This study of eight severely mentally retarded nonverbal adults examined the form and function characteristics of intentional communication acts. Subjects who engaged in only contact gestures produced no protodeclarative type communication acts, whereas subjects who used distal as well as contact gestures produced some protodeclaratives.…

This study investigated speaking rate and voice onset time (VOT) in speech produced during simultaneous communication (SC) by speakers with normal hearing. The somewhat enlarged voicing contrast during SC was consistent with previous findings regarding the influence of rate changes on the temporal fine structure of speech and voicing contrast…

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…

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)

The current state of research into augmentative and alternative communication (AAC) systems is reviewed, and four dimensions of the study of communication handicap are described: structural, developmental, pragmatic (interaction), and technological. Recommendations regarding standardized research reporting procedures are offered in light of the…

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 examined the relationship between language and mathematics with 11 classes of deaf students taking Algebra 1 or Algebra 2 at the Gallaudet University School of Preparatory Studies. Specifically, the study attempted to predict the difficulty of a variety of relatively simple algebra problems based on the abstractness of the math and the…

Examined were message-receiving skills of schoolchildren in relation to their mother's messages. Participants were hearing children four, six, and eight years of age and deaf children six to 10 years of age. Findings revealed that mothers achieved high levels of communicative success with their six- and eight-year-old hearing children but…

Experienced deaf-blind users (N=10) of sign language tested their ability to receive signed messages including isolated signs and sentences. A set of 122 isolated signs was received with an average accuracy of 87%. Signed sentence reception accuracy ranged from 60-85%, with errors accounted for primarily by deletions and phonological or…

Comparison of 149 deaf and 121 hearing college students on the Approaches to Studying Inventory found the impact of deafness relatively slight. Discriminant analysis indicated deaf students, especially those who preferred sign communication, had more difficulty with relating ideas on different topics although they were more likely to adopt a…

The study compared scores of 2 groups of hearing-impaired students ages 5 to 12 years on a literacy battery. Subjects (n=73) were receiving instruction which either completely encoded spoken English or incompletely encoded spoken English. Those receiving completely encoded English instruction tended to score higher on achievement tests especially…

Twelve stories were told to four profoundly deaf and hard-of-hearing preschool children, using either pure American Sign Language (ASL), pure Signing Exact English (SEE) II, or SEE II with ASL features and structures. Children participated more during story conditions that were either pure ASL or contained ASL signing. (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.…

In order to better evaluate bilingualism in deaf children, this study examined whether observers (N=37) from different backgrounds would agree on deaf children's use of either American Sign Language (ASL) or English signing. Observers represented a range of background experience in a variety of schools and programs; 6 were deaf; 31 were hearing;…

Questions asked by parents of 12 young hearing children were compared with those asked by hearing parents of 17 preschoolers with deafness who used various linguistic input models (i.e., oral English only, cued speech, signed/manual English). Similar parent questioning strategies were found among groups matched for mean length of utterance.…
