摘要

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 childrena??s fixations and scanning of faces using a novel multi-method approach inclusive of the traditional AOI approach, a data-driven analysis, and a saccade path analysis. We found that ASD children spent less time looking at the whole face generally. After controlling for this difference, ASD childrena??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 childrena??s scanning differed significantly from that of both TD groups in a highly specific manner. First, ASD children fixated significantly less on the right eye than both TD groups. Second, unlike both TD groups, ASD childrena??s fixations were more biased towards the left eye region. Third, their fixations to the left eye region were different from those of both TD groups: Whereas TD children fixated on the pupil region of the eye, ASD children fixated below the left eye as though they were trying to avoid direct eye contact. We conclude that ASD children do not have a general and pervasive abnormality in face scanning. Rather, their abnormality is limited only to the eye region, likely due to their strong tendency to avoid eye contact. This abnormality may be partially responsible for ASD childrena??s significantly poorer face recognition performance than TD children.
