This is the first insight on autism that I have seen that begins to make sense to me. I became familiar with autistic individuals at an institution I worked at forty years ago and soon understood that this was not a case of mechanical impairment, but rather a case of circuitry impairment. This item suggests the possibility of over responsive circuitry. That certainly better fits the observational situation.
It is possible with great effort to communicate with such a child, but requires dedication and lots of time. Not surprisingly, when not provided the child does not get necessary emotional support and for that reason autistic children have also been thought of as emotionally disturbed.
This informs us that the perceptional interference prevents emotional development that must be overcome first. Successes occur usually because a parent has been there 24/7 to support the child.
The data suggest enhanced focus overcoming other inputs. There is nothing wrong with this particular talent. What is obviously wrong is that the individual is unable to control or shape the impulse in order to manage his environment both social and physical.
This flaw appears to be minor in practice and not actually debilitating at all if it could be turned off and on. I suspect that it could be turned off and that the individual turns immediately to a normal life. It may be caused by a physical flaw or affected by a simple targeted imbalance. Let us hope this leads to clearer thinking by researchers. The loss is too great.
Extraordinary Perception
We think of people with autism as having a deficit in cognitive processing—but their distractibility could also result from having enhanced perceptual capabilities

When Pulitzer Prize–winning music critic Tim Page was in second grade, he and his classmates went on a field trip to Boston

Page received an unsatisfactory grade on his essay. What’s more, his irate teacher scrawled in red across the top of the essay: “See me!” As he recalls in his new memoir Parallel Play (Doubleday, 2009), such incidents were not uncommon in his childhood, and he knew why he was being scolded: “I had noticed the wrong things.”
A Question of Focus
The subtitle of Page’s memoir is Growing Up with Undiagnosed Asperger’s, and indeed Page didn’t learn until age 45 that he suffers from what is called autism spectrum disorder, or ASD. ASD is usually defined by impairments in social interaction and communication, but many people with autism and Asperger’s syndrome (in which symptoms are milder) also tend to fixate on and remember seemingly irrelevant information in their world. Their attention seems to be awry, or to use Page’s words, they notice the wrong things.
But why? What’s going on in the autistic mind that makes the details of bus routes infinitely fascinating? Why are people like Page so easily distracted from the main act? Psychologists at University College London think that it might be a mistake to consider such distractibility as simply a deficit. To the contrary, Anna Remington and John Swettenham and their colleagues speculate that people with ASD might have a greater than normal capacity for perception, so that what appears as irrelevant distraction is really a cognitive bonus. They decided to test the idea in the lab.
Selective Attention
Remington and Swettenham studied a group of people with autism spectrum disorder, most of whom had Asperger’s, along with normal controls. They asked all the subjects to look at a computer screen, which displayed various combinations of letters and dots forming a ring. The subjects were instructed to very rapidly determine if the letters N or X were present in the ring and then hit the corresponding key on the keyboard. Some of the circles—those with more letters—were more difficult to process than others. There were also other letters floating outside the circle, but the subjects were specifically instructed to ignore those letters. Those floating letters were the laboratory equivalent of an irrelevant distraction in the real world.
The psychologists were measuring perceptual capacity—that is why they varied the complexity of the task. As expected, everyone was slower at the task when the ring contained more letters. The researchers were also measuring distractibility. When a letter outside the ring was one of the target letters (N or X), the subjects often took a longer time finding the N or X in the ring—indicating they were distracted by the presence of a target letter in the location that they were supposed to ignore.
The psychologists reasoned that as long as the subjects’ total perceptual capacity was not exhausted, they would also process the irrelevant, distracting letters within their visual field. Once they had surpassed their perceptual capacity—once the ring of letters was sufficiently complex—irrelevant processing would stop. So if ASD subjects in fact have greater processing capacity, then they should process more distracting information even as the main task becomes increasingly complex.
Seeing the Bigger Picture
And that is exactly what they found. As the researchers reported online in the journal Psychological Science, although there was no difference among subjects in either reaction time or accuracy on the main task, those with ASD processed the irrelevant letters while solving much more complex problems. Their reaction times indicated that they were still noticing when the extra letter was an N or X, while also finding the target letter in the ring with the same speed and accuracy as the normal controls. Put another way, they weren’t ignoring the main task, nor were they distracted away from it. Instead they were completing their work and moving on, using their untapped capacity.
But here’s the rub. Although this increased distractibility may be a talent rather than a deficit, the psychologists point out, it nonetheless can have detrimental consequences in real-life situations. Just ask Tim Page about his uncanny facility for bus routes.
