Abstract
We investigated home language (Spanish) maintenance in Spanish- and English-speaking bilingual children with normal hearing (NH) and their peers with hearing loss (HL) who used cochlear implants (CIs) at two time points about 7 months apart. Twenty-two bilingual children (11 with NH and 11 with CIs) between the ages of 4;6 and 7;11 participated in the study, who were matched as closely as possible on chronological age, time elapsed between the first and the second sample, gender, and age of exposure to their languages across groups. We compared group performance on the Preschool Language Scales – 5th edition (PLS-5) and the Word Intelligibility Picture Identification at each time point as well as home language maintenance calculated based on item responses on the PLS-5. Our results indicated differences on all measures at both time points between the performance of children with NH and their peers with HL who used CIs in that the former group outperformed the latter. We also found that bilingual children with NH maintained their home language at a higher level than their peers with HL who used CIs. Further, the data also showed that despite the group differences, both groups displayed maintenance of their home language and that individual variability was more prevalent in the CI group. We conclude that home language maintenance is not only possible, but it should be encouraged for both bilingual children with NH and their peers with HL who used CIs.
