Term
|
Definition
-both fluent and non-fluent types of aphasia
-connectionist model
-7 language centres predicting 7 syndromes resulting from damage to a centre or a link |
|
|
Term
| what are the 7 centres in the Wernicke-Lichtheim model |
|
Definition
1)auditory image centre (W's area)
2)motor image centre (B's area)
3)elaboration of 1 and 2
4)motor writing centre
5)visual representation centre
6)primary auditory centre & ears
7)speech organs |
|
|
Term
| the wernike-lichtheim model predicts damage to B's area results in: |
|
Definition
Broca's aphasia
- loss of spontaneous speech writing, repetition, reading aloud and writing |
|
|
Term
| the W-L model predicts damage to W's area results in |
|
Definition
Wernicke's aphasia.
-loss of understanding, spoken and written language
problems with repetition |
|
|
Term
| the W-L model predicts that damage to the connection between W's area and B's area will result in |
|
Definition
Conduction aphasia.
-problems with repetition, reading aloud
-speech and comprehension remain intact |
|
|
Term
| the W-L model predicts damage to the connection between B's area and the elaboration of W and B's area results in |
|
Definition
transcortical motor aphasia
-impairment of speech, conserved comprehension
-conservation of repetition |
|
|
Term
| the W-L model predicts damage to the connection of B's area and speech organs results in |
|
Definition
-loss of speech, repitition and reading aloud
-conserved comprehension and *writing*---main difference from broca's aphasia |
|
|
Term
| the W-L model predicts that damage to the connection of W's area and elaboration of W and B's areas results in |
|
Definition
transcortical sensory aphasia
-loss of comprehension and reading
-conserved speech and writing and repetition |
|
|
Term
| the W-L model predicts that damage to the link between W's area and primary auditory centre & ears results in |
|
Definition
|
|
Term
| Disconnection Model of classification |
|
Definition
-developed by Wernicke and Gesschwind
-same definitions as W-L model but does not include the subcortical aphasias
-83% success rate at predicting the lesion site with CT scan |
|
|
Term
|
Definition
-based on processes rather than syndromes
-Language is the result of complex interaction of a variety of cognitive functions
-language in terms of information processing in a modular view of cognition
(classifications not very different from W-G model) |
|
|
Term
|
Definition
a particular language function is not tied to a specific cortical area.
-each function is processed through modular subcomponents of the system |
|
|
Term
| Jason Brown view of aphasia |
|
Definition
-looks at aphasia from an evolutionary point of view
-based on jacksons work
-higher level brain centres are more rececent in evolutionary terms.
-language has multiple representations at various neural levels
-if a part of the brain controlling a higher level of language is damaged a lower level can be released |
|
|
Term
|
Definition
Jason Brown's theory.
-symptoms are actually always there but are normally hidden by the more readily observable higher level processes.
-aphasic production is the best you can do with the uncompromosed parts of the cognitive system |
