Deaf and hard of hearing babies need early, consistent access to a fully accessible language for healthy thinking, social, and academic growth. Use this reading list to ground that message in evidence. It gathers research showing that restricting access to ASL puts children at risk for language deprivation (missing out on full language in the early years, which can have lasting effects), while early ASL proficiency and Bilingual exposure support literacy and flexible thinking. The studies span developmental psychology, linguistics, and neuroscience. Use it to support early language planning and conversations with families and colleagues.
