Aims and objectives:
We compare the performance of 600 bilingual children with and without language impairment relative to their level of current English input and output (EIO). Children were tested in both Spanish and English on measures of morphosyntax and semantics. Our aim was to examine whether children’s language performance was differentially affected by the level of EIO and/or language ability.
Methodology:
Participants were drawn from three different studies of bilingual language impairment where children between the ages of 5 and 10 years were tested using a standardized test of morphosyntax and semantics in both languages. Standard scores were compared for each language in each domain.
Data and analysis:
Multivariate regression was used to compare main effects of ability (children with typical language development versus children with language impairment) and interactions with EIO. This analysis was followed by a comparison of EIO across the four language measures.
Findings/conclusions:
There were main effects of language impairment status and EIO. There were ability differences in slope for two measures (English semantics and Spanish morphosyntax), where children with language impairment had a flatter slope as related to EIO compared to children with typical development. For Spanish semantics and English morphosyntax, slopes relative to EIO were similar, although children with language impairment scored lower than those with typical development.
Originality:
We observed how children with and without language impairment performed on semantics and morphosyntax tasks relative to their EIO.
Implications:
The similar slopes across language measures of children with and without language impairment suggest that there is no disadvantage to divided input by ability. Where there were differences by ability, children with language impairment showed a flatter slope relative to their typically developing peers, suggesting that bilingual children with primary language impairment (PLI) may be somewhat advantaged relative to more monolingual children with PLI.
