为了探讨数秒内时间加工分段性问题,文章首先指出1/3、1/2、1及3秒分界点或者20-60毫秒和2-3秒时间窗分别是从“时间信息加工”和“信息加工的时间特性”角度区分时间加工分段性的重要常数,然后对这些常数进行了概述和评价,最后剖析了两种视角的区别和联系,并展望了未来研究方向。 In order to explore the problem of time-processing segmentation in a few seconds, the article first points out that 1/3, 1/2, 1 and 3 seconds cutoff points or 20-60 ms and 2-3 seconds time windows are from “time information processing” And “the time characteristic of information processing”, the important constants of time processing segmentation are distinguished, and then the constants are summarized and evaluated. Finally, the differences and relations between the two perspectives are analyzed and the future research directions are prospected.
