As an interdisciplinary research field, music perception involves various disciplines, such as neuroscience, psychology, and even physics. As research on music perception offers us a window into the mechanism of the brain, this study examined Chinese nonmusicians' electroencephalogram α-band activity elicited by tempo variation. This study is the first to demonstrate electrophysiological evidence for the tempo-specific timing hypothesis by showing significant changes in the α-band spectral power during tempo perception. Furthermore, results showed that a larger tempo transformation gave rise to a greater change in α-band spectral power than a smaller tempo transformation.
作为一个跨学科研究领域，音乐感知涉及多个学科，如神经科学、心理学，甚至物理学。由于音乐感知研究为我们提供了一扇了解大脑机制的窗口，本研究考察了中国非音乐专业人士在节奏变化时诱发的脑电图α波段活动。本研究首次通过展示节奏感知过程中α波段频谱功率的显著变化，为节奏特定计时假说提供了电生理证据。此外，结果表明，较大的节奏变化比较小的节奏变化在α波段频谱功率上产生更大的变化。
