neuroscience brain aging adult learning tots research training

  • One explanation for how this occurs comes from Deborah M. Burke, a professor of psychology at Pomona College in California. Dr. Burke has done research on “tots,” those tip-of-the-tongue times when you know something but can’t quite call it to mind. Dr. Burke’s research shows that such incidents increase in part because neural connections, which receive, process and transmit information, can weaken with disuse or age.
  • But she also finds that if you are primed with sounds that are close to those you’re trying to remember — say someone talks about cherry pits as you try to recall Brad Pitt’s name — suddenly the lost name will pop into mind. The similarity in sounds can jump-start a limp brain connection. (It also sometimes works to silently run through the alphabet until landing on the first letter of the wayward word.)
  • Recently, researchers have found even more positive news. The brain, as it traverses middle age, gets better at recognizing the central idea, the big picture. If kept in good shape, the brain can continue to build pathways that help its owner recognize patterns and, as a consequence, see significance and even solutions much faster than a young person can.

  • The trick is finding ways to keep brain connections in good condition and to grow more of them.
  • Educators say that, for adults, one way to nudge neurons in the right direction is to challenge the very assumptions they have worked so hard to accumulate while young. With a brain already full of well-connected pathways, adult learners should “jiggle their synapses a bit” by confronting thoughts that are contrary to their own, says Dr. Taylor, who is 66.
  • Teaching new facts should not be the focus of adult education, she says. Instead, continued brain development and a richer form of learning may require that you “bump up against people and ideas” that are different. In a history class, that might mean reading multiple viewpoints, and then prying open brain networks by reflecting on how what was learned has changed your view of the world.
  • Such stretching is exactly what scientists say best keeps a brain in tune: get out of the comfort zone to push and nourish your brain. Do anything from learning a foreign language to taking a different route to work.
  • “As adults we have these well-trodden paths in our synapses,” Dr. Taylor says. “We have to crack the cognitive egg and scramble it up. And if you learn something this way, when you think of it again you’ll have an overlay of complexity you didn’t have before — and help your brain keep developing as well.”

brain reading dorsal route Dehaene research E-books

  • Although scientists had previously assumed that the dorsal route ceased to be active once we learned how to read, Deheane's research demonstrates that even literate adults still rely, in some situations, on the same patterns of brain activity as a first-grader, carefully sounding out the syllables.
  • This research suggests that the act of reading observes a gradient of fluency. Familiar sentences printed in Helvetica activate the ventral route, while difficult prose filled with jargon and fancy words and printed in an illegible font require us to use the slow dorsal route.
  • The larger point is that most complaints about E-Books and Kindle apps boil down to a single problem: they don't feel as "effortless" or "automatic" as old-fashioned books. But here's the wonderful thing about the human brain: give it a little time and practice and it can make just about anything automatic.

brain visual training automobile drivers DriveSharp merzenich

  • Today, Posit Science announced the release of a new computer-based visual training tool, DriveSharp, specifically designed to improve the performance abilities of adult automobile drivers to a degree that can be expected to very substantially impact their driving safety.
  • Again, with a few hours of intensive training, a youthful MOT performance level can be achieved for most individuals. The result: A still FURTHER increase of driving safety.
  • In our fast-moving world, losing control of one’s peripheral vision is a main cause of driving accidents.
  • ...11 more annotations...
  • Ball and Roenker demonstrated that these losses are substantially reversible, through appropriate, intensive training, in almost all older drivers. UFOVs can be re-expanded to relatively youthful ability levels through only a few hours of exercise. The result: About 50% fewer driving accidents in the over-65 population.
  • Moreover, once your UFOV is opened up again, you use it!
  • You can use DriveSharp repeatedly, over the rest of your days, to keep yourself in fine driving fettle!
  • The second training program that is included in DriveSharp is designed to improve your ability to keep track of more than one thing happening at the same time. This fundamental visual skill — called “multiple object tracking” (MOT) — also dramatically declines as you get older.
  • As you get older, you progressively lose the ability to accurately detect and respond to visual events in your far visual periphery.
  • If you’ve reached your 50th birthday, DriveSharp training is especially important for upgrading and sustaining your driving competence. It’s all about maintaining your performance abilities in driving as in all other ways at the highest possible level, throughout the second half of life.
  • few other benefits demonstrated by published studies originating with the Ball/Roenker team (including University of South Florida scientist Sherri Willis and a University of Iowa scientist, Fred Wolinsky).
  • 1) You’re healthier after DriveSharp training! Five years after training, Physical indices of Quality of Life are more than 30% higher — maybe because you get out more.
  • Trainees are much more likely to have retained your driver’s license — and to have sustained their personal independence.
  • After DriveSharp, you are a more confident driver, as expressed by gains in the number of times you drive each week, by an increase in average driving distances, and by your driving more often at night, or in the rain or snow.
  • Try DriveSharp now: If you are a member of one of the participating AAA clubs, please visit your AAA club’s website for more information and a special offer on DriveSharp. If not, please visit www.DriveSharp.com or call (866)599-6463 to learn more.
