自闭症谱系障碍(ASD)儿童的认知灵活性受损在以前的文献中已有报道。本研究采用眼动跟踪技术，探讨了自闭症儿童在维度变化卡片分类(DCCS)任务中的视觉扫描模式。ASD和典型发育期(TD)儿童在计算机上完成标准化的DCCS程序，同时跟踪他们的眼球运动。行为结果证实了先前关于自闭症儿童执行功能缺陷的发现。与TD儿童相比，ASD儿童在DCCS任务中的视觉扫描模式也显示出一些特定的潜在加工。例如，与TD儿童相比，ASD儿童在切换后阶段看正确卡片的时间更短，在空白区域花费的时间更长。ASD儿童不像TD儿童那样在颜色维度上表现出偏向。文中还讨论了行为表现与眼动时刻之间的关系。
Impaired cognitive flexibility in children with autism spectrum disorder (ASD) has been reported in previous literature. The present study explored ASD children's visual scanning patterns during the Dimensional Change Card Sorting (DCCS) task using eye-tracking technique. ASD and typical developing (TD) children completed the standardized DCCS procedure on the computer while their eye movements were tracked. Behavioral results confirmed previous findings on ASD children's deficits in executive function. ASD children's visual scanning patterns also showed some specific underlying processes in the DCCS task compared to TD children. For example, ASD children looked shorter at the correct card in the postswitch phase and spent longer time at blank areas than TD children did. ASD children did not show a bias to the color dimension as TD children did. The correlations between the behavioral performance and eye moments were also discussed.
