This study characterizes the success and effectiveness of adult-directed communications of youth with mental retardation and little or no functional speech who used the System for Augmenting Language (SAL), in concert with vocalizations and gestures, to communicate over a 2-year period. Subjects were introduced to the SAL, a speech-output communication device used during daily interactions, to encourage attempts at communication either at home or school. All subjects used the SAL at home and at school during the second year. Results indicate that subjects used the SAL with their extant forms of communication, particularly vocalizations. Extant communications were more successful than SAL communications, although the environment influenced the success of all the youth's communications. The SAL, however, was more effective than vocalizations or gestures in conveying information and interacting with adults in both environments. Maintenance, generalization, and implications for practice are discussed.
本研究描述了使用语言增强系统（SAL）的成年智障青年（其功能性言语很少或没有）在两年时间里通过与发声及手势配合进行交流的成效。研究对象被引入SAL，这是一种在日常互动中使用的语音输出交流设备，以鼓励他们在家或学校尝试交流。第二年，所有研究对象都在家和学校使用SAL。结果表明，研究对象将SAL与他们现有的交流方式，特别是发声相结合使用。现有的交流方式比使用SAL的交流更成功，尽管环境会影响所有青年交流的成效。然而，在两种环境中，SAL在传达信息和与成年人互动方面比发声或手势更有效。文中还讨论了维持、推广以及对实践的启示。
