The perception of and reaction to objects creates bindings of (object) features and responses, also called event files. In this context, is a so far understudied feature. We conducted four experiments to investigate whether the duration of visual stimuli is also integrated into such event files. Experiments 1, 2, and 4 used a simple colour classification task and in Experiment 3 the location of a stimulus had to be classified. In all Experiments, the presentation duration of the stimuli (coloured circles) was either short (20 ms) or long (300 ms). We expected partial repetition costs as an indicator of binding. That is, performance should be better when both colour (Experiment 3: location) and duration repeat or alternate relative to partial repetitions. Results showed no partial repetition costs in Experiments 1 and 3, indicating no integration of duration into visual event files. Experiments 2 and 4 revealed partial repetition costs. Performance was better when Colour and Duration repeated compared with a partial repetition. What distinguishes the latter two experiments from the former is that the coloured stimuli could change their presentation location. The results of all four experiments show a pattern that duration can be integrated into visual event files depending on two criteria: The experimental context holds the possibility of a location change of the target stimulus (Experiments 2 and 4) and the location itself is not response relevant (Experiment 3). The role of location changes for the integration of temporal stimulus features into visual event files is discussed.
对物体的感知和反应会产生（物体）特征和反应的绑定，也称为事件文件。在这种情况下，持续时间是一个迄今为止研究较少的特征。我们进行了四项实验，以调查视觉刺激的持续时间是否也被整合到这种事件文件中。实验 1、2 和 4 使用了简单的颜色分类任务，而实验 3 则需要对刺激的位置进行分类。在所有实验中，刺激（彩色圆圈）的呈现持续时间要么很短（20 毫秒），要么很长（300 毫秒）。我们预计部分重复成本将作为绑定的指标。也就是说，当颜色（实验 3：位置）和持续时间重复或交替相对于部分重复时，表现应该更好。实验 1 和 3 没有显示出部分重复成本，这表明持续时间没有被整合到视觉事件文件中。实验 2 和 4 显示出部分重复成本。与部分重复相比，当颜色和持续时间重复时，表现更好。后两个实验与前两个实验的区别在于，彩色刺激可以改变它们的呈现位置。四项实验的结果显示出一种模式，即持续时间可以根据两个标准整合到视觉事件文件中：实验背景提供目标刺激位置变化的可能性（实验 2 和 4），并且位置本身与反应无关（实验 3）。讨论了位置变化对将时间刺激特征整合到视觉事件文件中的作用。
