This study examined keyword signing (KWS), a communication approach used with nonspeaking individuals. Acoustic measures and judgments of 20 adult listeners were used to evaluate KWS and Spoken-Only narratives. KWS narratives were produced with a slower articulation rate, because of increased pause and speech segment duration and increased pause…

The manual teaches SignFont, a written form of sign language. Following a brief introduction, the first of three major sections describes the SignFont alphabet, structured according to the parts of every sign that is written (handshape, action area, location, movement). The second section discusses in greater detail how the SignFont characters are…

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…

Four nonverbal autistic children (10-15 years old) were taught expressive sign labels for common objects, using a training procedure that consisted of prompting, fading, and stimulus rotation. (Author/BD)

Total communication procedures were used with three severely mentally retarded children (mental ages 2 to 4) to examine the effects of receptive speech on the acquisition and maintenance of manual signing. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. (Author/JW)

Acquisition of passive and active vocabulary in sign and oral language was analyzed in 2 children congenitally deaf, through age 54 months. Acquisition of sign occurred more quickly than oral language. Production of active nouns, function words, and "wh" question words in sign was equivalent to that of hearing peers, and was later transferred to…

A transfer of stimulus control procedure was used to teach a 14-year-old retarded deaf girl manual signing skills. (CL)

This review of research on language development of hearing children of deaf parents identified three areas of focus: (1) oral language development; (2) sign language development; and (3) mode of communication--oral and/or manual. Areas of future study are suggested. (Author/DB)

Reviews a study on deaf native sign language. Indicates that the modification of natural perceptual categories after language acquisition is not bound to a particular transmission modality, but rather can be a more general consequence of acquiring a formal linguistic system. (Author/SK)
