Post #15 Learning Disabilities What? Types
Abraham Verghese, through the voice of one of his doctor characters, offers us a healthy caution before we review the types, each with their individual labels.
Our brains have extraordinary capabilities. In our simplistic understanding, we put each function in its box – Broca’s area for speech, and Wernicke’s area for interpreting what we hear. But the boxes are artificial. Simplistic. The senses intertwine and spill over from one area to another.[i]
Once again I begin with (admittedly a rearrangement) of Grok’s tidy overview providing the list of types of learning disabilities with the DSM-5 as reference. And heads up: a person can have more than one of the following issues.
Dyscalculia: difficulty understanding numbers, memorizing math facts, grasping time/money concepts.[ii] Other terms used are ‘math learning disorder’, ‘math learning disability’ and ‘math disorder’.
Dysgraphia: poor handwriting, trouble organizing thoughts on paper, spelling issues.[iii]
Dyslexia: difficulty decoding words, poor spelling, slow reading but not slow thinking, trouble with phonological awareness [by which is meant] the functional part of the brain where the sounds of language are put together to form words and where words are broken down back into these elemental sounds… of language… The Shaywitz family refer to this as a ‘glitch’.
The DSM-5 now uses the label ‘Specific Learning Disorder’ rather than Dyslexia to allow for learning variables and the variety of impacts of alternate wiring in the brain.[iv]
Auditory Processing Disorder: trouble distinguishing similar sounds, following verbal instructions.
Visual Processing Disorder: difficulty with reading maps, recognizing shapes, spatial organization.
Nonverbal Learning Disability: strong verbal skills but poor motor, visual-spatial, and social abilities.
Dyspraxia: difficulty with handwriting, tying shoes, sports, sequencing movements.
Executive Functioning Deficits: challenges with planning, organization, time management, working memory and self-regulation.
This seems a comprehensive list and yet I have come across other labels as well. Whether this makes the list complete or not, I am not sure anymore, but here are the others I have found.
Specific Reading Comprehension Disabilities(S-RCD): phonological and word recognition skills which are the opposite pattern to dyslexia. [v]
Mixed Reading Disabilities: problems with both word recognition and language comprehension because of weaknesses in vocabulary or other language areas that also affect their reading comprehension. [vi]
Language-based Learning Disabilities/Developmental Language Disorder (DLD): ‘unexpected’ and more severe difficulty acquiring and using spoken and/or written language despite normal intelligence and hearing.[vii]
Sally and Jonathan Shaywitz want their readers to know Dyslexia is pain. It represents a major assault on self-esteem.[viii] I think it is safe to say that anyone living with any of the above difficulties would nod in agreement.
I appreciate how Phil Hanley illustrates this pain.
When I was a kid, I was desperate for people to see me as anything but a special ed student. I tried to conceal my dyslexia from the world the way one hides a hickey from their parents at the breakfast table. I attempted to use my appearance to distract from my learning difference. So, when I developed a love for Bob Marley at age eleven, I decided to grow dreadlocks. They would be the perfect smokescreen. When a white person has dreads, no one wonders what else is wrong with them.
As an adult Phil Hanley met someone who was modeling but was also trained as a lawyer. Hanley couldn’t imagine anyone modeling if he or she could read. He’d chosen modeling only because he believed that any career involving reading was out for him. Hanley was writing of the years he was a model but ashamed to let his hometown friends know what he was doing to make money. Why did I still hide my career? Why had shame followed me cross the Atlantic? My shame stemmed from a lifetime of embarrassing moments caused by dyslexia. I was embarrassed that I was the only one who got a zero on spelling test. Embarrassed that I was constantly being taken out of class and forced to go to the Learning Resource Center. Embarrassed that I needed more time to finish tests. Embarrassed that even with all these allowances, I still ended up in special ed.
Embarrassment is fleeting; it surfaces, then fades. Shame is enduring; it stays with you like a criminal record or the theme of the television show Muppet Babies.
He saw himself as the world’s slowest learner. I still struggle with concepts taught in first grade, a major assault on his self-esteem.[ix]
Yet Hanley is now a renowned comedian and writer, turning his struggles into a successful, creative career. That is the surprising ‘unexpected’ part of Dyslexia for while the reading impairment is evident, there is so often this other side of the coin for people living with dyslexia, creativity. A quick Google provides a list of successful dyslexia creatives.
We believe that the resolution of this paradox [between impairment and creativity] lies in the problematic but undoubtedly real distinction between declarative and procedural knowledge, between explicit and implicit knowledge, and between explicit and implicit learning… Reasoning ability does not depend fundamentally on fluency. …analytic, creative and practical [learning] … [depend] directly on skill or fluency…[x]
Myths that have built up around children and learning.
Yasik does remember mixing up his ‘d’s and ‘b’s early on. For those of us who knew little about learning disabilities the ‘d/b/p’ mix-up was a simple enough explanation to satisfy us. And for that mix-up all we needed to do was find this slide-like device that isolated letters on the page for our child to be able to move ahead in reading.
Enter the next ‘however’. Apparently… letter reversal is quite common in the early stages of reading – for any child. Is that all it was for Yasik? I actually have problems mixing the ‘d/b/p’ as well at times – tired eyes, menopause?
Sally and Jonathan Shaywitz tell us there is no evidence that they actually ‘see’ letters and words backward. But naming the words was difficult – kids write ‘was’ but say ‘saw’ … The problem is a linguistic one, not a visual one….
They also brush off the possibility of mirror writing, writing backward and reversing letters and words. Apparently…this also happens in dyslexic and non-dyslexic children.[xi]
Phil Hanley suggest dyslexia also explains his hopelessness in sports: I was the skinniest kid with the least skills. Dyslexia affects hand-eye coordination and depth perception, two things needed in any athletic endeavor.[xii] In response, the Shaywitz family say that while clumsiness, left-handedness, difficulties with right-left orientation, and trouble tying shoelaces may be “side symptoms” for some dyslexic people, they are not “core” aspects of dyslexia. They may be elements of Dyspraxia though.
So many people have a right-left orientation frustration that store clerks are told to help hapless customers when necessary. I certainly have a problem with this in two languages. But alas I can no longer call it my dyslexia.
Not only does Dyslexia share some side symptoms with non-dyslexic people, it is also gender neutral for though it has long been thought that more males have dyslexia, it turns out that maybe the females were simply quieter about their struggle with reading.[xiii]
And in response to the idea that our brains process writing differently based on the different ways languages are written: a child struggled with dismal inability to read in English in his American school. The family moved to Japan when the child was a teen. In Japanese the teen was very successful at reading. The different ways languages are written was the explanation. Nonetheless there remains some mystery to the teen’s success for the Shaywitz family say it is a myth that dyslexia occurs only in a few countries or alphabet-based languages.[xiv]
