OBJECTIVE
Previous research found that autism spectrum disorder (ASD) was characterized by eye avoidance of threatening facial expressions. However, it still remains unclear as to whether these abnormalities are present in parents of children with ASD. Our study aimed to investigate the gaze patterns of parents of children with ASD in the threatening facial expressions.
METHODS
Thirty-four parents of children with ASD and 35 parents of typically developing (TD) children participated in our study. We investigated the total fixation time of participants when they viewed different facial expression (eg, happy, fearful, angry, sad) videos and examined changes in the fixation duration over time.
RESULTS
We observed the following: a) the total fixation time of the parents of children with ASD on the eyes of fearful faces was significantly shorter than that of the normal group, and the difference lasted for five seconds (four to six seconds, eight to nine seconds) throughout the process; and b) The parents of children with ASD avoided the eyes of angry expression faces at around five seconds after the stimulus onset.
CONCLUSION
We concluded that parents of children with ASD tended to avoid the eyes of threatening expression faces while viewing the dynamic emotions video.
目的
先前的研究发现，自闭症谱系障碍（ASD）的特征是回避带有威胁性的面部表情的眼睛。然而，目前仍不清楚这些异常是否存在于ASD儿童的父母身上。我们的研究旨在调查ASD儿童的父母在面对带有威胁性的面部表情时的注视模式。
方法
34名ASD儿童的父母和35名发育正常（TD）儿童的父母参与了我们的研究。我们调查了参与者观看不同面部表情（如高兴、恐惧、愤怒、悲伤）视频时的总注视时间，并研究了注视持续时间随时间的变化。
结果
我们观察到以下情况：a）ASD儿童的父母对恐惧面孔眼睛的总注视时间显著短于正常组，且在整个过程中这种差异持续了5秒（4至6秒、8至9秒）；b）ASD儿童的父母在刺激开始后约5秒时回避愤怒表情面孔的眼睛。
结论
我们得出结论，ASD儿童的父母在观看动态情绪视频时倾向于回避带有威胁性表情面孔的眼睛。
