This study examines whether the modality effect can be used to improve visual time perception. In Experiment 1, we used a time-reproduction task to explore the accuracy (i.e., deviation of reproduced time from veridical time) and precision (i.e., variability of reproduced time) of time perception under auditory, visual, or audiovisual conditions. Results confirmed the existence of a modality effect. Experiments 2a and 2b and Experiment 3 examined whether adding auditory stimuli improves visual time perception. In Experiments 2a and 2b, participants were required to sound when the visual stimuli appeared. Results showed that the addition of sound to visual stimuli perception is associated with higher time perception accuracy than viewing visual stimuli alone. Given that sounding is not always applicable, we conducted Experiment 3, with participants asked to imagine sounds instead of sounding. Results showed that imaginary sounds improved accuracy. However, in Experiments 2a, 2b, and 3, neither sounding nor imagining sounds changed the precision of time perception. The findings of this study indicate that adding auditory stimuli reliably improves the accuracy of visual-time perception, irrespective of whether the sound is real or imagined.
本研究考察了感觉模态效应是否可用于改善视觉时间知觉。在实验 1 中，我们使用时间复制任务来探索在听觉、视觉或视听条件下时间知觉的准确性（即复制时间与真实时间的偏差）和精密度（即复制时间的可变性）。结果证实了感觉模态效应的存在。实验 2a、2b 和实验 3 考察了添加听觉刺激是否能改善视觉时间知觉。在实验 2a 和 2b 中，要求参与者在视觉刺激出现时发声。结果表明，与单独观看视觉刺激相比，将声音添加到视觉刺激感知中与更高的时间知觉准确性相关。鉴于发声并非总是适用，我们进行了实验 3，要求参与者想象声音而不是发声。结果表明，想象声音可以提高准确性。然而，在实验 2a、2b 和 3 中，发声或想象声音都没有改变时间知觉的精密度。本研究的结果表明，添加听觉刺激可可靠地提高视觉时间知觉的准确性，无论声音是真实的还是想象的。
