Bilingualism is not a categorical variable: Interaction between language proficiency and usage
Open accessAbstract
Bilingual experience is dynamic and poses a challenge for researchers to develop instruments that capture its relevant dimensions. The present study examined responses from a questionnaire administered to 110 heterogeneous bilingual young adults. These questions concern participants' language use, acquisition history and self-reported proficiency. The questionnaire responses and performances on standardized English proficiency measures were analyzed using factor analysis. In order to retain a realistic representation of bilingual experience, the factors were allowed to correlate with each other in the analysis. Two correlating factors were extracted, representing daily bilingual usage and English proficiency. These two factors were also related to self-rated proficiency in English and non-English language. Results were interpreted as supporting the notion that bilingual experience is composed of multiple related dimensions that will need to be considered in assessments of the consequences of bilingualism.

Dominance is not uniquely equatable with relative proficiency.
“Dominance is not uniquely equatable with relative proficiency (as defined in terms of grammatical and lexical accuracy, speech fluency, etc.), since there are other dimension-based measures of dominance besides proficiency (e.g., object naming speed, lexical diversity, reading speed).”
From Plasticity, Variability and Age in Second Language Acquisition and Bilingualism (2018) · cites this paper as Luk and Bialystok (2013)
The Discussion (page unavailable) treats language dominance as related to both usage and proficiency, supporting the point that it is not simply proficiency. It does not identify object naming speed, lexical diversity, or reading speed as alternative measures of dominance. (LLM, conf=0.78)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
