your world with cunning Between the middle of the struggle for power that is in Argentina with the peeling problem with the "newsprint" and against government persecution to the media decided to get in tune with it and share with you a publication of the newspaper
"The New York Times" , which I have in my possession by paper and not via the Internet. A non-privileged? I do not want to be mean, it is therefore that I share with my dear readers who visit daily a part of me, the blog. With two cameras
subject to their heads and carrying backpacks equipped with wireless transmitters, infants and young children seem to crawl and walk cyborgs while reeling from the playroom.
A camera is pointed in the right eye and another to the field of view, and both sent videos to monitors that are nearby. When you combine the transfers, the result is a recording in which the reference points marked white cells of the eyes of a child.
Scientists use eye-tracking system to find out how children see the world while figuring out how to interact with it. In the laboratory, children over 5 months they cross an obstacle course of slopes, cliffs, paths and wooden steps adjustable. And to make it harder to challenge, sometimes kids dress shoes covered with Teflon or weight vests.
The researchers hope to understand what makes a child respond to another, as infants coordinate their look with their hands and feet to go around obstructions or handle objects, and how they adapt to small changes, such as slippery shoes.
The findings provided by the eye trackers suggest that infants may be better able to understand and act upon what they see than what they previously thought. "Looks fast
the obstacles facing them or their mothers' faces may be all they need to get the information you want " said John Franchak, a doctoral candidate in developmental psychology at the University of New York. "They seem to be surprisingly effective
".
Although it might seem that the vision does not require effort, we choose to do, making approximately two to four eye movements per second for a total of 150 000 daily movements said Karen Adolph, also a psychologist at the University development New York. "
's vision is not passive " he said. "
actively coordinate our eye movements with the movements of our hands and body .
eye trackers used by several Adolph, Franchak and his colleagues are based devices developed during the last decade by the New Yorker POSITIVE SCIENCE company with funding from the Laboratory U.S. Naval Research. Eye trackers are designed to help scientists discover things like how fighters detect camouflaged targets in the field. To adapt the eye trackers children, Jason Babcock, founder of POSITIVE SCIENCE, used padded headbands, spandex caps and Velcro strips to keep the cameras move. The head device weighs only 45.36 grams.
"
The beauty of this is how it helps capture what babies are thinking about this natural behavior " said Mary Hayhoe, a specialist in psychology of perception at the University of Texas at Austin. "As they seek is related to their actions at the time, tracking eye movements also allows for a straightforward reading of what might be happening in their heads"
In studies of six babies of 14 months which allowed to roam through a playroom filled with colored balls, stuffed animals and carts, the researchers found that almost a quarter of all encounters with obstacles, the babies were able to advance and avoid them without focusing your eyes on them.
"
These findings suggest that children may not have to do for a long time to get the information they need, either of people or objects "said Jeffrey Lockman, a specialist in developmental psychology at the University of Tulane."
This provides new insights into how much information they need, or how fast children can process this information .
