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…

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. (Author/DB)

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)

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)

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…

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.…

Speech, speechreading, and manual reception skills of 78 deaf students were evaluated over a 2-year interval of residency at the National Technical Institute for the Deaf (NTID) in order to determine the relative stability of these skills within an integrated environment which stresses the use of amplification and oral-aural instruction. (Author)

Deaf children (N=52) were administered a videotaped presentation of a vocabulary test under one of five conditions: Total Communication (TC) with audio; TC without audio; Manual Communication (MC) with no mouth movement; Oral Communication (OC) with audio; and OC without audio. Modes using MC or TC yielded performances significantly superior to OC…

This study compared teachers' ratings of the speech intelligibility and receptive communication skills of 15 severely deaf and 15 profoundly deaf students using five methods of communication; and students' scores on tests of these receptive communication methods. Teachers' ratings generally were lower than test scores, with low correlations…

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…
