Vocabulary Outcomes for 5-Year-Old Children Who Are Deaf or Hard of Hearing: Impact of Age at Enrollment in Specialized Early Intervention.

The aims of this study were to examine vocabulary scores of 5-year-old children who are deaf or hard of hearing (DHH), as well as the impact of early enrollment in specialized intervention on vocabulary outcomes. Receptive and expressive vocabulary scores were analyzed for 342 five-year-old children who are DHH enrolled in specialized listening and spoken language intervention programs. Regression analyses were utilized to examine the effects of age at enrollment on vocabulary outcomes.

Language Environments and Spoken Language Development of Children With Hearing Loss.

This study examined the relationships between adult language input and child language production in regard to the quantity and diversity of spoken language, as well as children's knowledge of basic concepts and vocabulary. The quantity and diversity of language provided by teachers and parents were related to children's language output and knowledge. Language ENvironment Analysis technology audio-recorded the language environments of 26 preschool children with hearing loss over 2 days.

The Impact of Language Input on Deaf and Hard of Hearing Preschool Children Who Use Listening and Spoken Language.

The researchers investigated the effects of adult language input on the quantity of language, vocabulary development, and understanding of basic concepts of deaf and hard of hearing (DHH) children who used listening and spoken language. Using audio recording and Language ENvironment Analysis (LENA) software, the study involved 30 preschool DHH children who used spoken language as their communication modality and 11 typically hearing same-age peers. The children's language and the language spoken to them during all waking hours over a 2-day period (16 hours per day) were recorded and analyzed quantitatively and were compared to the children's performance on the Boehm Test of Basic Concepts and the Peabody Picture Vocabulary Test.
