Signed languages offer a more accessible input for deaf children, but because the vast majority are born to hearing parents who do not sign, their early exposure to sign language is limited. Deaf children as a whole are therefore at high risk of language…

We adapted the semantic fluency task into British Sign Language (BSL). In Study 1, we present data from twenty-two deaf signers aged four to fifteen. We show that the same "cognitive signatures" that characterize this task in spoken languages are also present in deaf children, for example, the semantic clustering of responses. In Study…

A total of 1,018 signs in one deaf child's naturalistic interaction with her deaf mother, between the ages of 19 and 24 months were analyzed. This study summarizes regular modification processes in the phonology of the child sign's handshape, location, movement, and prosody. First, changes to signs were explained by the notion of phonological…
