【摘要】：实验以眼动追踪技术为手段,考察自闭症儿童对不同信息特征表情图片的视觉扫描特征,探讨自闭症表情加工的机制。结果发现:(1)看真人表情时,自闭症儿童对高兴、悲伤的整脸扫描时间无显著差异,均高于愤怒和恐惧,对愤怒的整脸扫描时间高于恐惧;(2)看真人表情时自闭症儿童对高兴、悲伤表情的眼睛区域和嘴巴区域扫描时间无差异,对恐惧和愤怒的嘴巴区域扫描时间显著多于眼睛区域;(3)信息特征削弱对自闭症儿童面孔表情视觉扫描产生了影响,随着削弱程度的增加,自闭症儿童对表情图片的嘴巴区域扫描时间增加,对眼睛区域的扫描时间减少。根据实验结果,认为自闭症儿童对表情的加工主要受到表情信息特征的影响,随着信息特征的变化,会对视觉注意进行调整,以获得对表情的充分加工。
[Abstract]:Eye movement tracking technique was used to investigate the visual scanning features of different information feature facial expressions in autistic children and to explore the mechanism of autism facial expression processing. The results showed that there was no significant difference in the overall scan time between happy and sad faces of autistic children, which was higher than that of anger and fear, while the whole face scanning time of angry children was higher than that of fear when watching real human expressions.) when looking at real human expressions, autistic children were happy with each other. There was no difference in the scanning time between the eye and mouth regions of sad expressions, and the information characteristics of fear and anger were significantly longer than those of eyes.) the impairment of information features had an impact on the visual scan of facial expressions in autistic children. As the degree of impairment increases, the scanning time of the mouth area of the expression image increases, and the scanning time of the eye area decreases. According to the experimental results, it is considered that the expression processing of autistic children is mainly affected by the facial expression information characteristics. With the change of the information characteristics, the visual attention will be adjusted to obtain the full processing of the expression.
