有人提出，时间知觉的准确性与内感受准确性和迷走神经活动有关。然而，研究超秒范围内的时间感知的研究提供了混合的结果，并且很少有研究研究亚秒范围。此外，也缺乏研究调查之间的关系，时间知觉的精度和内感受准确性。最近的一项神经影像学研究的元分析综述提出了两种类型的时间处理-内源性时间保持机制和外源性时间线索的使用之间的动态相互作用。内感受准确性可能会影响主要时间表示的准确性和精确性，因为它们是基于内源性时间保持机制生成的。时间准确性在适应环境上下文时可以变化。相比之下，时间精度包含一些恒定的噪声，这可能保持与内感受精度的关系。基于这些假设，我们假设内感受准确性将与亚秒范围内的时间精度相关，而迷走神经活动将与时间精度相关。我们使用了时间概括任务，这使我们能够计算与现有研究一致的时间准确性和时间精确性指数，并根据信号检测理论计算参与者的敏感性指数。具体而言，我们研究了（1）内感受准确性是否与时间准确性、时间精确度或敏感性相关，以及（2）静息状态迷走神经活动是否与时间准确性、时间精确度或敏感性相关。结果表明，在亚秒级时间知觉中，内感受准确性与时间准确性和敏感性呈正相关，但与时间准确性无关。迷走神经活动仅与敏感性呈负相关。此外，我们发现了一个温和的影响迷走神经活动和感知持续时间之间的关系的敏感性，影响迷走神经活动和时间准确性之间的关联。这些研究结果表明，作为时间知觉的一个方面，未来的研究应进一步探讨与内感受和迷走神经活动的关系，以及参与者在这种情况下的敏感性等因素的调节作用的重要性。
It has been proposed that accuracy in time perception is related to interoceptive accuracy and vagal activity. However, studies investigating time perception in the supra-second range have provided mixed results, and few studies have investigated the sub-second range. Moreover, there is a lack of studies investigating the relationship between precision in time perception and interoceptive accuracy. A recent meta-analytic review of neuroimaging studies proposed a dynamic interaction between two types of timing processing—an endogenous time keeping mechanism and the use of exogenous temporal cues. Interoceptive accuracy may affect both accuracy and precision of primary temporal representations, as they are generated based on the endogenous time keeping mechanism. Temporal accuracy may vary when adapted to the environmental context. In contrast, temporal precision contains some constant noise, which may maintain the relationship with interoceptive accuracy. Based on these assumptions, we hypothesized that interoceptive accuracy would be associated with temporal precision in the sub-second range, while vagal activity would be associated with temporal accuracy. We used the temporal generalization task, which allowed us to calculate the indices of temporal accuracy and temporal precision in line with the existing research, and also compute the index of participants’ sensitivity according to the signal detection theory. Specifically, we investigated whether (1) interoceptive accuracy would correlate with temporal accuracy, temporal precision, or sensitivity and (2) resting-state vagal activity would correlate with temporal accuracy, temporal precision, or sensitivity. The results indicated that interoceptive accuracy was positively correlated with temporal precision as well as sensitivity, but not with temporal accuracy, in the sub-second range time perception. Vagal activity was negatively correlated only with sensitivity. Furthermore, we found a moderation effect of sensitivity on the relationship between vagal activity and perceived duration, which affected the association between vagal activity and temporal accuracy. These findings suggest the importance of precision as an aspect of time perception, which future studies should further explore in relation to interoception and vagal activity, and of the moderation effects of factors such as participants’ sensitivity in this context.
