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…

The present paper summarizes three experiments that investigate the effects of age of acquisition on first-language (L1) acquisition in relation to second-language (L2) outcome. The experiments use the unique acquisition situations of childhood deafness and sign language. The key factors controlled across the studies are age of L1 acquisition, the…

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…

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.

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…

Presents study which explored metalinguistic abilities of prelingually deaf children who are users of Signed English with regard to their explicit segmentation of Signed English sentences into words. Subjects exhibited varying abilities that increased with age and were similar to developmental patterns in hearing populations. (Author/BK)

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)

Examines whether manually coded English (MCE) sign language systems are learnable. Reading achievement and expressive English skills of deaf students educated using only a MCE sign system were examined. Deaf students had expressive English skills comparable to hearing students in respect to syntactical and lexical skills but were deficient in…

Describes research into the correspondence between speech and sign language by looking at simultaneous communication as it is used by fluent deaf persons. The study aims to determine what relationship, if any, exists between the morpheme level and the message level of utterances in discourse. (SED)

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.

Evaluates the contribution of visuo-gestural modality versus linguistic factors in determining the order of elements in sign language. The results of a study show that Italian Sign Language differs along significant lines from both spoken Italian and pantomime. (22 references) (GLR)

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)

Because the relationship of gesticulation to sign language has not received much research attention, this study considers gesture and sign among users of signed and oral languages. Results suggest that gestures produced by deaf individuals can be distinguished from the sign language in which they are embedded, including their semantic and…
