持续时间知觉文献中的几个发现表明，当参与者做出关于时间的决定时，他们依赖于内部的参考记忆来获得时间，而不仅仅是依赖于当前的物理刺激。根据最近的描述，这样的内部基准是通过集成来自先前试验和当前试验的持续时间信息的连续动态更新过程形成的。在目前的工作中，我们展示了这样的动力学机制如何解释经典但尚未解决的Vierordt效应，即对相对较短的时间间隔的高估和对相对较长的时间间隔的低估。我们进行了一项实验，通过时间复制任务来检验这一点和相关的预测。具体地说，参与者被展示了两个连续的时间间隔-标准的S持续时间不变，而C的比较持续时间可变。然而，参与者随后被提示再现两个呈现的刺激中的一个，而不是进行比较判断。复制不仅受到要复制的刺激的时间位置的影响，而且还受到早期试验中呈现的刺激的影响。这些结果支持动态更新的内部参照物的概念，这是我们对过去时间的判断的基础，这也可能是维耶罗特效应的基础。(C)2013爱思唯尔B.V.保留所有权利。
Several findings from duration perception literature suggest that when making decisions about time, participants rely on an internal reference memory for time rather than merely on the current physical stimuli. According to a recent account, such an internal reference is formed by a continuous dynamic updating process that integrates duration information from previous trials and the current trial. In the present work, we show how such a dynamic mechanism can account for the classical yet unresolved Vierordt effect, which refers to the overestimation of relatively short and the underestimation of relatively long temporal intervals. We conducted an experiment to examine this and related predictions by means of a temporal reproduction task. Specifically, participants were presented with two successive time intervals - a standard s with constant duration and a comparison c with variable duration. Instead of performing a comparison judgment, however, the participants were subsequently cued to reproduce one of the two presented stimuli. Reproductions were affected not only by the temporal position of the to-be-reproduced stimulus, but also by the stimuli presented on earlier trials. These results support the notion of a dynamically updated internal reference underlying our judgments about the time elapsed, which might also be the basis of the Vierordt effect.
