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)
