Week 9 (The Literate Brain) Flashcards
(16 cards)
When was writing first used
(4000-6000 years ago)
When was the alphabet first used
1800 BC
Eye movement study
-Studies show we don’t fixate on every letter
-Influenced by reading direction, length of word, predictability.
Logographic language
One symbol = One word
Syllabic language
One symbol = syllable
What can be useful to study reading
Brain imaging
What are the main regions activated by reading
Left inferior frontal gyrus
Left temporoparietal cortex
Left infer-temporal cortex
How could the left infero-temporal cortex be linked to reading
Orthography
-Direct lexical access?
How could the left temporoparietal cortex be linked to reading
Phonological assembly + semantics
How could the left inferior frontal gyrus be linked to reading
Phonological and semantic access
Word processing: visual lexicon
We read words in many forms, we extract or generalise the typical features
Serial Vs Parallel Processing
Visual word recognition not strongly affected by word length (parallel processing)
-May involve processing letter clusters rather than individual letters
Occipitotemporal gyrus
Responds to:
-Words more than false-fonts or consonant strings
-Upper and lower case equally
-Real words more than non-words sounding the same
-Orthographic identity of the word
Visual word form area
Central Dyslexia and Dyspraxia
Problems with word forms or meanings
-Damage to ventral or dorsal language routes
