同步行动对于日常生活很重要。一般来说，听觉域对于编码时间信息更加敏感，并且之前的研究表明听觉-运动同步比视觉-运动同步精确得多。有趣的是，添加运动信息可以改善与视觉刺激的同步，而听觉方式的优势似乎会减弱。然而，添加运动信息是否也能改善听觉-运动同步仍然未知。这项研究在听觉和视觉方式上比较了敲击准确性与静止或移动刺激。参与者被要求在静止状态下与声音或闪光的出现同步敲击，而在运动状态下这些刺激被视为从一侧移动到另一侧。结果表明，正如之前的研究所示，与移动视觉刺激同步敲击比使用静止视觉刺激同步敲击更加准确。然而，使用移动听觉刺激的敲击明显比使用静止听觉刺激的敲击差。尽管运动信息损害了音频-运动同步，但听觉模态相对于视觉模态的优势仍然存在。这些发现可能是听觉领域时间分辨率更高的结果，这可能是由于大脑听觉和视觉通路的生理和结构差异造成的。
Synchronised action is important for everyday life. Generally, the auditory domain is more sensitive for coding temporal information, and previous studies have shown that auditory-motor synchronisation is much more precise than visuo-motor synchronisation. Interestingly, adding motion information improves synchronisation with visual stimuli and the advantage of the auditory modality seems to diminish. However, whether adding motion information also improves auditory-motor synchronisation remains unknown. This study compared tapping accuracy with a stationary or moving stimulus in both auditory and visual modalities. Participants were instructed to tap in synchrony with the onset of a sound or flash in the stationary condition, while these stimuli were perceived as moving from side to side in the motion condition. The results demonstrated that synchronised tapping with a moving visual stimulus was significantly more accurate than tapping with a stationary visual stimulus, as previous studies have shown. However, tapping with a moving auditory stimulus was significantly poorer than tapping with a stationary auditory stimulus. Although motion information impaired audio-motor synchronisation, an advantage of auditory modality compared to visual modality still existed. These findings are likely the result of higher temporal resolution in the auditory domain, which is likely due to the physiological and structural differences in the auditory and visual pathways in the brain.
