心理时间一方面是为了知觉事件的连续性而建构的一种幻觉，另一方面确乎能在事件表征中发挥重要作用，帮助人们适应动态变化的世界。然而，个体的主观时间体验如何影响对视觉事件的表征呢？本研究将通过探索主观时间感对视觉空间运动表征动量现象的影响来回答这一问题。对视觉空间运动的表征动量现象指，观察者在观察一个物体在空间中运动的刺激之后，对物体的最终位置会产生错误记忆，其所记忆的位置与实际的位置相比会发生沿着运动轨迹和方向的移位。根据前人研究，我们预期时间感知会影响表征动量现象。

本研究参考经典方法，用不同节奏的声音刺激操纵被试的时间感知，并以运动的圆点为刺激，要求被试在表征动量任务中用鼠标点击圆点消失时的位置，探索时间感知的状态性变化对表征动量任务的影响。而且，本研究还通过时距估计任务测量被试主观时间感的个体差异，探索时间感知的个体差异对表征动量任务的影响。此外，本研究让被试进行速度迫选任务，选择不同声音刺激下客观速度相同的运动圆点哪个速度更快，作为本研究实验操纵的操纵检验。

结果发现，声音刺激的节奏能影响主观时间感，但不能显著影响表征动量任务中的移位量。本文从实验方法、注意调控和跨通道整合角度讨论了这一结果背后的几种可能原因。不过，结果还发现，个体的特质性时间感知与移位量存在显著关联，这揭示了时间感的个体差异可能是运动视知觉个体差异的来源之一，并提示未来可以进一步探索两者的个体差异之间的关联，以深入理解两者及时空信息整合和交互的机制。

Although psychological time is an illusion that is constructed in order to perceive the continuity of events, it does play a crucial rule in event representation, helping people adapt to the dynamic world. However, the effect of subjective time experience on the event perception is not fully investigated. Representational momentum (RM) is an example of the localization bias phenomenon of dynamic events, which is a memory distortion that the final position of a moving object is perceived and remembered to be further along the moving trajectory compared to the actual position. According to previous findings, we hypothesized that rhythmic auditory stimuli affects subjective sense of time and influences the magnitude of displacement in the RM task.

We manipulated subjective sense of time by presenting rhythmic auditory stimuli with different tempo when the participants viewed short videos of a moving dot and complete RM tasks by pointing the remembered final location of the dot using cursor. The present study also measured individual difference in subjective sense of time with a duration reproduction task, and examined the relation between individual difference in subjective sense of time and that of RM. As manipulation check, participants are instructed to do a 2AFC task, in which they will choose between 2 moving dots with the same speed but accompanied by different auditory tempo, about which one has a higher speed.

The result shows that the sound stimuli can induce a change of perceived speed, but not the displacement in the RM task. We discussed the potential reasons from the aspects of experimental design, multisensory integration and attentional modulation. However, it is found that the individual difference in the subjective sense of time is correlated with displacement, consistent with the hypothesized link between subjective sense of time and visuospatial processing. The result may inspire further investigation in the mechanism of time and event perception, and the integration and interaction of temporal-spatial information.
