memory memorization eye movement

  • If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.
  • It may be that this quick activity helps facilitate interaction between the brain hemispheres.
  • any activity that encourages communication between the hemispheres is likely to increase recall.
  • ...6 more annotations...
  • people who have poorer interactions between the hemispheres should benefit more than others. Who has less interactions between hemispheres? People who are strongly right-handed.
  • Strongly right-handed students remembered significantly more words if they moved their eyes compared to keeping their eyes still. Non-strongly-right-handed students (including left-handers) remembered the same number of words regardless of whether they moved their eyes before the test.
  • strongly right-handed students had significantly fewer false alarms after they moved their eyes back and forth. But for non-strongly-right-handed people, the reverse occurred; moving their eyes caused them to falsely remember more words. So overall, while the eye-saccade exercise helped right-handers, for lefties and for those who didn't have a strongly dominant hand, the exercise actually harmed their performance.
  • You might think that only side-to-side movement would improve performance, but Lyle's team found that moving your eyes up and down caused the same effect.
  • researchers say that other studies have shown that any eye movements increase bilateral activity in the frontal eye field, so it's still possible that hemispheric connectivity can explain the improved performance after eye movements.
  • So why doesn't the exercise work the same way for left-handers? Left handers (and ambidextrous individuals) already have a high level of hemispheric connectivity. Lyle's team speculates that there might be such a thing as too much connectivity, which results in a decrease in performance.

    Several studies have confirmed this bizarre proposition: If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.

  • If you give girls and boys language tasks, most girls will process the information in the same way (in a specialized language area)
  • help them with word storage and retrieval
  • But for boys, sensitivity to the modality of how words are presented means that an extra steps need to be taken to match words that are picked up by listening and words that are read on the printed page. No wonder dyslexia is much more common in boys - the separate system means that the sight and sound of words are learned as distinct processes.
  • ...4 more annotations...
  • As a result, verbal competence may be strong in one domain (oral speech for instance), but be weak in another (reading).
  • because boys require two areas and a matching of visual-auditory inputs, impairment in one system may cause the whole language coordination process to fail.
  • The visual-auditory gap may also be why some boys may need to read word-for-word outloud or to themselves (i.e. not silently read) in order to fully comprehend or remember the story.
  • Some careful consideration needs to made of instructional implications for boys given some of these new discoveries. Learning by listening and learning by reading are not synonymous; route-congruent factors(listening - oral presentation, reading - written response) may need to be considered when a learning gap or frank underachievement is seen, and an insistence on the availability of auditory-visual supports (reading along with books-on-tape, detailed handouts for lecture courses) should be a requirement of every classroom.

    It's good for your life and health to be optimist.

    It' s a slightly different perspective that I' m enjoying at this time but I appreciate it may only be true for some-I' ve just begun to understand what "faith" means tho I' m not religious-still! (I feel some empathy now as to why people are) I feel much more inclined to just sit still and connect inside with the Source of me-any meditation or spiritual practice can lead me there or creativity,music too,nature! But to deliberately connect to the part of us all that is connected and knows/is All. From that place I' ve understood that theres noone to be, nowhere to go, nothing to do as we are all there already as we are all IT! So of course daily I forget this but this insight has gifted me much more optimism as I can assume that whatever I really ask for/intend/desire is already in the big melting pot that we can Life/God. That is ' faith' Ive realised now- to ask and know intimately that it' s already a given and to STOP Worrying and completely ignore the naysayers etc. It' s really trusting that I' m connected to it all and I am not separate. I' m beginning to observe quite distinctly the thoughts that separate me from what I want/intend. Particularly in relation to my fellow beings! But then I turn to the place that is connected and I feel so good! and just thinking of the situation from that place and holding that good feeling in relation and giving it over (the problem) really helps! I know several spiritual teachers have said "give it over to me". I' m starting to understand it really is that simple. Trying hard and worrying just create such muck and mire! This may be part of the surrender letting go and letting God that others speak of also? I reckon it would be interesting to see where how people get there faith/trust in life that creates the underlying optimism. What gives that to them? I remember as a child I had it naturally I often got what I asked for and intended and there was an abundance of flow and optimism. No resistance. Fear and doubt come later

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.”
