Eye-tracking is often used to study attention in children with autism spectrum disorder (ASD). Previous research has identified multiple atypical patterns of attention in children with ASD based on areas-of-interest analysis. Fewer studies have investigated gaze path, a measure which is dependent on the dynamic content of the stimulus presented. Here, rather than looking at proportions of looking time to areas of interest, we calculated mean fixations frame-by-frame in a group of typically developing children (36 to 72 months) and determined the distance from those typical fixations for 155 children with ASD (27-95 months). Findings revealed that distance from the typical scan path among the children with ASD was associated with lower communication abilities and greater ASD symptomatology.
眼动追踪技术常用于研究自闭症谱系障碍（ASD）儿童的注意力。基于兴趣区域分析，先前的研究已经确定了 ASD 儿童注意力的多种异常模式。但较少的研究调查了注视路径，这是一种依赖于呈现刺激的动态内容的测量方法。在这里，我们不是通过观察注视时间与兴趣区域的比例，而是在一组典型发育的儿童（36 至 72 个月）中逐帧计算平均注视次数，并确定 155 名 ASD 儿童（27 至 95 个月）的注视点与典型注视路径之间的距离。研究结果表明，ASD 儿童的扫描路径与典型路径的距离与较低的沟通能力和更严重的 ASD 症状有关。
