I am sure that you've heard the old adage that reading is
fundamental, but have you taken time to contemplate how reliant
we are on reading?
Just imagine trying to get healthcare for
a loved one if you couldn't read.
There are tons of forms,
then you have to read up on the medical condition.
If you get a prescription, you have to read what it is,
when to take it, and how much.
This is kind of important stuff.
And given that this is a big deal, you're probably not
surprised that reading is linked to health outcomes.
Reading is truly a life skill that most of us
take for granted.
I mean, if you think about it, why shouldn't most of us?
We learned how to read in school, and
it's just something we picked up, it's something we could do.
But this is not the reality for
the people who struggle with reading due to dyslexia.
Reading ability falls along a continuum.
Some individuals are great, superstar readers,
while others are just average.
But then there's people who are below average
to well below average.
Individuals with dyslexia fall towards the lower end of this
continuum.
Dyslexia is a brain-based type of learning disability that
specifically impairs a person's ability to read.
Dyslexia is characterized by difficulties with accurate and
fluent word recognition and by poor spelling and
decoding abilities.
Decoding is our ability to sound out words to read them.
Dyslexia is extremely prevalent and
is the most common learning disability.
The ability for all children
to read is influenced by multiple factors
that interact with one another to bring about reading success.
One of these factors is motivation.
With that said, dyslexia is not the result of a child being lazy
or not trying hard enough.
Children with dyslexia can work just as hard and
even harder than the other kids in their class and
still struggle to read.
All of this effort will achieve little if these children are not
provided with the appropriate instruction to address
their needs.
Environmental factors also impact reading achievement, and
solid, core classroom reading instruction is critical for
the success of all students.
But dyslexia is not the result of poor core reading
instruction.
Don't get me wrong, our schools can be improved, but individuals
with dyslexia can be found in even the best of schools.
During the early grades, the majority of children respond to
high-quality, direct reading instruction.
But some kids do not respond to this high-quality instruction,
and parents and teachers alike are left wondering why these
kids are not learning to read.
For many of these kids, the reason could be dyslexia.
But there is hope for these individuals.
Children and adults with dyslexia can learn to read when
provided with appropriate instruction that addresses their
educational needs.
Individuals with dyslexia require direct, intensive,
systematic, cumulative reading instruction.
But why don't they respond to less intensive quality
instruction like many other students?
The answer is in part due to neurobiological differences
observed in individuals with dyslexia.
One of the risk factors is a family history of dyslexia, and
it is well documented that dyslexia runs in families and
has a genetic component.
Our genes provide the blueprints for our brain, and
dyslexia is a brain-based learning difference.
My research and the research of many others provides a better
understanding of this brain basis.
Reading is supported by areas of the brain that allow us to
produce and understand language.
These language areas work with the visual centers and
learning circuits of the brain to support reading development.
This distributed network of brain regions allows a person to
understand written language.
Individuals with dyslexia show differences in areas of this
distributed network.
Differences can be seen in functional brain scans taken
while individuals perform reading tasks.
Differences are also seen on structural brain scans.
And the wiring that connects the areas of the brain involved in
reading differ between individuals with dyslexia and
their typically developing peers.
Another part of the answer to the question,
what causes dyslexia, can be found in how we process language
at a cognitive level in support of reading.
But before we consider the cognitive components
of dyslexia,
we first need to consider the different components of reading.
The ultimate goal of reading is to comprehend text.
If comprehension does not occur, then a person has not read.
But we can't comprehend a text if we do not have the skills
needed to identify the words on the page.
And we use our ability to understand spoken language to
comprehend written language.
Our ability to understand spoken language is supported by many
skills, more than I can capture in a single figure.
But to highlight a few, children need a wide vocabulary,
background knowledge of the topic being discussed.
They need to be aware of the meaning units within words.
And they need to know how words are put together to form
meaningful expressions.
Children also need to be able to read print fluently.
When reading aloud,
they should be able to read quickly with expression.
Fluent reading requires an ability to efficiently and
accurately identify individual words.
The identification of written words is supported by an ability
to sound out individual words.
This is the skill of decoding, and
to identify words by sight, sight word reading.
Sounding out words to identify them is supported by knowing our
letters, their formation, and
the sounds that go with them in the language.
Sounding out words is also supported by the ability to
hear the internal structure of words and
isolate the individual sound units that make up words.
For example,
there are three sound units in the word βhuff,β /h/ /u/ /f/
Proficient readers are highly accurate in word reading and
the skills that support reading words.
Proficient readers are also highly efficient and
automatic in word reading.
And just as phonological awareness supports
the development of accurate word reading that is needed to allow
students to develop proficient word reading skills,
Rapid Automatized Naming supports the speed by which
a person can read words.
Pulling a word from memory or
effortlessly decoding a word is supported by our ability to
efficiently go from print to sound,
to go from seeing something to being able to access its name.
So now let's turn back to the cognitive basis of dyslexia for
many individuals.
Remember, dyslexia is characterized
by underachievement in accurate and/or fluent word reading.
Individuals with dyslexia also often struggle with
sounding out and reading words.
But why is it that a child can have such a selective deficit in
areas of written language?
The reading deficits of individuals with dyslexia often
stem from a problem with processing the sound structure
of language.
These aspects of language are phonological awareness and
Rapid Automatized Naming.
When these components are deficient, we commonly observe
corresponding deficits in reading accuracy and fluency.
Deficits in word reading ability give rise to an issue with
comprehending text and learning new vocabulary.
We often forget that most of the vocabulary that
we learn comes from reading.
It isn't possible to directly teach all the vocabulary
necessary to support language development and listening and
reading comprehension.
So students who struggle with word-level reading skills often
lag behind their peers in learning new vocabulary.
Notice that I've not mentioned that dyslexia is a generalized
learning disability.
Well, because it's not.
I've not said that these kids are dumb or lazy,
because that's not true.
And they're not throwaway kids or adults.
These individuals have a very selective deficit that limits
their ability to learn how to read.
And they need more intensive, direct,
systematic reading instruction than others.
But when they receive this instruction,
they will learn how to read.
Here at MTSU in the
Tennessee Center for Dyslexia
we are striving to help raise awareness about
the success that these children can achieve.
We want to help parents, educators, and
policymakers become aware of what these needs are, so
that collectively, we can work together to make sure that
we strive to meet these needs.
So look forward to more future videos such as this to help
raise awareness about other aspects of dyslexia.
