Lexical iconicity--signs or words that resemble their meaning--is overrepresented in children's early vocabularies. Embodied theories of language acquisition predict that symbols are more learnable when they are grounded in a child's firsthand experiences. As such, pantomimic iconic signs, which use the signer's body to represent a body, might be…

With the increasing prevalence of autism spectrum disorder (ASD), clinicians and schools are receiving a larger number of assessment referrals for eligibility or diagnostic clarification of ASD in children who are deaf and hard of hearing (D/HH). Meeting this increasing demand is often difficult given not all assessment professionals seek…

Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

In my dissertation, I examine four notation systems used to represent hand configurations in child acquisition of signed languages. Linguists have long recognized the descriptive limitations of Stokoe notation, currently the most commonly used system for phonetic or phonological transcription, but continue using it because of its widespread…

This study investigates the relationship between theory of mind (ToM) skills in deaf children and input from their hearing mothers. Twenty-two hearing mothers and their deaf children (ages 4-10 years) participated in tasks designed to elicit talk about the mind. The mothers' mental state talk was compared with that of 26 mothers with hearing…

Discoveries about the acquisition of American Sign Language (ASL) by deaf children are reviewed. Current research shows that ASL has developed as a fully autonomous language with complex organizational properties not derived from spoken language. Like spoken languages, ASL exhibits formal structuring at two levels and similar organizational…

Examines why bilingual education for deaf children is the best option, suggesting ways to ensure that deaf students receive the necessary American Sign Language (ASL) models in their early education. Notes that the best way to achieve success in ASL, and consequently in English, is to require that preschool teachers of deaf students be native…

Considers the cross-linguistic findings concerning the early development of formal, arbitrary, grammatical systems in normal hearing and deaf children and in children with congenital brain abnormalities. Evidence is reviewed that shows an early acquisition of grammatical forms. (Author/JL)

It is unclear how children develop the ability to learn words incidentally (i.e., without direct instruction or numerous exposures). This investigation examined the early achievement of this skill by longitudinally tracking the expressive vocabulary and incidental word-learning capacities of a hearing child of Deaf adults who was natively learning…

Discusses the modifications in the direction of simplified and more linear language (American Sign Language) used by deaf mothers with their deaf children. (EKN)

Reviews work on the acquisition of complex verbs in American Sign Language (ASL), delineating three lines of research showing how children acquire ASL and discussing possible reasons for the particular fashion in which different children (native learners, non-native learners, and native learners with parents who are non-native learners) acquire…

In examining the issue of why children do so well at language learning despite limited skill and experience, two possible explanations are addressed: one suggests that children learn language well exactly because they are limited, and the other proposes that children are extremely adept at language learning, perhaps more so than adults. Research…

Examination of American Sign Language--produced by a deaf child acquiring the language from deaf parents, and videotaped at age 13, 15, 18, and 21 months--shows conformity to many of the phonological rules operative for all languages. (Author/CFM)

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

Reports research on the communicative behavior of a hearing child whose parents communicated with him, from birth, in both signs and words. The child's expressive ability accelerated in both modalities and this is possibly attributable to the addition of the signed component. (PJM)
