Examination of the nature and quality of deaf children's referential messages to their mothers, the outcome of such messages, and the reformulations of "failed" messages. Deaf children 6-10 years old, from oral or bimodal educational programs, were tested in two tasks involving identification and description of a picture. (Author/BN)

Two studies explored linguistic development in sign and speech of 10 youth (ages 12-16) with severe intellectual impairments who used manual signs (Makaton vocabulary) for communication. Analysis of semantic relations, lexical development, and word order suggested the children's language had not developed beyond mean length of utterance stage 1.…

The study assessed the use of Blissymbols in the spoken and signed language development of 10 school-aged (mean age 11.5 years) children with developmental dysphasia of whom four also were mildly retarded. The students' expressive abilities in signed and spoken words were initially assessed before the Bliss teaching began, and then again after 1…

This observational study examined the development and use of communication in a pair of deaf and hearing monozygotic twins from 13 to 36 months of age. Both children were enrolled in a total communication preschool program. In contrast to the hearing twin, the deaf twin used imitative (rather than responsive) signs and gestures. (Author/DB)

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.…

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…

The use of Makaton signs was investigated with 49 British children (ages 4-13) with severe learning difficulties. Teacher-directed settings were associated with more use of signs but limited pragmatic functions. Free play settings were associated with less sign use but more varied functions. In both settings, most spoken and signed language was…

This longitudinal study first administered the Uzgiris and Hunt scales (to predict learning of manual signs) to 34 children (mean age 5) with severe and profound mental retardation. Evaluation four years later indicated that achievement of stage five on the Uzgiris and Hunt scales was necessary for even minimal learning and use of manual signs.…
