Exploring Language Exposure's Relationship to Neurobiological Linguistic Outcomes in d/Deaf Infants
The advantages of early exposure to language in order to firmly establish a first language during early childhood have long been documented for d/Deaf children, as this is critical in future language development and literacy skill. This pilot study seeks to describe D/deaf children's language experience and exposure, to explore how these factors may contribute to successful language development. The proposed study will recruit 5 d/Deaf babies of both hearing and Deaf parents, ages 6-36 months to participate in a battery of language measures. Infant language exposure in American Sign Language (ASL) and spoken English will be reported utilizing the Language Exposure Assessment Tool (LEAT) and parents will also complete the Language Experience and Proficiency Questionnaire (LEAP-Q) to report their own language abilities. Language measures will include: a language sample, the Battelle Developmental Inventory-2nd Ed, parent report of infant language ability using the MacArthur-Bates Communicative Development Inventory- ASL (ASL-CDI), and a vowel contrast speech perception event-related potential (ERP) task. Due to small sample size, results from all measures will be analyzed as components of a linguistic profile of each participant.
