dedicated his life as an ophthalmologist to eradicating blindness from his home state. With his surgical skills he could be earning a fortune in one of India’s wealthy cities (where 80 per cent of eye surgeons work in private practice).

Second Sight seeks out doctors like Dr Shiva who are actually curing the blind. Second Sight's own experienced volunteer surgeons also work alongside teams like Dr Shiva’s and cure the blind themselves.

Second Sight does not spend one penny of donated money on office costs. Second Sight is run by volunteers. So your donation goes straight to the hospital where the operation is carried out.

Fitness for Kids - Part I

Children often have a natural tendency to play hard. In the ensuing series, we will explore ways and means to direct your child's energy into a lifelong love of physical activity.

Benefits of being active
When kids are active, their bodies can do the things they want and need them to do. Why? Because regular exercise provides these benefits:

  • strong muscles and bones
  • weight control
  • better sleep
  • more likely to be academically motivated, alert, and successful
  • a better outlook on life
  • decreased risk of developing type 2 diabetes...

Getting your children off the couch
For many children, going to the playground, biking or simply playing in the backyard has given way to watching television, playing video games and spending hours online. But it's never too late to get your kids off the couch. Use these simple tips to give your kids a lifelong appreciation for activities that strengthen their bodies.

Set a good example
Cannot over emphasize this enough: if you want active kids, be active yourself. Go for a brisk walk, ride your bike or spend some time playing a sport. Kids ages 6 to 17 years old need at least an hour a day of such moderate activities. Three or more days a week should be more vigorous activities such as those that include running or jumping rope.

Invite your friends and family to play a sport or to join you on a walk. Talk about physical activity as an opportunity to take care of your body, rather than a punishment or a chore. Praise, reward and encourage activity.

A parent's active lifestyle is a powerful stimulus for a child. You are a role model for your children; set a good example by making physical activity a priority in your life.

Limit screen time
A surefire way to increase your children's activity levels is to limit the number of hours they're allowed to watch television each day. You might limit screen time — including television, video games and computer time.

Motivating kids to be active
Anyone who's seen kids on a playground knows that most are naturally physically active and love to move around. But what might not be apparent is that climbing to the top of a slide or swinging from the monkey bars can help lead kids to a lifetime of being active.

As they get older, it can be a challenge for kids to get enough daily activity. Reasons include increasing demands of school, a feeling among some kids that they aren't good at sports, a lack of active role models, and busy working families.

And even if kids have the time and the desire to be active, parents may not feel comfortable letting them freely roam the neighborhood as kids once did. So their opportunities might be limited.

Despite these barriers, parents can instill a love of activity and help kids fit it into their everyday routines. Doing so can establish healthy patterns that will last into adulthood.

What motivates kids?
So there's a lot to gain from regular physical activity, but how do you encourage kids to do it? Some of the keys are:

  • Giving kids plenty of opportunity to be active: Encourage playing with peers, make activity easy by providing equipment and taking them to playgrounds and other active spots.
  • Don't impose, be good spectators: Allow the child to discover activities that's fun for them. If you don't, the child may be bored or frustrated.
  • Keeping the focus on fun, not winning sports trophies: Kids are naturally competitive and like to win but they won't do something they don't enjoy.

When kids find an activity that's fun, they'll do it a lot, get better at it, feel accomplished, and want to do it even more.

Age-appropriate activities
The best way for kids to get physical activity is by incorporating physical activity into their daily routine. Toddlers to teens need at least 60 minutes on most (preferably all) days. This can include free play at home, active time at school, and participation in classes or organized sports.

Preschoolers: Preschoolers need play and exercise that helps them continue to develop important motor skills — kicking or throwing a ball, playing tag or follow the leader, hopping on one foot, riding a bike, freeze dancing, or running obstacle courses.

Although some sports may be open to kids as young as 4, organized and team sports are not recommended until they're a little older. Preschoolers can't understand complex rules and often lack the attention span, skills, and coordination needed to play sports. Instead of learning to play a sport, they should work on fundamental skills.

School-age: With school-age kids spending more time on sedentary pursuits like watching TV and playing computer games, the challenge for parents is to help them find physical activities they enjoy and feel successful doing. These can range from traditional sports like cricket, badminton, basketball, etc.. to biking, hiking, and other outdoor pursuits.

As kids learn basic skills and simple rules in the early school-age years, there might only be a few athletic standouts. As kids get older, differences in ability and personality become more apparent. Commitment and interest level often go along with ability, which is why it's important to find an activity that's right for your child. Schedules start getting busy during these years, but don't forget to set aside some time for free play.

Kids' fitness personalities
In addition to a child's age, it's important to consider his or her fitness personality. Personality traits, genetics, and athletic ability combine to influence kids' attitudes toward participation in sports and other physical activities, particularly as they get older.

Which of these three types best describes your child?

  • The nonathlete: This child may lack athletic ability, interest in physical activity, or both.
  • The casual athlete: This child is interested in being active but isn't a star player and is at risk of getting discouraged in a competitive athletic environment.
  • The athlete: This child has athletic ability, is committed to a sport or activity, and likely to ramp up practice time and intensity of competition.

If you understand the concepts of temperament and fitness types, you'll be better able to help your kids find the right activities and get enough exercise — and find enjoyment in physical activity. Some kids want to pursue excellence in a sport, while others may be perfectly happy and fit as casual participants.

The athlete, for instance, will want to be on the basketball team, while the casual athlete may just enjoy shooting hoops in the playground. The nonathlete is likely to need a parent's help and encouragement to get and stay physically active. That's why it's important to encourage kids to remain active even through they aren't top performers.

Whatever their fitness personality, all kids can be physically fit. A parent's positive attitude will help a child who's reluctant to exercise.

Be active yourself and support your kids' interests. If you start this early enough, they'll come to regard activity as a normal — and fun — part of your family's everyday routine.

15 Kooky Inventions

Ever had a weird idea for a product? Check out what passes muster with the U.S. Patent and Trademark Office.
Cheese-Filter Cigarette
Cheese-Filter Cigarette
Patent 3,234,948
Millions of people across the world like to smoke. Many also enjoy cheese. Why not combine the two in a cigarette filter made of cheese? That way, you can relax and nibble at the same time--with no toxins left behind! So efficient was this ventricular assault that Stuart Stebbings of De Pere, Wis., patented the idea in 1964.

Middle East Conflict Board Game
Middle East Conflict Board Game
Patent 5,108,112
Think Monopoly, except in place of Boardwalk and Indiana Avenue you have spots like "Oil Spill, Lose 1 Barrel" and "Peace Talks" and "Find Saddam, Win 3 Barrels." The game, created by Debra A. Gould of Palmer, Mass., in 1991 and patented in 1992, revolves around a not-so-imaginary war between Iraq, Saudi Arabia and the U.S. The object: Collect missiles and oil barrels. The winning player is the one with the most barrels when the game's last missile is fired. (No matter that real-life Saddam lost with no missiles and plenty of oil.)

Dust Cover for Dog
Dust Cover for Dog
Patent 3,150,641
Don't want your dog getting all dusty? Neither did Seroun Kesh of Detroit in 1964. Actually, Kesh's main goals with this full-body suit for dogs were to protect house furniture and allow owners to insert a hair dryer into the suit's end to quick-dry their mutts after their baths. Not a PetSmart bestseller, to say the least.

Method of Concealing Partial Baldness
Method of Concealing Partial Baldness
Patent 4,022,227
In short: a patent for a multi-directional comb-over, secured in 1975 by Frank Smith and Donald Smith. It reads: "A partially bald person without the financial means can not afford the luxury of such hair coverings. This person, therefore ... can attempt to use his own hair to cover the bald area, but generally most people do not have the ability to properly plan a hair style that will look good, and most attempts result in brushing the hair in one direction over the bald area." Only one question remains: How much money does Donald Trump owe these guys?

Grave Attachments (Periscope)
Grave Attachments (Periscope)
Patent 901,407
In 1908 inventor George Willems of Roanoke, Ill., had a swell idea: attaching periscopes to coffins so that, once buried, they could be peeked into to ensure that the entombed person was still dead. For whatever reason, this device hasn't caught on in the mortuary business. Must be hard to landscape all those scopes at the cemetery.

Apparatus for Facilitating the Birth of a Child by Centrifugal Force
Apparatus for Facilitating the Birth of a Child by Centrifugal Force
Patent No. 3,216,423
With this ostensibly pain-easing contraption, one more fit for a NASA training center than a hospital, the laboring mother is strapped in and spun around at 82 revolutions per minute, fast enough to force the infant out of the birth canal and into the world. Not to worry: There's an internal governor that keeps the machine from going too fast and a cotton-backed net that's mounted below the woman to catch a flying newborn. Four decades later, hospitals still haven't signed on.

Combination Pillow and Crash Helmet
Combination Pillow and Crash Helmet
Patent No. 3,538,508
This really, really good pillow aims to help passengers survive a plane crash. The thing splits in half, so you can stuff your head into the middle and brace for impact, snug with the knowledge that you're protected. The pillow/helmet even has a drawstring at each end so the wearer can cinch it down tight over his or her noggin. When standard turbulence turns into a steep nosedive, get your fluffy crash helmet out and strap 'er down. You'll be fine.

Coffee Having a Nicotine Composition Dissolved Therein
Coffee Having a Nicotine Composition Dissolved Therein
Patent No. 6,749,882
Inventor Stephen Fortune brings together two of man's greatest vices, er, inventions ever. You know those chief executives who love to talk about going to bed at 2 a.m. and getting up at 4 a.m. so they can bench-press 300 pounds, run six miles and practice their backhand saber jabs--all before inking that next $100 million deal? The patent doesn't claim to render sleep irrelevant, but you might require way less of it after your patented morning brew. Slurp it, strap on your pillow crash helmet and prepare for launch.

Thong-Type Garment With Wire-frame Construction
Thong-Type Garment With Wire-frame Construction
Patent No. 6,738,988
Edward T. Ruiter's and Jacqueline Dugas-Ruiter's patented thong underwear keeps your thong where it belongs and nowhere else. Never mind the obvious threat that all that wire might pose.

User Operated Amusement Apparatus for Kicking the User's Buttocks
User Operated Amusement Apparatus for Kicking the User's Buttocks
Patent No. 6,293,874
With this device, care of inventor Joe W. Armstrong, users crank a shaft via a two-handed lever, which in turn rotates a pinwheel affixed with four boots. The wheel spins behind the user, giving him a swift kick jab every quarter turn. Who doesn't want a sore behind to go along with his upper body workout?

Musical Instrument Adapted to Emit a Controlled Flame
Musical Instrument Adapted to Emit a Controlled Flame
Patent No. 4,247,283
For those looking to add a little flare to their trumpeting, simply outfit your instrument with cartridge of flammable gas connected to an ignition switch. So cool it's hot--not.

Fresh-Air Breathing Device and Method
Fresh-Air Breathing Device and Method
Patent No. 4,320,756
Inventor William O. Holmes came up with the idea in the early 1980s after rash of fires in high-rise hotels. Holmes' tube-shaped device plunges into a toilet bowl, past the water trap and into the air on the other side, which blows in from the sewage stack pipe. The idea isn't utterly ridiculous, the gist being that trapped users can suck stinky but non-toxic air from the toilet until the fire fighters arrive. Just remember to take a break from pulling air through a toilet long enough to scream for help.

Pneumatic Shoe Lacing Apparatus
Pneumatic Shoe Lacing Apparatus
Patent No. 5,205,055
Remember those Nike shoes that Michael J. Fox sports in Back to the Future II--the ones that, with a touch of a button on the shoe tongue, tightened up to a perfect fit, no messy lace tying or hopelessly un-hip Velcro? Aaron D. Harrell figured he'd make those a reality, if a tortuously complicated one: These high-tops require a gas canister on the back of the shoe to power a pneumatic piston in the shoe's sole. The piston turns a crank on the side of the shoe that draws close the straps across the top--no laces needed. Great Scott, Marty, that's ridiculous!

Bird Trap and Cat Feeder
Bird Trap and Cat Feeder
Patent No. 4,150,505
Leo O. Voelker apparently had a soft spot for lazy cats. His contraption, patented in 1979, catches birds, which fly into a little house with a false floor attached to a downspout, and dispenses them uninjured to a cage below, where famished felines move in for the kill. This guy would be a hit at an ornithologists' convention.

San Quentin State Prison On Yelp: 2 Stars, Horrible Food

Happens only in America !! California’s oldest prison, with the largest death row in the country, is being actively reviewed on Yelp. Maybe this shouldn’t be all that surprising since there is a museum that you can take a tour of (and they occasionally do private tours). But if you read over the reviews, a number of them are from people who have family inside or have been in themselves. Sure, they could be lying, but it’s still kind of humorous.

Here’s one reviewer — a supposed former short-term inmate — that gave it 2 stars:

"In 1989 when I was 17 I made the mistake of borrowing a strangers car without their permission & after many months of courtroom banter I was sentenced to the California Youth Authority.
The 4 days I spent here were miserable. We all arrive on the grey goose & are schackled and escorted to a main pen to be counted & dispersed.
This place is cold & damp and just like every prison movie -(the green mile) you have ever seen depiciting a shit hole prison.
Yeah they play baseball with local sF organizations and they have deathrow inmates but mostly its a minimum/medium security facility with a bunch of short timers.
It's kind of nostalgic because of its sorted history but...
This is not a place you wanna end up. Not all big bad & scary like the movies make it, but cold,damp and miserable with really shitty food.
AVOID AT ALL COST!"

Wonder what inmates might think and how many stars they would give to Arthur Road, Tihar...

Science Vindicates Afternoon Naps, Yet Again

We all know that sleeping is a good thing. It refreshes us. There have been lots of studies that an afternoon nap makes you more productive. The latest research finally gave me a sophisticated way to describe the afternoon powernap: “a biphasic sleep schedule”. Telling your boss that you are pursuing a biphasic sleep schedule to maximize afternoon productivity is sure to be met with a better response than just telling your boss that you’re taking a nap.

New research from the University of California, Berkeley, shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.

Conversely, the more hours we spend awake, the more sluggish our minds become, according to the findings. The results support previous data from the same research team that pulling an all-nighter – a common practice at college during midterms and finals –- decreases the ability to cram in new facts by nearly 40 percent, due to a shutdown of brain regions during sleep deprivation.

"Sleep not only rights the wrong of prolonged wakefulness but, at a neurocognitive level, it moves you beyond where you were before you took a nap," said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of these studies.

In the recent UC Berkeley sleep study, 39 healthy young adults were divided into two groups – nap and no-nap. At noon, all the participants were subjected to a rigorous learning task intended to tax the hippocampus, a region of the brain that helps store fact-based memories. Both groups performed at comparable levels.

At 2 p.m., the nap group took a 90-minute siesta while the no-nap group stayed awake. Later that day, at 6 p.m., participants performed a new round of learning exercises. Those who remained awake throughout the day became worse at learning. In contrast, those who napped did markedly better and actually improved in their capacity to learn.

These findings reinforce the researchers' hypothesis that sleep is needed to clear the brain's short-term memory storage and make room for new information, said Walker, who is presenting his preliminary findings on Sunday, Feb. 21, at the annual meeting of the American Association of the Advancement of Science (AAAS) in San Diego, Calif.

Since 2007, Walker and other sleep researchers have established that fact-based memories are temporarily stored in the hippocampus before being sent to the brain's prefrontal cortex, which may have more storage space.

"It's as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact e-mails, you're not going to receive any more mail. It's just going to bounce until you sleep and move it into another folder," Walker said.

In the latest study, Walker and his team have broken new ground in discovering that this memory- refreshing process occurs when nappers are engaged in a specific stage of sleep. Electroencephalogram tests, which measure electrical activity in the brain, indicated that this refreshing of memory capacity is related to Stage 2 non-REM sleep, which takes place between deep sleep (non-REM) and the dream state known as Rapid Eye Movement (REM). Previously, the purpose of this stage was unclear, but the new results offer evidence as to why humans spend at least half their sleeping hours in Stage 2, non-REM, Walker said.

"I can't imagine Mother Nature would have us spend 50 percent of the night going from one sleep stage to another for no reason," Walker said. "Sleep is sophisticated. It acts locally to give us what we need."

Walker and his team will go on to investigate whether the reduction of sleep experienced by people as they get older is related to the documented decrease in our ability to learn as we age. Finding that link may be helpful in understanding such neurodegenerative conditions as Alzheimer's disease, Walker said.

Now if you’ll excuse me, it's time for my biphasic sleep schedule …

Perfect Time Trial Means Building Entire Day Around One Hour

 (In view of the recent Mumbai cyclothon, I am posting this excerpt from Chris Carmichael, Lance Armstrong's coach for many years. It gives us critical insights into how top athletes prepare for maximizing performance.)

By CHRIS CARMICHAEL

Imagine building your entire day around one hour. One hour in which only a perfect performance will be considered successful.

The final test in Lance Armstrong's quest to win a seventh Tour de France comes in Saturday's Stage 20 individual time trial, and after 14 years as a professional cyclist, it comes down to one perfect hour.

An individual time trial can be the loneliest hour of a cyclist's life. While most cycling events involve a pack of riders, you're all by yourself during the individual time trial. There are no teammates to call on for help and no one to draft behind. There's a car following you, but the people in it can't give you food or water. It's just you against the clock, fastest man wins.

Lance Armstrong excels in this discipline. To be successful in what's referred to as ``the race of truth,'' you have to have the ability to produce a massive amount of power and hold that intensity for 60-80 minutes. To win Saturday, Lance will have to average about 30-31 mph for about 72-74 minutes. To put that in perspective, the average cyclist can sustain 30-31 mph for about three minutes.

In order to win an individual time trial in the Tour de France, Lance seeks perfection. It's not enough to be perfect on the bike; everything he does from the moment he wakes up has an impact on his performance.

The day starts at about 8:30 a.m. Riders don't need to wake up exceedingly early because the daily stages are scheduled so they finish around 5:00 p.m. The whole team eats breakfast together at about 9:00 a.m. The meal consists of whole grain cereals, dark breads, omelets, fruit, and often potatoes or rice. It is quite high in carbohydrates because the body depletes about 80 percent of its carbohydrate stores in the liver overnight. 

After breakfast, Lance and his teammates will go out on the road for a short spin. Lance will ride his time trial bike for about 25-30 miles to get comfortable on the bike and stretch his legs. He hasn't been on this very specific machine for more than two weeks, and it's good to get reacquainted with it in the morning before competing in the afternoon.

Once he gets back from his morning ride at about 10:00 a.m.-10:30 a.m., Lance will talk with the mechanics about the bike and possibly make some slight adjustments. He'll get a shower and probably a quick massage to keep his legs and back supple and loose, and then he'll relax until lunch.

Lance will eat his last substantial meal about two and a half hours before his start time. As the race leader, Lance will be the last rider to roll out of the start house, so his start time will be late, probably around 4:22 p.m. The meal will be mostly carbohydrates because that's the primary fuel he'll be using to power his high intensity effort. He'll eat a few cups of a light pasta dish; he won't want anything that will sit heavily in his stomach. He'll also eat some whole grain bread, fruit, and maybe some salad. 

There is a rule in cycling that the shorter an event, the longer the warmup. For long road stages, riders barely warm up at all. Lance warms up for about 50 minutes before long individual time trials, and he'll arrive at the race site about 90 minutes before his start time to get ready and start warming up.

While Lance changes clothes in the team bus, his time trial bike will be put on a stationary trainer outside. Some of his teammates will be there warming up for their own time trials, and the others will already be on the course. Lance's 50-minute warmup is not just a simple spin to loosen up. To win a time trial, you have to be ready to ride at maximum speed from the moment you leave the start house. You have to prepare your body, otherwise the shock of going from rest to maximum effort will significantly harm your performance.

Lance's warmup is designed to wake a sleeping giant. He has to gradually activate his aerobic engine, and then increase intensity to progressively activate the energy systems that power successively harder efforts. Lance goes hard in his warmup, and actually goes above the effort level he reaches during competition. He needs to kick-start the mechanisms that control the production of energy and metabolic byproducts when exercising at very high intensities.

About 10 minutes before his start time, Lance wraps up his warmup, eats a PowerGel and tucks another under the leg of his skinsuit. His bike is removed from the stationary trainer, checked over by the mechanic, and Lance heads for the start house.

Once Lance looks down the ramp to the road ahead, all of the hours since he woke up melt away. He sits still on his bike, both feet secured onto his pedals while someone holds him upright by the back of his seat. The starter finally begins the countdown. His fingers count down the final five seconds to Lance's start time, and then his hand flattens and extends out over the ramp. It's time to go.

For the next hour and change, Lance will ride as hard and fast as his body and physics will allow. Though he'll burn more than 1500 calories during the effort and sweat out about two liters of fluid, he'll only consume one 100-calorie PowerGel and one 500-millileter bottle of fluid. There's no time for more food and nowhere to carry more fluid.

Moreover, there's no room for error. There can be no stiff back from a poor night's sleep, nor an empty or upset stomach from a bad or incorrectly-scheduled meal, or mechanical problems with the bike or insufficient power from an inadequate warmup. Perfect rides come from perfect preparation, and there's no one who has mastered the art and science of preparation the way Lance Armstrong has.

Best Science Picture of 2009











"Save Our Earth, Let’s Go Green"



Fibers cradle a planet-like ball in an award-winning image meant to convey that Earth's future is in our collective hands.
Harvard University's Sung Hoon Kang submerged tiny plastic fibers—each only 1/500 as big as a human hair—in an evaporating liquid, where they spontaneously and cooperatively supported the small green ball.
"Using the image, I tried to describe cooperative efforts across the world to save our Earth by going green," Hoon said.
The shot was selected as best photograph in the 2009 International Science and Engineering Visualization Challenge. The annual contest, sponsored by the National Science Foundation and the journal Science, award outstanding artistic efforts to visualize complex scientific concepts.

New Clue Why Autistic People Don't Want Hugs

Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch -- even from their parents?

New research has found in fragile X syndrome there is delayed development of the sensory cortex, the part of the brain that responds to touch, according to a study from Northwestern University Feinberg School of Medicine. This delay may trigger a domino effect and cause further problems with the correct wiring of the brain. Understanding how and when the function of the brain is affected in fragile X offers a target for a therapy to fix the incorrect development.

"There is a 'critical period' during development, when the brain is very plastic and is changing rapidly," said Anis Contractor, assistant professor of physiology at Feinberg and the lead investigator of the study. "All the elements of this rapid development have to be coordinated so that the brain becomes wired correctly and therefore functions properly."

The study will be published in the Feb. 11 issue of the journal Neuron.

Working with a mouse model of fragile X, Contractor found the development of synapses, the sites where neurons communicate with each other, was delayed in the sensory cortex.

"The critical period may provide a window during which therapeutic intervention can correct synaptic development and reverse some of the symptoms of the disease," Contractor said.

People with this syndrome have debilitating sensory as well as cognitive problems. "They have tactile defensiveness," Contractor explained. "They don't look in people's eyes, they won't hug their parents, and they are hypersensitive to touch and sound. All of this causes anxiety for family and friends as well as for the fragile X patients themselves. Now we have the first understanding of what goes wrong in the brain."

The sensory overload in people with fragile X results in social withdrawal, hyperarousal and anxiety. It shows up in early infancy and progressively worsens throughout childhood.

Fragile X syndrome is caused by a gene mutation in the X chromosome that interferes in the production of a protein called fragile X mental retardation protein (FMRP). That protein directs the formation of other proteins that build synapses in the brain. People with fragile X are missing FMRP. It's as if the foreman is missing on the brain's key construction site. Fragile X is so named because the X chromosome appears broken or kinked.

Boys are more severely affected by fragile X because they have only one X chromosome. Girls, who have two X chromosomes, are less affected by the defect.

Contractor and colleagues discovered the sensory cortex was late to mature by recording the electrical signals flowing through the animals' synapses. This provided a snapshot of when and how this part of the brain was developing. The ability of the brain to correctly process incoming information is based on the correct development of these synapses, he noted.

This is one of the first studies to show how synapses in this region are altered. "It starts to build a framework for how this part of the cortex actually develops," Contractor said. "Our next step is to work out what is going wrong. How does elimination of this gene FMR1 disrupt the normal developmental processes?"

The research was supported by the FRAXA Research Foundation and Autism Speaks.
