声诱发闪光错觉（SiFI）是一种听觉主导的视听整合现象，可以作为视听整合的可靠指标。尽管之前的研究发现太极拳运动对认知加工（例如执行功能）有促进作用，但太极拳运动对早期知觉加工的影响还有待研究。本研究采用经典的 SiFI 范式来研究长期太极拳练习对老年人多感觉统合的影响。我们将具有长期太极拳锻炼经验的老年人与长期步行锻炼的老年人进行了比较。结果表明，融合错觉条件下，太极组的准确率高于对照组，这主要是由于对闪光的感知敏感性增加。然而，两组之间的裂变错觉没有显着差异。这些结果表明，太极拳练习对裂变和融合错觉的影响不同，这归因于参与者的闪光辨别能力与其相关。本研究提供了初步证据，表明长期太极拳练习可以改善老年人的多感觉整合，这种整合发生在早期知觉处理中。
Sound-induced flash illusion (SiFI) is an auditory-dominated audiovisual integration phenomenon that can be used as a reliable indicator of audiovisual integration. Although previous studies have found that Tai Chi exercise has a promoting effect on cognitive processing, such as executive functions, the effect of Tai Chi exercise on early perceptual processing has yet to be investigated. This study used the classic SiFI paradigm to investigate the effects of long-term Tai Chi exercise on multisensory integration in older adults. We compared older adults with long-term Tai Chi exercise experience with those with long-term walking exercise. The results showed that the accuracy of the Tai Chi group was higher than that of the control group under the fusion illusion condition, mainly due to the increased perceptual sensitivity to flashes. However, there was no significant difference between the two groups in the fission illusion. These results indicated that the fission and fusion illusions were affected differently by Tai Chi exercise, and this was attributable to the association of the participants' flash discriminability with them. The present study provides preliminary evidence that long-term Tai Chi exercise improves older adults' multisensory integration, which occurs in early perceptual processing.
