空间和时间的交互作用影响幅度感知：(1)曝光时间越长，感知到的线长越长，反之亦然；(2)线长越短，感知曝光时间越短。先前的研究表明，人类视觉中的时空相互作用是不对称的；空间认知对时间认知的影响大于时间认知对空间认知的影响（Merritt et al.,）。是什么使得相互作用不对称？在这项研究中，参与者被要求判断不同长度的线条的暴露时间，或判断不同暴露时间的线条的长度；判断任务相关刺激程度在任务无关刺激程度上的变化。在配对空间和时间任务中，任务相关和不相关的刺激值的范围是共同的。在我们的假设中，时空信息显著性的不平衡将导致时空相互作用的不对称。为了评估显著性，对任务难度进行了评定。相关刺激的显著性越高，辨别任务的难度就越低，反之亦然。一个任务中不相关刺激的显著性会反映在另一个任务的难度上，在成对的任务中。如果不相关刺激的显著性高，配对任务的难度就会低，反之亦然。结果支持我们的假设；当时间任务难度显著高于空间任务难度时，空间认知对时间认知的影响不对称。
The interaction of space and time affects perception of extents: (1) the longer the exposure duration, the longer the line length is perceived and vice versa; (2) the shorter the line length is, the shorter the exposure duration is perceived. Previous studies have shown that space-time interactions in human vision are asymmetrical; spatial cognition has a larger effect on temporal cognition rather than vice versa (Merritt et al.,). What makes the interactions asymmetrical? In this study, participants were asked to judge exposure duration of lines that differed in length or to judge the lengths of the lines with different exposure time; to judge the task-relevant stimulus extents that also varied in the task-irrelevant stimulus extents. Paired spatial and temporal tasks in which the ranges of task-relevant and -irrelevant stimulus values were common, were conducted. In our hypothesis, the imbalance in saliency of spatial and temporal information would cause asymmetrical space-time interaction. To assess the saliency, task difficulty was rated. If saliency of relevant stimuli is high, the difficulty of discrimination task would be low, and vice versa. The saliency of irrelevant stimuli in one task would be reflected in the difficulty of the other task, in the pair of tasks. If saliency of irrelevant stimuli is high, the difficulty of paired task would be low, and vice versa. The result supports our hypothesis; spatial cognition asymmetrically affected on temporal cognition when the difficulty of temporal task was significantly higher than that of spatial task.
