Bilingualism and receptive vocabulary achievement: Could sociocultural context make a difference?

The purpose of this study was to investigate receptive vocabulary achievement among French–English bilinguals in Canada. Standardized test scores of receptive vocabulary were measured in both languages from preschool, early-elementary, and late-elementary French–English bilingual children, and French–English bilingual adults. Mean vocabulary scores across all bilingual age groups were statistically equivalent to or above the standard mean in French and English with the exception of the early-elementary bilinguals who scored below the standard mean on the English vocabulary assessment. Mean vocabulary scores of the preschool and adult bilingual groups were not significantly different from those of their monolingual peers in either language. However, early-elementary and late-elementary bilingual children scored significantly lower than monolinguals on the English vocabulary assessment. The positive sociocultural context for French–English bilingualism in Canada as well as language input changes in school are discussed as underlying reasons for these findings.
