    • Katie Raborn
       
      They have created mathematical models
  • “The model can look, like infants, at a world that includes dynamic, stimulating events that influence where it looks. We contend (the model) provides a critical link to studying how social partners influence how infants distribute their looks, learn, and develop,”
    • Katie Raborn
       
      This is how the model works.

  • The model examines the looking-learning behavior of infants as young as 6 weeks through one year of age, through 4,800 simulations at various points in development involving multiple stimuli and tasks. As would be expected, most infants introduced to new objects tend to look at them to gather information about them; once they do, they are “biased” to look away from them in search of something new
  • an infant will linger on something that’s being shown to it for the first time as it learns about it, and that the “total looking time” will decrease as the infant becomes more familiar with it.
    • Katie Raborn
       
      An infant will look at something until he/she is familiar with it.
  • infants who don’t spend a sufficient amount of time studying a new object—in effect, failing to learn about it and to catalog that knowledge into memory—don’t catch on as well, which can affect their learning later on.
    • Katie Raborn
       
      Infants that don't spend enough time studying a new object, later on will affect their learning later on in their lifetime.

  • To examine why infants need to dwell on objects to learn about them, the researchers created two different models. One model learned in a "responsive" world: Every time the model looked away from a new object, the object was jiggled to get the model to look at it again. The other model learned in a "nonresponsive" world: when this model looked at a new object, objects elsewhere were jiggled to distract it. The results showed that the responsive models“learned about new objects more robustly, more quickly, and are better learners in the end,
  • infants can familiarize themselves with new objects, and store them into memory well enough that when shown them again, they quickly recognized them
  • “if that’s the case, we can manipulate and change what the brain is doing” to aid infants born prematurely or who have special needs, Perone adds.

Newborn infants learn while asleep; Study may lead to later disability tests - 0 views

  • "We found a basic form of learning in sleeping newborns, a type of learning that may not be seen in sleeping adults
    • Katie Raborn
       
      Newborns could learn while sleeping. How do they learn while sleeping? How do they figure that out? How come sleeping adults can't do that, since adults are more developed?

  • ested the learning abilities of sleeping newborns by repeating tones that were followed by a gentle puff of air to the eyelids.
    • Katie Raborn
       
      They tested the newborns by the repeating tones. Could they test other things to figure out how newborns learn while sleeping? How do they know if they aren't just dreaming instead of learning?
  • After about 20 minutes, 24 of the 26 babies squeezed their eyelids together when the tone was sounded without the puff of air.
  • The brain waves of the 24 infants were found to change, providing a neural measurement of memory updating.
    • Katie Raborn
       
      So brainwaves detect memory updating.
  • While past studies find this type of learning can occur in infants who are awake, this is the first study to document it in their most frequent state, while they are asleep
    • Katie Raborn
       
      Infants learn while their awake but can also be found while they are asleep.
  • Learned eyelid movement reflects the normal functioning of the circuitry in the cerebellum, a neural structure at the base of the brain. This study's method potentially offers a unique non-invasive tool for early identification of infants with atypical cerebellar structure, who are potentially at risk for a range of developmental disorders, including autism and dyslexia, she said.
  • Newborn infants' sleep patterns are quite different than those of older children or adults in that they show more active sleep where heart and breathing rates are very changeable," she said. "It may be this sleep state is more amenable to experiencing the world in a way that facilitates learning."
  • Another factor is that infants' brains have greater neural plasticity, which is the ability for the neural connections to be changed

What we can learn from procrastination : The New Yorker - 0 views

  • The philosopher Mark Kingwell puts it in existential terms: “Procrastination most often arises from a sense that there is too much to do, and hence no single aspect of the to-do worth doing
  • Underneath this rather antic form of action-as-inaction is the much more unsettling question whether anything is worth doing at all.”
  • The procrastinator’s challenge, and perhaps the philosopher’s, too, is to figure out which is which.
  •  
    Interesting. Long, never gets to an end point...sounds like something I would write. Many various sources, from economists to social scientists to philosophers. I found it interesting that academics and scholars were more prone to it, and that in the adult world there are many prime examples of procrastinations directly marring their gain (i.e., tax returns).

New Studies Reveal Infants' World of Vision - 0 views

  • eye-tracking technology has been around for years, it is now small enough to be used to examine how toddlers view their environment.

  • Finn, an 8.5-month-old toddler, was among the participants in this project. She was being coaxed to wear the eye-tracking headgear, which consists of two cameras - one that's looking out on the scene to get the baby's perspective, and another that's looking at the eye to track the movement of the pupil. A computer analyzed both camera views to determine exactly where Finn was looking.

      They tested an 8.5 month-old toddler, named Finn with the new eye tracking gear. The gear weighs only 45.4 grams.

  • infants would be looking at their mothers constantly because that was common knowledge within [the field of] social cognition with infants." But in a room full of toys scattered everywhere and obstacles to climb on and crawl on, the infants only looked toward their mothers about half the time.  And even if they did look at their mothers, they looked at their mothers' faces only about 15 percent of the time.
  • toddlers almost always look directly at the object when reaching for it.
  • Toddlers are able to use information from their peripheral vision and still walk very well.
  • Another interesting finding was that while infants look directly at an obstacle before walking onto or over it, 75 percent of the time they don't always have to.
    • Katie Raborn
       
      The toddlers didn't have to look at the obstacle all the time. they were able to use information for their peripheral vision.
  • According to Franchak, down the line it could offer more research applications that could help infants with developmental disorders, medical research and applied research.

  • difficulty functioning in society, at work, and in school
  • But the symptoms of schizophrenia vary widely from one person to another. In some people, the dissociated feelings caused by the illness are a constant part of life. In others, the symptoms will come and go. People with schizophrenia do not always act abnormally. They may appear perfectly responsible and in control, even when experiencing hallucinations or delusions.

      Currently Mars seems to be the most important aspect of space exploration. We are truly hoping that one day there can be humans on Mars. As of now however, a way to get a human back from Mars to Earth is not possible.

Top 10 Reasons Why the World Won't End in 2012 : Discovery News - 4 views

  • 10. Changes in the Sun's magnetic field will lead to powerful flares.
  • The bottom line is that no dragon's breath of flame will stretch across 100 million miles of space and blowtorch Earth. The largest solar flare recorded to date, on Nov. 4, 2003, spewed several billions of tons of plasma in Earth's direction. The flare's X-ray radiation that impacted our protective atmosphere had the equivalent radiation of 5,000 suns.
  • 4. An asteroid will smash into Earth. A threatening near-Earth asteroid that's gotten the most press is the 900-foot wide Apophis. But its chances of collision have been downgraded to 1 in 250,000 at its next close approach in 2029. In theory, an uncharted asteroid or comet could come out of the blue tomorrow. But if we don't know about it today, the Mayans certainly didn't know about it 1,200 years ago. Earth-killer impacts are tens of millions of years apart. So there's no reason to be a doomsday clock-watcher.
