RESUMEN
PURPOSE: Children who are deaf and hard of hearing (DHH) have documented deficits with complex syntax and vocabulary knowledge. Mental state verbs (MSVs) are necessary for some kinds of complex syntax use and communicate abstract concepts needed for academic language. The purpose of this study was to examine the frequency, diversity, and syntactic context of MSV use in children who are DHH compared to children with typical hearing (CTH). METHOD: Seventy-three preschool children (23 with cochlear implants, 22 with hearing aids, and 28 with typical hearing) completed a structured language sample as part of a larger assessment battery. Samples were analyzed and compared across groups for use of MSVs, diversity in MSV use, and syntactical context for MSVs. RESULTS: Children who are DHH used significantly fewer MSV in complex syntax, a smaller diversity of MSV, and significantly fewer MSV in obligatory contexts compared to CTH. Results for the cochlear implants and hearing aid groups were not significantly different from one another despite differing levels of hearing loss. CONCLUSION: Children who are DHH demonstrate significant differences in the rate, diversity, and complexity of MSV use compared to peers with typical hearing.
