We longitudinally investigated the development of deictic and general accompanying gestures in one 5-year-old boy with autism spectrum condition (ASC) and intellectual disability. The investigation was performed during an intervention focusing on phonological segments. The purpose was to see whether gestures developed in conjunction with language. We found that deictic and general accompanying gestures increased during the study, despite not being trained. There was also a positive temporal correlation between deictic gestures and speech. Contrary to the expectations in this case, declarative gestures were frequent and increased, while imperative decreased during the period of intervention. Furthermore, we detected a specific kind of general accompanying non-context-sensitive gestures that may be involved in the retrieval of phonemes and syllables. Speech prosody was also analysed in relation to these gestures.
我们纵向研究了一名患有自闭症谱系障碍（ASC）和智力障碍的5岁男孩指示性手势和一般伴随手势的发展情况。该研究是在一项针对音段的干预过程中进行的。目的是观察手势是否与语言同步发展。我们发现，尽管没有进行训练，但在研究过程中指示性手势和一般伴随手势有所增加。指示性手势与言语之间也存在正相关的时间关系。与该案例中的预期相反，在干预期间，陈述性手势频繁出现且有所增加，而祈使性手势则减少了。此外，我们检测到一种特定类型的一般伴随性非情境敏感手势，其可能参与音素和音节的提取。我们还分析了与这些手势相关的言语韵律。
