In this study we investigate whether persons with autism spectrum disorder (ASD) perceive social images differently than control participants (CON) in a graded perception task in which stimuli emerged from noise before dissipating into noise again. We presented either social stimuli (humans) or non-social stimuli (objects or animals). ASD were slower to recognize images during their emergence, but as fast as CON when indicating the dissipation of the image irrespective of its content. Social stimuli were recognized faster and remained discernable longer in both diagnostic groups. Thus, ASD participants show a largely intact preference for the processing of social images. An exploratory analysis of response subsets reveals subtle differences between groups that could be investigated in future studies.

在这项研究中，我们调查了在分级感知任务中，自闭症谱系障碍 (ASD) 患者对社会图像的感知是否与对照参与者 (CON) 不同，在该任务中，刺激从噪音中出现，然后再次消散为噪音。我们提出了社会刺激（人类）或非社会刺激（物体或动物）。ASD 在图像出现期间识别图像的速度较慢，但​​在指示图像消散时与 CON 一样快，无论其内容如何。在两个诊断组中，社会刺激的识别速度更快，并且可识别的时间更长。因此，ASD 参与者对社交图像的处理表现出基本完整的偏好。响应子集的探索性分析揭示了可以在未来研究中研究的组之间的细微差异。
