Bilingualism Flashcards

1
Q

Traditional Story

A

-special group of language users
-learning 2 languages would be confusing
-late bilinguilism
-even highly successful late L2 learners speak with an accent and appear to fail to acquire subtle aspects of the L2 grammar

Q

New Attitude About Bilingualism

A

-there is greater plasticity than previously understood
-bilingualism provides a lens for examining neurocognitive processes
-bilingualism alters the structure and function of the mind

Q

Language Coactivation

A

Joint activation of 2 language systems
-Interactional
-lexical information is activated in target and non-target languages

Q

Word Characteristics

A
  • unique words vs. shared words
    -coactivation increase = word similarity increase
    -E.g. if you’re talking in french and english doesn’t impair = no coactivation

Q

-First fixation duration: length of the 1st time eye fixates on the target - lexical access
-Total fixation duration: length of all eye fixations on target - semantic integration and conflict resolution
-Longer fixation durations linked to greater comprehension difficulty

A

Do bilinguals show effects of parallel activation during reading?

Q

L1 vs L2

A

Speakers can control language coactivation when speaking their L1, but not when speaking their (weaker) L2

Q

Beyond Language Processing

A

Inhibition
-is triggered in the presence of competition
-is proportional to the level of coactivation
-prevents intrusions from the non-used languages

Q

Inhibition

A

Are they semantically?
-Participants were slower to respond to homographs presented along with words related to the Spanish meaning of the homograph
-Bilinguals inhibited the irrelevent homograph meaning requiring now more time to reactivate

Q

Asymmetrical Switching Cost

A

-You need a lot of inhibition of english -> therefor you need more time to reactivate this language

Q

Domain Specific vs Domain General

A

Lifelong management of 2 languages -> enhancements in language control -> enhancements in cognitive control -> changes in the brain

17
Q

Bilingual Advantage?

A

-Flanker Task: the conflict effect was significantly reduced only for bilinguals during the second session
-Spanish-English speaking bilinguals exhibited greater bilateral frontal gray matter volume GMV compared with English speaking monolinguals

18
Q

Monolingual

A

Aging is asociated with an increased reliance on the frontal regions

19
Q

Bilingual

A

The aging brain shows preservation of the posterior regions, and the connectivity

20
Q

Individual Differences

A

-Meta-analyses and systematic reviews found a bilingual/multilingual advantage
-Studies and meta-analyses have emerged questioning the differences

21
Q

Language Experience

A

Your reality
-E.g. I am english, but I am always speaking french at school everyday
-What age
-How much you use it
-Where do you use it

22
Q

Entropy

A

Reflects the linguistic composition, or overall balance of language use, across multiple communicative contexts

23
Q

High Entropy

A

Indicative of high diversity
-Integrated: use multiple languages in a balanced fashion within a context
-Exhibit greater functional connectivity in the brain network associated with language and executive control, and showed higher scores on cognitive control

24
Q

Low Entropy

A

Indicative of low diversity
-Compartmentalized: use a single language in a context
-Predictible
-age- and menopause- related declines in cognitive control, suggesting that females may compensate for decline by virtue of adapting to the externally imposed demands of the language environment

25
Q

Summary on Bilingualism

A
  1. The 2 languages are not seperate
  2. Bilingualism has consequences for both languages
  3. Brain and cognition are plastic -> bilingualism is tool to explore this
  4. Bilinguals differ by virtue of the demands of the context and the experience
