How language exposure affects vocabulary learning in deaf children
Effects of input quality on ASL vocabulary acquisition in deaf children
['FUNDING_R01'] · BOSTON UNIVERSITY (CHARLES RIVER CAMPUS) · NIH-10829387
This study looks at how the way hearing parents, who are learning American Sign Language, communicate with their deaf children affects the kids' ability to learn new words, helping us find better ways to support their language development.

What this research studies
This research investigates how the quality of language input, particularly from non-native sign language users, impacts vocabulary acquisition in deaf children. It focuses on the critical period of language development, examining factors like phonological neighborhood density and iconicity in sign language. The study involves observing interactions between deaf children and their hearing parents, who are learning American Sign Language (ASL) as a second language, to understand how these dynamics influence language learning. By analyzing these interactions, the research aims to identify patterns that could inform better language teaching strategies for deaf children.
Who could benefit from this research
Good fit: Ideal candidates for this research are deaf children, particularly those with hearing parents who are learning ASL.
Not a fit: Patients who are already fluent in ASL or have native ASL users as parents may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to improved language acquisition strategies for deaf children, enhancing their communication skills and overall development.
How similar studies have performed: Previous research has shown that early and rich language exposure is crucial for language development, suggesting that this approach could yield significant insights.
