Quality and Quantity of Language Input and Its Relation to the Language Outcomes of Preschool Children With Hearing Loss Who Use Listening and Spoken Language

Arora, Sonia

This study sought to examine the relationships between the adult language input, as measured by quantity and quality, and the child’s language production in regards to quantity and quality, as well as their knowledge of basic concepts and vocabulary. LENA technology was used to audio-record the language environments of 26 preschool children with hearing loss over two days (weekday and weekend). This technology recorded up to 16 hours and analyzed the quantitative data associated with the adult word count (AWC), conversational turn count (CTC), and child vocalization count (CVC). Furthermore, one- hour meal times (30 minutes for the weekday/snack time and 30 minutes for the weekend/dinner time) was transcribed and coded for quality components of language defined as lexical diversity, syntactical complexity and clausal complexity. Additionally, the children were assessed on their knowledge of basic concepts through the Boehm Test of Basic Concepts (BTBC-3) and the Peabody Picture Vocabulary Test (PPVT-4).
Results indicated that there was a relationship between the adult language input and the child language production, but only in regards to quantity of language. More specifically, the CTC during each day was related to the CVC for each day; in other words, the more interactions adults and children had during the day, the more likely the child vocalized. Interestingly, the statistical analysis revealed that quality of adult language input was not significantly related to the child language variables. However, significant differences between the teachers and caregivers were reported in regards to the quality of adult language input. These results suggest that the language input provided by adults in different environments (school versus home) is considerably different and warrants further investigation as how the potential influence on language outcomes of children with hearing loss.
