What was the earlier belief of bilingualism?
It leads to confusion and is linked to “inferior intelligence”
Really was a test of different socioeconomic status
What was the result of 1960 Montreal’s bilingual test?
Bilingual children have more cognitive plasticity and did better on cognitive tests
T/F - Bilingualism is unique
False - 50-70% of world is bilingual
What is independent activation?
One language will be activated while the other is not
What is parallel activation?
Both languages are activated
What is the correct activation for bilingualism?
Parallel activation
What are cognates?
Form and meaning is the same in two languages
E.g., hotel in English and hotel in French
What are false friends?
Forms are the same, but meanings are different
What happens if there is a cognate in the languages you speak and you hear it?
Cognate facilitation effect: you respond faster
What happens if you know two languages and you don’t hear a cognate?
No difference in response time
How are eye-tracking used as a measurement?
Fixation vs. saccade - longer fixation linked to greater comprehension difficulty
What was the results of the eye-tracking experiment?
Both languages are coactivated
- Cognates = shorter fixations (facilitation)
- False friends = longer fixations (interference)
What is the inhibitory control model?
Supervisory attentional system -> activates inhibitory system to suppress the language not needed
What does level of inhibition of a language equal to?
Level of competition
- More competition => higher level of inhibition
How are languages scales?
When one is up, the other is lowered
How does cognitive overload impact the language scale?
We have limited resources -> can lead to errors
What happens if words are semantically related?
More time to respond
What is asymmetrical switching cost?
What is the explanation for asymmetrical switching cost?
It is easier to inhibit non-native language than native language
How does bilingualism result in changes in the brain?
Due to enhancements in language control -> enhancements in general control -> change
What is the bilingual advantage hypothesis?
Bilingual young adults demonstrate superior performance on inhibitory control tests
- Phenomenon is extremely controversial
How is “Cooking pasta in La Paz” by Thomas H. Bak used as a comparison?
Boiling point is 100C everywhere except Bolivia due to altitude (88C)
- Mixed results are likely genuine and can co-exist
- Not easy to characterize bilinguals
How does grey/white matter look like in bilinguals?
More than monolinguals
After how much time does white matter change in bilinguals?
Very quickly to small exposure to language - but can also easily be reversed
