Re-examination of data on noun-verb pair comprehension and production in Australian and American Sign Language confirm the existence of formationally related noun-verb pairs in Auslan in which the verb displays a single movement and the noun displays a repeated movement. Overall, the derivational process appears closely linked to an iconic base…

Notes that three papers and commentary (in this issue) emphasized importance of including data on manual modality when studying language development and its relationship to other domains. Discusses advantages of using robustness analysis rather than precursor relations to study domain relations. Suggests alternative theoretical context to which…

Introduces three papers (published in this issue) contrasting the development of gestures and sign language with spoken language in order to specify the nature of language plasticity (susceptibility to change) and robustness (invariance). Focuses on question of whether these are parallel systems or an integrated system with two forms of…

The ability to attribute false beliefs by 155 deaf children (ages 5 and 8) grouped by communication mode and parental hearing status was compared to that of 39 hearing children (ages 4 to 6). Effective representational abilities were demonstrated by deaf children of deaf parents, whereas those with hearing parents appeared delayed, with…

Deaf children with signing parents, nonnative signing deaf children, children from a hearing impaired unit, oral deaf children, and hearing controls were tested on theory of Mind (ToM) tasks and a British sign language receptive language test. Language ability correlated positively and significantly with ToM ability. Age underpinned the…

Studies of American Sign language including functional magnetic resonance imaging of deaf signers confirms the importance of left hemisphere structures in signed language, but also the contributions of right hemisphere regions to sign language processing. A case study involving cortical stimulation mapping in a deaf signer provides evidence for…

The fundamental link between language and action is the rationale behind the design of four interactive video programs intended to teach deaf children verb tenses, literacy, and reading comprehension, and to teach hearing parents of deaf children to use British Sign Language. The four interactive video programs are described. (MBR)

This study investigated the ability of two groups of profoundly deaf students (N=40 and ages 8, 11, 14, and 17), using either oral or signed communication, to employ pragmatic skills required for effective face-to-face interactions. Notable differences in pragmatic skills were found between the groups and between deaf and normal hearing students.…

Sign language production of 14 low-functioning students (ages 9 to 20) with autistic disorder were examined. The location aspect of signs was produced more accurately by subjects than either the handshape or movement aspects. Wide individual differences were observed. Sign vocabulary size and accuracy was correlated with performance on two…

Study examined trends in the signing skills of parents of deaf children. Of 50 deaf individuals, 73 percent of deaf children (ages 4-18) reported their parents knew some sign language, whereas older individuals (ages 41-76) reported only 22 percent of their parents knew some sign language. Younger offspring rated their parents' signing skills…

This report, arising from a 1991 meeting, provides an update to two of the six areas covered in the 1989 long-term plan of the National Institute on Deafness and Other Communication Disorders. These include: (1) balance and the vestibular system; and (2) language and language impairments. For each area, the state of the art is reviewed, recent…
