处理情绪面部表情的困难被认为是自闭症谱系障碍（ASC）儿童的中心特征。此外，人们对使用能够表达情感的虚拟化身作为旨在提高这些人的社交技能的干预越来越感兴趣。化身的一个潜在用途是，它们可以增强面部识别并引导注意力。但是，这方面需要进一步调查。我们研究的目的是评估眼睛注视过程中的差异，在儿童与ASC时，他们看到的头像表情与真实的面孔相比，表达的情绪。眼动追踪方法被用来比较儿童与ASC之间的化身和真实的面孔的表现。采用重复测量的一般线性模型来了解刺激的哪些特征会影响刺激的注视时间。进行生存分析，以了解化身和真实的面孔之间的探索行为的差异。通过配对t检验评估情绪识别准确性和注视次数之间的差异。我们的研究结果证实，自闭症儿童有更高的能力来处理和识别情绪时，这些都是由头像的脸。自闭症儿童更容易被嘴巴或眼睛所吸引，这取决于刺激类型（化身或真实的）和刺激所表达的情感。此外，他们更容易被表达负面情绪（愤怒和悲伤）的虚拟面孔和表达惊讶的真实的面孔所吸引。在幸福感方面没有发现差异。最后，他们表现出更高程度的探索头像的脸。所有这些元素，例如对化身的兴趣和对眼睛的注意力减少，可以为规划有效的干预提供重要的元素。
Difficulties in processing emotional facial expressions is considered a central characteristic of children with autism spectrum condition (ASC). In addition, there is a growing interest in the use of virtual avatars capable of expressing emotions as an intervention aimed at improving the social skills of these individuals. One potential use of avatars is that they could enhance facial recognition and guide attention. However, this aspect needs further investigation. The aim of our study is to assess differences in eye gaze processes in children with ASC when they see avatar faces expressing emotions compared to real faces. Eye-tracking methodology was used to compare the performance of children with ASC between avatar and real faces. A repeated-measures general linear model was adopted to understand which characteristics of the stimuli could influence the stimuli’s fixation times. Survival analysis was performed to understand differences in exploration behaviour between avatar and real faces. Differences between emotion recognition accuracy and the number of fixations were evaluated through a paired t-test. Our results confirm that children with autism have higher capacities to process and recognize emotions when these are presented by avatar faces. Children with autism are more attracted to the mouth or the eyes depending on the stimulus type (avatar or real) and the emotion expressed by the stimulus. Also, they are more attracted to avatar faces expressing negative emotions (anger and sadness), and to real faces expressing surprise. Differences were not found regarding happiness. Finally, they show a higher degree of exploration of avatar faces. All these elements, such as interest in the avatar and reduced attention to the eyes, can offer important elements in planning an efficient intervention.
