Dyslexia and pre-med

Stephen Harris, who is pursuing an undergraduate degree in hopes of studying medicine, has dyslexia according to a story by Diana McKeon Charkalis published in USA Today. Ms. Charkalis features another aspect of Mr. Harris’ background—he played bass guitar under the stage name, “Kid Chaos”—in her story, a story that gets some things right and, sadly, some things wrong. Here’s Ms. Charkalis’ lead

As a kid growing up in Wales, Stephen Harris thought about becoming a doctor. But bad grades discouraged him, so he turned to music at age 11.

“I started playing guitar, and it was a practical thing that I could do well,” he says. “Success came when I was 18. I had already been out of school two years and, suddenly, I was on the front page of magazines.”

A bass player sporting long hair, leather and tattoos, Harris adopted the stage name Kid Chaos and performed at Madison Square Garden before he turned 21. The boy who had failed in school flourished on stage, and he toured with bands including goth rockers The Cult and Guns N’ Roses.

As Ms. Charkalis reports, Mr. Harris later returned to post-secondary education and, thanks to efforts by the Learning Disabilities office of a communnity college, learned that he has dyslexia. Four years later, he is progressing through a pre-med program of studies and hoping to attend a medical school in Wales (UK).

I find it valuable that Ms. Charkalis has covered this story. As an illustration of how people can persist—and succeed—in the face of disabilities, it is a worthwhile one. But it is also flawed, perpetuating some misinformation about dyslexia. Here are examples:

  1. The article cites the National Center on Learning Disabilities as saying that “twenty-five million Americans have a learning disabilty.” That’s ~8.5 of the population (based on an estimated population of 295,734,134 (see the World Factbook from the US Central Intelligence Agency). This estimate is within reason, but it is only an estimate and there is wide variation among the estimates. Because LD is an educationally determined diagnosis, the only fact-based numbers on this topic for the US come from the annual child counts in the public schools. For example in 1999-2000 according to the US Education Department’s Report to Congress, there were 2,871,966 (4.5% based on the estimated resident population) children aged 6-21 who had been identified by the public schools as having LD. To be sure, for various reasons (age range represented; private school attendance; misdiagnosis; socio-cultural resistance to labeling; etc.) these numbers may be too low or high, but they represent the best data we have. Although some might consider this point mere quibbling about numbers, I submit that it is important to be clear about the people whom we identify as having LD; by using relatively unfounded estimates, we risk mitigating the importance of LD. (This is not a question about Mr. Harris’ diagnosis; I’m talking about the concept of LD here.)
  2. Ms. Charkalis reported that Mr. Harris “realized…that he understands things best visually and needs learning to be a hands-on experience.” Mr. Harris may have reported this observation to Ms. Charkalis and he may well believe it. Whether it is true in an objective sense, however, is open to doubt. Sadly, special educators and others have sometimes misled people to look at aspects of learning that have little objective reality. In my squishy periods, I am willing to go out on a limb and suggest that some activities are more visual (distinguishing colors) or auditory (playing the bass), but my antennae become extended and erect when I catch a whiff of typing learners by modality. Even though we may interpret our own experiences as reflecting modality preferences, there is little or no evidence that we can reliably identify modality types of learners nor that types of learners benefit from modality-differentiated teaching.
  3. A sidebar to the article refers to the Council for Exceptional Children (CEC; hooray) and then offers a list of 28 famous individuals said to have dyslexia. Two issues:
    1. The juxtaposition of CEC and the list of names makes it easy to infer that the list came from CEC. I searched the CEC site and found few references to the half-dozen names from the list that I entered.
    2. Although some of the people on the list may have had an actual diagnosis of dyslexia, the determination of dyslexia for many of them probably is based only on someone’s analysis of historical data that do not include the quality of evidence permitting a definitive diagnosis. Identifying famous historical figures as having dyslexia (or other disabilities) may serve the purpose of inspiring others to achieve or to accept dyslexia, but in can be misleading, too. Not all individuals with dyslexia will achieve such note. Furthermore, as I’ve argued previously, motivating individuals with LD is not sufficient to help them achieve and probably the most effective way to increase motivation is to help people with LD succeed on important tasks.

Mr. Harris’ efforts and growing success illustrate this last point. It is wonderful to know that he is persisting and progressing. I wish him well. Thanks to Ms. Charkalis for bringing the story to the public.

1st-person LD

In a first-person article, Mary Kobes of NJ (US) relates her experiences about learning to read print and music. It’s a disarmingly unassuming article, a perspective that many of may miss.

I remember I learned to read, when I was7 years old and in the 2nd grade. It was a long road ahead for me. There were many experiences and obstacles I had to face. Some were more difficult than others. Some of the main obstacles I faced were that I couldn’t talk, I couldn’t read and most importantly I was classified with a learning disability, which held me back from a lot of things.

Milwaukee newspaper editorial

In an editorial about a special education class action suit, the Milwaukee (WI, US) Journal Sentinal got it spot-on right! After remarking on the obligation of the Milwaukee Public Schools to provide a free and appropriate publice education for students with disabilities and the failure of the local education agency (LEA) to identify children with Learning Disabilities, the un-named editorial writer notes that a magistrate encourage the plantifs and the LEA to negotiate a settlemenet.

Great idea.

Defending against the lawsuit is a waste of money that would be better spent on improving the education of students with disabilities. Happily, all sides are expressing a willingness to talk and, importantly, to listen. They mustn’t lose sight of the goal: a more effective education.

Bingo! What a refreshing view. I’m writing a letter to the editor.

Going backwards

In the 60s when I first began working with students with Learning Disabilities, we often emphasized activities designed to promote perceptual and motor development. We were operating on the theory that motor development undergirded cognitive development; that correcting underlying motor and perceptual problems would provide a foundation for better cognitive development; and that having children walk on raised beams, make “angles in the snow,” practice eye-hand coordination, and so forth would help correct those underlying problems and, indirectly, help with academic learning. After scores of studies, we realized that those activities aided perceptual and motor skills, but had no benefits on skills such as reading, writing, computing, and such.

Welp…it’s back! There are Web sites and more. For example, I found the same balogna in an article with the title of “New Brain Fitness Device Help Children with Learning Disabilities.” It refers to Frank Belgau, once identified as “director of the Visual and Motor Control Lab at The University of Houston,” who has equipment and training seminars for sale at Learning Breakthrough and Balametrics
Here’s a snippet.

The Learning Breakthrough Program is a balance and sensory activity program designed to help better organize brain processing. The program entails a child watching a DVD or VHS which takes him or her through tasks such as throwing beanbags, tossing balls at a bounce back target while standing on a unique balance board or tapping a hanging ball.

The article includes some contextual materials about LD that are actually pretty accurate. But it also includes lots of other matter of dubious nature. The Web sites give some background on the developer and even refers to research about it. The research is actually quite weak. There is what amounts to a testimonial and a reference to one study. The one study shows improvement in early adolescent students who received training, changes that are equally likely to be observed because of the passage of time or because individuals who have extreme scores at the first time of testing are likely to have less extreme scores on a second testing (regression to the mean). That study is available as a PDF from the Dore Achievement Center in the UK.

I have no problem with teaching children physical skills. Those are valuable in their own right. But, please don’t expect that improvements in perceptual-motor skills will lead to improved academic performance. These folks are showing us one weak study. That is not sufficient to outweigh the 180 studies that, in aggregate, show neglible benefits…and there’s another summary for which I don’t have a link.

More education writing

Over on I Speak of Dreams, Liz Ditz has an entry about a worthwhile story by an education writer. Given how often we point at their mistakes, it’s nice to catch one being good.

Still more brain effects

Adults with dyslexia who got intensive phonics instruction had improved decoding skills and changes in brain activity, according to reports about a study from several universities. Lynn Flowers, an assistant professor in the Department of Neurology at Wake Forest University in Winston-Salem and one of the researchers, studied 19 adults with dyslexia and 19 adults without dyslexia. The researchers require half of the adults with dyslexia to attend an eight-week intervention program three hours a day, five days a week.
After the instructional period, they retested the adults and obtained Functional Magenetic Resonance Images (fMRI) of the activity in their brains when they performed reading tasks. They found that the adults with dyslexia who received the training had significant improvements in reading and changes in brain activity while reading.

One more time: Maybe it’s behavior-brain relationships, not brain-behavior relationships.
