Signing systems that attempted to represent spoken language via manual signs -- some invented, and some borrowed from natural sign languages -- have historically been used in classrooms with deaf children.

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.

Twenty-eight deaf adolescents enrolled in a day-class program for the hearing impaired were administered a battery of four short factual stories using oral, manual, simultaneous, and interpreted modalities of communication. (Author/PHR)

The study with 23 severely hearing impaired adolescents found that subjects using cued speech performed highest on Piagetian conservation problems, the oral-aural group performed better on linguistically-sensitive metaphor problems. Differences were not, however, statistically significant. (Author/DB)

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…
