Deaf children, home language environments, and reciprocal-contingent family interactions.

Engaged communication between mother and a child in their early developmental stages is one of the predictors of children's development of higher-order thinking skills. For deaf children, this engaged communication between mother and child hinges on the home language environment (HLE) being fully accessible to the child. This research uses agogical phenomenology in exploring the lived experiences of participants' HLE where sign language is used, with particular focus on the opportunities for extended discourse. Data were collected via semistructured interviews with the deaf children and their parents and observations in the HLEs of five signing families with at least one deaf child in the southwestern United States. The aim of this study was to document and provide insights into how language use in deaf children's HLE can impact their knowledge development; these insights uncovered the essence of reciprocal and contingent family interactions as a central aspect of the deaf child's HLE. It is hoped that the qualitative phenomenological findings will frame subsequent quantitative investigations of the variability in language access to home language components.
