Bilingual children's comprehension of code-switching at an uninformative adjective

Area of Science:

• Psycholinguistics
• Developmental Psychology
• Bilingualism

Background:

• Bilingual children frequently encounter code-switching, mixing words from two languages in sentences.
• Previous research indicates code-switched nouns cause processing costs and reduced comprehension in young bilinguals.
• However, the impact of code-switches at other grammatical points remains under-investigated.

Purpose of the Study:

• To examine if code-switches preceding a target noun, specifically at the determiner-adjective phrase, incur processing costs for bilingual children.
• To compare the comprehension of code-switched sentences with single-language sentences in young bilinguals.

Main Methods:

• Thirty bilingual children aged 37-48 months participated.
• Participants processed sentences containing code-switches (e.g., 'le bon duck') versus single-language sentences ('the good duck').
• Object identification accuracy was measured for both sentence types.

Main Results:

• Bilingual children accurately identified target objects regardless of whether the sentence contained a code-switch or not.
• This finding contrasts with prior research showing processing difficulties with code-switched nouns.
• No significant processing costs were observed for code-switches at the determiner-adjective level.

Conclusions:

• Code-switching at the determiner-adjective phrase does not impede object identification in young bilingual children.
• The functional linguistic information conveyed by code-switches may facilitate, rather than hinder, sentence processing in bilingual development.
• Future research should explore the role of specific linguistic contexts in bilingual sentence processing.
