The present study used the Dot-Probe paradigm to explore attentional allocation to faces compared with non-social images in high-functioning individuals with autism spectrum disorder (ASD) and typically developing controls. There was no evidence of attentional bias in either group when stimuli were presented at individually calculated sub-threshold levels. However, at supra-threshold presentation (200 ms), a face bias was found for control participants but not for those with ASD. These results add to evidence of reduced social interest in ASD, relative to controls, and further demonstrate when atypical social processing arises in the attentional time course.
本研究使用点探测范式来比较自闭症谱系障碍（ASD）高功能个体和典型发育对照者对人脸与非社交图像的注意力分配。当刺激呈现于个体计算的亚阈值水平时，两组均没有注意偏向的证据。然而，在超阈值呈现（200 毫秒）时，对照组参与者表现出对人脸的偏向，而 ASD 组则没有。这些结果进一步证明了 ASD 患者相对于对照组对社交的兴趣减少，并且表明在注意力时间进程中出现了异常的社交处理。
