Q

the wernicke-geschwind model suggests…

A
  1. meaningful speech is created in WA
  2. BA determines the movements needed for vocalisation and sends info to the motor cortex

16
Q

how is syntactic comprehension studied?

A

using priming paradigms and repetition suppression

17
Q

which brain regions underlie syntactic comprehension?

A
  • left inferior frontal gyrus
  • posterior temporal lobe
  • parietal regions, frontal cortex, premotor cortex
  • right inferior frontal gyrus
18
Q

which brain regions underlie language comprehension?

A

similar activity between networks, regardless of production or comprehension

19
Q

what is bilingualism?

A

“an individual who has the mental representation of more than one language for the purpose of speaking and understanding”

20
Q

how is bilingualism measured?

A

functional usage (how much) and verbal proficiency (how well)

21
Q

where can dual language activation be seen?

A

in listening, speaking, and reading tasks

22
Q

why are priming effects present for bilinguals?

A

as words can be semantically and phonologically related

23
Q

what do dual language activation and priming effects suggest?

A

evidence that the brain is able to accommodate the presence of two languages

24
Q

cross-language competition in speech planning is resolved by…

A
  1. develop skills in attended to the critical information that signals language status
  2. learn to inhibit irrelevant information once activated
25
benefits of managing two languages
- promote cognitive benefits - executive function and frontal lobe development - delays the onset of dementia symptoms
26
why are there bilingual advantages in the stroop test and simon task?
reduced incongruency effects can be explained by experience in resolving competition across the two languages
27
what tasks are bilinguals poorer at?
word retrieval and fluency
28
brain activity in bilingualism
- activated a lesser portion of the ACC - greater grey matter volume in inferior parietal lobe, which correlated with L2 proficiency and age of acquisition
29
unimodal bilinguals
two spoken languages
30
linguistic output channel of unimodal bilinguals
vocal articulation
31
bimodal bilinguals
a signed and a spoken language
32
linguistic output channel of bimodal bilinguals
vocal and manual articulation
33
bimodal bilinguals and ASL
produce on average 4 ASL signs when talking to a non-signer
34
what was concluded about bilingual bimodalism?
inhibition was less necessary when languages do not compete for the same articulators
35
what is there no evidence of for bimodal bilinguals?
that they are better at inhibition tasks
