Proposed Advantages According to a study done in 1984, it was found that compared with haphazard instruction involving no language approach whatsoever, Total Communication was proved to be beneficial when combined with the correct approach. One study entitled "Intelligibility of speech produced during simultaneous communication", 12
hearing impaired individuals were asked to audit the audio samples of 4 hearing sign language experts who had produced recordings of a Simultaneous Communication (SC) sample and a Speech Alone (SA) sample. The 12 hearing impaired individuals were asked to then determine which speech produced was clearer. After listening to both audio samples, hearing impaired listeners agreed that both SC and SA were intelligible, which is supported by previous research. Since the intelligibility of the speech was kept on par with English grammar, the study results indicate that SC is a positive tool to use with
Deaf and
Hard of Hearing children as a language model and for Deaf/Hard of Hearing adults to keep using. Another study showed the difference between a control group, families who participated in an intervention program that offered services such as classes on Total Communication, private teachers for the child and a deaf adult who came to the families house, and another group of families who used TC, but did not have as much intervention as the control group. The results showed that intervention did work, and that it positively correlated with the communication skills show by the control group's children. The children showed advanced cognitive skills, including comprehension and expression, specifically related to time. When working with two separate modes of communication, the one that comes naturally for the user will be the more prominent mode. A study conducted in 1998 showed that signing and speaking at the same time results in a slower approach to instruction than if just one
modality was used to express language. == Methods of Total Communication ==
