Week Six - Reading Flashcards
how many people use an alphabetic writing system?
> 75%
3 types of writing systems?
- Logographic: unique graphic symbol for each word (eg chinese)
- Syllabic: unique graphic symbol for each syllable (eg japanese)
- Alphabetic: unique graphic symbol for each phoneme (eg italian, english)
Three conditions for true alphabet?
- each phoneme must be represented
- 1:1 correspondence between graphemes and phonemes
- 20-30 graphemes (allows to memorise)
Deep orthographies?
Don’t have consistent GPCs (>1 way to write each phoneme and say each grapheme)
- english
- french
types of words?
regular: graphemes map regularly onto phonemes (eg beef, stove)
irregular: graphemes not pronounced onto phonemes (eg steak, pint, love)
lexical hermits: no close neighbours
pseudowords: novel words that can be pronounced in a normal way
non-words; cannot be pronounced ie not real words
Dual-route model of reading 2 routes and their steps?
- direct access route (for irregular and familiar) - written word - lexicon - pronounce
- indirect route (unfamiliar) - written word - GPC rules - pronounce
Phonological mediation?
Strong view: visual word recognition requires sounding-out of word
Weak view: sound can influence recognition
Three-way interaction between a words…
frequency, imageability and spelling consistency
Stages of Ehri’s model of reading development?
letter knowledge
semi-phonetic
alphabetic
consolidated alphabetic
Stages of Frith’s model of reading development
logographic
alphabetic
orthographic
difficulties with early speech results in
social ostracism and poor self-esteem
spoken language is… written language is…
primary… secondary…
Reading age is often..
> 2 SD below chronological age despite average IQ
Common factor of dyslexia
can’t read unfamiliar words
Possible explanations of dyslexia? 3
Magnocellular deficit: impaired visual pathway resulting in deficits in eye control, reading
Temporal auditory processing deficit hypothesis: when auditory stimuli is presented at rapid frequencies
Phonological deficit hypothesis: deficits in representing/using phonological information (eg spelling-to-sound)
People with dyslexia have poor skills in?
phoneme segmentation, phoneme blending, phoneme manipulation, identification of rhymes
What can improve the process of reading and spelling?
Training in sound categorisation
Each encounter with a new word =
opportunity to apply and extend knowledge
Mechanisms of progress for reading/spelling?
rapid build up of lexicon - more familiar words - more rapid/automatic reading
