背景资料：自自闭症谱系障碍（ASC）的第一次报告以来，人们就注意到了关于自闭症谱系障碍（ASC）患者感觉超敏反应的轶事。随着时间的推移，经验证据支持这样的观点，即与对照组相比，患有ASC的人具有更优越的上级视觉能力。然而，目前还不清楚这些能力是否是感官阈值差异的具体结果方法：本研究调查了n = 15名患有ASC的个体和n = 15名没有ASC的个体的视觉阈值，使用标准化验光测试，即弗赖堡视力和对比度测试，调查基本的低水平视力。个人与ASC有显着更好的视力（20：7）与对照组（20：13）相比，敏锐度，以便上级，它位于该地区报告的猛禽。结论：本研究的结果表明，列入感官超敏反应的诊断标准ASC可能是必要的，基本的标准化测试的感官阈值可以告知因果理论的ASC。
Background: Anecdotal accounts of sensory hypersensitivity in individuals with autism spectrum conditions (ASC) have been noted since the first reports of the condition. Over time, empirical evidence has supported the notion that those with ASC have superior visual abilities compared with control subjects. However, it remains unclear whether these abilities are specifically the result of differences in sensory thresholds (low-level processing), rather than higher-level cognitive processes.Methods: This study investigates visual threshold in n = 15 individuals with ASC and n = 15 individuals without ASC, using a standardized optometric test, the Freiburg Visual Acuity and Contrast Test, to investigate basic low-level visual acuity.Results: Individuals with ASC have significantly better visual acuity (20:7) compared with control subjects (20:13)-acuity so superior that it lies in the region reported for birds of prey.Conclusions: The results of this study suggest that inclusion of sensory hypersensitivity in the diagnostic criteria for ASC maybe warranted and that basic standardized tests of sensory thresholds may inform causal theories of ASC.
