Q

Bilingual and Monolingual
Development are Similar

A
  • Similar milestones as monolinguals:
    – Babbling
    – First word
    – First two-word utterances
  • Both groups have same goal: to become communicators

Q

Are bilinguals confused?
Speaking the Right Language

A
  • Genesee, Boivin & Nicoladis
    1996
  • 1 and 2-year old French- English bilingual infants
  • Videotaped while interacting with monolingual strangers
  • Infants changed their language depending on the language of the stranger
  • However, infants still used words from the other language

Q

Why do young bilinguals mix their
languages?

A
  • Bilingual infants sometimes produce utterances with words from both languages(why?)
    – They don’t know the right word in the other language
    – The people around them mix the languages
  • Children’s amount of mixing is a function of the mixing of their families and communities

Q

Are bilinguals confused?
Two sets of Sounds

A
  • Monolingual babies:
    Discriminate sounds from the world’s languages at 4-6-months
  • By 10-12 months, only discriminate sounds from their native language
  • Bilingual babies: Discriminate sounds from the world’s languages at 4-6 months
  • By 10-12 months, discriminate sounds from BOTH of their native languages

Q

Keeping their languages separate:
Visual Language Discrimination

A

*(Weikum, Vouloumanos, Soto-Faraco,
Navarro, Sebastian-Galles, & Werker,
Science, 2007)

study:
can babies discriminate languague just by looking at face

-habituate babies with people own mother-toung speaking their languague (with no sound) , changed to a new sentence with different languague or control (speaking again the same sentece with the same langue

result:
* Monlinguals at 4 & 6 saw discrimination , but not 8-months

  • only Bilinguals 8 months saw descrimination

Q

How early does bilingualism start:
Bilingual from birth?

A

english monolinguals: mothers spoke only english during pregnancy

tagalog billinguals: mothers spoke english and tagalog regularly during pregnancy (30%-70%)

Tested on language discrimination and preference

Q

Testing learning:
Language preference (results)

A
  • strong suck vs weak one
  • alternaded languague (english vs tagalog)

result= monolingual show a preference for english more then tagalog - sucked more in english

bilingual was a mixed results, didnt show a preference pf one over the other - sometimes sucked more in eglish sometime tagalog (can they tell the difference between tagalog or english)

Q

….. are they really bilingual?

A
  • Two languages? Or
    language confusion?
  • Broad similarity
    gradient….
  • < prenatal exposure to
    each language than
    monolingual has to
    one
  • Can they
    discriminate?

Q

Discrimination

A
  • habituated them in one languague
  • then gave them a semple from another languague
  • control condition: then gave theam a semple from the same languague
  • they could descriminate languague , they just prefer both
17
Q

“Bilingual” newborns

A
  • **Prefer both of their native languages at birth
    **
  • But are able to keep them distinct (discriminate)

– Preference reflects exposure
– Initial discrimination robust, keeps their languages apart

  • Allows neonates to direct attention to native language(s), while maintaining separation
18
Q

Bilingual Word Learning

A

* Vocabulary is smaller in each language, but the total number of conceptual words is at least as big

  • Are equally able to learn new words through word-object associations
  • Do they figure out new word meanings in the same way?
19
Q

Bilinguals know two words for each object. Will they still show Mutual Exclusivity?

A
  • Compared monolingual to
    bilingual toddlers ME Task.
  • Familiar Word Trials: objects they know
  • Disambiguation Trials:: “Where
    is the nil?”

Mutual exclusivity: Because
this child already knows the name of the familiar object on the table, she will
pick up the novel object when the adult asks her to “show me the blicket.”

20
Q

results

A

It looks like bilinguals do NOT show Mututal Exclusivity to the same extent that monolinguals do, and trilinguals do not show it at all!

at chance?
we assume they think that a blicket could be the name of this object in another languague

21
Q

➢ Assumptions & Expectations

A
  • We saw in the previous studies that bilingual infants do not show mutual
    exclusivity to the same degree
  • But do they actually accept a second label for an object?
  • And what do monolingual infants do with that new word? Do they treat it as
    a subcategory term, e.g. a property?
  • Tested this in Kandhadai, P., Hall, D.G., & Werker, J.F. (2017). Dev Sci.

showed them (familarization phase)
pink cat > cat
brow dog > dog
blue dog > zabe

test phase
across category:blue cat and pink dog > zabe
within category:blue dog and brown dog> zabe

monolinguals though zabe was a colour

bilingual though zabe was another name for dog

22
Q

suggesting

A
  • That would suggest it is experience that underlie word learning biases
  • Rather than a constraint or expectation the child brings . . . . . .
23
Q

But – we were wrong!

A

**Both bilinguals and monolinguals can adhere to, or relax mutual exclusivity ……… if they are given information about whether they are hearing one of their known languages **

infants axpect that somoen with a different race speaks another languague :

same experiment from a couple flash cards ago but adding a person from one race and the other race

24
Q

results

A

Monolinguals: with someone from a different race they will understand it can be another name for dogs (it can be the name for another languague)

Monolinguals: with someone from the same race they will not understand it can be another name for dogs but rather a colour (it cant be the name for another languague)

25
Q

A bilingual advantage?

A
  • Adults: Better executive function
    – Bialystok research
  • Do infants show the same?
  • Two studies: 7-months and 12-months
26
Q

Kovacs & Mehler, PNAS 2010

A
  • Bilingual infants aged 7-months
  • Taught to turn head to one side in anticipation of a reward
  • Given a structure, e.g. AAB (le-le-mo)and ABC(le-mo,ve)
  • Shown two white squares
  • Each time it came on, a cute animal appeared in the square on one side

condition 1 :
-white square > ABC = the animal would appear
- white square > AAB = nothing would apear

result = both Bilinguals and Mono linguals were able to understand that

Condition 2:

-white square > ABC = nothing would apear
- white square > AAB = animal would appear

  • Could they learn? And learn to switch?
27
Q

result

A
  • monolinguals could not switch rules in this number of trials like the bilinguals did
