兵者，詭道也。故能而示之不能，用而示之不用，近而示之遠，遠而示之近。利而誘之，亂而取之，實而備之，強而避之，怒而撓之，卑而驕之，佚而勞之，親而離之。攻其無備，出其不意，此兵家之勝，不可先傳也。 All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away;when far away, we must make…
As the epochs passed, the two species molded one another to form a well-integrated union. The little arachnoid, no bigger than a chimpanzee, rode in a snug hollow behind the great "fish's" skull, his back being stream-lined with the contours of the larger creature. The tentacles of the ichthyoid were specialized for…

Healthy aging can lead to impairments in learning that affect many laboratory and real-life tasks. These tasks often involve the acquisition of dynamic contingencies, which requires adjusting the rate of learning to environmental statistics. For example, learning rate should increase when expectations are uncertain…

In children up to eight or nine years old, the dopamine-modulating reward center in the nucleus accumbens reacts strongly to positive feedback (activating the prefrontal cortex) and minimally to negative feedback. In older children, increased activation still occurs in the PFC when dopamine is released in response to…
We all know that exercise is important for a strong and healthy body. Less appreciated is that exercise seems also to be important for a strong and healthy mind, boosting memory and learning, while possibly delaying age-related cognitive decline [1]. How is this so? Researchers have assembled a growing body of…
Brand: I was looking at your 1988 book, Infinite in All Directions, and remembering what it was that excited me about it. Ten years ago, most people I knew were in the depths of a kind of bad mood, harboring a pessimistic feeling that things were going to keep getting worse for the rest of their lives. But your book…
If one looks at the history of knowledge, it is plain that at the beginning men tried to know because they had to do so in order to live. In the absence of that organic guidance given by their structure to other animals, man had to find out what he was about, and he could find out only by studying the environment…
How does it feel to be in "the flow"? Completely involved, focused, concentrating - with this either due to innate curiosity or as the result of training Sense of ecstasy - of being outside everyday reality Great inner clarity - knowing what needs to be done and how well it is going Knowing the activity is doable…
So let's think. What is it like to be a baby? What's it like to be a child? Our emotions go up and down. We might be in a sort of happy, sort of ecstatic state one minute, giggling, finding everything funny and silly - similar things happen on psychedelics - and then the next minute there's a sudden shift and we're…
Mary and John are the unfortunate (fictional) protagonists of The Crack in the Picture Window, published in 1957 by John Keats, a journalist at the now defunct Washington Daily News. A lacerating (and very funny) indictment of postwar suburbs as "fresh-air slums," Keats’s polemic sold millions of copies in paperback…
Sustained engagement in mentally challenging activities has been shown to improve memory in older adults. We hypothesized that a busy schedule would be a proxy for an engaged lifestyle and would facilitate cognition. Here, we examined the relationship between busyness and cognition in adults aged 50–89. Participants…
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…
In 2008, the National Institute of Literacy issued its report, Developing Early Literacy: Report of the National Early Literacy Panel, and, among its many findings, stated that the foundational reading and writing skills that develop from birth to age five have a clear and consistently strong relationship with later…
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…
