Etiology

Phonological ProcessingPhonological Processing

Phonology

• Phoneme: – Building block of words

S ll t it f h– Smallest unit of speech– There are 40 - 52 phonemes in the English language – Are put together to form wordsAre put together to form words

• Words can be broken down into their elemental sounds allowing us to decipher words

• Deficits in phonology strongly correlate with reading problems

Phonologic System

• Processing and production of speech sounds

• Earliest language system to develop• It is natural does not have to be taught• It is natural – does not have to be taught• It is the foundation of language

Phonological Processing Deficits

Fluency

• The ability to read text– Quickly– Accurately– With good understanding

• The hallmark of a good reader• Is the bridge between decoding and g g

comprehension• It is acquired word-by-wordq y

Dyslexia Etiology

• Language problem specific to the Phonologic Module– Functional part of the brain where

• Sounds of language (phonemes) are put together to form wordstogether to form words

• Words are broken down into their elemental sounds (phonemes)

• Discriminates words from noise– Learning to read is not a natural biological

What to look for

Early Signs of Dyslexia

• By age of onset:– Delay in speakingDelay in speaking– Difficulty in pronunciation– Insensitivity to rhymeInsensitivity to rhyme– Poor word retrieval or word finding– Naming the letters and their sounds– Naming the letters and their sounds

• Infants and toddlers– Delay in speakingDelay in speaking

• First word by 1 year• Phrases by 18 - 24 months• Parents may ascribe it to family history

– Speech delay and dyslexia are familial

• Preschool years– Difficulty in pronunciationDifficulty in pronunciation

• No “baby talk” by 5 or 6 years of age• Typical problems:

– What to listen for» Omission of initial sounds: lephant for elephant,

chi-en for chicken» Inverting sounds: aminal for animal

• Preschool years– Insensitivity to rhymeInsensitivity to rhyme

• Unable to recite nursery rhymes– Children that remember nursery rhymes tend to be

d dgood readers

• Unable to differentiate between similar and different words

– Can not focus on parts of the words» What rhymes with: food, talk

• Poor word retrieval or word finding– Talking around a word (circumlocution)Talking around a word (circumlocution)– Uses words like “stuff” or “things”

• Naming the letters and their sounds– Before entering Kindergarten

• Knows the names of upper and lower case letters

– Before entering 1st grade• Knows the names and sounds of letters• Knows the names and sounds of letters• Alphabetic principle

– Sequence of letters = number and sequence of soundsM t h b i i d f d• Matches beginning sounds of words

• Pronounces beginning sounds of words• Counts phonemes in small words

• Typical development– 4 – 6 y/o aware that words come apart4 6 y/o aware that words come apart– 6 y/o 70% can count phonemes in small words

• Early signs of dyslexia• Early signs of dyslexia– After 1 year of reading instruction (end of 1st

grade) can’t separate sounds of spoken wordgrade) can t separate sounds of spoken word

Common Signs of Dyslexia

• Problems with:– Phoneme segmentationPhoneme segmentation– Phoneme deletion– Specific word retrieval (i e tornado forSpecific word retrieval (i.e. tornado for

volcano, prostitute for prosecute)– Rapid word retrievalRapid word retrieval

What to do about it.

Research Based Reading Instruction• Essential Components

– Phonemic awareness• Recognize, remember and manipulate individual soundsg p

– Phonics and word recognition• Sound – symbol relationship, word meaning

– Reading Fluency• Read with sufficient speed an accuracy to support

comprehension – Vocabulary development

• Individual word meanings• Individual word meanings– Reading comprehension

• Verbal reasoning, background knowledge, comprehension strategiesg

Reading Instruction

• Other components– Basic writing skillsBasic writing skills

• Compose English with accuracy, fluency and clarity of expression

– Comprehending and using language• The ability to listen and understand the

i f h t i imeaning of what someone is saying

Effective Reading Instruction• Explicit

– Clearly and directly explained not left to discovery• Systematic

– The speech sounds, spelling patterns, sentence structures, text genre and language conventions

• CumulativeC ti l i kill b ild th– Continual review one skill builds on another

• Multisensory• Sequential and Incremental

M bl t– Manageable steps• Data driven

– Emphasis, speed of instruction and support are determined by student's progressstudent s progress

• Establish a treatment program that recognizes ADHD as a chronic condition

• Specify appropriate target outcomes to guide management• Prescribe stimulant medication and/or behavior therapy to• Prescribe stimulant medication and/or behavior therapy to

improve target outcomes in children with ADHD• If the treatment program has not met target outcomes,

evaluate:– Original diagnosis– Use of all appropriate treatments– Adherence to the treatment plan

Presence of coexisting conditions– Presence of coexisting conditions• Using information from parents, teachers, and the child,

follow-up to evaluate target outcomes and adverse effects
