Abstract
BACKGROUND: In spite of recent gains in language development made by children with hearing loss (HL) as a result of improved auditory prostheses and earlier starts to intervention, these children continue to struggle academically at higher grade levels. We hypothesize that one reason for these incongruent outcomes for language and academics may be that the language demands of school escalate as grade level increases, outstripping the language abilities of children with HL. We tested that hypothesis by examining a higher level skill that is essential for success with academic language, the ability to access multiple interpretations for a sentence. METHOD: 122 children participated at the end of middle school: 56 with normal hearing (NH), 15 with moderate HL who used hearing aids (HAs), and 51 with severe-to-profound HL who used cochlear implants (CIs). Children's abilities to provide more than one interpretation for an ambiguous sentence were assessed. These sentences were ambiguous due either to words having multiple meanings or to syntactic structure that could evoke more than one interpretation. Potential predictors of those abilities were evaluated, including expressive vocabulary, comprehension of syntactic structures, grammaticality judgments, forward digit span, and several audiologic factors. RESULTS: Children with NH performed best, children with CIs performed poorest, and children with HAs performed intermediately to those groups. Children in all groups achieved higher scores on the multiple meanings than on the syntactic structure items. The variables that were associated with performance varied across groups. Audiologic factors did not explain any variability in performance on the ambiguous sentences task for children with HL. CONCLUSIONS: The kind of linguistic flexibility needed to consider more than one interpretation for sentences lacking immediate, real-world context is essential to processing academic language. Children with HL - especially those with severe-to-profound HL who required CIs - showed deficits in this skill, which could contribute to their ongoing academic struggles. Continued language support is needed for these children to allow them to acquire the higher level language skills necessary for success through all of their years in school.
