Learning Related Visual Disabilities; Dyslexia & Dyseidesia & Irlen Syndrome

 

We use this term to highlight those difficulties which are firstly of a Visual nature, and that they have the flow-on effect of disrupting Learning.

When you consider the highly visual nature of the classroom environment there are some requirements upon a child's vision that are obviously desirable for them to learn well.

Healthy eyes, (allowing for the fact that not everyone has two eyes), good eye focus and good eye control for both the whiteboard and their books would of course be best from the first day of school. Higher level skills in Visual Information processing (including identification and discrimination, spatial awareness, and integration with other senses)  are soon needed if they are to keep up.

Children are quick to note that they are not doing as well as those around them, and their self-esteem can crumble quickly. Once their confidence has been undermined it can be especially hard to rebuild their desire to try again.

Many studies have been published in the journals, and we have tested entire school rolls in a number of local schools, and there are about 30% of children in the classrooms of the world who are visually disadvantaged for reading, writing & spelling tasks. This is a very high number, and those who are not helped end up doing poorly through their school years.

Please don't assume your child is seeing well, or visually efficient.

Bring them in for a Pre-School check with us so that we can give you the right understanding of their Visual Readiness to Learn.

It's about a lot more than just reading an eyechart!


Definition; Dyslexia in brief

        Dys-                means                 "it isn't working well"

               -lexia       means "words"                                         "reading, writing or spelling"

so,  Dyslexia          means                 " it isn't working well for reading, writing or spelling"

 

At VisionLink, we work to a definition based on the World Health Organisation's definition;

"Dyslexia is when a person has a strange degree of difficulty with reading, writing or spelling despite having the brains to do better, and despite having had the educational opportunity to have done better"

I use the word 'strange' in the definition to highlight that these kids are bright, it is not a judgement on their intelligence that they are struggling with words.

I like parents to be able to quote this definition, it is helpful for them to carry this definition in their head so they don't over-complicate the issues. I believe that they should be able to explain their child's disability simply and clearly to friends, family and teachers.

It is important for parents to realise that 'Dyslexia" is not a complicated term to use in discussion. It is a helpful label so that we all know approximately what we are talking about.

It is usually an inherited problem.

I provide Dyslexia screening services as part of my standard Behavioural Optometry routine.

I offer the additional service of detailed, in-depth measurement of Dyslexia and its severity using international standard psycho-metric tests for approximately $325. The detailed report that is then produced can be used in discussion with teachers, friends and family.

The challenge lies in reducing the imnpact of this Learning Disability for your child, and I have many resources for this.

Behavioural optometrists work to the model that "Vision derives meaning", so we do Visual/Perceptual re-training with our Dyslexic patients.

Definition; Dyseidesia in brief

        Dys-                means                 "it isn't working well"

               -eidesia   means " shape"                                         "recognising or recalling word shapes"

so,  Dyseidesia      means                 " it isn't working well for recognising or recalling word shapes "

 

This sub-type of Dyslexia describes the difficulty in reading caused by either;

  • an inability to recognize printed words - the word is not known 'in flash', and often still not known even after taking a longer look. For the child it is as if they have never seen the word before, or if they do suspect it is a little familiar, they are not at all sure of reading it/matching it against their 'templated memory' of the word.  (sometimes called Decoding)

  • an inability to recall the shape of an otherwise known word such that they cannot write it down with correct spelling. The child may have a multitude of mis-spellings in their visual memory but have no confidence as to which one, if any, may in faact be worth the risk of committing to paper.
    (sometimes called Encoding)

  • or both of the above

This can be an embarrassing situation for the chld and a frustration for parents and teachers who know the child knew the word just a day or so before.

Such children generally have a good grasp of phonetic concepts, so teachers/tutors/parents efforts to belabour phonics-based (multi-sensory linguistic) approaches will not help at all. Indeed it risks only increasing confusion and stress because the student is being told again and again that it they work hard at perfecting their phonics skills it will get better yet the child and the tutor know its not working.

This can be soul-destroying for the child, and as self-esteem drops, so will alternate behaviour increase, often leading to anger and aggression.

Adding in this extra detail to the definition of Dyslexia based on the World Health Organisation's definition the full definition ends up being such that a person may be described as having;

"Dyseidesic form of Dyslexia is when a person has a strange degree of difficulty with reading, writing or spelling despite having the brains to do better, and despite having had the educational opportunity to have done better"

I use the word 'strange' in the definition to highlight that these kids are bright, it is not a judgement on their intelligence that they are struggling with words.

Adaptive technologies, in particualr Electronic Spellcheckers and Grammar checkers have a valuable role to play providing a workaround. Better quality proprietary software does a better job than the free spellcheckers that come with word-processing software - Click here for more info


Definition;Dyscalculia in brief

Dys-                   means "it isn't working well"

         -calculia  means " to calculate"               " perform simple mathematical functions" so,

 Dyscalculia     means " it isn't working well for performing simple mathematical functions "

This can be an embarrassing situation for the chld and a frustration for parents and teachers who know the child is clever enough to do the simple calculations (adding, subtracting, multiplying and division) based on their performance in other learning areas but just cannot get the knack of it.

So putting it together,

"Dyscalculia is when a person has a strange degree of difficulty with simple maths calcualtions despite having the brains to do better, and despite having had the educational opportunity to have done better"

This is in the group of Learning Related Visual Disabilites because the brains ability to visualize the physicality of the object being manipulated before the actual calculation. Even if the question and answers are being conducted aurally, the child bneeds to visualise the required manipulations and answers.

The child needs strong internal visualization of the principles of Length, Volume, Space, Quantity before they can begin to manipulate the numeric code on the page.
