研究表明,神经正常的人很难理解自闭症谱系障碍(ASD)患者的面部表情。目前的研究使用动作捕捉来客观地量化自闭症患者和非自闭症患者情绪面部表情的运动模式之间的差异。参与者戴上面部标记,有意识地模仿情绪表情。记录标记运动并按表达效价和表达强度分组。我们使用生长曲线分析来检验运动模式是否可以通过表达类型和参与者组来预测。结果显示,表达类型与组间存在显著的交互作用,情绪效价对ASD表达的影响较小。总之,这些结果支持了这样一种观点,即自闭症患者的表达与那些神经正常的人不同,而且更模糊。
Research shows that neurotypical individuals struggle to interpret the emotional facial expressions of people with Autism Spectrum Disorder (ASD). The current study uses motion-capture to objectively quantify differences between the movement patterns of emotional facial expressions of individuals with and without ASD. Participants volitionally mimicked emotional expressions while wearing facial markers. Marker movement was recorded and grouped by expression valence and intensity. We used Growth Curve Analysis to test whether movement patterns were predictable by expression type and participant group. Results show significant interactions between expression type and group, and little effect of emotion valence on ASD expressions. Together, results support perceptions that expressions of individuals with ASD are different from -- and more ambiguous than -- those neurotypical individuals’.
