This study aimed to detect patterns in clause construction structural changes produced by four participants aged 9;5-13;7 (years;months) with motor speech disorders who used speech-generating devices. Sequences of adult-child interactions, drawn from the data of a larger study focused on enhancing vocabulary and grammar skills, were examined. This current study comprises a secondary analysis of a corpus of 29 conversations totalling 808.36 min, analysing clause structures by type, linguistic complexity, and intensity of adult prompts (number of turns). Results show that, over time, the participants' clause structure complexity increased through addition of phrase-internal elements such as inflections, articles, and prepositions. Use of specific grammatical elements followed the developmental stages observed in children with typical development. For all participants, the personal pronoun (first-person singular) emerged before , (third-person singular), and or (plural). Participants with the highest number of adult-child co-constructed clauses also had the highest number of well-formed clauses. The intensity of adult prompts increased as clause structures became more complex and as participants needed more support. Implications for practice and theory are discussed.
本研究旨在通过对四名患有运动性言语障碍的 9 岁 5 个月至 13 岁 7 个月儿童使用言语生成设备后产生的分句结构变化进行模式检测。本研究从一项旨在提高词汇和语法技能的更大规模研究的数据中抽取了一系列成人与儿童的互动序列。本研究是对一个由 29 次对话组成的语料库（总计 808.36 分钟）进行的二次分析，通过类型、语言复杂性和成人提示（回合数）的强度来分析分句结构。结果表明，随着时间的推移，参与者的分句结构复杂性通过添加内部词素（如屈折、冠词和介词）而增加。特定语法元素的使用遵循了与典型发展儿童相同的发展阶段。对于所有参与者，第一人称单数的 （personal pronoun） 都出现在 （third-person singular）、 或 （plural） 之前。与成人共同构建的分句数量最多的参与者也有最多数量的结构正确的分句。随着分句结构变得更加复杂，以及参与者需要更多的支持，成人提示的强度也在增加。讨论了对实践和理论的启示。
