患有自闭症谱系障碍（ASD）的青少年和年龄匹配的对照组在虚拟现实（VR）环境中参与了动态面部情绪识别任务。参与者通过电脑生成的虚拟形象识别出不同强度的面部表情。该系统评估了参与者的表现（即准确性、信心评级、反应延迟和刺激辨别），以及参与者如何使用眼动仪使用他们的目光来处理面部信息。两组参与者在不同程度的基本面部表情识别上的准确率相似。尽管有相似的表现特征，ASD参与者在没有知觉辨别缺陷的情况下，对他们的反应的信心较低，并且在注视模式上有很大的变化。这些结果支持了一个假设，即自闭症患者的情绪和面部识别缺陷与信息处理的根本差异有关。我们讨论了这一发现在VR环境中的影响，涉及潜在的未来应用和范例，不仅针对增强的性能，而且还针对能够适应个体处理差异的智能系统中增强的社会信息处理。
Teenagers with autism spectrum disorder (ASD) and age-matched controls participated in a dynamic facial affect recognition task within a virtual reality (VR) environment. Participants identified the emotion of a facial expression displayed at varied levels of intensity by a computer generated avatar. The system assessed performance (i.e., accuracy, confidence ratings, response latency, and stimulus discrimination) as well as how participants used their gaze to process facial information using an eye tracker. Participants in both groups were similarly accurate at basic facial affect recognition at varied levels of intensity. Despite similar performance characteristics, ASD participants endorsed lower confidence in their responses and substantial variation in gaze patterns in absence of perceptual discrimination deficits. These results add support to the hypothesis that deficits in emotion and face recognition for individuals with ASD are related to fundamental differences in information processing. We discuss implications of this finding in a VR environment with regards to potential future applications and paradigms targeting not just enhanced performance, but enhanced social information processing within intelligent systems capable of adaptation to individual processing differences.
