Effects of input quality on ASL vocabulary acquisition in deaf children
The majority of deaf children are at risk for impoverished and/or delayed exposure to language, spoken or signed, because they have limited access to speech sounds and have parents who are not native users of a sign language. Work on the critical period has shown that delayed exposure to a first language has lasting effects on many aspects of development. The goal of this project is to understand how exposure to primarily non-native language input during the critical period affects vocabulary acquisition. We focus on phonological neighborhood density and iconicity—two factors that typically shape sign language vocabulary development (Caselli & Pyers, 2017), but may be uniquely affected by…
