E-book Simplified Signs : A Manual Sign-Communication System for Special Populations, Volume 2.
Many children and adults experience considerable difficulty producing or understanding a spoken language despite having adequate hearing levels. Some of these persons may benefit from learning a full and genuine sign language, such as one of the sign languages used by members of a Deaf1 community. They may acquire a substantial vocabulary of signs and learn to combine them into complex sign utterances. Unfortunately, many other individuals make only very minimal progress in acquiring sign language skills. More specifically, a number of children with autism, an intellectual disability, or cerebral palsy fail to attain the signing skills necessary for effective communication through a full sign language.Because of the difficulties many of these children experience learning a spoken language or a full and genuine sign language, we developed a sign-communication system that would be easier for them (and members of their families) to learn and to produce. For manual signs to be relatively easily learned and remembered, previous research had shown that the signs needed to have clear ties to what they stood for (their referents). That is, signs would need to resemble or have readily discernible ties to the objects, actions, or properties they represented. For manual signs to be formed accurately, they would need to be composed of handshapes, locations, and movements that were relatively easy to produce. These two principles—selecting or developing signs. with largely transparent meanings and that were also easy to form or produce—guided our decisions as to which signs to include in our simplified sign-communication system.In addition to children who never acquire facility in a spoken language or a full and genuine sign language, there are many other individuals who we hope will benefit from the use of our simplified manual signs. One such group consists of adults who have experienced a loss in their abilities to produce or understand speech (a condition known as aphasia), often after suffering a stroke. Other groups may also wish to learn and use our Simplified Signs. Persons traveling overseas, parents planning an international adoption, preschool teachers, language therapists, and persons trying to acquire a foreign language vocabulary may find our system beneficial as well. Regardless of the particular reasons why someone may wish to learn and use our Simplified Signs, we hope that our system will serve to enhance their abilities to communicate effectively with others.
