Serial dependence biases current perception based on recent experiences, creating continuity in subjective experience. Although extensively studied in vision across tasks such as numerosity, orientation discrimination, and attractiveness, its effect on visual time perception remains partially unexplored. Here, we investigated serial dependence in visual temporal perception, using two common tasks: temporal interval duration discrimination and temporal reproduction. In the discrimination task, participants judged whether the second of three visual stimuli was longer or shorter than the third, with the first stimulus being irrelevant, to induce serial dependence on the second stimulus. In the temporal reproduction task, participants were asked to reproduce an interval presented between two visual stimuli by pressing a button. Given the debate concerning the origin of the serial dependence effect and possible relation with memory processing, we also investigated the relationship between serial dependence and working memory capacity using a Corsi test. Our results showed that serial dependence does occur in visual time perception, but no relationship was found between the effect of the two tasks and memory retention capacity. The lack of correlation between serial dependence effects suggests that different processes may be involved in serial dependence across the two types of tasks.
序列依赖性基于近期经历偏向当前感知，从而在主观体验中创造连续性。尽管在诸如数字、方向辨别和吸引力等任务的视觉领域已得到广泛研究，但其对视觉时间感知的影响仍部分未被探索。在此，我们使用两项常见任务研究了视觉时间感知中的序列依赖性：时间间隔时长辨别和时间再现。在辨别任务中，参与者判断三个视觉刺激中的第二个是否比第三个长或短，第一个刺激无关紧要，以此诱导对第二个刺激的序列依赖性。在时间再现任务中，参与者被要求通过按按钮来再现两个视觉刺激之间呈现的间隔。鉴于关于序列依赖性效应起源的争论以及与记忆处理的可能关系，我们还使用科西测试研究了序列依赖性与工作记忆容量之间的关系。我们的结果表明，序列依赖性确实存在于视觉时间感知中，但未发现两项任务的效应与记忆保持容量之间存在关联。序列依赖性效应之间缺乏相关性表明，在这两种类型的任务中，序列依赖性可能涉及不同的过程。
