The basic impoverishment of deafness is not lack of hearing but lack of language. To illustrate this, we have only to compare a 4-year-old hearing child, with a working vocabulary of between 2,000 and 3,000 words, to a child of the same age, profoundly deaf since infancy, who may have only a few words at his command. Even more important than…

The English language development of an unselected group of 20 hearing impaired children (mean age approximately four) taught Signed English was studied over a four-year period. (Author/PHR)

Mothers of four 6- and 7-year-old autistic classmates were taught to use manual signs with verbalizations to aid development of appropriate communicative behavior and to deter undesirable behavior in their children. (Author)

Ten children and adolescents with severe mental retardation were assigned in matched pairs to either a lexigram augmentative communication condition (graphic symbols) or a control condition (social stimulation). The three subjects who successfully acquired lexigrams also exhibited changes in attention, intentional communication, and sociability.…

Three papers comment on a paper by Abrahamsen et al (EC 212 728) on concomitants of success in acquiring an augmentative communication system (AAC) by persons with severe mental retardation. Comments focus on design and methodological requirements, principles of AAC, and sequence and process in indirect aspects of communicative gains. (DB)

Examined the development of communicative competence in deaf children and its interactions with use of communicative gestures and/or words. Data indicated (1) the use of communicative gestures increased with age while speech remained constant; and (2) the number of gestures used correlated with communicative accuracy. Difficulty level influenced…

A program was implemented to increase the manual signing of five profoundly retarded (mean age, 19 years) and four autistic (mean age, 9 years) youth within their daily environment. (Author)

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.…

Two experiments compared signed and written stories by deaf 7- to 15-year-olds with oral and written stories by hearing age-mates. Found that the signed and oral stories had similar discourse structures as indicated by patterns of causal goal-action-outcome episodes. The grammatical and lexical character of deaf students' written stories lagged…

The comprehension of 30 severely and profoundly deaf students (ages 10 to 17) was evaluated under 11 communication conditions involving individual and combined presentations of lipreading, listening, fingerspelling, and signed English. Severely deaf students scored higher than profoundly deaf students under all but one condition, and all students…

THE ILLINOIS COMMUNICATION SCALE WAS DEVELOPED ON 16 MM COLOR FILM TO ASSESS THE RECEPTIVE COMMUNICATION ABILITIES OF DEAF CHILDREN BETWEEN 6 AND 14 YEARS. FORMS WERE CONSTRUCTED TO MEASURE (1) AUDITORY RECEPTION, (2) LIPREADING AND LISTENING, (3) LIPREADING ONLY, (4) FINGERSPELLING, AND (5) LANGUAGE OF SIGNS. EACH FORM HAD 5 SUBPARTS (1)…
