患有自闭症谱系障碍（ASD）的个体表现出感觉处理的改变，包括不同感觉方式之间信息整合的变化。在目前的研究中，我们使用声音诱导的闪光错觉来评估ASD儿童和典型发育（TD）对照组的多感觉整合。31名ASD儿童和31名年龄和智商匹配的TD儿童（平均年龄= 12岁）接受了简单的视觉检查（即，闪光）和听觉（即，beep）不同数量的刺激。在虚幻的条件下，一次闪光会发出2-4声蜂鸣。在TD儿童中，这些条件通常会导致多次闪光的感知，这意味着视觉和听觉的感知融合。在本研究中，ASD儿童明显不太可能察觉到相对于TD控制的错觉，这表明，多感觉整合和跨模态绑定可能是较弱的一些ASD儿童。这些结果进行了讨论的背景下，以前的研究结果为多感觉整合在ASD和未来的研究方向。
Individuals with autism spectrum disorders (ASD) exhibit alterations in sensory processing, including changes in the integration of information across the different sensory modalities. In the current study, we used the sound-induced flash illusion to assess multisensory integration in children with ASD and typically-developing (TD) controls. Thirty-one children with ASD and 31 age and IQ matched TD children (average age = 12 years) were presented with simple visual (i.e., flash) and auditory (i.e., beep) stimuli of varying number. In illusory conditions, a single flash was presented with 2–4 beeps. In TD children, these conditions generally result in the perception of multiple flashes, implying a perceptual fusion across vision and audition. In the present study, children with ASD were significantly less likely to perceive the illusion relative to TD controls, suggesting that multisensory integration and cross-modal binding may be weaker in some children with ASD. These results are discussed in the context of previous findings for multisensory integration in ASD and future directions for research.
