This study investigated the oculomotor performance in children with autism spectrum disorder (ASD) during a face-to-face conversation. A head mounted eye tracker recorded the eye movements in 20 children with ASD and 23 children with typical development (TD). Group comparisons were conducted on the randomness and the quantity of eye movement. The amount of time needed to reveal group difference was also examined. Results showed that the randomness of eye movement was significantly higher at all examined time durations, and the amount of eye movement was significantly greater within 3 s in the ASD group. These findings demonstrated an atypical pattern of oculomotor dynamics in children ASD, which might facilitate the objective identification of ASD during daily social interaction.

本研究调查了自闭症谱系障碍 (ASD) 儿童在面对面交谈中的动眼神经表现。头戴式眼动仪记录了 20 名自闭症儿童和 23 名典型发育 (TD) 儿童的眼球运动。对眼球运动的随机性和数量进行分组比较。还检查了揭示组间差异所需的时间。结果表明，在所有检查的时间段内，眼球运动的随机性明显更高，而 ASD 组在 3 秒内眼球运动量明显更大。这些发现证明了儿童 ASD 的动眼神经动力学的非典型模式，这可能有助于在日常社交互动中客观识别 ASD。
