Abrupt click sounds can improve the visual processing of flashes in several ways. Here, we examined this in high functioning adolescents with Autism Spectrum Disorders (ASD) using three tasks: (1) a task where clicks improve sensitivity for visual temporal order (temporal ventriloquism); (2) a task where a click improves visual search (pip-and-pop), and (3) a task where a click speeds up the visual orienting to a peripheral target (clock reading). Adolescents with ASD were, compared to adolescents with typical development (TD), impaired in judgments of visual temporal order, but they were unimpaired in visual search and orienting. Importantly, in all tasks visual performance of the ASD group improved by the presence of clicks by at least equal amounts as in the TD group. This suggests that adolescents and young adults with ASD show no generalized deficit in the multisensory integration of low-level audiovisual stimuli and/or the phasic alerting by abrupt sounds.
突发的咔嗒声可以通过多种方式改善闪光的视觉处理。在这里，我们使用三种任务来研究这一点：（1）一种咔嗒声可以提高视觉时间顺序敏感性的任务（时间错觉）；（2）一种咔嗒声可以改善视觉搜索的任务（pip-and-pop）；（3）一种咔嗒声可以加速对周围目标进行视觉定向的任务（时钟阅读）。与具有典型发育（TD）的青少年相比，自闭症谱系障碍（ASD）的青少年在视觉时间顺序判断方面存在障碍，但在视觉搜索和定向方面没有障碍。重要的是，在所有任务中，ASD 组的视觉表现通过咔嗒声的存在至少与 TD 组一样得到了改善。这表明，患有 ASD 的青少年和年轻人在整合低水平视听刺激和/或突发声音的相位警觉方面没有普遍的缺陷。
