Across a diverse range of languages, children proceed through similar stages in their production of causal language: their initial verbs lack internal causal structure, followed by a period during which they produce causative overgeneralizations, indicating knowledge of a productive causative rule. We asked in this study whether a child not…

Two experiments questioned whether deaf signers agree on the location of sign boundaries in American Sign Language (ASL), as well as where in time the boundaries are located. Results indicated that the deaf subjects were using linguistic knowledge of ASL when making judgments of the location of sign boundaries. (SL)

Recent research in sociolinguistics has demonstrated the need for looking at language in a dynamic framework, that is, for not imposing the traditional synchronic-diachronic dichotomy on linguistic studies. Support for the dynamic framework has been given from various oral languages. This paper attempts to test variation theory with historically…

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

A study tested the hypothesis that manual encoding aids learning in the prelingually deaf. Twenty-four adults who used fingerspelling as their primary means of communication participated in two groups of a paired-associate learning paradigm, using eight study-test trial sequences. Those using fingerspelling showed more recall and a faster learning…

Systematic sampling was done of signing between five home-reared chimpanzees who had had 4-7 years of complete immersion in integrating their signing interaction into their nonverbal communication. Eight-eight percent of all signs reported fell into the social categories of reassurance, social interaction, and play. (SL)

Thirty-five deaf children with hearing parents were tested for cheremic perception. Deaf children using sign language, like hearing children using spoken language, have more difficulty discriminating between lexical items that form minimal pairs in their language than between items that differ more. (SL)

Study indicates that hearing impaired residential students are more proficient users of American Sign Language than are hearing impaired children enrolled in local, public school programs, and older such residential students are more proficient in the language than are younger students. (SL)

Describes code shifting study in communicative behavior of hearing child interacting with deaf child and mother, both of whom signed. Hearing child knew signing, but did not sign at home. Although communication change occurred, code shifting was influenced more by motivational variables and by hearing child's own flexibility with language than by…
