Bonvillian, nicole Kissane lee, Tracy T. Dooley, anD Filip T. loncKe l Simplifed Signs presents a system of manual sign communicaton intended for ee Simplifed Signs special populatons who have had limited success mastering spoken or full sign , D languages. It is the culminaton of over twenty years of research and development ooley by the authors. The Simplifed Sign System has been developed and tested for ease of sign comprehension, memorizaton, and formaton by limitng the complexity , of the motor skills required to form each sign, and by ensuring that each sign an visually resembles the meaning it conveys. D l Volume 1 outlines the research underpinning and informing the project, and onc places the Simplifed Sign System in a wider context of sign usage, historically K and by diferent populatons. Volume 2 presents the lexicon of signs, totalling e A Manual Sign-Communication approximately 1000 signs, each with a clear illustraton and a writen descripton of how the sign is formed, as well as a memory aid that connects the sign visually System for Special Populations to the meaning that it conveys. While the Simplifed Sign System originally was developed to meet the needs of s impli persons with intellectual disabilites, cerebral palsy, autsm, or aphasia, it may also assist the communicaton needs of a wider audience – such as healthcare F professionals, aid workers, military personnel , travellers or parents, and children ie D who have not yet mastered spoken language. The system also has been shown to s enhance learning for individuals studying a foreign language. igns Lucid and comprehensive, this work consttutes a valuable resource that will enhance the communicatve interactons of many diferent people, and will be of great interest to researchers and educators alike.

Preface and Acknowledgments The inspiration for the development of the Simplifed Sign System occurred some years ago, in the late 1980s. A former student and I had recently completed a research project that examined various factors associated with non-speaking children’s success in learning signs to communicate (Bonvillian & Blackburn, 1991). Most of the participants in that study were students diagnosed with autism at the Grafton School in Virginia. Because these students had failed to make signifcant progress in learning to speak, they had been taught to communicate through American Sign Language (ASL) signs. ASL is the principal language of the Deaf community in the United States. After the research project ended, I met with Gail Mayfeld, the director of the autism program at Grafton, to discuss the results. One of the fndings was that scores on tests of the students’ motor abilities predicted their acquisition of ASL signs. Many of the students had also obtained quite low scores on these tests of motor abilities. Furthermore, those children with more impaired motor skills tended to acquire relatively few signs and rarely combined them into more complex utterances. These results surprised me because previous investigators had consistently stated that motor skills in children with autism were largely unimpaired. These fndings, however, did not surprise Gail. As the director of a program that had used signs with children with autism for over a decade, Gail had seen frsthand the difculties that many of her students experienced with motor tasks and sign formation. Gail made a point of underlining what she perceived as a serious problem in her students’ communication training: many of them clearly had problems accurately forming the signs that they were being taught. In her opinion, the combination of the students’ motor difculties and the formational complexity of many ASL signs made her students’ sign learning only a limited success. © J. D. Bonvillian & W. B.
