3. DYSLEXIA
Historical Perspective
If a child's difficulty with
reading could not be
explained by low
intelligence, poor eye sight,
poor hearing, inadequate
educational opportunities,
or any other problem, then
the child must be dyslexic.
Simple Definition
Dyslexia is an inherited
condition that makes it
extremely difficult to read,
write, and spell in your
native language—despite at
least average intelligence.

6. A neurological model of dyslexia
Neurological model of dyslexia explains how a specific phonological deficit might
arise, Based on a review of the neurology of dyslexia, the model specifies that:
1) Genetically determined focal cortical anomalies in specific left perisylvian
language areas are the underlying cause of the phonological deficit;
2) This phonological deficit is the primary cause of reading impairment;
3) Under certain hormonal conditions during gestation, these cortical
anomalies induce secondary disruption in sensory pathways, notably in the
thalamus. The disruption may even extend to further areas, like the
posterior parietal cortex and even the cerebellum;
7. A Social Model of Dyslexia
Dyslexia is an experience that arises out of natural human diversity
on the one hand and a world on the other where the early learning
of literacy, and good personal organization and working memory is
mistakenly used as a marker of ‘intelligence’.
8. The Phonological Model of Dyslexia
•The phonological model of dyslexia argues that dyslexics have impaired
reading ability because they have a deficit in phonological processing.
• According to this model, dyslexics have a difficult time with written language
because they have an impaired ability to deconstruct written words into
phonemes, thus preventing word identification.
•This low level phonological deficit prevents words from reaching high level
linguistic processing, which would allow the reader to gain meaning from the
text.
•Thus, dyslexics have intact memory and comprehension language processes
that are not activated because they can only be activated after a word has
been identified through phonological processing.
10. SIGN AND CLUES OF DYSLEXIA…
• Diagnosed for the first time in third grade. Since
dyslexic readers often do not use a decoding strategy to
identify a word and instead rely heavily on the
surrounding context to figure out.
• Depend on context for understanding rather than
written words de-coding.
• Poor spelling is often a sign of dyslexia.
• Handwriting [can] be an important clue to dyslexia.

19. Causes And Types
There are several types of dyslexia that can affect the child's ability
to spell as well as read.
1. "Trauma dyslexia" usually occurs after some form of brain trauma
or injury to the area of the brain that controls reading and writing.
2. A second type of dyslexia is referred to as "primary dyslexia." This
type of dyslexia is a dysfunction of, rather than damage to, the left
side of the brain (cerebral cortex) and does not change with age.
Individuals with this type are rarely able to read above a fourth-
grade level and may struggle with reading, spelling, and writing as
adults. Primary dyslexia is passed in family lines through their genes
(hereditary). It is found more often in boys than in girls.
20. 4. Visual dyslexia is characterized by number and
letter reversals and the inability to write
symbols in the correct sequence.
3. A third type of dyslexia is referred to as
"secondary" or "developmental dyslexia" and is felt
to be caused by hormonal problems during the early
stages of fetal development.
Developmental dyslexia diminishes as the child
matures. It is also more common in boys.
Dyslexia may affect several different functions.
21. 5. Auditory dyslexia
involves difficulty with sounds of letters or
groups of letters. The sounds are perceived as
jumbled or not heard correctly.
6. Dysgraphia
refers to the child's difficulty holding and
controlling a pencil so that the correct
markings can be made on the paper.
22. Dyslexia Diagnosis
Dyslexia is a difficult disorder to diagnose.
The testing determines the child's functional reading level and
compares it to reading potential, which is evaluated by an
intelligence test.
All aspects of the reading process are examined to pinpoint
where the breakdown is occurring.
The testing assesses how a child takes in and processes
information and what the child does with the information.
The tests determine whether a child learns better by hearing
information (auditory), looking at information (visual), or doing
something (kinesthetic).
23. The tests assess and determines how the child can perform better
When allowed to give information (output),
When saying something (oral), or
When doing something with their hands (tactile-kinesthetic).
The tests also evaluate how all of these sensory systems (modalities) work in
conjunction with each other.
DYSLEXIA ASSESSMENT
Dyslexic Evaluation check Lists:
1.Dyslexia screening form
2.A check list for dyslexia
24. A standard battery of tests can include, but is not limited to, the
following:
1.Wechsler Intelligence Scale for Children-Third Edition (WISC-III)
2.Kaufman Assessment Battery for Children (KABC)
3.Bender Gestalt Test of Visual Motor Perception
4.Woodcock-Johnson Psycho-Educational Battery
5.Peabody Individual Achievement Tests-Revised (PIAT)
6.Kaufman Tests of Educational Achievement (KTEA)
7.Beery Developmental Test of Visual-Motor Integration
8.Test of Visual Perception (TVPS)
9.Test for Auditory Comprehension of Language
10.Stanford-Binet Intelligence Scale
11.Test of Auditory Perception (TAPS)
12.Peabody Picture Vocabulary Test-Revised
26. TYPES OF TREATMENT FOR DYSLEXIA
Before any treatment is started, an evaluation must be done to
determine the child's
Specific area of disability.
The plan may be implemented in a Special Education setting or in
the regular classroom.
An appropriate treatment plan will focus on strengthening the
child's weaknesses while utilizing the strengths.
A direct approach may include a systematic study of phonics.
( phonological approach)
There are many theories about successful treatment for dyslexia, there is
no actual cure for it. The school will develop a plan with the parent
involving occupational therapist to meet the child's needs.
27. COPMPUTERIZED INSTRUCTIONAL METHODS:
Computers are powerful tools for these children and should be utilized
as much as possible. The child should be taught compensation and
coping skills. Attention should be given to optimum learning conditions
and alternative avenues for student performance
MULTISENSORY APPROACH:
Techniques designed to help all the senses work together efficiently can
also be used. Specific reading approaches that require a child to hear,
see, say, and do something (multisensory), the Orton-Gillingham
Method.
28. Treatment
STARTS FROM PHONOLOGICAL
AWARENESS;
Fluent readers process text at a number of
levels at the words, the sentence , the
conceptual and the topic level (Munro &
Munro 1991-1994)
Out put is retained in short term working
memory for various duration.
Retaining and processing is performed at

MOST USEFUL METHODS OF READING INSTRUCTION ARE THOSE THAT STIMULATE
THE BRAIN TO AUTOMATICALLY RECOGNIZE THE NUMBER, THE ORDER, AND THE
IDENTITY OF SOUNDS WITHIN WORDS.
34. The brain must not only auditorily perceive, but also visually
represent, sounds, letters, and words. This is known as
Symbol Imagery (SI) and it appears to be a major factor in
the creation of both independent reading fluency, as well as
orthographic (standardized way of using a specific writing
system) spelling.

36. FLUENCY
Ultimately, the goal is to build the student’s auditory
and visual processing systems to the level of
independence so that they may show strong fluency
in reading and writing.
37. COMPREHENSION
The ability to process language is a
prerequisite to learning content.
Specifically the ability to decode,
the ability to retain sight words, the
ability to spell, the ability to
comprehend written and oral
language, and the ability to think
critically are all necessary for
success in content areas.
