    • 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

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.

  • 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.

      The toddlers didn't have to look at the obstacle all the time. they were able to use information for their peripheral vision.

  • 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,

  • Other studies have shown that babies who are best at distinguishing between vowel sounds like "ah" and "ee" shortly before their first birthday wind up with better vocabularies and pre-reading skills by kindergarten.
  • babies also look to speakers' faces for important social cues about what they're hearing
  • So he and doctoral student Amy Hansen-Tift tested nearly 180 babies, groups of them at ages 4, 6, 8, 10 and 12 months. How? They showed videos of a woman speaking in English or Spanish to babies of English speakers. A gadget mounted on a soft headband tracked where each baby was focusing his or her gaze and for how long.

      Lewkowicz and Hansen tested how babies learn
  • They found a dramatic shift in attention: When the speaker used English, the 4-month-olds gazed mostly into her eyes. The 6-month-olds spent equal amounts of time looking at the eyes and the mouth. The 8- and 10-month-olds studied mostly the mouth.

      Different age groups studied the speaker differently.
  • At 12 months, attention started shifting back toward the speaker's eyes.
  • at 6 months, babies begin observing lip movement, Lewkowicz says, because that's about the time babies' brains gain the ability to control their attention rather than automatically look toward noise.

  • In the dog, there are 78 chromosomes existing of 39 matched pairs which make up the dog’s “genotype”. On the other hand, the dog’s “phenotype” is what the animal actually looks like and this can be influenced by both environmental and developmental factors. For example, a dog’s adult size is partially determined by his genotype but is also influenced by such factors as health and nutrition as a puppy.

Human Vision Inadequate For Research On Bird Vision - 0 views

  • Through evolution, our colour vision has developed from a more primitive version.
    • Zaphron Richardson
       
      This is what made me look up about sight evolution in the first place. I wondered what colors that we cant see in the electromagnetic spectrum would look like, and perhaps humans used to be able to see more or different colors than we do now in earlier stages of our evolution. I then asked myself, what if the colors we see are the ones we need to survive? Maybe it is possible that those with a mutation that widened or altered the "visible" spectrum were not fit for survival long ago, and what we see now is the result of evolution of our species.
