Sinclair and several other prominent gerontologists are presently seeking human therapies based on the long-standing observation that lifelong restriction of caloric intake considerably extends both the healthy and total life span of nearly all species in which it has been tried, including rodents and dogs. Drugs that…
Here are some examples of the principles that teachers can use to expand concepts presented in formal course material. These principles don't have to be taught in the context of any particular class. It's an empirical question. This is a comment that ought to terminate many more conversations than it does. For many of…
Why do some children find Math hard to learn? I suspect that this is often caused by starting with the practice and drill of a bunch of skills called Arithmetic—and instead of promoting inventiveness, we focus on preventing mistakes. I suspect that this negative emphasis leads many children not only to dislike…
A new class of 6-year-old children will soon begin to share similar ways to think and behave. Then, next year, when they are 7 years old, most of those pupils will still remain in that group—and thus will tend to perpetuate those same patterns of activity. The next year, they will be 8-year-olds, but will continue to…
Humans, of course, were not created in a state of Original Reason. We descended from apes, spent hundreds of millennia in small bands, and evolved our cognitive processes in the service of hunting, gathering, and socializing. Only gradually, with the appearance of literacy, cities, and long-distance travel and…
At least since Dr. Spock, child-care gurus have increasingly advised against spanking.175 Today every pediatric and psychological association opposes the practice, though not always in language as clear as the title of a recent article by Murray Straus: “Children Should Never, Ever, Be Spanked No Matter What the…
Luard calls the first of his ages, which ran from 1400 to 1559, the Age of Dynasties. In this epoch, royal “houses,” or extended coalitions based on kinship, vied for control of European turfs. A little biology shows why the idea of basing leadership on inheritance is a recipe for endless wars of succession. Rulers…
This is the first systematic review and meta-analysis to summarize data available on the effects of mindfulness-based trainings for children and youths in a school setting. Twenty-four studies were located that report a significant medium effect size of g = 0.40 across all controlled studies and domains. Remarkably…
Take the word ghost, for example. Always having seen it speld in this way, we hav come to associate the feelings arousd by the idea ghost with its accustomd form of visual representation. To meet the word in our reading instantly and instinctivly excites those feelings in our minds. To meet the same word speld gost…
Forty-five percent of people who go to college, four year colleges, don't get a bachelors degree within six years. Those people often have met with disappointment and their investment isn't particularly good, necessarily. Another group of people graduate from college and then have trouble getting jobs and end up…
Enlightened believe in science, observation, and understanding of natural phenomenon. The word Solstice reflects that on this one day, the sun stands still How did the ancients explain this? With Fear or Celebration? They turned to astronomy and the observation of the heavenly bodies that dance in the depths of space…
Even when writers profess to know nothing about the inner man, they often make the profession in a way which suggests that they really know plenty When D. H. Lawrence says (in his essay on Benjamin Franklin) "The soul of man is a dark forest," he says it with a kind of knowing Satanic smirk, so that the profession of…
A new study appearing Aug. 1 in the journal Current Anthropology finds that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming. “The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at…
I’m not the first person to notice that reality is broken compared with games, especially when it comes to giving us good, hard work. In fact, the science of happiness was first born thirty-five years ago, when an American psychologist by the name of Mihály Csíkszentmihályi observed the very same thing. In 1975…
As a golfer, you have a clear goal: to get a ball in a series of very small holes, with fewer tries than anyone else. If you weren’t playing a game, you’d achieve this goal the most efficient way possible: you’d walk right up to each hole and drop the ball in with your hand. What makes golf a game is that you…
Organic chemistry just now is enough to drive one mad. It gives one the impression of a primeval, tropical forest full of the most remarkable things, may well dread to enter. may well dread to enter.
Explanation: Sophisticated and apt theories and illustrations, which provide knowledgeable and justified accounts of events, actions, and ideas. Why is that so? What explains such events? What accounts for such action? How can we prove it? To what action is this connected? How does this work? Interpretation: The act…
As nearly as I can see, the only secret in popularising science (or anything else) is remembering what thinking went on in your head when you first really understood whatever it is you're now explaining: especially (1) what misunderstandings needed to be cleared away, (2) what metaphors and analogies proved helpful…
In a series of experiments, the researchers found that pressing financial concerns had an immediate impact on the ability of low-income individuals to perform on common cognitive and logic tests. On average, a person preoccupied with money problems exhibited a drop in cognitive function similar to a 13-point dip in…
The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but…
