Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Reduced input in one language is related to that language's weaker syntactic development. → Bernardini 2004
Evidence¶
Bernardini 2004¶
Bernardini, P., & Schlyter, S. (2004). Growing syntactic structure and code-mixing in the weaker language: The Ivy Hypothesis. Bilingualism: Language and Cognition, 7(1), 49-69. https://doi.org/10.1017/S1366728904001270

The authors relate documented differences in input quantity (daycare language, parental language use, contact with grandparents) to the measured syntactic asymmetry between languages. They state "The amount of input in the two languages is clearly related to language dominance."
"The amount of input in the two languages is clearly related to language dominance: the reduced input in French for Paul, L´eo and Alex, in Swedish for Alice, and in Italian for Lukas can be related to their syntactic development in their Weaker Language, according to the measures presented below."
Discussion¶
Learner Variables¶
- Syntax — outcome: instruction changes it
Related Claims¶
- Code-mixing decreases and ceases as the weaker language syntactic structure develops to CP level — related
- MLU differs by about one word between the stronger and weaker language throughout development — related
- Vocabulary is poorer in the weaker language, with roughly one-third the word types of the stronger language — related
- Children with uneven bilingual development prefer the stronger language and mix sentence-internally mainly in weaker-language interactions — related
- The Ivy Hypothesis differs from the Dominant Language Hypothesis and Bilingual Bootstrapping Hypothesis in developmental scope and hierarchical prediction — related
- Mixed utterances reflect the same amount of syntactic structure as monolingual utterances in the weaker language at the same recording — related
