The Upside of Dyslexia

There are more and more posts about the Upside of Dyslexia. When Ron Davis published his book ‘the Gift of Dyslexia’ a couple of decades ago, everyone’s view was aimed at the downside and the struggles of Dyslexia. 
Finally they are catching up to his perspective – in another decade they will maybe also accept his solution – to focus on that talent and use it to correct the shortcomings instead of looking at the deficit and trying to implement auditory correction.
 
I found this article very insightful:

 

 

THE word “dyslexia” evokes painful struggles with reading, and indeed this learning disability causes much difficulty for the estimated 15 percent of Americans affected by it. Since the phenomenon of “word blindness” was first documented more than a century ago, scientists have searched for the causes of dyslexia, and for therapies to treat it. In recent years, however, dyslexia research has taken a surprising turn: identifying the ways in which people with dyslexia have skills that are superior to those of typical readers. The latest findings on dyslexia are leading to a new way of looking at the condition: not just as an impediment, but as an advantage, especially in certain artistic and scientific fields.

Tucker Nichols

 

Dyslexia is a complex disorder, and there is much that is still not understood about it. But a series of ingenious experiments have shown that many people with dyslexia possess distinctive perceptual abilities. For example, scientists have produced a growing body of evidence that people with the condition have sharper peripheral vision than others. Gadi Geiger and Jerome Lettvin, cognitive scientists at the Massachusetts Institute of Technology, used a mechanical shutter, called a tachistoscope, to briefly flash a row of letters extending from the center of a subject’s field of vision out to its perimeter. Typical readers identified the letters in the middle of the row with greater accuracy. Those with dyslexia triumphed, however, when asked to identify letters located in the row’s outer reaches.

Mr. Geiger and Mr. Lettvin’s findings, which have been confirmed in several subsequent studies, provide a striking demonstration of the fact that the brain separately processes information that streams from the central and the peripheral areas of the visual field. Moreover, these capacities appear to trade off: if you’re adept at focusing on details located in the center of the visual field, which is key to reading, you’re likely to be less proficient at recognizing features and patterns in the broad regions of the periphery.

The opposite is also the case. People with dyslexia, who have a bias in favor of the visual periphery, can rapidly take in a scene as a whole — what researchers call absorbing the “visual gist.”

Intriguing evidence that those with dyslexia process information from the visual periphery more quickly also comes from the study of “impossible figures,” like those sketched by the artist M. C. Escher. A focus on just one element of his complicated drawings can lead the viewer to believe that the picture represents a plausible physical arrangement.

A more capacious view that takes in the entire scene at once, however, reveals that Escher’s staircases really lead nowhere, that the water in his fountains is flowing up rather than down — that they are, in a word, impossible. Dr. Catya von Károlyi, an associate professor of psychology at the University of Wisconsin, Eau Claire, found that people with dyslexia identified simplified Escher-like pictures as impossible or possible in an average of 2.26 seconds; typical viewers tend to take a third longer. “The compelling implication of this finding,” wrote Dr. Von Károlyi and her co-authors in the journal Brain and Language, “is that dyslexia should not be characterized only by deficit, but also by talent.”

The discovery of such talents inevitably raises questions about whether these faculties translate into real-life skills. Although people with dyslexia are found in every profession, including law, medicine and science, observers have long noted that they populate fields like art and design in unusually high numbers. Five years ago, the Yale Center for Dyslexia and Creativity was founded to investigate and illuminate the strengths of those with dyslexia, while the seven-year-old Laboratory for Visual Learning, located within the Harvard-Smithsonian Center for Astrophysics, is exploring the advantages conferred by dyslexia in visually intensive branches of science. The director of the laboratory, the astrophysicist Matthew Schneps, notes that scientists in his line of work must make sense of enormous quantities of visual data and accurately detect patterns that signal the presence of entities like black holes.

A pair of experiments conducted by Mr. Schneps and his colleagues, published in the Bulletin of the American Astronomical Society in 2011, suggests that dyslexia may enhance the ability to carry out such tasks. In the first study, Mr. Schneps reported that when shown radio signatures — graphs of radio-wave emissions from outer space — astrophysicists with dyslexia at times outperformed their nondyslexic colleagues in identifying the distinctive characteristics of black holes.

In the second study, Mr. Schneps deliberately blurred a set of photographs, reducing high-frequency detail in a manner that made them resemble astronomical images. He then presented these pictures to groups of dyslexic and nondyslexic undergraduates. The students with dyslexia were able to learn and make use of the information in the images, while the typical readers failed to catch on.

Given that dyslexia is universally referred to as a “learning disability,” the latter experiment is especially remarkable: in some situations, it turns out, those with dyslexia are actually the superior learners.

Mr. Schneps’s study is not the only one of its kind. In 2006, James Howard Jr., a professor of psychology at the Catholic University of America, described in the journal Neuropsychologia an experiment in which participants were asked to pick out the letter T from a sea of L’s floating on a computer screen. Those with dyslexia learned to identify the letter more quickly.

Whatever special abilities dyslexia may bestow, difficulty with reading still imposes a handicap. Glib talk about appreciating dyslexia as a “gift” is unhelpful at best and patronizing at worst. But identifying the distinctive aptitudes of those with dyslexia will permit us to understand this condition more completely, and perhaps orient their education in a direction that not only remediates weaknesses, but builds on strengths.

Danger of ADHD drugs and Antidepressants

Antidepressants and ADHD Drugs Top List of Most Violence-Inducing Drugs

Please note that antidepressants are not the only type of drugs associated with violent, homicidal behavior, but they are among the most common suspects. A study by the Institute of Safe Medication Practices published in 2010 identified no less than 31 commonly-prescribed drugs that are disproportionately associated with cases of violent acts. Topping the list is the quit-smoking drug Chantix, followed by Prozac and Paxil, and drugs used to treat ADHD.

The data was collected from the FDA’s Adverse Event Reporting System (VAERS), and it’s well worth noting here that only an estimated one to 10 percent of all side effects are ever reported to VAERS, so the fact that more than 1,500 violent acts were actually reported as being linked to any given drug is pretty amazing. The vast majority of side effects, regardless of what they are, are typically blamed on something else and connections are brushed aside as “coincidental.”

In all, five of the top 10 most violence-inducing drugs were found to be antidepressants:

  • Fluoxetine (Prozac)
  • Paroxetine (Paxil)
  • Fluvoxamine (Luvox)
  • Venlafaxine (Effexor)
  • Desvenlafaxine (Pristiq)

According to Professor Healy, a study by the Drug Safety Research Unit in Southampton showed that one in every 250 subjects taking Paxil or Prozac were involved in a violent episode. In a study group of 25,000 people, this included 31 assaults and one homicide. In 2011, a whopping 14 million prescriptions for Paxil and more than 25.5 million prescriptions for Prozac were written.11 This could potentially equate to some 158,000 drug-induced incidents of violence annually from these two drugs alone. As reported in the featured article:12

“Another study involving more than 9,000 subjects taking the antidepressant paroxetine (Paxil) for depression and other disorders showed that subjects experienced more than twice as many ‘hostility events’ as subjects taking a placebo.” … Healy suspects that the main causal factor behind suicide and violence toward others is increased mental and/or physical agitation, which leads about five percent of subjects taking antidepressants to drop out of clinical trials, compared to only 0.5 percent of people on placebos.”

Another two in that top 10 list of violence-promoting drugs are commonly-prescribed ADHD medications (including Strattera). When you consider that antidepressants and ADHD drugs are among the most prescribed types of drugs  in the US, the fact that so many of them are linked to increased rates of violence should be cause for pause.

 

Besides an increased risk of violent episodes, ADHD drugs such as Ritalin, Vyvanse, Strattera, and Adderall (and their generic equivalents) are also responsible for nearly 23,000 emergency room visits annually, as of 2011 statistics. Over a mere six-year span, there’s been a 400 percent increase in ER visits due to side effects of these drugs.

Size does Matter

ImageImage

Guess what? Apparently size does matter, researchers have found – at least when it comes to how fast words are recognised and processed. They are not talking about the actually size of a word, but the size in the meaning of the word.

Astonishingly, words like ‘ocean, cathedral, elephant’ are processed faster by the brain than words like ‘ant, cup, pin…’

I am surprised they didn’t try to find out how long it would take to comprehend ‘by, so, forth, while…’???

It might have taken them too long to get the answer to that one.
