Time discrimination, a critical aspect of auditory perception, is influenced by numerous factors. Previous research has suggested that musical experience can restructure the brain, thereby enhancing time discrimination. However, this phenomenon remains underexplored. In this study, we seek to elucidate the enhancing effect of musical experience on time discrimination, utilizing both behavioral and electroencephalogram methodologies. Additionally, we aim to explore, through brain connectivity analysis, the role of increased connectivity in brain regions associated with auditory perception as a potential contributory factor to time discrimination induced by musical experience. The results show that the music-experienced group demonstrated higher behavioral accuracy, shorter reaction time, and shorter P3 and mismatch response latencies as compared to the control group. Furthermore, the music-experienced group had higher connectivity in the left temporal lobe. In summary, our research underscores the positive impact of musical experience on time discrimination and suggests that enhanced connectivity in brain regions linked to auditory perception may be responsible for this enhancement.

音乐体验增强时间辨别力：皮层反应的证据


时间辨别是听觉感知的一个重要方面，受到许多因素的影响。先前的研究表明，音乐体验可以重组大脑，从而增强时间辨别力。然而，这种现象仍未得到充分研究。在这项研究中，我们试图利用行为和脑电图方法来阐明音乐体验对时间辨别的增强作用。此外，我们的目标是通过大脑连接分析，探索与听觉感知相关的大脑区域连接性增加的作用，作为音乐体验引起的时间歧视的潜在影响因素。结果表明，与对照组相比，有音乐经历的组表现出更高的行为准确性、更短的反应时间以及更短的 P3 和错配反应潜伏期。此外，有音乐经历的组左颞叶的连接性更高。总之，我们的研究强调了音乐体验对时间辨别的积极影响，并表明与听觉感知相关的大脑区域连接性的增强可能是这种增强的原因。
