Abstract

The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12 children and youth who used graphic symbol-based AAC. The specific aims of the current study were to (a) describe vocabulary composition across different levels of expressive vocabulary and (b) analyze the relationship between global measures of expressive vocabulary and the use of grammar in individuals who use aided AAC. A series of multiple linear mixed effect regression analyses showed a positive predictive association between overall vocabulary size and the use of closed-class words, and a positive relationship between the use of verbs and the use of closed-class words. Additionally, the use of verbs had a significant positive association with the use of inflectional morphology, while the use of nouns did not. Theoretical and practical implications of these findings are discussed.

儿童和青少年使用增强型和替代型交际时词汇和语法的关系。

本研究调查了使用图形符号辅助增强和替代交际（AAC）的个体的词汇和语法之间的关系。数据来自60份概括会话的成绩单，这是之前两项干预研究的一部分，旨在改善12名使用基于图形符号的AAC的儿童和青少年的表达词汇和语法。本研究的具体目的是（a）描述不同表达性词汇水平的词汇构成，以及（b）分析使用辅助AAC的个体表达性词汇的整体测量与语法使用之间的关系。一系列多元线性混合效应回归分析显示，整体词汇量与闭类词的使用之间存在正预测相关性，动词的使用与闭类语的使用之间也存在正相关关系。此外，动词的使用与屈折形态的使用有显著的正相关，而名词的使用则没有。讨论了这些发现的理论和实践意义。

期刊介绍： As the official journal of the International Society for Augmentative and Alternative Communication (ISAAC), Augmentative and Alternative Communication (AAC) publishes scientific articles related to the field of augmentative and alternative communication (AAC) that report research concerning assessment, treatment, rehabilitation, and education of people who use or have the potential to use AAC systems; or that discuss theory, technology, and systems development relevant to AAC. The broad range of topic included in the Journal reflects the development of this field internationally. Manuscripts submitted to AAC should fall within one of the following categories, AND MUST COMPLY with associated page maximums listed on page 3 of the Manuscript Preparation Guide. Research articles (full peer review), These manuscripts report the results of original empirical research, including studies using qualitative and quantitative methodologies, with both group and single-case experimental research designs (e.g, Binger et al., 2008; Petroi et al., 2014). Technical, research, and intervention notes (full peer review): These are brief manuscripts that address methodological, statistical, technical, or clinical issues or innovations that are of relevance to the AAC community and are designed to bring the research community’s attention to areas that have been minimally or poorly researched in the past (e.g., research note: Thunberg et al., 2016; intervention notes: Laubscher et al., 2019).
