Atypical visual behaviour has been recently proposed to account for much of social misunderstanding in autism. Using an eye-tracking system and a gaze-contingent lens display, the present study explores self-monitoring of eye motion in two conditions: free visual exploration and guided exploration via blurring the visual field except for the focal area of vision. During these conditions, thirteen students with High Functioning Autism Spectrum Disorders (HFASD) and fourteen typical individuals were presented naturalistic and interactive social stimuli using virtual reality. Fixation data showed a weaker modulation of eye movements according to the conditions in the HFASD group, thus suggesting impairments in self-monitoring of gaze. Moreover, the gaze-contingent lens induced a visual behaviour whereby social understanding scores were correlated with the time spent gazing at faces. The device could be useful for treating gaze monitoring deficiencies in HFASD.
最近有人提出，非典型视觉行为可以解释自闭症患者在社交方面存在的诸多误解。本研究使用眼动追踪系统和基于注视的变焦距透镜显示器，在两种条件下探索个体的眼球运动自我监控：自由视觉探索和通过模糊视野（除注视区域外）进行的引导式探索。在这些条件下，13 名高功能自闭症谱系障碍（HFASD）患者和 14 名典型个体通过虚拟现实呈现了自然和互动的社会刺激。注视数据显示，HFASD 组的眼球运动调节较弱，这表明他们在自我监控眼球运动方面存在障碍。此外，基于注视的变焦距透镜会诱导一种视觉行为，即社交理解得分与注视面部的时间相关。该设备对于治疗 HFASD 的眼球监控缺陷可能有用。
