A research review of 31 studies pertaining to the morphology and syntax of individuals who use augmentative and alternative communication (AAC) and who had severe speech and physical impairments (SSPI) was completed. Results suggest that, although many individuals who use AAC exhibit comprehension and expression of a wide range of grammatical structures, these individuals are at risk for experiencing grammar deficits. A wide range of individual differences was noted, both within and across many of the investigations. One of the more robust findings was that individuals tended to produce shorter utterances when they used graphic symbol-based AAC systems than would be expected, based on participant profiles; however, there appeared to be a developmental trend toward using longer utterances. There has been a dearth of research pertaining to the development and evaluation of appropriate assessment tools and intervention techniques to enhance grammar acquisition for individuals who use AAC. Considerations for developing such tools and techniques are discussed.
完成了一项针对31项研究的综述，这些研究涉及使用辅助和替代沟通（AAC）且有严重言语和身体障碍（SSPI）的个体的形态学和句法。结果表明，尽管许多使用AAC的个体表现出对广泛语法结构的理解和表达，但这些个体仍有出现语法缺陷的风险。在许多调查中，无论是在调查内部还是调查之间，都注意到了广泛的个体差异。一个较为显著的发现是，与基于参与者特征所预期的情况相比，个体在使用基于图形符号的AAC系统时往往会说出更短的话语；然而，使用更长话语似乎存在一种发展趋势。关于开发适当的评估工具和干预技术以促进使用AAC的个体的语法习得，相关研究一直匮乏。本文讨论了开发此类工具和技术时的注意事项。
