What factors contribute to redundant target processing speed besides statistical facilitation? One possibility is that multiple percepts may drive these effects. Another, although not mutually exclusive hypothesis, is that cross-channel cueing from one modality to another may influence response times. We implemented an auditory-visual detection task using the sound-induced flash illusion to examine whether one or both of these possibilities contributes to changes in processing speed; we did so by examining the data of individual participants. Our results indicated shorter response times in several participants when multiple flashes were perceived in the standard sound-induced flash illusion, thereby replicating previous work in the literature. Additionally, we found evidence for faster responses in several participants when carrying out the same analysis in trials in which 1 beep was presented with 2 real flashes. Overall, our analysis indicates that some observers benefit from cross-modal facilitation, whereas others may benefit from a combination of cross-modal facilitation and increased perceptual judgments.

感知次数或跨模态听觉提示会影响视听处理速度吗？

除了统计上的便利之外，还有哪些因素有助于冗余目标处理速度？一种可能性是多种感知可能会导致这些影响。另一个虽然不是互斥的假设，但从一个模态到另一个模态的跨通道提示可能会影响响应时间。我们使用声音诱发的幻觉执行听觉视觉检测任务，以检查这两种可能性中的一种还是两种都有助于处理速度的变化；我们通过检查单个参与者的数据来做到这一点。我们的结果表明，在标准的声音诱发的闪光错觉中感知到多次闪光时，几个参与者的响应时间较短，从而复制了文献中的先前工作。另外，我们发现有证据表明，在进行1次哔哔声和2次真实闪烁的试验中进行相同分析时，多个参与者的反应更快。总体而言，我们的分析表明，一些观察者会受益于跨模式促进，而其他观察者可能会受益于跨模式促进和更多的感知判断。
