Early differences in sensorimotor functioning have been documented in young autistic children and infants who are later diagnosed with autism. Previous research has demonstrated that autistic toddlers exhibit more frequent head movement when viewing dynamic audiovisual stimuli, compared to neurotypical toddlers. To further explore this behavioral characteristic, in this study, computer vision (CV) analysis was used to measure several aspects of head movement dynamics of autistic and neurotypical toddlers while they watched a set of brief movies with social and nonsocial content presented on a tablet.

自闭症幼儿头部运动的复杂性分析


在年幼的自闭症儿童和后来被诊断为自闭症的婴儿中，已经记录了感觉运动功能的早期差异。先前的研究表明，与神经正常幼儿相比，自闭症幼儿在观看动态视听刺激时表现出更频繁的头部运动。为了进一步探索这种行为特征，在这项研究中，计算机视觉（CV）分析被用来测量自闭症和神经正常幼儿在观看平板电脑上呈现的一组包含社交和非社交内容的简短电影时头部运动动态的几个方面。
