手指敲击与周期性闪烁的视觉刺激的同步比听觉节拍器的同步变化更大。当其中一种节奏作为同步目标，另一种节奏在不同的时间偏移上作为干扰时，观察到强烈的听觉优势。然而，最近有研究表明，视觉运动同步在运动刺激（如连续弹跳的球）下得到显著改善。目前的研究将弹跳球与听觉节拍器进行对比，采用目标-干扰物同步模式，参与者分别是听觉专家（音乐家）和视觉专家（电子游戏玩家和球手）。在两组中，听觉目标刺激的同步性比视觉目标刺激的同步性变化更小。对于音乐家来说，听觉刺激往往比视觉刺激更容易分散注意力，而对于视觉专家来说，情况正好相反。总体而言，干扰物形态不存在主要影响。因此，在干扰同步运动的能力上，分散注意力的时空视觉节奏可以和分散注意力的听觉节奏一样有效，但其有效性也取决于特定模态的专业知识。
Synchronization of finger taps with periodically flashing visual stimuli is known to be much more variable than synchronization with an auditory metronome. When one of these rhythms is the synchronization target and the other serves as a distracter at various temporal offsets, strong auditory dominance is observed. However, it has recently been shown that visuomotor synchronization improves substantially with moving stimuli such as a continuously bouncing ball. The present study pitted a bouncing ball against an auditory metronome in a target-distracter synchronization paradigm, with the participants being auditory experts (musicians) and visual experts (video gamers and ball players). Synchronization was still less variable with auditory than with visual target stimuli in both groups. For musicians, auditory stimuli tended to be more distracting than visual stimuli, whereas the opposite was the case for the visual experts. Overall, there was no main effect of distracter modality. Thus, a distracting spatiotemporal visual rhythm can be as effective as a distracting auditory rhythm in its capacity to perturb synchronous movement, but its effectiveness also depends on modality-specific expertise.
