Dyslexia, Phonological and Phonemic Awareness, and Decoding Flashcards
the SLP’s role in dyslexia diagnosis
SLP’s knowledge of normal and disordered language acquisition, and their clinical experience in developing individualized programs for children and adolescents, prepare them to assume a variety or roles related to the development of reading and writing
appropriate roles and responsibilities for SLPs include but are not limited to
- preventing written language problems by fostering language acquisition and mergent literacy
- identifying children at risk for reading and writing problems
- assessing reading and writing
- providing intervention and documenting outcomes for reading and writing
- assuming other roles, such as providing assistance to general education teachers, parents, and students
- advocating for effective literacy practices
- advancing the knowledge base
speech and reading development
- early speech delays
- delays in phonological development
- delays in phonological and phonemic awareness
- difficulty linking sounds to letters
things to know about dyslexia
- lifelong, neurobiological, language-based learning disability
- genetic, inheritable
- requires expert, intensive evidence-based treatment
- one of the diagnoses that could qualify school-age child as having a specific learning disability
DSM-V dyslexia
alternative term used to refer to a pattern of learning difficulties characterized by problems with accurate or fluent word cognition, poor decoding, and poor spelling abilities
most recent research in reading
- one specific, “core” area of deficit (phonological processing), doesn’t effectively account for reading difficulties
- measures of phonological processing over- or under-identify dyslexia in > 30% of kids
- subgroup of dyslexia: solid decoding and word reading, but weak ORF
- distinct subtypes are likely, but more research is needed
dyslexia, what it is
- under- and over-activation
- use less efficient pathways than skilled readers
- affects how speech sounds are stored in the brain + how those sounds are retrieved
- impacts ability to identify and manipulate phonemes
- accuracy and speech of l/s correspondence, word, and sentence reading
- working memory
dyslexia, what it isn’t
- a problem with vision: letter reversals, reading letters backwards
- related to IQ
- related to motivation
- related to instruction
the big 5 of dyslexia
- phonemic awarness
- phonics
- fluency
- vocabulary
- comprehension
phonological awareness (PA)
- word awareness
- onset-rime awareness
- syllable awareness
- phoneme awareness
- sound structure of spoken words
- identify, manipulate linguistic units: big to small, initial, final, medial
phonological awareness development
- units of spoken language
- word -> syllable -> onset/rime -> phoneme
- from less working memory to more working memory (categorize, blend, isolate, segment, delete/add/substitute, reverse)
decoding
- once children become aware of the segmental nature of spoken language, they can link those sounds to letters (70%-80% of children are able to map sounds onto letters without much difficulty)
- the relationship between the letters of the language (graphemes) and the sounds
encoding vs. decoding
- encoding: speech -> print
- decoding: print -> speech
decoding development: consonants
- letter name knowledge
- single consonants
- consonant blends
- consonant digraphs and trigraphs
- silent letter patterns
- orthographic patterns
decoding development: vowels
- single letters for vowels
- long vowel sounds
- vowel combinations that represent a single sound
- diphthongs
- r-controlled vowels
