Our primary purpose in this study was to determine whether trained dancers differed from untrained non-dancers in their ability to accurately control motor timing during finger and heel tapping tasks, both with and without slow isochronous auditory stimuli. Dancers and non-dancers were instructed to synchronize their taps with isochronous auditory stimuli under three conditions: 30, 40, and 50 BPM. After the synchronization phase, participants were asked to continue tapping without the auditory sequences. On the synchronization task, the tapping onset of both groups lagged behind the stimulus onset in all tempo conditions. In all conditions, dancers showed more accurate and stable beat synchronization and continuation than non-dancers. As the tempo condition slowed down (from 50 to 30 BPM), synchronization accuracy decreased while synchronization and continuation variability increased. Unlike for novices, dancers showed no difference between the finger and heel tapping synchronization tasks. During the continuous tasks, their timing accuracy was higher for heel than for finger tapping. Collectively, these findings suggest that dance training, which involves synchronizing bodily movements based on rhythm, may lead to an accumulation of experience that enhances specific sensorimotor skills related to synchronizing movements with external stimuli or continuing rhythmic movements temporally.
我们在这项研究中的主要目的是确定受过训练的舞者与未经训练的非舞者在手指和脚跟敲击任务中准确控制运动时间的能力是否存在差异，包括有无慢等时听觉刺激。舞者和非舞者被要求在三种条件下根据等时听觉刺激进行同步敲击：30、40 和 50 BPM。在同步阶段之后，要求参与者在没有听觉序列的情况下继续敲击。在同步任务中，在所有节奏条件下，两组的敲击起始都滞后于刺激起始。在所有条件下，舞者的节拍同步和延续比非舞者更准确和稳定。随着节奏条件的减慢（从 50 到 30 BPM），同步准确性降低，而同步和延续变异性增加。与新手不同，舞者在手指和脚跟敲击同步任务之间没有差异。在连续任务中，他们的脚跟敲击的定时准确性高于手指敲击。总的来说，这些发现表明，舞蹈训练涉及根据节奏协调身体运动，可能会积累经验，从而增强与外部刺激同步运动或继续进行节奏运动的特定感觉运动技能。
