Cognition of space and time affect each other; a line with longer length appears to be longer in exposure duration (space on time), and a line with longer exposure duration appears to be longer in length (time on space). This cognitive interaction is known to be asymmetric; the effect of space on time is larger than that of time on space. We conjectured that this asymmetry is not intrinsic but may depend on the saliency of relevant signals. Participants were asked to judge the visual exposure duration of lines that varied in length or the lengths of the lines with different exposure times. The ranges of task-relevant and -irrelevant stimulus values were the same in the spatial and temporal tasks. Task difficulty was also evaluated by subjective rating. We found that duration affected the judgment of length more than vice versa, when the spatial task was significantly more difficult than the temporal task. Together with our previous results that showed the opposite effect, our conjecture is supported that the saliency of stimuli should affect the balance of interactions.

时间认知对空间认知的影响远不及反之：任务相关刺激显着性的影响。

对时间和空间的认识相互影响；长度较长的线显示的曝光时间（时间间隔）较长，而线较长的线显示的曝光时间（时间间隔）较长。这种认知互动是不对称的。时间对空间的影响大于时间对空间的影响。我们推测这种不对称性不是固有的，但可能取决于相关信号的显着性。要求参与者判断长度变化的线的视觉曝光持续时间或具有不同曝光时间的线的长度。与任务相关和与无关的刺激值的范围在空间和时间任务中是相同的。任务难度也通过主观评价进行评估。我们发现，持续时间对长度的判断的影响大于反之，当空间任务比时间任务困难得多时。连同我们先前显示出相反效果的结果，我们的猜测得到支持，即刺激的显着性应该影响相互作用的平衡。
