The aim of the present study was to test how the perception of an emotional stimulus colors the temporal context of judgment and modifies the participant's perception of the current neutral duration. Participants were given two ready-set-go tasks consisting of a distribution of short (0.5-0.9 s) or long sample intervals (0.9-1.3 s) with an overlapping 0.9-s interval. Additional intervals were introduced in the temporal distribution. These were neutral for the two temporal tasks in a control condition and emotional for the short, but not the long temporal task in an emotion condition. The results indicated a replication of a kind of Vierordt's law in the control condition, i.e., the temporal judgment toward the mean of the distribution of sample intervals (central tendency effect). However, there was a shift in the central tendency effect in the emotion condition indicating a general bias in the form of an overestimation of current intervals linked to the presence of a few emotional stimuli among the previous intervals. This finding is entirely consistent with timing mechanisms driven by prior duration context, particularly experience of prior emotional duration.
本研究的目的是测试情绪刺激的感知如何影响判断的时间背景，并改变参与者对当前中性持续时间的感知。参与者被给予两个准备就绪即开始的任务，任务包含短（0.5 - 0.9秒）或长样本间隔（0.9 - 1.3秒）的分布，其中有一个0.9秒的重叠间隔。在时间分布中引入了额外的间隔。在控制条件下，这些间隔对两个时间任务是中性的；在情绪条件下，对短时间任务的间隔是情绪化的，但对长时间任务不是。结果表明在控制条件下重复了一种菲奥尔特定律，即对样本间隔分布均值的时间判断（集中趋势效应）。然而，在情绪条件下集中趋势效应发生了偏移，表明存在一种普遍偏差，表现为高估当前间隔，这与之前间隔中存在一些情绪刺激有关。这一发现与由先前持续时间背景驱动的计时机制完全一致，特别是先前情绪持续时间的经验。
