关于自闭症谱系障碍 (ASD) 儿童和正常发育儿童 (TD) 在处理面部时是否表现出不同的眼球运动模式一直存在相当大的争议。我们使用一种新颖的多方法研究了 ASD 和年龄和智商匹配的 TD 儿童的面部扫描。我们发现自闭症儿童通常花在观察整个脸部的时间较少。在控制了这种差异后，自闭症谱系障碍儿童对除眼睛区域之外的其他面部部位的注视，以及他们面部部位之间的扫描路径与年龄匹配或智商匹配的 TD 组相当。相比之下，在眼部区域，ASD 儿童的扫描与两个 TD 组的扫描显着不同：（a）ASD 儿童对右眼的注视明显较少（从观察者的角度来看）； (b) 自闭症儿童的注视更偏向左眼区域； (c) ASD 儿童注视左眼下方，而 TD 儿童注视眼睛的瞳孔区域。因此，自闭症谱系障碍（ASD）儿童在面部扫描方面不存在普遍异常。相反，他们的异常仅限于眼睛区域，可能是由于他们强烈倾向于避免目光接触。
There has been considerable controversy regarding whether children with autism spectrum disorder (ASD) and typically developing children (TD) show different eye movement patterns when processing faces. We investigated ASD and age- and IQ-matched TD children's scanning of faces using a novel multi-method approach. We found that ASD children spent less time looking at the whole face generally. After controlling for this difference, ASD children's fixations of the other face parts, except for the eye region, and their scanning paths between face parts were comparable either to the age-matched or IQ-matched TD groups. In contrast, in the eye region, ASD children's scanning differed significantly from that of both TD groups: (a) ASD children fixated significantly less on the right eye (from the observer's view); (b) ASD children's fixations were more biased towards the left eye region; and (c) ASD children fixated below the left eye, whereas TD children fixated on the pupil region of the eye. Thus, ASD children do not have a general abnormality in face scanning. Rather, their abnormality is limited to the eye region, likely due to their strong tendency to avoid eye contact.
