Recent experiences bias the perception of following stimuli, as has been verified in various kinds of experiments in visual perception. This phenomenon, known as serial dependence, may reflect mechanisms to maintain perceptual stability. In the current study, we examined several key properties of serial dependence in temporal perception. Firstly, we examined the source of the serial dependence effect in temporal perception. We found that perception without motor reproduction is sufficient to induce the sequential effect; motor reproduction caused a stronger effect and is achieved by biasing the perception of the future target duration rather than directly influencing the subsequent movement. Secondly, we ask how working memory influences serial dependence in a temporal reproduction task. By varying the delay time between standard duration and the reproduction, we showed that the strength of serial dependence is enhanced as the delay increased. Those features of serial dependence are consistent with what has been observed in visual perceptual tasks, for example, orientation perception or location perception. The similarities between the visual and the timing tasks may suggest a similar neural coding mechanism of magnitude between the visual stimuli and the duration.
近期经验会影响对后续刺激的感知，这在各种视觉感知实验中已得到验证。这种现象被称为序列依赖，可能反映了维持感知稳定性的机制。在当前的研究中，我们考察了时间感知中序列依赖的几个关键特性。首先，我们研究了时间感知中序列依赖效应的来源。我们发现，没有运动再现的感知足以引起顺序效应；运动再现会产生更强的效应，它通过偏向对未来目标持续时间的感知来实现，而不是直接影响后续运动。其次，我们询问工作记忆如何影响时间再现任务中的序列依赖。通过改变标准持续时间和再现之间的延迟时间，我们表明随着延迟时间的增加，序列依赖的强度会增强。序列依赖的这些特征与在视觉感知任务中观察到的特征一致，例如，方向感知或位置感知。视觉任务和定时任务之间的相似性可能表明，视觉刺激和持续时间之间存在类似的数量级神经编码机制。
