A number of studies have demonstrated atypical perception in individuals with ASD. However, the majority of these studies have presented stimuli to central vision. The aim of the study presented here was to test the sensitivity of peripheral vision in ASD. This was achieved by asking participants to detect brief flashes of light presented between 30 and 85 degrees away from fixation. We found that participants with ASD detected fewer ligh-flashes than the control participants. This deficit was more pronounced in the nasal hemifield than the temporal hemifield. We suggest that the imbalance between nasal and temporal hemifield sensitivity may contribute to the peripheral-field stimulation and lateral glances that are observed in ASD.
一些研究表明，自闭症患者存在非典型感知。然而，这些研究大多数都将刺激呈现给了中央视觉。本研究旨在测试自闭症患者的周边视觉敏感度。我们通过让参与者检测从注视点向外 30 到 85 度之间短暂出现的光闪烁来实现这一目标。我们发现，自闭症患者比对照组参与者检测到的光闪烁更少。这种缺陷在鼻侧视野比颞侧视野更为明显。我们认为，鼻侧和颞侧视野敏感度之间的不平衡可能导致了自闭症患者观察到的周边区域刺激和侧视。
