相对于听觉，视觉在感觉运动计时（例如将手指运动与时间规则序列同步）方面被认为不太可信。视觉运动计时需要随着时间的推移保持注意力，而在传统的视觉运动计时任务设置中，持续的视觉注意力可能无法很好地保持，其中闪烁的视觉刺激由短暂呈现的闪光和较长的空白期组成。在本研究中，在实验 1 中通过改变闪光的颜色而不是其消失来仔细控制由于闪光消失而导致的潜在注意力缺失，或者在实验 2 中通过添加一个额外的连续呈现的注视点作为闪光消失时的外部注意力提示。两项实验均发现视觉运动计时性能有所改善。这一发现表明，增强的持续视觉注意力在改善视觉运动计时方面发挥着重要作用，通过这种方式，视觉也可能成为处理感觉运动相互作用中时间信息的可靠方式。
Relative to audition, vision is considered much less trustworthy in sensorimotor timing such as synchronizing finger movements with a temporally regular sequence. Visuomotor timing requires maintaining attention over time, whereas the sustained visual attention may not be well held in conventional visuomotor timing task settings where flashing visual stimuli consisted of a briefly presented flash and a long blank period. In the present study, the potential attentional lapses in time due to the disappearance of the flash were carefully controlled in Experiment 1 by changing the color of the flash instead of its disappearance, or in Experiment 2 by adding an additional continuously presented fixation point serving as an external attentional cue when the flash disappeared. Improvement of visuomotor timing performance was found in both experiments. The finding suggests a role of enhanced sustained visual attention in improving visuomotor timing, by which vision could also be a trustworthy modality for processing temporal information in sensorimotor interactions.
