ested the learning abilities of sleeping newborns by repeating tones that were followed by a gentle puff of air to the eyelids.
-
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.
-
-
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
-
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

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.

Technology called eye-tracking has been changed so now its small enough to examine toddlers views of the 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.
-
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.

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

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.

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

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.
-
-
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.
-
-
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.

At age 6 months babies brains gain the ability to control their attention.

Understanding General Canine Genetics - 0 views

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.
-
Dog size depends on the dog's "phenotype". This is influenced by both environmental and developments factors. Such as the heath and the way the dog grew up.

Human Vision Inadequate For Research On Bird Vision - 0 views
-
Through evolution, our colour vision has developed from a more primitive version.
-
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.

•Those who slept longer at night had lower body mass index (BMI), based on weight and height, than those sleeping less.

So youre telling me the exact opposite of what I've been taught. That sleeping actually helps LOWER the chance of obesity?
-
-
•For twins averaging more than nine hours of sleep, genetic factors accounted for about 32% of weight variations; for those sleeping less than seven hours, genetic factors accounted for 70% of weight variations. For those sleeping seven to nine hours, 60% of the variation was due to genetic factors. Other factors that affect BMI include environmental ones.
