13 important questions on Bilingualism in SLP: state of the science - Bilingualism in childhood - Sequential bilingual speech and language acquisition

What is sequential bilingualism speech?

Synoniem = successive bilingual language acquisition

The acquisition of an L2 during childhood after exposure to the first language (L1) has begun.
In general: children begin to acquire a second language at the onset of schooling.

Does L1 support in L2 acquisition?

Yes

How does L1 support in L2 aqcuisition?

=> with the Linguistic interdependence hypothesis:

L2 skills depend on L1 skills and proficiency (vaardigheden):
-  L1 partially "equips" L2
- L1 skills and metalinguistic knowledge can be "used" when learning L2.
- L1 and L2 contain surface features
- Common underlying proficiencies accros L1/L2   = CUP

Give the 4 stages in early successive L2 development

Stage 1: Home language use
Stage 2: Silent period or nonverbal period
Stage 3: Telegrahip and formulaic speech
Stage 4: Productive language use

What is the developmental trajectory by secquential bilingual child?

See picture
Stages

Explain the phonological devolopment by secquential bilingual child

- CLT (cross linguistic transfer) can accelerate / decelarate acquisition rate -> when L1 sound = or isn't the same as L2 sounds.
- These phonological differences / similarities between L1 / L2 also influences acquisition path => type of phonological errors
- Phonological transfer is temporary!

Explain the grammatical development by secquential bilingual child

- CLT can accelerate / decelarate acquisition rate -> when L1 word order = or isnt't the same as L2 words. L1 argument placement L2 argument placement.
- These grammatical differences / similarities between L1 / L2 also influences acquisition path => type of grammatical errors
- L2 children will relatively easy learn morpho syntacic information!

Explain the lexical development by secquential bilingual child

- Variation among BI and differences compared to MO
- Vocabulary distributed accross languages: fewer words per language than MO but similar vocabulary growth over time (MO + BI)
- Caution for overdiagnosis when assessing vocabulary in this group!

What are the inter-individual differences?

- Child internal factors
- AoA L2, language aptitude (bekwaamheid)
- Child external factors
- Quantity / quality home language input, educational environment, SES..

What are the typical characteristics simultaneous and sequential acquisition?

- Language dominance
- Code- Mixing
- Cross linguistic transfer CLT
- BICS and CALP
- Addive and subtractive bilingualism

Explain language dominance + influencing factors?

Definitions: difference in language use : language dominance from SLP vieuwpoint

Influencing factors:
- Quantity language input
- Quality language input
- Sensitivity majority language
- Parents attitude

Explain code-mixing, 2 types + SLP viewpoint?

= alternating between 2 or more languages within a single phrase, sentence of discourse.

Intra utterance: within the same utterance bv my shoes are bleu
Inter utterance: same stretch of conversation bv how old I am? Moi, j'ai 10 ans.

SLP viewpoint:
- Typical pattern of bilingual language use
- Communicative resource (bv filling lexical gap)
- Mostly adapted to the grammatical rules of both languages
- Shaped by social/family norms
- Reflection of the child's cultural identity
- Children should not be discouraged from code-mixing
- Code-mixing is not an indication of confusion, language disorder, poor vocabulary

Explain additive and subtractive bilingualism

Additive refers to the occurence in which the first language continues to be developed and the first culture to be valued while the second language is added.

Subractive refers to the occurence in wich the second language is added at the expense of the first language and culture, which than diminishes (or disappears) as a consequence.

Reason? Unequal of equal importance of different languages.

Consequence
? Less accurate school language development, emotional problems.

It is important to avoid subtractive bilingualism. Bv immigrant second language learners, given the lack of support for their cultural values and languages.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
