Aphasia Auditory Comprehension Presentation

Question 1

Tessier et al (2007) patient presentation

Answer 1

difficulties for verbal comprehension - not hearing some syllables , asking people to repeat.
music is only noise
voice recognition - difficult to recognise voices.
Environmental sound - I hear the noise but cannot recognise the phone ring.

Question 2

Behaviours that alert you for comprehension difficulties

Answer 2

Problems following conversation 
Odd responses to questions 
Can hear but not repeat/understand 
Difficulties following instructions 
Stop listening to TV/Radio 
Fluent aphasia - CSP :)., meaning :( 
Output errors - empty speech, neologisms, jargon.

Question 3

Auditory Agnosia (not aphasia)

Answer 3

Problems with auditory processing of all sorts - not just language. Damage above APA. Associated with bilateral damage to temporal lobes. May have difficulties discrimination between speech and non-speech sounds.

Question 4

Damage to auditory phonological analysis/Word Sound Deafness

Answer 4

Word sound Deafness
Profound auditory comprehension disorder
Repetition very difficulty - RW better than NW
Shorter words harder to understand - more neighbours
Speech can be error free as can writing, reading aloud and writing to dictation can be normal.
Often co-occurs with auditory agnosia.
Lip reading usually helps.

Question 5

Damage to phonological input lexicon/ Word form deafness

Answer 5

Word from deafness
Poor on lexical decision making -RW/NW discrimination
Heavy reliance on context to aid comprehension
May comprehend longer words better than shorter ones - length effect.
Higher frequency words may be easier - frequency effect.
May be poor at repetition.
A pure deficit here is rare.

Question 6

Deficits in accessing the semantic system - Word Meaning Deafness

Answer 6

Word Meaning Deafness
Rare
Poor comprehension
Abstract words may be more difficult, longer words may be easier.
Good lexical decision making (if pure form) but unable to access meaning.
Can repeat RW/NW.
Can access meaning via reading/writing - so write ey words as strategy.

Question 7

Comprehension deficit can be caused by damage to semantic system

Answer 7

All modalities affected: reading, writing, spoken and auditory.
Imageability effects
Semantic effects
Will have to compare all modalities.
