The "unskilled and unaware effect" refers to the finding that individuals who are less knowledgeable or less skilled in a domain are relatively less able to evaluate their level of skill or effectively utilise feedback relative to individuals who are more skilled. Studies finding deaf students less accurate than hearing students in…

Successful face-to-face communication involves multiple channels, notably hand gestures in addition to speech for spoken language, and mouth patterns in addition to manual signs for sign language. In four experiments, we assess the extent to which comprehenders of British Sign Language (BSL) and English rely, respectively, on cues from the hands…

Families with deaf parents and hearing children often demonstrate bimodal bilingualism, using both a signed and a spoken language. This study uses an audience design framework to analyze the home language use of two bimodal bilingual families in the United States. The school-age children in these families appeared to design their utterances for…

Background: Deafness has an adverse impact on children's ability to acquire spoken languages. 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…

Bilinguals who are fluent in American Sign Language (ASL) and English often produce "code-blends"--simultaneously articulating a sign and a word while conversing with other ASL-English bilinguals. To investigate the cognitive mechanisms underlying code-blend processing, we compared picture-naming times (Experiment 1) and semantic categorization…

Two groups (N=65 each) of congenitally deaf teenagers divided according to hearing/deaf parents were assessed for three measures of communicative fluency and two measures of English grammar/structure. High correlations were found between reading and the English grammar measures. Fluency in American Sign Language was not correlated with reading for…

Investigates the differences in the use of certain verbs of movement and location between native ASL learners and children of hearing parents exposed to signing outside the home. Describes the children's use of phonology, morphology, and syntax in repeating target utterances. Relates results to interaction of language acquisition and motor…

Describes a study that found, contrary to previous reports, that a strong, symmetrical release from proactive interference (PI) is the normal outcome for switches between American Sign Language (ASL) signs and English words and with switches between Manual and English alphabet characters. Subjects were college students enrolled in their first ASL…
