面孔群持续时间对自闭症儿童表情威胁知觉影响的眼动研究

On the Eye Movement Involving the Effect of the Duration of Facial Expressions on Autistic Children's Treat Perception

以自闭症儿童和普通儿童各28名为被试,通过面孔群图片视觉搜索的方式,借助Tobii X120记录被试的眼动及行为反应情况,探讨自闭症儿童表情威胁知觉的特点。结果发现:自闭症儿童对面孔群图片的威胁知觉受到持续时间的限制,表现出对目标表情搜索短时快反应的特点;自闭症儿童威胁知觉具有情绪突显效应,正性加工优势明显;自闭症儿童威胁知觉的眼动特征,能为其临床研究和早期干预提供重要循证依据。

The present study,based on a survey of 28 autistic children and 28 typically developing children,a visual search of face pictures,and the eye movement and behavioral responses recorded with a Tobi X120 Eye-Tracker,aims to explore the characteristics of the threat perception of facial expressions in autistic children.The results show the following:The autistic children's threat perception of face pictures is limited by the duration,featured by search of target face pictures in a short time and rapid response to the targct face pictures;their threat perception has an elfect of emotional superiority,especially in the positive processing advantages;and their eye movement in the threat perception can provide an important evidence-hased hasis for clinical research and early interventions.
