What areas are connected to the vwfa from the ventral route?
Semantic areas; Left anterior temporal lobe along the inferior temporal lobe
1 of 43
What areas are connected to the vwfa from the dorsal route?
Phonological areas; Auditory-phonology processing (Superior medial/posterior temporal regions) and speech-motor processing (L inferior frontal gyrus and speech-motor cortex)
2 of 43
Which characterises surface dyslexia?
Damage to ventral, problems with meaning
3 of 43
Which characterises phonological dyslexia?
Damage to dorsal, problems with sound
4 of 43
Which characterises deep dyslexia?
Damage to both ventral and dorsal, problems with meaning and sound
5 of 43
In the central acquired dyslexias, is perception of written words damaged?
No, the issue lies in semantics and/or phonology
6 of 43
What do patients with surface dyslexia misread?
IRREGULAR words (spelling)
7 of 43
What kind of errors do pps with surface dyslexia make?
Regularisation errors
8 of 43
How would a pp with surface dyslexia pronounce 'leopard'?
leopard --> lee-o-pard
9 of 43
Shown by pps with surface dyslexia, what is the regularisation effect?
Words with regular spellings are read faster and more accurately than irregular spellings
10 of 43
In surface dyslexia, what does the problem with irregular words affect most?
Low frequency words (Frequency x regularity)
11 of 43
What disease is surface dyslexia also seen in?
Semantic dementia
12 of 43
What do the deficits seen in surface dyslexia suggest?
Over-reliance on the dorsal route (GPC rules & conversion) following ventral route damage
13 of 43
What kind of deficits do semantic dementia patients show?
Regularisation errors, particularly for low frequency irregular words
14 of 43
What kind of errors do pps with phonological dyslexia make?
Lexicalisation errors
15 of 43
What is a lexicalisation error?
A non-word being read as a SIMILAR LOOKING real word (fint --> fine, poat --> boat)
16 of 43
When is phonological dyslexia most disabling?
During development as there is not a large sight vocabulary already established
17 of 43
What do the deficits in phonological dyslexia suggest?
A weak dorsal route and a relatively intact ventral route
18 of 43
What do phonological dyslexics also have problems in?
Verbal STM and manipulating phonemes in speech
19 of 43
What do pps with phonological dyslexia read EASIEST?
Familiar words > inverted non-words
20 of 43
Is there a double dissassociation between surface and phonological dyslexia?
Yes
21 of 43
What is the nature of the double dissassociation between phonological dyslexia and surface dyslexia?
Phono = Non words impaired, irregular words preserved. Surface = Nonwords preserved, irregular words impaired
22 of 43
What kind of errors do pps with deep dyslexia make?
Imageability effect
23 of 43
What are pps with deep dyslexia completely unable to do?
Read inverted non-words aloud
24 of 43
Which route is impaired in deep dyslexia?
Both the ventral and dorsal route
25 of 43
What does the right hemisphere hypothesis posit re; deep dyslexia?
Extensive left hemisphere damage means that access to meaning has to occur in right hemi, which is unable to perform GPC conversion or precise semantics
26 of 43
What is often comorbid with deep dyslexia suggesting shared processes between reading and writing?
Deep dysgraphia
27 of 43
What are characteristic of pps with deep dysgraphia?
Inability to spell inverted non-words and semantic errors
28 of 43
How are familiar words processed when we read?
Parallel
29 of 43
Do the number of letters in familiar words have a large effect on reading speed?
No
30 of 43
What kind of process is spelling?
Inherently serial
31 of 43
Which places the most demand on control processes?
Spelling
32 of 43
What is an allograph?
Letter forms
33 of 43
Graphomotor patterns
Movement commands specifying the direction force and duration of a movement
34 of 43
What is the correct order in 'steps towards writing'?
Select grapheme, select allograph, execute graphomotor pattern
35 of 43
Which stage in 'steps towards writing' would a patient with graphemic buffer disorder be impaired in?
Grapheme selection
36 of 43
Which stage in 'steps towards writing' would a patient with alzheimers be impaired in?
Allograph selection
37 of 43
Which stage in 'steps towards writing' would a patient with afferent dysgraphia/parkinsons be impaired in?
Executing graphomotor pattern
38 of 43
What is characteristic of a patient with graphemic buffer disorder?
Problems in retention and control of abstract letter reps leading to errors in all output
39 of 43
What was patient BH (graphemic buffer disorder) impaired at?
Spelling problems in spelling aloud and writing. Problems with non-words
40 of 43
What was the pattern of results in a study of patient BH?
Spelling accuracy decreased as word length increased
41 of 43
What is characteristic of afferent dysgraphia?
Problems in the use of feedback to control graphomotor patterns
42 of 43
Did frequency and AoA have an effect on BHs performance?
Yes, suggesting top down influences
