This study examined the possible sources of variability in sign language mastery in two deaf children of hearing parents. The study considered the interaction of environmental and innate factors within the framework of the "Nativization" hypothesis, which suggests that all language learners initially construct a linguistic system which…

The signed and spoken language produced by 14 mothers (7 deaf and 7 hearing) to their 18-month-old deaf children was analyzed. Deaf mothers were more successful in presenting signed utterances with a salient context visible to their children. For both groups, visible and salient signed utterances were positively correlated with mothers' success in…

This study with 64 deaf employees working in either signing work groups or nonsigning workgroups found that employees' perceived empowerment was significantly higher in the signing work groups. Deaf associates in signing work groups experienced greater psychological stress and role conflicts, whereas deaf associates in nonsigning groups…

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.…
