The Neuropsychology of Reading and Written
Language Disorders: A Framework for Effective Interventions
2
PRESENTATION OF GOALS
1. Discuss the role of school neuropsychology, within an RtI
framework, as a more viable means to both assess and
remediate learning disorders in children.
2. Explore the neuropsychological underpinnings of reading and written language disorders by examining the underlying neural circuitry involved in processing this type of academic information.
3. Introduce a brain-based educational model of diagnosingreading and written language disorders by classifying each into four subtypes, with specific remediation strategies linked to each subtype.
4. Introduce the 90 minute LD evaluation as a more comprehensive means to assess eight core cognitive constructs associated with learning disorders in children.
3
Currently, approximately 6.7 million children receive
special education services under IDEA, which
corresponds to approximately 9 percent of all children
aged 3-21 in public education.
Approximately 40 percent of those children receiving services are classified as being “learning disabled”
due primarily to reading and/or written language
deficiencies.
Clearly, literacy is the single most important educational attribute paving the road for not only school success,
but perhaps for successful life endeavors as well.
Kavale and Forness (2000) revealed nearly 50% of students classified as having a learning disability do not
demonstrate a significant discrepancy between
aptitude and achievement due in part to the statistical
impreciseness of this method.

Traditional Problems with Special
Education Service Delivery Model
A deliberate separation of regular education from special education.
Undocumented benefit of special education for children with high incidence disabilities.
A disconnect between testing for eligibility purposes versus testing for what
interventions work best.
A reactive model not geared toward early intervention services.
IEP’s that rarely emphasize the “I”.
Inconsistent qualification decisions since there
is no universal agreement on what
constitutes a significant discrepancy.
5
1. There is no universal agreement on what the
discrepancy should be, or developmental guidelines
for discrepancy expectations.
2. It remains unclear as to which IQ score should be
used to establish a discrepancy.
3. A discrepancy model of learning disabilities precludes
early identification and creates a “wait and fail” policy.
4. A discrepancy model of reading assumes that IQ is the
best predictor of successful reading.
What is the relationship between IQ and reading?
Discrepancies only represent unexpected underachievement!!

IDEA REATHORIZATION - signed into law by President
Bush in December, 2004.
States may opt out of using the discrepancy model to identify learning disabilities, and replace with
RTI.
Gives school districts flexibility to craft policy whereby students who do not respond to
scientifically based reading program can be
eligible for SPED.
Requires districts with disproportionate number of minorities in SPED to consider eliminating the use
of IQ tests.

(1) Universal Screening - for all students a
minimum of three times per year.
(2) Baseline Data - using curriculum-based
measurement as primary data gathering means.
(3) Measurable Terms - define problem areas
numerically.
(4) Accountability Plan – monitor fidelity of
selected intervention.
(5) Progress Monitoring – how, where, and when
intervention results will be measured and
recorded.
(6) Data Based Decision Making – ongoing analysis
of data to drive future intervention decisions.

RtI strengths: allows for earlier intervention.
non-categorical.
excellent for progress monitoring.
utilizes data to make decisions.
systemic deployment of interventions.
RtI weaknesses: is not sufficient to identify a learning disability
(National Joint Commission on Learning Disabilities, June 2005)
RtI is incapable of differential diagnosis and offers
little in identifying other emotional conditions or attention
factors hindering learning (Reynolds, 2008).
Run the risk of delaying assessment and denying a
student eligibility for services (OSEP memo, 2010).
RtI models often promote standard protocol
interventions and assume a “one size fits all” approach to
remediation (Feifer & Della Toffalo, 2007).
Evidence based interventions require evidence based assessments!!
RtI Strengths and Limitations
12
School Neuropsychological Assessment
Reports based upon a brain-behavioral paradigm which attempts to describe how a
child learns and processes information.
Focus on why the child has not been
successful in school as opposed to IQ
scores.
Less emphasis on whether or not the
student qualifies for special education
services.
Examine the cognitive and emotional strengths and weaknesses of the child and
link to specific educational strategies and
interventions.

Forest Grove School District case reached the Supreme Court in June, 2009. The local school psychologist
evaluated a child and concluded there was no
disability present.
The parents sought a private assessment that was more comprehensive and examined multiple cognitive
constructs. There was evidence of a disability. The Due
Process Hearing Officer concluded that the school
district failed to provide FAPE and that the school district
is liable for private school services.
Supreme court justice John Paul Stevens agreed with the Due Process Hearing Officer because the school had
overlooked a disability because they had not completed
a comprehensive evaluation in all areas of the suspected
disability. Cost of tuition…$5200 per month.
Do you agree?

Competing Neuropsychological Models1. Cattell-Horn-Carroll (CHC) model emphasizes
cross battery assessment examining broad and
narrow abilities (Dawn Flanagan).
2. Discrepancy/consistency approach utilizing the
PASS model of information processing
(Jack Naglieri).
3. Cognitive Hypothesis Testing (CHT) model links
assessment to intervention using a demands
analysis (Brad Hale & Cathy Fiorello).
4. School Neuropsychological Conceptual model
of information processing (Dan Miller).
5. 90 Minute Learning Disorders model teasing
out subtypes of each disorder (Steven Feifer).
*Let us begin our discussion on how reading
is represented in our brain.
15
1. In all word languages studied to date, children with
developmental reading disorders (dyslexia) primarily
have difficulties in both recognizing and manipulating
phonological units at all linguistic levels (Goswami,
2007).
2. English speaking children tend to develop phonemic
processing more slowly than children in more
phonologically consistent languages such as Spanish
or Italian (Goswami, 2007). Still, children in all
languages initially become aware of larger acoustical
units within the words themselves such as syllable,
onset, and rhyme.

The English language includes over 1,100 ways of representing 44 sounds (phonemes) using a series of
different letter combinations (Uhry & Clark, 2005). By
contrast, in Italian there is no such ambiguity as just 33
graphemes are sufficient to represent the 25 phonemes.
Therefore, 25% of words are phonologically irregular (i.e. “debt”, “yacht”, “onion”, etc..) or have one spelling but
multiple meanings (i.e. “tear”, “bass”, “wind”, etc..)
The six types of syllables that compose English words must be directly taught as orthographic representations.
a) Closed syllables (just one vowel…”cat”)
b) Open syllables (ends in long vowel…”baby”)
c) Vowel-Consonant E Syllables (silent e elongates vowel...”make”)
d) Vowel-Team Syllables (two vowels make one sound…”caution”)e) R-Controlled Syllables (vowel followed by “r”changes sound…”hurt”)
f) Consonant-le Syllables (end of word ending in “le”…..”turtle”)
How Complex is English????
17
3. Specific neuroimaging techniques have
demonstrated that phonological processing is
a by-product of the functional integrity of the
temporal-parietal junctures in the left
hemisphere of the brain ….supramarginal
gyrus (Pugh et al., 2000, McCandliss & Noble,
2003; Shaywitz, 2004; Sandak et al., 2004).

4. According to the National Reading Panel(2000), the
most effective method of teaching a phonologically
challenging language such as English is through a
direct and explicit model of phonological
development.

(1) The younger the child, the better the outcome.
(2) The “at-risk” child responds best to small group
instruction (3:1), with phonological awareness
training being combined with explicit phonics.
(3) Highly trained teachers achieve the best results.
(4) Frequency of instruction (4-5 days per week) was
more effective than sporadic instruction (2 days per
week).
(5) Gains were maintained in most children at long-term
follow up.
(6) The following characteristics were associated with
poor outcome:
a) attention or behavior concerns
b) low socioeconomic status
c) poor verbal skills
d) poor rapid naming skills

(1) Readers at this age respond to explicit phonological
instruction, though gains were not as strong as with
younger children.
(2) These readers were less responsive to explicit
phonological instruction, though did better in one-to-
one or small group instruction.
(3) More intensive work for a longer duration required.
(4) Spelling and fluency did not improve much, though
some improvement with reading comprehension.
(5) Computer instruction served as an effective aid, but
was not effective by itself.
(6) The following characteristics were associated with
poor outcome:

Neural Circuitry of Reading Disorders
Nonimpaired readers activate primarily
posterior portions of left hemisphere.
Impaired readers under-activate posterior
regions and activate primarily frontal
areas.

Question: Can brain chemistry actually become altered
as a result of practice and effective interventions???
London cab drivers showed direct correlation between number of years on the job and hippocampal
volume (Maguire et al., 2000)
Bilingual individuals have more gray matter in the left angular gyrus than monolingual students, no matter
when the second language was acquired (Green et al.,
2007)
There is a correlation between the size of Heschl’s gyrus and the amount of time practicing an instrument
(Schneider et al., 2002)
Dyslexic students fail to activate brain regions associated with phonological processing and
automaticity (Shaywitz & Shaywitz, 2005).
Our Adaptive Brain
23
Our Adaptive Brain
Researchers (Hoeft, et al., 2010) were able to predict with 90% accuracy which teens could improve their reading based upon
neural activation in the right inferior frontal gyrus of the brain.
This was more accurate than any standardized reading measure
including the Woodcock Reading Mastery Test.
The strongest gains were in reading comprehension rather than phonological awareness. The right longitudinal fasciculus,
a pathway connecting front and back speech zones, tended to
show greater activation. (Proceedings of the National Academy of Science).
24
Four Subtypes of Reading Disorders
(1) Dysphonetic Dyslexia – difficulty sounding
out words in a phonological manner.
(2) Surface Dyslexia – difficulty with the rapid
and automatic recognition of words in print.
(3) Mixed Dyslexia – multiple reading deficits
characterized by impaired phonological and orthographic
processing skills. Most severe form of dyslexia.
(4) Comprehension Deficits – mechanical
side of reading is fine but difficulty persists deriving
meaning from print.

4 REMEDIATION STRATEGIES FOR
MIXED DYSLEXIA
(1) Balanced Literacy - An eclectic and approach capitalizing
on the particular strengths of the child. Consider using a
multi-sensory type of Orton-Gillingham program, coupled
with a fluency model such as Read Naturally, and the
computerized models of Read 180.
(2) Top Down Strategies – Often atypical development
mapping individual sounds to the visual word form
association areas (Temple, 2002; Shaywitz, et al, 2003; Noble
& McCandliss, 2005).
(3) Socioeconomic Status - According to Noble and
McCandliss (2005), socioeconomic status (SES) is a very
strong predictor of reading skills due primarily to the home
literacy environment. Therefore, schools need to provide
more reading opportunities.
(4) Motivation and Confidence –Great Leaps, Read Naturally,
and Neurological Impress tend to give immediate feedback.
30
1. Content Affinity - attitude and interest toward
specific material.
2. Working Memory - the ability to temporarily
suspend information while simultaneously
learning new information. The amount of
memory needed to execute a cognitive task.
3. Executive Functioning - the ability to self-
monitor performance and organize
information on a given problem solving task.
4. Language Foundation – most children enter
kindergarten with 3000 – 5000 words, though
graduate from high school with 60,000 words
(Pinker, 1994).

Measuring Written Language
The National Center for Educational Statistics
administered writing samples to 276,000 students
in grades 4, 8, and 12 (2003).
Narrative Writing – involves the production of stories or personal essays to capture a reader’s imagination.
Can include responses to photographs, poems, and
cartoons.
Informative Writing – communicates information to the reader to convey a message, instruction, or an idea.
Includes reports, reviews, and letters.
Persuasive Writing – influence the reader to take action to bring about change. Should include reasons,
examples, comparisons. Examples included writing to a
friend, newspaper editor, or refute an argument in a
debate.
Scored as Basic, Proficient, or Advanced.

42
Why the disconcerting trend?
Most students rely on writing,
either e-mail, text messages, word
processing, or other computerized
technology to communicate.
Downward extension of our
curriculum whereby reading and
written language are skills
emphasized in kindergarten.
Most state assessments require written language responses, short answers, and brief constructed
responses even in subjects such as mathematics.
Therefore, most school curriculums readjusted to
emphasize state testing requirements.

The Cost of Poor Writing Skills
U.S. corporations spend an
estimated $3.1 billion annually
to remediate their employees’
writing skills (National Commission
on Writing, 2005).
State governments spend approximately
$221 million annually to do the same
(National Commission on Writing, 2005).
A 2005 ACT (American College Testing)
report indicated almost one-third of high
school students planning to attend
college do not meet the readiness
standards for college composition
courses.
44
Curriculum-Based Measurement: Writing
6 Components to Assess Writing:
(1) Fluency: measure the number of words written and spelled correctly in a time period.
(2) Grammar: informally assess from passage.
(3) Vocabulary: assess variety by dividingnumber of different words by total numberof words.
(4) Sentence Structure: summarize sentences as being incomplete, simple, compound, complex, run-on, or fragmented.
(5) Conventions: percent of words spelled correctly, proportion of errors per 100 words, correct writing sequence.
(6) Content: develop analytic rating scale.

1. Dysphonetic dysgraphia - the hallmark feature of this disorder is an inability to spell by sound, thus rendering an over-reliance on the visual features of words.
2. Surface dysgraphia -this disorder is characterized
by a breakdown in the orthographic representation of
words. Miscues made primarily on phonologically
irregular words.
3. Mixed Dysgraphia - this disorder is characterized by a combination of both phonological errors and orthographical errors depicting faulty arrangement of letters and words.
4. Executive Dysgraphia - an inability to master the implicit rules for grammar which dictate how words and phrases can be combined. Deficits in working memory and executive functioning frontal lobe skills.

1) There should be data documenting that a student’s
RATE of learning is substantially slower than grade
level peers.
2) There should be data documenting that a student
has not responded to evidenced-based
interventions over a protracted period of time.
3) There should be data from standardized testing
indicating the presence of a psychological
processing deficit associated with the academic
skill in question. This may include measures of
phonological or orthographic processing skills,
language skills, working memory skills, executive
functioning skills, and rapid naming and retrieval
skills.
4) There should be data ruling out environmental,
medical, emotional, and cultural factors.
