When it comes to disorders of Ray ban sunglasses the mind, our society has a tendency to seek out the safety of clear-cut categories. We want there to be a bright line separating normal from abnormal, health from sickness.
Alas, the human brain is a category buster, an organ so complicated that it continues to surprise and confound.
Consider autism. In recent years, autism has received an increasing amount of attention, largely because of a dramatic increase in its incidence. According to a new report from the Centers for Disease Control, about 1 in 88 children is now diagnosed with autism-spectrum disorders, which include "classic" autism as well as Asperger syndrome.
These diagnoses are often based on observed deficits in social interaction, such as a lack of eye contact or verbal conversation. Temple Oakley sunglasses Grandin, a noted autistic doctor, describes the experience of spending time with nonautistics as akin to being "an anthropologist on Mars."
Because of these obvious shortcomings—humans are supposed to be social animals, after all—most people regard autism as a disease, a straightforward example of an impaired mind. But there's compelling evidence that autism is not merely a list of deficits. Rather, it represents an alternate way of making sense of the world, a cognitive difference that, in many instances, comes with unexpected benefits.
That's the lesson, at least, of a new study from the lab of Nilli Lavie at University College London. A few dozen adults, both with and without autism, were given a difficult perceptual task, in which they had to keep track of letters quickly flashed on a computer screen. At the burberry handbags same time, they also had to watch out for a small gray shape that occasionally appeared on the edge of the monitor.
When only a few letters appeared on the screen, both autistic and normal subjects could handle the task. However, when the number of letters was increased, subjects without autism—so-called neurotypicals—could no longer keep up. They were overwhelmed by the surplus of information.
Those adults with autism didn't have burberry watches this problem. Even when the task became maddeningly difficult, their performance never flagged.
What explains this result? According to the scientists, autism confers a perceptual edge, allowing people with the disorder to process more information in a short amount of time. While scientists have long assumed that autistics are more vulnerable to distraction—an errant sound or conversation can steal their attention—that's not the case. As Prof. Lavie notes, "Our research suggests autism burberry ties does not involve a distractibility deficit but rather an information-processing advantage."
These perceptual perks have real-world benefits. The scientists argue, for instance, that the ability to process vast amounts of data helps to explain the prevalence of savant-like talents among autistic subjects. Some savants perform difficult mathematical calculations in their head, others draw exquisitely detailed pictures at a young age. These skills have long remained a mystery, but they appear to be rooted in a distinct cognitive style shared by all autistics. Because they can process details that elude the rest of us, they can perform tasks that seem impossible, burberry outlet mens belts at least for the normal mind.
The same logic applies to many supposed mental disabilities. In recent years, scientists have demonstrated that people with attention-deficit disorders typically demonstrate higher levels of creative achievement in the real world, such as publishing fiction or winning prizes at science fairs.
Those with dyslexia, meanwhile, are often better at peripheral perception and quickly grasping the gist of a scene, showing superior performance on a variety of visual tasks. This might explain the high number of artists and designers with the condition.
The larger lesson is that, according to the latest research, these "deficits" are actually trade-offs. Carrera sunglasses, cheap porsche carrera sunglasses, 50% sale. What seems, at first glance, like a straightforward liability turns out to be a complex mixture of blessings and burdens.
For too long, we've assumed that there is a single template for human nature, which is why we diagnose most deviations as disorders. But the Louis vuitton men shoes 2012 designer style online discount gray reality is that there are many different kinds of minds. And that's a very good thing.
