Background: Spoken and gestural communication proficiency varies greatly among autistic individuals. Three studies examined the role of oral- and manual-motor skill in predicting autistic children's speech development. Methods: Study 1 investigated whether infant and toddler oral- and manual-motor skills predict middle childhood and teenage speech…

Aphasic adults (N=16) with severe auditory comprehension impairment were evaluated for comprehension of redundant and nonredundant spoken and/or gestured messages. Results indicated redundancy was not reliably superior to spoken messages alone. (Author/DB)

The reliability of the Central Institute for the Deaf (CID) Everyday Sentence Lists was studied under receptive English simultaneous communication with 43 National Technical Institute for the Deaf (NTID) students and under manual communication conditions with 40 NTID students. Results indicated that the CID lists are reliable measures under both…

Investigated with 296 hearing impaired young adults and adults was the effect of delay between auditory and visual aspects of the speech message in an oral-manual interpreting situation. (Author/CL)

The study of effects of mode (manual only, manual plus oral, and manual plus oral plus aural) and language (Signed English or American Sign Language) on the comprehension of deaf students (mean age 16 years) found no significant treatment effect for mode of presentation; there was an interaction between languages and mode.

Receptive communication skills of 118 severely and profoundly deaf persons, (9-20 years old) were assessed by a multiple-choice pictorial test. The most efficient method of communication was found to be reading, followed by total communication and manual communication; oral methods were clearly the least effective. (Author/CL)

Thirty-three deaf college students were tested on ability to read fingerspelled words and letters and computerspelled words and letters, 19 hearing students were tested on the latter task alone, and 12 Ss highly experienced in fingerspelling were tested on the former task alone. On the word task Ss were scored on percent of words correct, with…

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)

To assess competency in American Sign Language (ASL) and manually coded English (MCE), 219 National Technical Institute for the Deaf students, judged to be skilled signers, viewed videotaped stories, one in ASL and one in MCE, followed by true/false questions in the same language as the story. (Author/PHR)

A review of problems with using such manual communication systems as cued speech, fingerspelling, Signed or Manual English, American Sign Language, and Pidgin Sign provides a rationale for using a combination of American Sign Language and Pidgin Sign and a few markers from Signed English for a Total Communication system.

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…

Approximately 290 deaf college freshmen participated in a study of the relationship between perceived and actual abilities in eight communication modes (including reading, writing, speech reading with and without sound, and reception of manual and simultaneous communication). Ss rated their abilities before and after a communication course. Actual…

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

The study measured hearing-impaired (N=106) students' reception of language presented via five modes: oral, aural, manual, oral-aural;, and simultaneous manual and oral. The simultaneous manual and oral and the manual modes received the highest ratings. Results are discussed in terms of theories of cognitive processing and selective attention.…
