本研究采用复制时距和数字加工双任务,探讨数字大小影响时距知觉的机制。实验首先呈现不同时距的圆点,然后让被试按键复制圆点呈现的时距,与此同时,对屏幕上出现的数字进行命名(实验1)、奇偶数判断(实验2)、大小判断(实验3)。实验结果发现对数字进行奇偶数判断时,数字大小对时距知觉没有影响;进行数字命名和大小判断任务时,数字大小对时距知觉都产生了影响,并且时距不同,数字大小对时距知觉的影响也不同。该结果表明时距知觉的数字效应与数字加工任务和时距长短有关,呈现出动态变化的过程。
In this study, the double-time copying and digital processing tasks were used to explore the mechanism of digital size affecting time-perception. At first, the experiment presents the dots with different time intervals, and then lets the subjects try to duplicate the time when the dots appear. At the same time, the numbers appearing on the screen are named (Experiment 1), even and odd numbers (Experiment 2) (Experiment 3). The experimental results show that when the numbers are judged by odd and even numbers, the size of the numbers has no effect on the perception of the time-space. When performing the numerical naming and size determination tasks, the size of the numbers has an impact on the perception of the time-space, and the time-interval is different. The impact of perception is also different. The result shows that the digital effect of the perception of time-distance is related to the number of processing tasks and the time-duration of the digital processing, presenting a dynamic process of change.
