The Complexity of the Spanish Subjunctive in Bilingual Children with SLI

摘要

This study investigated the use of the Spanish subjunctive in bilingual children with and without specific language impairments (SLI). Using an elicited production task, we examined: (1) the potential of the subjunctive as a grammatical marker of SLI in Spanish-English bilingual children, (2) the extent to which degree of bilingualism affects performance, and (3) the specific patterns of errors across groups. The participants in this study were 16 children with SLI and 16 typically developing children (TD) matched on age, English language proficiency, and mother’s education level. Bilingual children were selected based on their English proficiency and were classified either as Spanish-dominant children with intermediate English proficiency (asymmetrical bilinguals, AsyBi), or near-balanced bilinguals (BalBi). A completion task elicited the subjunctive in complement, purpose and temporal clauses. Results suggest that (1) level of bilingual proficiency, language clinical status, and age predicted of the accurate production of the subjunctive, (2) temporal clauses might have a better potential to discriminate between TD children and children with SLI in bilingual settings, and (3) tense underspecification errors were common in children with SLI. This study provides general support for grammatically targeted approaches to assessment in bilingual populations, and for theoretical approaches that link SLI to tense deficits.
