Visual-Spatial Dyslexia: Symptoms and Program

The terms auditory-linguistic dyslexia and visual-spatial dyslexia are often used by scholars to describe two main types of dyslexia.

The visual-spatial dyslexic, generally speaking, has problems remembering and discriminating visual gestalts. Mattis noted difficulties in visual-spatial perception and letter discrimination. Pirozzolo characterized such a child as having directional (left-right) confusions, poor visual-motor coordination with lower scores in performance areas, body concept disorders, finger agnosia, spatial dyscalculia, and poor visual imagery causing reversals and form confusions. Boder observed that children with these types of difficulties are audile learners, that is, they usually adopt a phonetic analytic rather than whole-word approach to reading, and Johnson and Myklebust noted their preference for auditory activities.

Some of the specific manifestations ascribed to this group of dyslexics, according to author Saroj D. Sutaria (Specific Learning Disabilities: Nature and Needs), include the following: visual discrimination difficulties, slow rate of perception, visual sequencing difficulties, visual memory disorders, deficits in visual analysis and synthesis, omissions, additions and substitutions, and losing place while reading.

1.) Visual discrimination difficulties

The learning disabled who have difficulties in visual discrimination are unable to recognize similarities and differences between letters and words. They especially find difficulty making differentiation between similar-looking letters such as /n/, /m/, /u / or /b/, /d/, /p/, /q/, etc., or between words such as /hat/, /hot/, /hate/ or /pug/, /bug/, or /no/, /on/, etc. Recognizing letters requires the ability to make rather fine discriminations which, in turn, is dependent on the ability to make gross visual discriminations. If larger forms like geometric shapes cannot be differentiated, then the subtleties of letters would elude the learning disabled. Three of the more common forms of discrimination problems to be noted in the learning disabled include reversals, rotations, and inversions.

  1. Reversals — The most common type of problem cited to exemplify reversals is the confusion between /b/ and /d/. This confusion represents the exact mirror-imaging that some learning disabled experience. When words containing /b/ or /d/ are read, they are frequently misread because they have been perceived oppositely, as, for example, /bad/ for /dab/, /big/ for /dig/, etc., or vice versa.
  2. Rotations — The form of the letter is rotated so that it is perceived differently; for example, the letter /b/ may be read as /p/ because the child has rotated the axis from its original upward direction to a downward direction, or confusing /b/ for /q/ which would be a rotation of a greater magnitude, with the axis seen as going down the opposite side.
  3. Inversions — A variation of both reversal and rotation is an inversion. The letter form is inverted. Thus, the child may confuse /n/ with /u/ and /m/ with /w/, etc.

Overcoming Severe Dyslexia: Maddie’s Diary (A Live Case Study)

Meet Maddie, a 10-year-old who has been diagnosed with severe dyslexia, moderate dyscalculia, ADHD, and low IQ (low 80s). People who have evaluated her have said that they have never seen dyslexia as severe as this before. Her parents have been told by more than one professional that Maddie will probably never read…

2.) Slow rate of perception or hesitation

The learning disabled child’s oral reading is slow and labored. This is especially so because the child is not able to form visual perceptions at the rate considered normal for age. The child may be observed to look at a visual stimulus (fixation) a long time or repeated times before he/she will respond to it. There is also a greater tendency to regress to a previously recognized form while the hesitancy or uncertainty lasts.

3.) Visual sequencing difficulties

The child who is unable to retain the visual sequence in short-term memory long enough to be able to recall it or who, because of a lack of left-to-right directional tracking with the eyes, misperceives the order in which the letters appear in the words, will read them incorrectly. For example reading /god/ for /dog/, /was/ for /saw/, /nap/ for /pan/, etc. This is not to suggest that the sequencing disruption affects only the first and last consonants. The sequencing disruption can take place in any position. For example, the word /story/ could be read as /stroy/, /tow/ as /two/, /kitchen/ as /chicken/, etc.

In compound words, entire syllables could be reversed: for instance /yardstick/ read as /stickyard/, /horseshoe/ as /shoehorse/, etc. The learning disabled show an abnormal saccadic pattern.

4.) Visual memory disorders

Deficits in visualization of letters and words, that is, what they look like in their physical characteristics, affect the ability to develop sight recognition of words. The learning disabled that has especial problems in this area approaches each word as though for the first time. Even when words are repeated, the child cannot recall them. The child is unable to process short- and long-term storage and retrieval efficiently in order to make the needed associations between the visual and the auditory or linguistic aspects of the word. In other words, visual imagery is poor. This has a serious consequence because so many words in the English language cannot be sounded out. The tendency to guess at the word from its size is often observed.

5.) Deficits in visual analysis and synthesis

In order to read fluently the child must be able to recognize words as units, each having a separate entity or a configuration. Within each word, the child must recognize each letter and its relation to the others in the word. The child with a difficulty in visual analysis would be unable to find a given letter in the alphabet, a smaller word in a larger word, a word in a sentence, a sentence in a paragraph, etc., primarily because of the array of competing visual stimuli and the child’s difficulty in breaking the stimuli down into component parts. In other words, the foreground-background disturbance interferes with the child’s ability to succeed in the task. Visual synthesis requires putting the pieces together to compose a whole. Sometimes a few pieces may be missing. Nonetheless, if enough stimulus is present to provide the needed clues to the missing parts, the child should be able to guess the word. The child with difficulties in visual synthesis is unable to do so. In other words, the child is unable to use partial information to make a correct guess. Further, failure to perceive words as entities results in attention to single or isolated letters rather than words. Such a child also has problems putting two small words together to form compound words, to put syllables together to make a word, to unscramble letters to make a word, and/or to unscramble words to make a sentence.

6.) Omissions, substitutions, additions

Perhaps the most common omission in a young learning disabled child’s reading is the punctuation mark. The child’s oversight of the punctuation marks causes the child’s reading to lack inflection and variation. The pauses which the child makes may be several, but they usually occur at the wrong places because of hesitations. In addition to missing punctuations, many of the smaller words such as articles are also frequently missed. Sometimes parts of words, especially the endings, or descriptive and more difficult words may be missed. For instance, the child may read /A boy went walk/ for /A boy went walking/ or /a dog/ for /a fierce dog/, etc. The learning disabled also tends to substitute letters and sometimes whole words. Instead of reading /father/, the child might read /dad/, which is a meaningful linguistic substitution but nonetheless, an error from the visual decoding aspect. Critchley noted substitutions of opposite meaning, such as /this/ for /that/, /his/ for /her/, etc. Additions are also frequently noted. For instance, if the story started with /Once there was/ the child reads /Once upon a time there was/, etc.

7.) Losing place while reading

The learning disabled child’s difficulty in making left-to-right tracking movements has already been noted. We have seen how this disrupts sequencing of letters and syllables in words. This difficulty also causes the child to lose his/her place in reading. The child may skip to the next line of print, often unaware that he/she has done so, or have difficulty switching from one line to the next. The inability to keep place also shows up when someone else is reading and the learning disabled is required to follow along.

How can Edublox help?

The Edublox point of view, based on the latest research, is that dyslexia is not a DISability but simply an INability. While there are other causes, the most common cause of dyslexia is that the foundational skills of reading and spelling have not been mastered properly.

Learning is a stratified process. One step needs to be mastered well enough before subsequent steps can be learned. This means that there is a sequence involved in learning. It is like climbing a ladder; if you miss one of the rungs of the ladder, you will fall. If you miss out on one of the important steps in the learning process, you will not be able to master subsequent steps.

A simple and practical example of this is the fact that one has to learn to count before it becomes possible to learn to add and subtract. If one tries to teach a child to add and subtract before he has been taught to count, one will quickly discover that no amount of effort will ever succeed in teaching the child these skills.

This principle is also of great importance on the sports field. If we go to a soccer field to watch the coach at work, we shall soon find that he spends a lot of time drilling his players in basic skills, like heading, passing, dribbling, kicking, etc. The players who are most proficient at these basic skills usually turn out to be the best players in the actual game situation.

In the same way, there are also certain skills and knowledge that a child must acquire first, before it becomes possible for him to become a good reader. Edublox Online Tutor offers multisensory cognitive training, aimed at developing and automatizing the foundational skills of reading and spelling, and application in the form of reading and spelling exercises.

Hard work pays off 

Carole Derrick, a teacher in the US, reported: “After working for 6 weeks with Allen who is functioning at a non-reader level with a fragile self-esteem, I have witnessed academic progress as well as a boost in self-confidence… Allen’s difficulties with dyslexia has improved. In the first 3 weeks of the program, Allen was reversing letters frequently (b for d; on for no). If such reversals occur during the 6th week, he usually corrects himself.”

Mrs. K. G. Robertson wrote: “My son has tried the following: Remedial teaching, extra lessons and occupational therapy. Unfortunately, although there was an improvement my son’s problem remained. This resulted in him avoiding any reading and writing. He developed behavioral problems. He was ashamed of his dyslexia. We started your program and within a period of two months he improved to the extent that he will pick up and read a newspaper or magazine of his own free will – without prompting. He has stopped reversing and substituting the letters b, p, and d. He writes messages freely. Your program has made an immense difference.”
