Speakers monitor their speech output by listening to their own voice. However, signers do not look directly at their hands and cannot see their own face. We investigated the importance of a visual perceptual loop for sign language monitoring by examining whether changes in visual input alter sign production. Deaf signers produced American Sign…

We tested the hypothesis that syntactic and narrative comprehension of a natural sign language can serve as the linguistic basis for skilled reading. Thirty-one adults who were deaf from birth and used American Sign Language (ASL) were classified as skilled or less skilled readers using an eighth-grade criterion. Proficiency with ASL syntax, and…

Describes a study in which two nonspeech communication systems were evaluated with respect to their efficacy for use with profoundly retarded nonspeech children. Results show that 53 profoundly retarded children who have failed to acquire expressive linguistic skills can succeed with some alternative nonspeech symbol systems, especially with…

Examines the acquisition of conditional sentences in American Sign Language (which entail the use of both manual signs and grammaticized nonmanual facial expressions) by deaf children. The results indicate that children first acquire manual conditional signs before they employ obligatory grammaticized facial expressions, and also acquire manual…

Analysis of hearing-impaired adolescents' signed and written sentences expressing simple locative state relations found noun reversal and pragmatic focus errors in 7 percent of signed and 15 percent of written responses. Most errors were produced by profoundly hearing-impaired signers attending public day school. (Author/CB)

Examination of the spoken English development of a hearing child whose deaf parents used American Sign Language (ASL) identified a consistent but not extensive ASL influence on simultaneity of expression, undifferentiated versus differentiated features, bound versus free morpheme mechanisms, and word order.

Testing of deaf readers' comprehension of relative clause structures in written English, signed English, and American Sign Language suggests that a specific syntactic disability does not differentiate good from poor deaf readers, but rather a processing deficit may underlie poor readers' comprehension difficulties.

Reports research which investigated the effects of microcomputer technology on the acquisition of writing and reading skills in 32 deaf children. The learning mechanism underlying the instructional system used is responsive, interactional and exploratory, reflective of the way most children acquire a first language. (SED)

Examined longitudinally the handshape aspect of American Sign Language signs in young children of deaf parents. Parents demonstrated on videotape how the children formed the different signs. Findings reveal that four basic handshapes predominated in early sign production, and that the part of the hand involved in contacting a sign's location often…

Examines the effect of adult recasting in sign language on the acquisition of specific syntactic-semantic structures by deaf children aged 9 to 76 months. Results indicated that recasting triggered the acquisition of new syntactic-semantic structures in American Sign Language and English, evident in the spontaneous production of previously…

Focuses on the acquisition of negation in American Sign Language (ASL) and the developmental relationship between the communicative and grammatical (or linguistic) headshakes for negation in deaf children acquiring ASL. Results indicate that the systems for communication and language are differentially mediated. (35 references) (Author/CK)

Using a video sign-monitoring task in American Sign Language, this study investigated the effects of late exposure to a primary language on adult linguistic processing. Native signers were sensitive to errors in both verb agreement and aspect; early and late signers were only sensitive to errors in aspect morphology. Late exposure was found to…
