All children, if given the chance, will play, preferably with other children. The games they play
are often creative, rough and tumble, and of course―fun. Some consequences are obvious:

·         Fun is a positively reinforcing emotion. It makes kids happy.
·         Play encourages exploration with fewer constraining boundaries than the drone of regular life.
·         Play is an effective way to socialize and make friends.
·         Play stimulates initiative and engagement, rather than passively observing what others do.

But there is another less obvious reason, one that is biological. In a review in the American Journal of Play (yes, there really is a scholarly journal on play), evidence is provided from controlled studies in rats and some primates. These studies show that when young animals are encouraged to play they develop improved social competence, cognition, and emotional regulation later in life. Play experience also makes them more adaptable to unexpected situations.

It is true that play is not a developmental feature in all species. The capacity (and need) for play is most evident in higher mammals with developed neocortex and that live in complex social environments. Play fighting is adaptive in predator species, like bears and lions that depend on aggression for survival as adults. In all species that exhibit juvenile play, play is a developmental tool that promotes the neocortical executive control regions to control other neural systems.

Play fighting is especially interesting because the juveniles must construct and obey certain rules. They intuitively recognize that they must not bite too hard, for example, and must give the opponent at chance to win sometimes or at least hold their own in the contest. The juveniles are clearly learning self-control, which will serve them well as adult. This reminds me of the touch football games that kids play.

Species that most obviously exhibit juvenile play are humans, dogs, cats, and ravens. In species where adults play, play can have immediate functions such as defusing social tensions and dominance relationships. Rats are an interesting case. They engage in juvenile play much more than other rodent species. Adult rats seem to exhibit novel mental capabilities, especially those involving social interactions that are not so prominent in other rodents.

When members of a play-oriented species are denied access to juvenile play, they can become dysfunctional adults. For example, rats raised in social isolation show physical and chemical deficiencies in their brains and they have behavioral abnormalities linked to impaired executive control function. They show excessive anxiety to stressful or fear-inducing situations. They over-react to benign social interactions. They are less able to coordinate movements with a partner, both in sexual and non-sexual contexts. They are less able to solve mental tasks. Similar problem are seen in monkeys deprived of juvenile play. Being raised by a surrogate mother is emotionally and intellectually devastating, but less so if the surrogate is robot-like and can interact in play-like behavior with the infant.

Juvenile play sculpts the brain to be more adaptable later in life. In modern human society, juvenile play is often obstructed by such externals as over-scheduling, too much adult supervision, and too many restrictions. The restrictions are often for reasons of safety, which is understandable in today's world. When I was a child, we had a lot more freedom to play, and in safety. It was not unusual in the summer time for a kid to leave home after breakfast and not return until supper, going alone to a park or neighbor kid's house to play unsupervised as we wished. Sadly, that is too much freedom these days. In this respect, the "good old days" really were the "good old days."

If we learn anything about educational policy, we should learn that what we have tried over the last couple of decades to improve student achievement doesn’t work very well. I won’t bore you with all the statistics showing that academic ability of U.S. students lags that of most other developed countries and our ranking is not improving. I would like to explore one reason for lack of progress besides faulty federal policy. And that reason is research funding. We don’t know enough about how brains learn and remember, nor how to apply what we do know to educational policy.

The recently announced winners of the Nobel Prize included nine from the U.S. In a recent joint interview by leaders of the American Association of Science, the winners spent little time discussing their research achievements, preferring to expound on some serious concerns about how research is now funded in the U.S.

Of course, some of these concerns could be considered whining. Like much of the general public, the scientific community has become dependent on government. When federal funds don’t grow at high rates, scientists can be cry-babies too. Nobody seems to care much about the growing federal debt and a very real threat of looming financial disaster in this country. Interest groups, including those in science, think if we have to cut funding, it should come out of somebody else’s piece of the pie. As a result, nothing much gets cut anywhere.

But there are legitimate issues about science policy and how federal money is allocated for research. The U.S. leads the world in Nobel Prizes by about 3 to 1. Actually, this understates our prowess. Young scientists from all over the world come here to learn world-class science, but we make most of them go back home to become science superstars in their own country. At the same time, we have little stomach for deporting uneducated illegal aliens. It’s hard to think of a more stupid immigration policy.

Randy Schekman, physiology winner, said that many of our best young foreign scientists are "returning to their countries because those countries, unlike ours, see the promise of investment in basic science. It's actual damage that's occurring right now." Several of the other laureates concurred.

The future of U.S. science may well be in jeopardy. The new Nobelists point out that the buying power of National Institute of Health funding has shrunk by 28% over the last seven or eight years. Moreover, government needs to re-think how that money is distributed. For example:

·         Michael Levitt, who won the award for chemistry, said "A huge change in the last 30 years has been that people under 40 get almost no money, and people over 65 get lots of money. Everyone here would agree that we made our discoveries when we were under 40."

·         James Rothman, winner in physiology, blamed big-science mentality where too much money as being “allocated into pre-determined projects is heading toward bureaucrat-driven science."

I fought the grant wars for years and finally gave up. I got too few grants for all the time I wasted writing proposals. Several of the Nobelists commented on how much time scientists waste writing proposals that don’t get funded.

Another part of the problem, apparently not mentioned in the interview, is that too much money is soaked up by too few grants. Universities have negotiated enormous overhead fees, sometimes exceeding 100% of the grant, and that is money that mostly goes into the institutions’ general fund, not the funded project. Also, too much grant money goes to salary support for the scientists. It used to be that universities were committed to supporting their scientists. Now, universities expect their scientists to hustle money for the university. As a result, too much grant money gets consumed by projects that are scientifically sexy and will sell, not necessarily for the most promising science. An associated problem is that government spends way too much grant money pursuing scientific fads. Far too many areas in science have no chance of getting competitive funding simply because they are currently unfashionable.
