Q

Anatomy of Expressive Aphasia

A

left inferior frontal cortex; anterior to the primary motor cortex (facial movement); premotor cortex

17
Q

Premotor Cortex (expressive aphasia)

A

consistent with sequencing deficits (speech –> motor processes); difficulty with phonemes into words and words into sentences

18
Q

Fluent speech

A

relatively normal rate, rhythm, and intonation

19
Q

Neologisms

A

make up words

20
Q

Symptoms of Receptive Aphasia

A

fluent speech; semantic paraphasia; neologisms; poor comprehension; poor reception

21
Q

Anatomy of Receptive Aphasia

A

posterior perisylvian region; planum temporale; conceptual link between auditory representations of words with meanings

22
Q

Conduction Aphasia

A

normal speech comprehension & production (primary areas intact); isolated difficulty with repetition; phonemic paraphasia; difficulty naming (objects); arcuate fasciculus damaged

23
Q

What is the arcuate fasciculus involved with?

A

conduction aphasia

24
Q

Difficulties with the classical connectionist model of language?

A

lesions don’t precisely match expected patterns; variability in definition of lesions; aphasias not clearly defined clinically

25
Q

Mental lexicon

A

the interface that links representations of word form or sound with other types of knowledge

26
Q

how many words does a normal speaker have in their lexicon?

A

50,000-100,000

27
Q

how many words can a normal speaker recognize?

A

3 per second

28
Q

Semantic Network

A

word meanings characterized by complex connections

29
Q

how is the semantic network organized?

A

based on meanings of words, with similar words having stronger connections than dissimilar words

30
Q

Spreading activation

A

activation of a conceptual node will lead to activation of similar concepts nearby

31
Q

Behavioral evidence of semantic network

A

semantic priming studies: first memory of a word pair presented, second word presented is either fake, real unrelated, or real related word. Results: fastest to respond to real related words bc no network exists for fake words

32
Q

Biological evidence of semantic network

A

category specific naming deficits; Lesions

33
Q

Semantic Network: category specific naming deficits

A

damaging neural networks; H. Damasio examined naming deficits in faces, animals, tools–people have isolated deficits, combined deficits, and deficits in all three, but no combined deficits in faces and tools

34
Q

Face deficits

A

left temporal pole

35
Q

animal deficits

A

inferior temporal lobe

36
Q

tool deficits

A

posterior temporal lobe

37
Q

Gow

A

argued there should be networks for speaking if there are for words; found longer voice onset time for words with phonological competitors compared to noncompetitor words; Dorsal basis for lexicon (angular gyrus, superior longitudinal fasciculus, premotor cortex)
