Q
What does the propositional definition of aphasia say?
A
an affected person can’t formulate goal directed utterances, can’t convey intent
1
Q
When was the majority of Paul Broca’s work done?
A
1860s
2
Q
What do the cognitive theorists of aphasia believe?
A
there is some intellectual problems with aphasia
3
Q
What do localizationist theorists say about aphasia?
A
affected individuals have difficulty naming and disassociation between a label and a concept
4
Q
What does the concrete-abstract definition of aphasia say?
A
abstract language is more propositional and that is the deficit in aphasia
5
Q
What does the uni-dimensional theory of aphasia say?
A
aphasia is a single disorder, you don’t differentiate between different types of aphasia
- all modalities of language are impaired to some extent
- should find the relative strengths within the language system to rebuild the weaknesses
6
Q
What does the multi-dimensional theory of aphasia say?
A
- there is differential diagnosis
- different types of aphasia based on the site of lesion and the clients behaviors
7
Q
What does the microgenetic theory of aphasia say?
A
lesions in certain areas lead to specific deficits

8
Q
What does the thought process theory of aphasia say?
A
there is an impairment in semantic expression due to a deficit in thought processes
9
Q
What does the psycholinguistic theory of aphasia say?
A
separates aspects of language into cognitive (what we know about the world), linguistic (form and content), and communicative (pragmatics)
-aphasia causes a problem with the content, form, use, and knowledge about the world
10
Q
What is the definition for aphasia used in class?
A
an acquired communication disorder caused by brain damage characterized by an impairment of language modalities (not a sensory, intellectual or psychological deficit)

graphemic input lexicon has to go through what so you can comprehend a word?
semantic representation system
107
explain the lexical semantic route
looks at the features of words
- processed through letter representation system
- then perceived graphemes go through the graphemic input lexicon
- then the graphemic input lexicon goes through a semantic representation system so you can comprehend
- if you read aloud you then assign a grapheme to a phoneme
