Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by impaired social communication and the presence of restricted, repetitive patterns of behaviors and interests. Prior research suggests that restricted patterns of behavior in ASD may be cross-domain phenomena that are evident in a variety of modalities. Computational studies of language in ASD provide support for the existence of an underlying dimension of restriction that emerges during a conversation. Similar evidence exists for restricted patterns of facial movement. Using tools from computational linguistics, computer vision, and information theory, this study tests whether cognitive-motor restriction can be detected across multiple behavioral domains in adults with ASD during a naturalistic conversation. Our methods identify restricted behavioral patterns, as measured by entropy in word use and mouth movement. Results suggest that adults with ASD produce significantly less diverse mouth movements and words than neurotypical adults, with an increased reliance on repeated patterns in both domains. The diversity values of the two domains are not significantly correlated, suggesting that they provide complementary information.
自闭症谱系障碍（ASD）是一种神经发育状况，其特征是社交沟通受损，以及存在受限的、重复的行为模式和兴趣。先前的研究表明，ASD中受限的行为模式可能是跨领域现象，在多种形式中都很明显。对ASD语言的计算研究为对话过程中出现的潜在受限维度的存在提供了支持。面部运动受限模式也有类似证据。本研究使用计算语言学、计算机视觉和信息论工具，测试在自然对话中能否在患有ASD的成年人的多个行为领域检测到认知运动受限。我们的方法通过词汇使用和嘴部运动的熵来识别受限行为模式。结果表明，与神经典型成年人相比，患有ASD的成年人产生的嘴部运动和词汇明显缺乏多样性，且在这两个领域对重复模式的依赖增加。这两个领域的多样性值没有显著相关性，表明它们提供了互补信息。
