We investigated how sensitive visual processing is to spatiotemporal disruptions in ongoing visual events. Prior work has demonstrated that participants often miss spatiotemporal disruptions in videos presented in the form of scene edits or disruptions during saccades. Here, we asked whether this phenomenon generalizes to spatiotemporal disruptions that are not tied to saccades. In two flicker paradigm experiments, participants were instructed to identify spatiotemporal disruptions created when videos either jumped forward or backward in time. Participants often missed the jumps, and forward jumps were reported less frequently compared with backward jumps, demonstrating that a flicker paradigm produces effects similar to a saccade contingent disruption paradigm. These results suggest that difficulty detecting spatiotemporal disruptions is a general phenomenon that extends beyond trans-saccadic events.
我们研究了视觉处理对正在进行的视觉事件的时空干扰有多敏感。先前的研究表明,参与者经常会错过以场景编辑形式呈现的视频或在扫视过程中出现的时空干扰。在这里,我们想知道这种现象是否适用于与扫视无关的时空干扰。在两个闪烁范式实验中,参与者被指示识别视频向前或向后跳跃时产生的时空干扰。参与者经常错过这些跳跃,并且向前跳跃的报告频率低于向后跳跃,这表明闪烁范式产生的效果类似于与扫视相关的干扰范式。这些结果表明,检测时空干扰的困难是一种普遍现象,它不仅限于跨扫视事件。
