      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,”

      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.

      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.

      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.

Human-To-Pet Transmission A Concern At The Onset Of Flu Season - 0 views

      Still doing research, more information should some out over time

      Who would of thought that there would be a concern of human and animals sharing flu's.
  • The first recorded, probable case of fatal human-to-cat transmission of the pandemic H1N1 flu virus occurred in Oregon in 2009, Loehr said. Details were published in Veterinary Pathology, a professional journal. In that instance, a pet owner became severely ill with the flu and had to be hospitalized. While she was still in the hospital, her cat - an indoor cat with no exposure to other sick people, homes or wildlife - also died of pneumonia caused by an H1N1 infection.

  • All of the animals' symptoms were similar to that of humans - they rapidly develop severe respiratory disease, stop eating and some die.
  • "All viruses can mutate, but the influenza virus raises special concern because it can change whole segments of its viral sequence fairly easily," Loehr said.
  • Veterinarians who encounter possible cases of this phenomenon can obtain more information from Loehr or Jessie Trujillo at Iowa State University. They are doing ongoing research to predict, prevent or curtail emergent events.

Babies Learn To Talk By Reading Lips, New Research Suggests - 0 views

  • Babies don't learn to talk just from hearing sounds. New research suggests they're lip-readers too.
  • 6 months, babies begin shifting from the intent eye gaze of early infancy to studying mouths when people talk to them.

  • quality face-time with your tot is very important for speech development – more than, say, turning on the latest baby DVD.
  • 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.
    • Katie Raborn
       
      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.
    • Katie Raborn
       
      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.

Can You Give the Flu To Your Dog or Cat? | Surprising Science - 2 views

      Should we come up with a flu vaccine for animals?
  • A group of veterinarians at Oregon State and Iowa State Universities is now looking into the risk of flu for an unexpected population that doesn’t have access to flu shots: dogs, cats and other household pets.
    • Alexis Ramsey
       
      Good Idea. Great minds think alike.
  • ...15 more annotations...
  • “We worry a lot about zoonoses, the transmission of diseases from animals to people,” said Christiane Loehr, a professor at the OSU College of Veterinary Medicine. “But most people don’t realize that humans can also pass diseases to animals, and this raises questions and concerns about mutations, new viral forms and evolving diseases that may potentially be zoonotic. And, of course, there is concern about the health of the animals.”
    • Alexis Ramsey
       
      If this was put out more, I bet people would take this seriously in America we treat our animals like our childern.
  • H1N1 (“swine flu“) and H5N1 (“bird flu”)
  • The first recorded instance, described in an article published by the team in Veterinary Pathology, took place in Oregon in 2009.
    • Alexis Ramsey
       
      Look at that article.
  • While a cat owner was hospitalized with H1N1, both of her cats (which stayed indoors and had no contact with other sick people or animals) came down with flu-like symptoms and eventually died. A postmortem analysis of their lungs and nasal cavities turned up the H1N1 virus

      Proof
    • Alexis Ramsey
       
      Articles are mainly focusing on H1N1.
  • “It’s reasonable to assume there are many more cases of this than we know about, and we want to learn more,” Loehr said.
  • “Any time you have infection of a virus into a new species, it’s a concern, a black box of uncertainty,” Loehr noted.
  • this news might trigger immediate concern,
    • Alexis Ramsey
       
      Shouldn't this be on the news then?
  • the flu could be passed from human to pet, mutate into a more dangerous form,
  • “We don’t know for sure what the implications might be, but we do think this deserves more attention.”
    • Alexis Ramsey
       
      I agree very much.
  •  
    A good question Alexis... I think that people would pay for a flu vaccine for their pets.
