Risk-taking seniors making daring mental leaps? That's not the stereotype. Indeed, until quite recently most researchers believed the human brain followed a fairly predictable developmental arc. It started out protean, gained shape and intellectual muscle as it matured, and reached its peak of power and nimbleness by age 40. After that, the brain began a slow decline, clouding up little by little until, by age 60 or 70, it had lost much of its ability to retain new information and was fumbling with what it had. But that was all right because late-life crankiness had by then...
...Stone and Harvard, a typically strong third-period team this season, in their attempt to avenge a home loss to UNH over a month ago. Before Wednesday, the Crimson had outscored its opponents 32-10 in the final frame. The exhaustive effort on the penalty kill and the mental lapses on defense, however, ultimately took their toll as UNH asserted itself and validated its new No. 1 spot. “I thought we did a pretty good job of defending the big sheet, which is difficult to do,” Stone said. “I was just...
What sort of toll is all this disruption and mental channel switching taking on our ability to think clearly, work effectively and function as healthy human beings? Do the devices that make it possible to do so many things at once truly raise our productivity or merely help us spin our wheels faster? Over the past five years, psychologists, efficiency experts and information-technology researchers have begun to explore those questions in detail. They have begun to calculate the pluses, the minuses and the economic costs of the interrupted life--in dollars, productivity and dysfunction. More important, they're exploring...
...placebo-controlled laboratory experiments say exactly the same thing. Just last month Austrian scientists reported on a study showing that the equivalent of two cups of coffee boosts short-term memory significantly. And that's just the latest in a long line of tests proving that caffeine can enhance mental performance...
...Military Nutrition Division of the U.S. Army Research Institute of Environmental Medicine in Natick, Mass., "I use the word intelligence as an inherent trait, something permanently part of your makeup." Caffeine can't change that, Lieberman says. But what it can do, he says, is heighten your mental performance. If you're well rested, it tends to improve rudimentary brain functions, like keeping your attention focused on boring, repetitive tasks for long periods. "It also tends to improve mood," he says, "and makes people feel more energetic, generally better overall." Observes Dr. Peter Martin, professor of psychiatry and pharmacology...
